ComRank: Metasearch and Automatic Ranking of XML Retrieval Systems
Woodley, Alan P. & Geva, Shlomo (2005) ComRank: Metasearch and Automatic Ranking of XML Retrieval Systems. In Kunii, Toysiyasu L., Hock Soon, Seah, & Sourin, Alexi (Eds.) International Conference on Cyberworlds, 23-25 November 2005, Singapore.
Different information retrieval (IR) systems often return very diverse results lists for the same query. This is problematic for users since no one IR system works best for every scenario, and it is difficult for the user to know which system will work best a priori. The challenge of metasearch is to merge results lists from several IR systems, with the goal of outperforming each of the constituent systems. This paper presents ComRank, a metasearch system that discriminates in favour of results that (1) originate by consensus amongst several systems; (2) are highly ranked in their original systems and (3) originate from the better performing systems. Importantly, ComRank determines the ‘better’ performing systems without the need for human judgements. Rather, it uses an automatic assessment process that ranks systems by their pseudo-relevance, as derived from highly ranked results in ComRank’s list. We apply our methods to the INEX Collection, which is an unexplored domain for these methods, and show that they are comparable to or better than baseline alternatives.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
