As reported in the media, in recent months we have been delighted to support staff and students at the University of Mosul in Iraq who are rebuilding the Department of English after the devastation caused by the so-called Islamic State group . Via the CorpusMOOC and other forms of long-distance support, we have begun to interact with colleagues in Mosul, and to appreciate both the size of the task ahead of them and their determination to succeed. We are now in the process of arranging a month-long visit to Lancaster from two Mosul academics, so that we can strengthen our ties, including by exploring joint projects. Watch this space for updates on the visit and our future joint activities.
This is the second time I have been a part of CASS, which means that this is the second time I’ve written one of these introductory blog pieces. I first worked in CASS in 2016, on an eight-month project with Paul Baker where we looked at the feedback that patients gave about the NHS in England. This was a really fun project to work on – I enjoyed being a part of CASS and working with Paul and made some great friends in the Centre with whom I’m still in contact to this day. Since leaving CASS in October 2016, I completed my PhD in Applied Linguistics in the School of English at the University of Nottingham, which examined the ways that people with diabetes and eating disorders construct their illnesses and identities in online support groups. Following my PhD, I stayed in the School of English at Nottingham, working as a Postdoctoral Research Fellow in the School’s Professional Communication research and consultancy unit.
As you might have guessed from the topic of my doctoral project and my previous activity with CASS, my main research interests are in the areas of corpus linguistics and health communication. I am therefore very excited to return to the Centre now, with its new focus on the application of corpora to the study of health communication. I’m currently working on a new project within the Centre, Representations of Obesity in the News, which explores the ways that obesity and people affected by obesity are represented in the media, focussing in particular on news articles and readers’ responses. I’m very excited to be working on this important project. Obesity is a growing and seemingly ever-topical public health concern, not just in the UK but globally. However, the media’s treatment of the issue can often be stigmatising, making it quite deserving of scrutiny! Yet, our aim in this project isn’t just to take the media to task, but to eventually work with media outlets to advise them on how to cover obesity in a way that is more balanced and informative and, crucially, less stigmatising for people who are affected by it. In this project, we’re also working with obesity charities and campaign groups, which provides a great opportunity to make sure that the focus of our research is not just fit for academic journals but is relevant to people affected by this issue and so can be applied in the ‘real world’, as it were.
So, to finish on more of a personal note, the things I said about myself the last time I wrote one of these blog posts are still true ; I still like walking, I still travel lots, I still read fantasy and science fiction, I still do pub quizzes, my football team are still rubbish and I don’t think I’ve changed that much since the photo used in that piece was taken… Most of all, though, it still excites me to be a part of CASS and I am absolutely delighted to be back.
Last week, the Faculty of Education, The University of Cambridge hosted 13th Teaching and Language Corpora Conference. This wonderful event brought together researchers and practitioners interested in different applications of corpus techniques in the classroom.
Dana Gablasova and I with the help of Irene Marin Cervantes and Tanjun Liu gave a practical workshop introducing the idea of sociolinguistic variation in English language teaching in both A level English language classes as well as in EFL/ESL classes.
This blogpost shows a few snapshots from the workshop as well as an unedited video showing 15 min introduction to the workshop plus the workshop materials in pdf.
On Saturday 12 May 2018, CASS hosted a small training event at Lancaster University for a group of participants, who came from different universities in the UK. We talked about the BNC2014 project and discussed both the theoretical underpinnings as well as the practicalities of corpus design and compilation. Slides from the event are available as pdf here.
The participants then tried in practice what is involved in the compilation of a large general corpus such as the BNC2014. They selected and scanned samples of books from current British fiction, poetry and a range of non-fiction books (history, popular science, hobbies etc.). Once processed, these samples will become a part of the written BNC2014.
Here are some pictures from the event:

The event was supported by ESRC grant no. EP/P001559/1.
Recently I was given the chance to attend the 40th anniversary of the Language and Computation (LAC) group at The University of Essex. As an Essex alumni I was invited to present my work with CASS on Financial Narrative Processing (FNP) part of the ESRC funded project . Slides are available online here.
