Tag grid: Supporting collaborative and fuzzy multidimensional queries of tagged datasets

In recent years, a noticable portion of the data on the Web is organized by tags, forming the phenomenon of tag clouds. In this paper, we present a query facility called tag grid to support fuzzy search and queries of both tags and data items alike. By combinating methods of Online Analytic Processing from multidimensional databases and collaborative filtering from information retrieval, tag grid enable users to search for interesting data items by navigating and discovering interesting tags.
