TAC Knowledge Base Population Track
At TAC 2009 and TAC 2010 the Knowledge Base Population (KBP) Track explored extraction of information about entities with reference to an external knowledge source. Please visit the official KBP 2009 site and the official KBP 2010 site for more information.
Linguistic Data Consortium develops linguistic resources -- corpora, tools and specifications -- to support the TAC KBP evaluation. Guidelines and specifications for the 2009 and 2010 tasks can be found on the Specifications page. A table summarizing TAC KBP data releases made to KBP program participants to date can be found on the Data page.