The event celebrates 40 years of the Language and Computation (LAC) group: an interdisciplinary group created to foster interaction between researchers working on Computational Linguistics within the University of Essex.
There were 16 talks by Essex University alumnus and connections including Yorick Wilks, Patrick Hanks, Stephen Pulman and Anne de Roeck. http://lac.essex.ac.uk/2016-computationallinguistics40
The two day workshop started with Doug Arnold from the Department of Language and Linguistics at Essex. He started by presenting the history and the beginning of the LAC group which started with the arrival of Yorick Wilks in the late 70s and others from Language and Linguistics, this includes Stephen Pulman, Mike Bray, Ray Turner and Anne de Roeck. According to Doug the introduction of the cognitive studies center and the Eurotra project in the 80s led to the introduction of the Computational Linguistics MA paving the way towards the emergence of Language and Computation. Something I always wondered about.
The workshop referred to the beginning of some of the most influential conferences and associations in computational linguistics such as CoLing, EACL and ESSLLI. It also showed the influence of the world events around that period and the struggle researchers and academics had to go through, especially during the cold war and the many university crises around the UK during the 80s and the 90s. Having finished my PhD in 2012 it never crossed my mind how difficult it would have been for researchers and academics to progress under such intriguing situations during that time.
Doug went on to point out how the introduction of the World Wide Web in the mid 90s and the development of technology and computers helped to rapidly advance and reshape the field. This helped in closing the gap between Computation and Linguistics and the problem of field identity between Computational Linguists coming from a Computing or Linguistics background. We now live surrounded by rapid technologies and solid networks infrastructure which makes communications and data processing a problem no more. I was astonished when Stephen Pulman mentioned how they used to wait a few days for the only machine in the department to compile a few lines-of-code of LISP.
The presence of Big Data processing in 2010 and the rapid need for resourcing, crowd-sourcing and interpreting big data added more challenges but interesting opportunities to computational linguists. Something I very much agree with considering the vast amount of data available online these days.
Doug ended his talk by pointing out that in general Computational Linguistics is a difficult field; computational linguists are expected to be experts in many areas, concluding that training computational linguists is deemed to be a challenging and difficult task. As a computational linguist this rings a bell. For example, and as someone from a computing background, I find it difficult to understand how part of speech taggers work without being versed in the grammatical aspect of the language of study.
Doug’s talk was followed by compelling and very informative talks from Yorick Wilks, Mike Rosner and Patrick Hanks.
Yorick opened with “Linguistics is still an interesting topic” narrating his experience in moving from Linguistics towards Computing and the challenge imposed by the UK system compared to other countries such as France, Russia and Italy where Chomsky had little influence. This reminded me of Peter Norivg’s response to Chomsky’s criticism of empirical theory where he said and I quote: “I think Chomsky is wrong to push the needle so far towards theory over facts”.
In his talk, Yorick referred to Lancaster University and the remarkable work by Geoffrey Leech and the build up of the CLAWS tagger, which was one of the earliest statistical taggers to ever reach the USA.
“What is meaning?” was Patrick Hanks talk’s opening and went into discussing word ambiguity saying: “most words are hopelessly ambiguous!”. Patrick briefly discussed the ‘double helix’ rule system or the Theory of Norms and Exploitations (TNE), which enables creative use of language when speakers and writers make new meanings, while at the same time relying on a core of shared conventions for mutual understanding. His work on pattern and phraseologies is of great interest in an attempt to answer the ”why this perfectly valid English sentence fits in a single pattern?” question.
This was followed by interesting talks from ‘Essexians’ working in different universities and firms across the globe. This included recent work on Computational Linguistics (CL), Natural Language Processing (NLP) and Machine Learning (ML). One of those was a collaboration work between Essex University and Signal– a startup company in London.
The event closed with more socialising, drinks and dinner at a Nepalese restaurant in Colchester, courtesy of the LAC group.
In general I found the event very interesting, well organised and rich in terms of historical evidences on the beginning of Language and Computation. It was also of great interest to know about current work and state-of-the-art in CL, NLP and ML presented by the event attendances.
