Vast sources of information, such as the Internet are difficult to browse and/or search through. Existing tools can be sometimes frustrating for many people. So far a number of techniques have been proposed to deliver user-oriented solutions. The problem re-surfaces however within a ubiquitous computing paradigm. Aside from a possible delay in response time, their are additional drawbacks with respect to mobile devices such as: Bandwidth size, storage(what type of costs do you mean) and performance costs and client UI size. In this paper we introduce three search and browsing features: fulltext search, collaborative filtering and multifaceted browsing, all of which can be enriched with semantic and community information. We present two of the aforementioned techniques implemented in our interface for digital libraries -DigiMe.
