CW2I: Community data indexing for complex query processing

Abstract

The increasing popularity of Community Web Management Systems (CWMSs) calls for tailor-made data management approaches for them. Still, existing CWMSs have mostly focused on simple similarity-based queries; they do not provide a framework for the efficient processing of more complex queries over community web data. In this paper, we propose a two-way indexing scheme that facilitates efficient and scalable retrieval and complex query processing with community data. A thorough experimental comparison, based on real-world data and practical queries, illustrates the advantages of our scheme compared to other approaches for community web data management. Besides, our double-indexing scheme provides an attractive solution to the storage problem as well. © 2010 Springer-Verlag.