I would very much like to thank The Language and Computation group at Essex Universities for the invitation and their time and effort organising this wonderful event.
Senior Research Associate
CASS, Lancaster University
The BBC’s multilingual NewsHACK event was run on the 15th and 16th of March as an opportunity for teams of language technology researchers to work with multilingual data from the BBC’s connected studio. The theme was ‘multilingual journalism: tools for future news’, and teams were encouraged to bring some existing language technologies to apply to problems in this area. Nine teams attended from various news and research organisations. Lancaster University sent two teams with funding from CASS, CorCenCC, DSI, and UCREL: team ‘1’ consisting of Paul, Scott and Hugo, and team ‘A’ comprising Matt, Mahmoud, Andrew and Steve.
The brief from the newsHACK team suggested two possible directions: to provide a tool for the BBC’s journalist staff, or to create an audience-facing utility. To support us, the BBC provided access to a variety of APIs, but the Lancaster ‘A’ team were most interested to discover that something we’d thought would be available wasn’t — there is no service mapping news stories to their counterparts in other languages. We decided to remedy that.
The BBC is a major content creator, perhaps one of the largest multilingual media organisations in the world. This presents a great opportunity. Certain events are likely to be covered in every language the BBC publishes in, providing ‘translations’ of the news which are not merely literal translations at the word, sentence or paragraph level, but full-fledged contextual translations which identify the culturally appropriate ways to convey the same information. Linking these articles together could help the BBC create a deeply interesting multilingual resource for exploring questions about language, culture and journalism.
Interesting, but how do we make this into a tool for the BBC? Our idea was to take these linked articles directly to the users. Say you have a friend who would prefer to read the news in their native tongue — one different to your own — how would you share a story with them? Existing approaches seem to involve either using an external search engine (But then how do you know the results are what you intend to share, not speaking the target language?) or to use machine translation to offer your friend a barely-readable version of the exact article you have read. We came up with an idea that keeps content curation within the BBC and provides readers with easy-access to the existing high-quality translations being made by professional writers: a simple drop-down menu for articles which allows a user to ‘Read about this in…’ any of the BBC’s languages.
To implement this, in two days, required a bit of creative engineering. We wanted to connect articles based on their content, but we didn’t have tools to extract and compare features in all the BBC’s languages. Instead, we translated small amounts of text — article summaries and a few other pieces of information — into English, which has some of the best NLP tool support (and was the only language all of our team spoke). Then we could use powerful existing solutions to named entity recognition and part-of-speech tagging to extract informative features from articles, and compare them using a few tricks from record linkage literature. Of course, a lack of training data (and time to construct it!) meant that we couldn’t machine-learn our way to perfection for weighting these features, so a ‘human learning’ process was involved in manually tweaking the weights and thresholds until we got some nice-looking links between articles in different languages.
Data is only part of the battle, though. We needed a dazzling front-end to impress the judges. We used a number of off-the-shelf web frameworks to quickly develop a prototype, drawing upon the BBC’s design to create something that could conceivably be worked into a reader’s workflow: users enter a URL at the top and are shown results from all languages in a single dashboard, from which they can read or link to the original articles or their identified translations.
Here we have retrieved a similar article in Arabic, as well as two only-vaguely-similar ones in Portuguese and Spanish (the number indicates a percentage similarity). The original article text is reproduced, along with a translated English summary.
The judges were impressed — perhaps as much with our pun-filled presentation as our core concept — and our contribution, the spontaneously-titled ‘Super Mega Linkatron 5000’ was joint winner in the category of best audience-facing tool.
The BBC’s commitment to opening up their resources to outsiders seems to have paid off with a crop of high-quality concepts from all the competitors, and we’d like to thank them for the opportunity to attend (as well as the pastries!).
The code and presentation for the team ‘A’ entry is available via github at https://github.com/StephenWattam/LU-Newshack and images from Lancaster’s visit can be seen at https://flic.kr/s/aHskwHcpNH . Some of the team have also written their own blog posts on the subject: here’s Matt’s and Steve’s.
