SIGLEX is the Special Interest Group on the Lexicon, providing an umbrella
for research interests on lexical issues ranging from lexicography and the
use of online dictionaries to computational lexical semantics. SIGLEX is
also the umbrella organization for Senseval/Semeval - the evaluation
exercise for systems for the semantic analysis of text.

The following ACL members are currently serving as SIGLEX officers:

President: Rada Mihalcea, University of North Texas
Secretary: Ted Pedersen, University of Minnesota, Duluth

Executive Board:
Francesca Bertagna, Istituto di Linguistica Computazionale (ILC-CNR)

One of the main events for 2007 was the Semeval (former Senseval) exercise
for the evaluation of systems for the semantic analysis of text. The
evaluation took place in Spring 2007, and the workshop is scheduled to take
place on June 23-24 2007, in conjunction with the ACL conference in Prague.
The co-chairs are Richard Wicentowski (Swarthmore College), Lluis Marquez
(Universitat Politecnica de Catalunya), and Eneko Agirre (University of Basque
Country). This has been a highly successful event, with 18 different tasks
(selected out of the 25 submitted), more than 100 participating teams, and
more than 125 systems. This represents a significant increase compared to the
14 tasks and 55 teams participating in Senseval-3. More information about Semeval
is available from the event webpage http://nlp.cs.swarthmore.edu/semeval/.
