TAC Tracks

A TAC cycle consists of a set tracks -- areas of focus in which particular NLP tasks are defined. Task definitions and guidelines for a particular year are given in the individual track home pages for that year (see the table of track home pages below). Data for each track in the current TAC cycle (including test data and evaluation results) are available only to registered participants in the current cycle. Data from past TACs are available to non-participants on the web page for Past Data.

Mailing Lists

Each track has a mailing list. The primary purpose of the mailing list is to discuss the details of the track's tasks in the current TAC cycle. However, a track mailing list also serves as a place to discuss general methodological issues related to the track's NLP focus. TAC track mailing lists are open to all; you need not participate in TAC to join a list. Most lists do require that you become a member of the list before you can send a message to it. Instructions for joining track mailing lists are given in the individual track home pages.