Team ‘1’ based their work around the BBC Reality Check service. This was part of the BBC News coverage of the 2015 UK general election and published news items on twitter and contributed to TV and radio news as well. For example, in May 2015 when a politician claimed that the number of GPs has declined under the coalition government, BBC Reality Check produced a summary of data obtained from a variety of sources to enable the audience to make up their own mind about this claim. Reality Check is continuing in 2016 with a similar service for the EU referendum, providing, for example, a check on how many new EU regulations there are every year (1,269 rather than the 2,500 claimed by Boris Johnson!!). After consulting with the BBC technology producer and journalist attending the newsHACK, Team ‘1’ realised that this current Reality Check service could only serve its purpose for English news stories, so set about making a new ‘BBC Multilingual Reality Check’ service to support journalists in their search for suitable sources. Having a multilingual system is really important for the EU referendum and other international news topics due to the potential sources being written in languages other than English.
In order to bridge related stories across different languages, we adopted the UCREL Semantic Analysis System (USAS) developed at Lancaster over the last 26 years. The system automatically assigns semantic fields (concepts or coarse-grained senses) to each word or phrase in a given text, and we reasoned that the frequency profile of these concepts would be similar for related stories even in different languages e.g. the semantic profile could help distinguish between news stories about finance or education or health. Using the APIs that the BBC newsHACK team provided, we gathered stories in English, Spanish and Chinese (the native languages spoken by team ‘1’). Each story was then processed through the USAS tagger and a frequency profile was generated. Using a cosine distance measure, we ranked related stories across languages. Although we only used the BBC multilingual news stories during the newsHACK event, it could be extended to ingest text from other sources e.g. UK Parliamentary Hansard and manifestos, proceedings of the European parliament and archives of speeches from politicians (before they are removed from political party websites).
The screenshot below shows our analysis focussed on some main topics of the day: UK and Catalonia referendums, economics, Donald Trump, and refugees. Journalists can click on news stories in the system and show related articles in the other languages, ranked by our distance measure (shown here in red).
Team ‘1’s Multilingual Reality Check system would not only allow fact checking such as the number of refugees and migrants over time entering the EU, but also allow journalists to observe different portrayals of the news about refugees and migrants in different countries.
There is great delight that the Trinity Lancaster Corpus is providing so much interesting data that can be used to enhance communicative competences in the classroom. From Corpus to Classroom 1 described some of these findings. But how exactly do we go about ‘translating’ this for classroom use so that it can be used by busy teachers with high pressured curricula to get through? How can we be sure we enhance rather than problematize the communicative feature we want to highlight?
Although the Corpus data comes from a spoken test, we want to use it to illustrate wider pragmatic features of communication. The data fascinates students who are entranced to see what their fellow learners do, but how does it help their learning? The first step is to send the research outputs to an experienced classroom materials author to see what they suggest.
Here’s how our materials writer, Jeanne Perrett, went about this challenging task:
As soon as I saw the research outputs from TLC, I knew that this was something really special; proper, data driven learning on how to be a more successful speaker. I could also see that the corpus scripts, as they were, might look very alien and quirky to most teachers and students. Speaking and listening texts in coursebooks don’t usually include sounds of hesitation, people repeating themselves, people self-correcting or even asking ‘rising intonation’ questions. But all of those things are a big part of how we actually communicate so I wanted to use the original scripts as much as possible. I also thought that learners would be encouraged by seeing that you don’t have to speak in perfectly grammatical sentences, that you can hesitate and you can make some mistakes but still be communicating well.
Trinity College London commissioned me to write a series of short worksheets, each one dealing with one of the main research findings from the Corpus, and intended for use in the classroom to help students prepare for GESE and ISE exams at a B1 or B2 level.
I started each time with extracts from the original scripts from the data. Where I thought that the candidates’ mistakes would hinder the learner’s comprehension (unfinished sentences for example), I edited them slightly (e.g. with punctuation). But these scripts were not there for comprehension exercises; they were there to show students something that they might never have been taught before.
