TAC 2011 Knowledge Base Population (KBP2011) Track
Question Answering and Information Extraction have been studied over the past
decade; however evaluation has generally been limited to isolated targets or
small scopes (i.e., single documents). The Knowledge Base Population (KBP) Track
at TAC 2011 will explore extraction of information about entities with reference to an
external knowledge source. Using basic schema for persons, organizations, and
locations, nodes in an ontology must be created and populated using unstructured
information found in text. A collection of
Wikipedia Infoboxes will
serve as a rudimentary initial knowledge representation.
June 10: 63 teams have registered for KBP2011 so far.
May 26: annotation guidelines are updated.
May 15: Final task definition is available.
