RTE5: Registration opened until May 31

Since 2004, RTE Challenges have promoted research in textual entailment recognition as a task that captures major semantic inference needs across many natural language processing applications, such as Question Answering (QA), Information Retrieval (IR), Information Extraction (IE), and multi-document summarization.
Over the years the encouraging progress, in terms of both the number of researchers involved and results achieved, has spurred the community to further investigate the phenomena involved by adding innovations to the challenge every year and moving it toward more realistic scenarios.

Capitalizing on the favorable response obtained so far, the RTE Organizing Committee is glad to launch the Fifth Recognizing Textual Entailment Challenge, proposed for the second year as a track of the Text Analysis Conference (TAC). Organizations interested in participating in the RTE5 Challenge are invited to submit a track registration form by May 31, at the TAC 2009 website.
