TAC KBP Evaluation Source Corpora 2016-2017

<h3>Introduction</h3><br>
<p>TAC KBP Evaluation Source Corpora 2016-2017 was developed by the Linguistic Data Consortium (LDC) and contains the 180,003 Chinese, English and Spanish source documents used in support of all TAC KBP evaluation tracks conducted in <a href="https://tac.nist.gov/2016/KBP/index.html">2016</a> and <a href="https://tac.nist.gov/2017/index.html">2017</a>.</p><br>
<p>Text Analysis Conference (<a href="https://tac.nist.gov/">TAC</a>) is a series of workshops organized by the National Institute of Standards and Technology (<a href="https://www.nist.gov/">NIST</a>). 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.</p><br>
