Ganjisaffar, Yasser, Javanmardi, Sara and Lopes, Cristina (2009): Leveraging crowdsourcing heuristics to improve search in Wikipedia. In: Proceedings of the 2009 International Symposium on Wikis 2009. p. 27. http://www.wikisym.org/ws2009/procfiles/p126-ganjisaffar.pdf

Wikipedia articles are usually accompanied with history pages, categories and talk pages. The meta-data available in these pages can be analyzed to gain a better understanding of the content and quality of the articles. We analyze the quality of search results of the current major Web search engines (Google, Yahoo! and Live) in Wikipedia. We discuss how the rich meta-data available in wiki pages can be used to provide better search results in Wikipedia. We investigate the effect of incorporating the extent of review of an article into ranking of search results. The extent of review is measured by the number of distinct editors who have contributed to the articles and is extracted by processing Wikipedia's history pages. Our experimental results show that re-ranking search results of the three major Web search engines, using the review feature, improves quality of their rankings for Wikipedia-specific searches.
