ACL Wiki for Computational Linguistics - Report for 2007 Peter Turney peter.turney@nrc-cnrc.gc.ca The ACL has created a new wiki specifically for Computational Linguistics, at http://aclweb.org/aclwiki. The purpose of this wiki is to facilitate the sharing of information on all aspects of Computational Linguistics. The ACL Wiki was created to fill a role that Wikipedia cannot fill. The wiki includes links to Computational Linguistics blogs, conferences, competitions, people, organizations, course descriptions, corpora, datasets, and introductory articles on topics such as Computational Lexicology, Computational Semantics, and Word Sense Disambiguation. The ACL Wiki was initiated by Steven Bird, Ali Hakim, Dragomir Radev, and Peter Turney. On October 18th, 2006, MediaWiki software was installed on the ACL web server and the ACL Wiki began running. The new wiki was announced on the ACL mailing list on October 30th, 2006. This report was written when the wiki had been open to the public for about half a year. At that time, there were 1,755 pages in the wiki database. This figure includes minimal pages that have relatively low content, but there were at least 100 high-content pages. In this half-year period, there have been more than 100,000 page views and more than 2,000 page edits, an average of more than 500 views and 10 edits per day. Only registered users can edit pages and there are about 260 registered users. Registration requires only a valid email address. Although it has only been running for half a year, it is clear that the ACL Wiki has already attracted the support and involvement of the Computational Linguistics community.
