This paper describes our approach to the 2012 Text Analysis Conference (TAC) Knowledge Base Population (KBP) entity linking track. For this task, we turn to a state-of-the-art system for entity linking in microblog posts. Compared to the little context microblog posts provide, the documents in the TAC KBP track provide context of greater length and of a less noisy nature. In this paper, we adapt the entity linking system for microblog posts to the KBP task by extending it with approaches that ex-plicitly rely on the query’s context. We show that incorporating novel features that leverage the context on the entity-level can lead to im-proved performance in the TAC KBP task. 1