For example, sounds of hesitation: we all know how annoying it is to listen to someone (native and non-native speakers) continually erm-ing and er-ing in their speech and the data showed that candidates were hesitating too much. But we rarely, if ever, teach our students that it is in fact okay and indeed natural to hesitate while we are thinking of what we want to say and how we want to say it. What they need to know is that, like the more successful candidates in the data, there are other words and phrases that we can use instead of erm and er. So one of the worksheets shows how we can use hedging phrases such as ‘well..’ or ‘like..’ or ‘okay…’ or ‘I mean..’ or ‘you know…’.
The importance of taking responsibility for a conversation was another feature to emerge from the data and again, I felt that these corpus findings were very freeing for students; that taking responsibility doesn’t, of course, mean that you have to speak all the time but that you also have to create opportunities for the other person to speak and that there are specific ways in which you can do that such as making active listening sounds (ah, right, yeah), asking questions, making short comments and suggestions.
Then there is the whole matter of how you ask questions. The corpus findings show that there is far less confusion in a conversation when properly formed questions are used. When someone says ‘You like going to the mountains?’ the question is not as clear as when they say ‘Do you like going to the mountains?’ This might seem obvious but pointing it out, showing that less checking of what has been asked is needed when questions are direct ones, is, I think very helpful to students. It might also be a consolation-all those years of grammar exercises really were worth it! ‘Do you know how to ask a direct question? ‘Yes, I do!’
These worksheets are intended for EFL exam candidates but the more I work on them, the more I think that the Corpus findings could have a far wider reach. How you make sure you have understood what someone is saying, how you can be a supportive listener, how you can make yourself clear, even if you want to be clear about being uncertain; these are all communication skills which everyone needs in any language.
At the end of February, a team of CASS researchers attended the Presentation of the Queen’s Anniversary Prizes for Further and Higher Education, held at Buckingham Palace. The CASS team officially received the award from their Royal Highnesses, The Prince of Wales and the Duchess of Cornwall on 25th February 2016.
Back in November, it was announced that CASS received the esteemed Queen’s Anniversary Prize for its work in “computer analysis of world languages in print, speech, and online.” The Queen’s Anniversary Prizes are awarded every two years to universities and colleges who submit work judged to show excellence, innovation, impact, and benefit for the institution itself, and for the people and society generally in the wider world.
10 of us were selected to attend the ceremony itself, including the Chancellor, Vice-Chancellor, our Centre Director Tony McEnery, and three students. Buckingham Palace sent strict instructions about dress code and the possession of electronic devices, and we were well-read on royal etiquette by the time the big day arrived. I think all of us were a little nervous about what the day would have in store, but we met bright-eyed and bushy-tailed at 9:30am, and took a taxi to Green Park. We entered through the front gates into Buckingham Palace, and looked back at the crowd of adoring fans on the other side of the railings.
We showed our entry cards, and found ourselves being ushered across the courtyard and into the Palace itself. We dropped off our coats and bags, and then went up the grand staircase into the Ballroom where the ceremony was held. We began to relax as the Equerry told us what would be happening throughout the ceremony, and the Countess of Wessex’s String orchestra provided excellent music throughout the event. The score ranged from Handel, right through to John Lennon’s ‘Imagine’, and even a James Bond theme.
As the ceremony started, Vice-Chancellor Mark Smith and CASS Centre Director Tony McEnery passed through the guests, along with representatives from other universities and colleges, and then proceeded to form a line to receive the award. Chancellor Alan Milburn was seated at the front of the Ballroom, along with Anne, Princess Royal. Whilst receiving the award on behalf of CASS, The Prince of Wales asked the Vice-Chancellor about our work, and was fascinated to discover what we have undertaken in the past 40 years. After a brief chat about our work, Mark Smith and Tony McEnery were presented with the Queen’s Anniversary Prize medal and certificate that will be displayed in the John Welch Room in University House.
After the ceremony, we filed through into the Picture Gallery for the reception. Over the course of the next 60-90 minutes, guests were free to mingle and network with each other whilst canapés were served. Dignitaries passed through and spoke to the visitors; Anne, Princess Royal, had a keen interest in the impact of our work on dictionary-making, and I must admit that Tony McEnery was excellent at giving a summary of what corpus research entails. He outlined how it is used in modern-day dictionary building, and discussed some of the historical texts that we now have access to.
