ABSTRACT
Wikification is the task to link textual mentions in a document to articles in Wikipedia. It comprises three main steps, namely, mention recognition, candidate generation, and entity linking. For candidate generation, existing methods use hyperlinks in Wikipedia or match a mention of discourse to Wikipedia article titles. They may miss the correct target entity and thus fail to link the mention to Wikipedia. In this paper, we propose to use a mention as a query and Wikipedia own search engine to look for additional candidate articles. Moreover, for entity linking, we introduce new coreference heuristics and apply the incremental liking approach. The conducted experiments show that our proposed method outperforms or achieves competitive results in comparison to some state-of-the-art systems, but is simpler and uses less features.
