TCAR at TAC-KBP 2009

The TCAR team developed multiple systems in just a matter of weeks for both participating in the TAC-KBP evaluation under the entity linking and the slot filling paradigms. TCAR's entity linking processes consisted of one that leveraged information retrieval and a separate that sought to appeal to extraction-based techniques. With regard to slot filling, since the TAC evaluation was touted as a task that would appeal to both the question answering and content extraction communities, we opted to build two systems where the first made use of our question answering system and the latter exploited relation-finding from a number of our content extraction systems. We here provide detailed descriptions of our systems and their performance at TAC-KBP.