The Duchess of Cornwall also visited our group over the course of the event, and made a point of speaking to both Gill Smith and Rosie Knight about the practical applications of their research. They discussed extensively why corpus research is such a useful method in the social sciences, and spoke of their personal connection to the research centre.
Having the opportunity to promote and discuss our research with royalty was a true honour, and I think it is fantastic to see the work of CASS recognised in this unique and special way.
Historically, in British English at least, if you didn’t know someone’s preferred gender it was considered grammatically correct to use he to refer to them, even if they might be female. Based on the justification that ‘the masculine includes the feminine’, this means that all of the following would be considered fine examples of English usage:
- The driver in front is swerving like he is drunk.
- A scientist is a fountain of knowledge; he should be respected.
- Any student wishing to answer a question should raise his hand.
- Everyone should consider his own family when choosing how to vote.
When you picture the people referred to in these scenarios, were any of them women? Or, to put it another way, were any of them any identity other than ‘male’? Evidence from psychological experiments has shown that the pronoun he (in all its forms) evokes a male image in the mind. Its use as a ‘generic’ pronoun, in contrast to what grammarians of old seemed to think, actually makes it harder to read and process sentences with stereotypically feminine referents (i.e. A childminder must wash his hands before feeding the children.).
So if you don’t want to go around assuming that all the world is male by default, what do you do? Luckily, there is a solution to this problem: if you don’t know a person’s gender identity, you can use the pronoun they to refer to them. There may be a mental screech of brakes here for those of you who were taught that they is a plural pronoun, but actually, it’s more versatile than that. Try using they for he in all of the sentences above. When thinking about the scientist or the driver, was there suddenly more than one? No. Indeed, singular they has been shown not to interfere with mental processing in the way that generic he does. I used it in the first sentence of this post and I’ll bet you didn’t even notice it. (Go on. Check.)
For those of you still not convinced, the use of singular they is widespread in spoken and written English. It’s highly likely that you use the form yourself without even thinking about it. In British Pronoun Use, Prescription and Processing (Palgrave 2014) an analysis of this type of pronouns demonstrates that singular they is ubiquitous in British English. If you still need more convincing, here’s a link to an extremely favourable review of that study just published in Language and Society.
Looking back over the academic year as it draws to a close, one of the highlights for us here at CASS was the one-day seminar we hosted in January on Perspectives on Chinese: Talks in Honour of Richard Xiao. This event celebrated the contributions to linguistics of CASS co-investigator Dr. Richard Zhonghua Xiao, on the occasion of both his retirement in October 2014 (and simultaneous taking-up of an honorary position with the University!), and the completion of the two funded research projects which Richard has led under the aegis of CASS.
The speakers included present and former collaborators with Richard – some (including myself) from here at Lancaster, others from around the world – as well as other eminent scholars working in the areas that Richard has made his own: Chinese corpus linguistics (especially, but not only, comparative work), and the allied area of the methodologies that Richard’s work has both utilised and promulgated.
In the first presentation, Prof. Hongyin Tao of UCLA took a classic observation of corpus-based studies – the existence, and frequent occurrence, of highly predictable strings or structures, pointed out a little-noticed aspect of these highly-predictable elements. They often involve lacunae, or null elements, where some key component of the meaning is simply left unstated and assumed. An example of this is the English expression under the influence, where “the influence of what?” is often implicit, but understood to be drugs/alcohol. It was pointed out that collocation patterns may identify the null elements, but that a simplistic application of collocation analysis may fail to yield useful results for expressions containing null elements. Finally, an extension of the analysis to yinxiang, the Chinese equivalent of influence, showed much the same tendencies – including, crucially, the importance of null elements – at work.
The following presentation came from Prof. Gu Yueguo of the Chinese Academy of Social Sciences. Gu is well-known in the field of corpus linguistics for his many projects over the years to develop not just new corpora, but also new types of corpus resources – for example, his exciting development in recent years of novel types of ontology. His presentation at the seminar was very much in this tradition, arguing for a novel type of multimodal corpus for use in the study of child language acquisition.
