TAC KBP English Temporal Slot Filling - Comprehensive Training and Evaluation Data 2011 and 2013 was developed by the Linguistic Data Consortium (LDC) and contains training and evaluation data produced in support of the TAC KBP English Temporal Slot Filling tasks in 2011 and 2013.

Text Analysis Conference (TAC) is a series of workshops organized by the National Institute of Standards and Technology (NIST). TAC was developed to encourage research in natural language processing and related applications by providing a large test collection, common evaluation procedures, and a forum for researchers to share their results. Through its various evaluations, the Knowledge Base Population (KBP) track of TAC encourages the development of systems that can match entities mentioned in natural texts with those appearing in a knowledge base and extract novel information about entities from a document collection and add it to a new or existing knowledge base.

The goal of the Temporal Slot Filling task was to identify and capture temporal information in text indicating when a given relation between a slot filling query entity and filler held true. This built upon the technology developed for regular Slot Filling which involved mining information about entities from text. For more information about Temporal Slot Filling, refer to the 2013 track home page.


This release contains all evaluation and training data developed in support of TAC KBP Temporal Slot Filling 2011 and 2013, the two years the track was conducted. This includes queries, the manual runs produced by LDC annotators, and the final rounds of assessment results.
