Abstract

We study the task of entity linking for Twitter, which tries to associate each mention in a tweet with a corresponding knowledge base entry. Two main challenges of this task are the dearth of information in a single tweet and the rich entity mention variations.

To address these challenges, We propose a collective inference model that simultaneously resolves a set of mentions. Particularly, Our model integrates three kinds of similarities, i.e., mention-entry similarity, entry-entry similarity, and mention-mention similarity, to enrich the context for entity linking, and to address irregular mentions that are not covered by the entity-variation dictionary.

We evaluate our method on a publicly available data set and demonstrate the effectiveness of our method.
