The Workshop on Aggregated seeks to define the research problems for aggregated search results, and to build a community of researchers working in this emerging area. Aggregated search addresses the issues of how to select and rank resources, how to present them to a user in such a way that information can be found efficiently and effectively. The aim of the workshop was to encourage discussion and the exchange of ideas about the directions for aggregated search. The workshop presented prototype systems, user studies of existing systems, as well as papers about component technologies.
