Knowledge Base Population (KBP) 2013

Overview

The goal of TAC Knowledge Base Population (KBP) is 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. The reference KB for 2013 is based on a snapshot of English Wikipedia from October 2008 and is the same reference KB that has been used in TAC KBP since 2009. Each node in the reference KB corresponds to a Wikipedia page for a person (PER), organization (ORG), or geopolitical entity (GPE) and consists of predefined attributes (a.k.a "slots") derived from Wikipedia infoboxes. Unstructured text from the Wikipedia page is also available (as "wiki_text") in the reference KB.

KBP can be decomposed into two complementary tracks: entity linking, in which entity mentions must be aligned with entities in the reference KB or new entities discovered in the document collection; and slot filling, which involves finding predefined attributes about target entities in unstructured text. A third major KBP track is Cold Start KBP, which combines entity linking and slot filling to populate an empty KB using the predefined schema from slot filling. Three additional tracks -- temporal slot filling, sentiment slot filling, and Spanish slot filling -- enrich the KB by adding temporal constraints to slot filling relations, augmenting the KB with relations involving sentiment between KBP entities, and filling in the KB using information from both English and Spanish documents. Finally, the slot filler validation track focuses on the refinement of output from slot filling systems by either combining information from multiple slot filling systems, or applying more intensive linguistic processing to validate candidate slot fillers.

Tracks

  • Entity Linking
    The entity linking task is to link entity mentions in a document collection to entities in a reference KB, or to new named entities discovered in the document collection.

  • English Slot Filling
    The slot filling task is to search a document collection to fill in values for predefined slots (attributes) for a given entity in a reference KB.

  • Temporal Slot Filling
    The goal of temporal slot filling is to augment a KB with temporal constraints on slot filling relations.

  • Cross-lingual Spanish Slot Filling
    The Spanish slot filling track extends English slot filling to the cross-lingual paradigm, in which English and Spanish documents are used to populate an English reference KB.

  • Sentiment Slot Filling
    The overall goal of the Sentiment Slot Filling track is to assess the quality of detectors for scoped and attributed sentiment.

  • Slot Filler Validation
    The Slot Filler Validation track focuses on the refinement of output from slot filling systems by either combining information from multiple slot filling systems, or applying more intensive linguistic processing to validate individual candidate slot fillers.
    Track coordinator: Hoa Dang (hoa.dang@nist.gov)

  • Cold Start KBP
    The Cold Start track integrates entity linking and slot filling to build a knowledge base from scratch.
