TAC 2012 Workshop
TAC KBP 2012
Overview
TAC 2012 focuses on Knowledge Base Population (KBP). The goal of Knowledge Base Population is to promote research in automated systems that discover information about named entities as found in a large corpus and incorporate this information into a knowledge base. TAC 2012 fields tasks in three areas, all aimed at improving the ability to automatically populate knowledge bases from text:
- Entity-Linking: Given a name (of a Person, Organization, or Geopolitical Entity) and a document containing that name, determine the KB node for the named entity, adding a new node for the entity if it is not already in the KB. The reference KB is derived from English Wikipedia, while source documents come from a variety of languages, including English, Chinese, and Spanish.
- Slot-Filling: Given a named entity and a pre-defined set of attributes ("slots") for the entity type, augment a KB node for that entity by extracting all new learnable slot values for the entity as found in a large corpus of documents. The reference KB is derived from English Wikipedia, while source documents come from English and Spanish. A diagnostic task, Slot Filler Validation, will be to determine whether a candidate filler in a document is a correct slot-filler for a given entity.
- Cold Start Knowledge Base Population: Given a KB schema with an empty knowledge base, build the KB from scratch by mining a large text collection.
