Text Analysis Conference Knowledge Base Population (TAC KBP)
The Text Analysis Conference (TAC) was a series of evaluations and workshops organized to promote research in natural language processing and related applications by providing a large test collection, common evaluation procedures, and a forum for organizations to share their results. The goal of TAC KBP was to develop and evaluate technologies for building and populating knowledge bases (KBs) about named entities from unstructured text. KBP systems must either populate an existing reference KB, or else build a KB from scratch.
LDC supported TAC KBP through the development of source data and annotations and by contributing to task development activities and discussions each year. Read more about the project on LDC's Papers page.
