Facetedpedia: Dynamic Generation of Query-Dependent Faceted Interfaces for Wikipedia - scientific work related to Wikipedia quality published in 2010, written by Chengkai Li, Ning Yan, Senjuti Basu Roy, Lekhendro Lisham and Gautam Das.

Overview

This paper proposes Facetedpedia, a faceted retrieval system for information discovery and exploration in Wikipedia. Given the set of Wikipedia articles resulting from a keyword query, Facetedpedia generates a faceted interface for navigating the result articles. Compared with other faceted retrieval systems, Facetedpedia is fully automatic and dynamic in both facet generation and hierarchy construction, and the facets are based on the rich semantic information from Wikipedia. The essence of approach is to build upon the collaborative vocabulary in Wikipedia, more specifically the intensive internal structures (hyperlinks) and folksonomy (category system). Given the sheer size and complexity of this corpus, the space of possible choices of faceted interfaces is prohibitively large. Authors propose metrics for ranking individual facet hierarchies by user's navigational cost, and metrics for ranking interfaces (each with k facets) by both their average pairwise similarities and average navigational costs. Authors thus develop faceted interface discovery algorithms that optimize the ranking metrics. Authors experimental evaluation and user study verify the effectiveness of the system.
