Laying the Groundwork for Knowledge Base Population: Nine Years of Linguistic Resources for TAC KBP.

Knowledge Base Population (KBP) is an evaluation series within the Text Analysis Conference (TAC) evaluation campaign conducted by the National Institute of Standards and Technology (NIST). Over the past nine years TAC KBP evaluations have targeted information extraction technologies for the population of knowledge bases comprised of entities, relations, and events. Linguistic Data Consortium (LDC) has supported TAC KBP since 2009, developing, maintaining, and distributing linguistic resources in three languages for seven distinct evaluation tracks. This paper describes LDC's resource creation efforts for the various KBP tracks, and highlights changes made over the years to support evolving evaluation requirements.
