The Knowledge Base Population (KBP) is an evaluation track of the Text Analysis Conference (TAC) workshop series organized by the National Institute of Standards and Technology (NIST). The KBP evaluation includes two tasks that target information extraction and question answering technologies: Entity Linking and Slot Filling. Cross-lingual Entity Linking and Temporal Slot Filling were introduced in 2011 to evaluate systems’ abilities to recognize multilingual and temporal information. Linguistic Data Consortium (LDC) supports the TAC KBP evaluation by producing linguistic resources including data, annotations, system assessment, tools and specifications. This paper describes the resource creation efforts in support of KBP 2011, with an emphasis on annotation and assessment procedures and methodologies.