At this point in proceedings, I was deeply honoured to give my own presentation. One of Richard’s recently-concluded projects involved the application of Douglas Biber’s method of Multidimensional Analysis to translational English as the “Third Code”. In my talk, I presented methodological work which, together with Xianyao Hu, I have recently undertaken to assist this kind of analysis by embedding tools for the MD approach in CQPweb. A shorter version of this talk was subsequently presented at the ICAME conference in Trier at the end of May.
Prof. Xu Hai of Guangdong University of Foreign Studies gave a presentation on the study of the study of Learner Chinese, an issue which was prominent among Richard’s concerns as director of the Lancaster University Confucius Institute. As noted above, Richard has led a project funded by the British Academy, looking at the acquisition of Mandarin Chinese as a foreign language; as a partner on that project, Xu’s presentation of a preliminary report on the Guangwai Lancaster Chinese Learner Corpus was timely indeed. This new learner corpus – already in excess of a million words in size, and consisting of a roughly 60-40 split between written and spoken materials – follows the tradition of the best learner corpora for English by sampling learners with many different national backgrounds, but also, interestingly, includes some longitudinal data. Once complete, the value of this resource for the study of L2 Chinese interlanguage will be incalculable.
The next presentation was another from colleagues of Richard here at Lancaster: Dr. Paul Rayson and Dr. Scott Piao gave a talk on the extension of the UCREL Semantic Analysis System (USAS) to Chinese. This has been accomplished by means of mapping the vast semantic lexicon originally created for English across to Chinese, initially by automatic matching, and secondarily by manual editing. Scott and Paul, with other colleagues including CASS’s Carmen Dayrell, went on to present this work – along with work on other languages – at the prestigious NAACL HLT 2015 conference, in whose proceedings a write-up has been published.
Prof. Jiajin Xu (Beijing Foreign Studies University) then made a presentation on corpus construction for Chinese. This area has, of, course, been a major locus of activity by Richard over the years: his Lancaster Corpus of Mandarin Chinese (LCMC), a Mandarin match for the Brown corpus family, is one of the best openly-available linguistic resources for that language, and his ZJU Corpus of Translational Chinese (ZCTC) was a key contribution of his research on translation in Chinese . Xu’s talk presented a range of current work building on that foundation, especially the ToRCH (“Texts of Recent Chinese”) family of corpora – a planned Brown-family-style diachronic sequence of snapshot corpora in Chinese from BFSU, starting with the ToRCH2009 edition. Xu rounded out the talk with some case studies of applications for ToRCH, looking first at recent lexical change in Chinese by comparing ToRCH2009 and LCMC, and then at features of translated language in Chinese by comparing ToRCH2009 and ZCTC.
The last presentation of the day was from Dr. Vittorio Tantucci, who has recently completed his PhD at the department of Linguistics and English Language at Lancaster, and who specialises in a number of issues in cognitive linguistic analysis including intersubjectivity and evidentiality. His talk addressed specifically the Mandarin evidential marker 过 guo, and the path it took from a verb meaning ‘to get through, to pass by’ to becoming a verbal grammatical element. He argued that this exemplified a path for an evidential marker to originate from a traversative structure – a phenomenon not noted on the literature on this kind of grammaticalisation, which focuses on two other paths of development, from verbal constructions conveying a result or a completion. Vittorio’s work is extremely valuable, not only in its own right but as a demonstration of the role that corpus-based analysis, and cross-linguistic evidence, has to play on linguistic theory. Given Richard’s own work on the grammar and semantics of aspect in Chinese, a celebration of Richard’s career would not have been complete without an illustration of how this trend in current linguistics continues to develop.
All in all, the event was a magnificent tribute to Richard and his highly productive research career, and a potent reminder of how diverse his contributions to the field have actually been, and of their far-reaching impact among practitioners of Chinese corpus linguistics. The large and lively audience certainly seemed to agree with our assessment!
Our deep thanks go out to all the invited speakers, especially those who travelled long distances to attend – our speaker roster stretched from California in the west, to China in the east.
