Focused Search in Books and Wikipedia: Categories, Links and Relevance Feedback - scientific work related to Wikipedia quality published in 2009, written by Marijn Koolen, Rianne Kaptein and Jaap Kamps.

Overview

In this paper authors describe participation in INEX 2009 in the Ad Hoc Track, the Book Track, and the Entity Ranking Track. In the Ad Hoc track authors investigate focused link evidence, using only links from retrieved sections. The new collection is not only annotated with Wikipedia categories, but also with YAGO/WordNet categories. Authors explore how authors can use both types of category information, in the Ad Hoc Track as well as in the Entity Ranking Track. Results in the Ad Hoc Track show Wikipedia categories are more effective than WordNet categories, and Wikipedia categories in combination with relevance feed-back lead to the best results. Preliminary results of the Book Track show full-text retrieval is effective for high early precision. Relevance feedback further increases early precision. Authors findings for the Entity Ranking Track are in direct opposition of Ad Hoc findings, namely, that the WordNet categories are more effective than the Wikipedia categories. This marks an interesting difference between ad hoc search and entity ranking.
