    • Wikify! 13 has two components. The first, keyword extraction, decides if a phrase should be linked to Wikipedia. This is based on how often a word or phrase is found to be in the anchor text of some link internal to Wikipedia. The second step is disambiguation. Wikify!, too, is conservative in flagging keywords, so much so that even random disambiguation results in an F1 score of 0.82. Suppose Wikify! is considering linking spot [math]\displaystyle{ s }[/math] to entity γ. Wikipedia’s page describing γ is explicitly referred from other Wikipedia pages. The context of these known citations is compared with the context of [math]\displaystyle{ s }[/math] to decide on a compatibility score. This may be regarded as generalizing SemTag, where known references to γ form part of the metadata of γ. … However, none of these systems attempt collective disambiguation across spots.

Abstract

This paper introduces the use of Wikipedia as a resource for automatic keyword extraction and word sense disambiguation, and shows how this online encyclopedia can be used to achieve state-of-the-art results on both these tasks. The paper also shows how the two methods can be combined into a system able to automatically enrich a text with links to encyclopedic knowledge. Given an input document, the system identifies the important concepts in the text and automatically links these concepts to the corresponding Wikipedia pages. Evaluations of the system show that the automatic annotations are reliable and hardly distinguishable from manual annotations.
