We invite papers on various topics concerning the use of Web resources for corpus research and NLP applications, including (but not limited to) the following:

* linguistic Web crawler technology and Web corpus collection projects
* applications of Web-derived corpora and other kinds of Web data
* how far does the “easy way” get you? (using search engines, or Google's n-gram lists; we are particularly interested in a critical discussion of the usefulness and limitations of such approaches)
* methods and tools for “cleaning” Web pages to turn them into a corpus
* automatic linguistic annotation of Web data: tokenisation, POS tagging, lemmatisation, semantic tagging, etc. (established tools often perform very poorly on Web data)
* search engine architectures for linguists: bringing linguistics to commercial search engines, or high-performance search technology to linguistics?
* search engine-related topics such as result ranking (e.g. how to identify “typical” uses rather than returning 50 very similar matches on the first page)
* duplicate detection, interactive query refinement, etc.
* reviews and clever uses of search engine APIs (Google, Yahoo, Altavista, and in particular Microsoft's current generous Live Search API)

The workshop will be held on 7 September, 2009, in San Sebastian, preceding SEPLN, the Spanish NLP conference: http://ixa2.si.ehu.es/sepln2009/

We particularly welcome submissions on the use of languages other than English. One of the bottlenecks in corpus linguistic research on a particular language consists in availability of corpora for this language: translation studies for, say, Ukrainian or Vietnamese are limited by the existence of diverse corpora for these languages. The Web gives the opportunity to alleviate this bottleneck, as millions of Ukrainian or Vietnamese texts are available on the Web, but we still do not know many parameters of what is there and how useful it is for translation, language teaching, linguistics research, etc.

SUBMISSION INFORMATION

Authors are invited to submit full papers on original, unpublished work in the topic area of this workshop. Submissions should follow the format of ACL proceedings and should not exceed eight (8) pages, including references. We strongly recommend the use of ACL LaTeX or Microsoft Word style files tailored for this year's conference (http://www.acl-ijcnlp-2009.org/main/authors/stylefiles/).

Submissions are managed via Easy Chair. In order to submit a paper, login at http://www.easychair.org/conferences/?conf=wac5 (or register an account with Easy Chair if you don't have one yet), then click New Submission and fill in the standard fields.
