Using Wikipedia Categories for Ad Hoc Search

Using Wikipedia Categories for Ad Hoc Search - scientific work related to Wikipedia quality published in 2009, written by Rianne Kaptein, Marijn Koolen and Jaap Kamps.

Overview

In this paper authors explore the use of category information for ad hoc retrieval in Wikipedia. Authors show that techniques for entity ranking exploiting this category information can also be applied to ad hoc topics and lead to significant improvements. Automatically assigned target categories are good surrogates for manually assigned categories, which perform only slightly better.
