If you are interested in participating in the HCIR Challenge, please let me know as soon as possible–and in any case by April 30th. The New York Times and the LDC are graciously providing access to The New York Times Annotated Corpus for free (waiving the usual $300 fee), but we need to let the LDC know who will be participating. Hope to see lots of you presenting your systems at HCIR 2010!
Also, participants building their systems in Solr can take advantage of the scripts that Tommy Chheng has prepared. Of course, you are welcome to use your own system. Commercial software companies are especially encouraged to show off their HCIR wares!
