In the new era of wireless, mobile connectivity the possibilities of anything, anytime, anywhere access are becoming a reality. In order to deliver services and content to users in a variety of contexts, content adaptation strategies need to be developed and assessed. In this paper we present an approach to performance evaluation and capacity planning, based on a high-level system description f...

We consider the problem of efficiently finding the top-k answers for join queries over web-accessible databases. Classical algorithms for finding top-k answers use branch-and-bound techniques to avoid computing scores of all candidates in identifying the top-k answers. To be able to apply such techniques, it is critical to efficiently compute (lower and upper) bounds and expected scores of cand...

This paper analyzes the suitability of fuzzy clustering methods for the discovery of relevant document relationships, motivated by the need for enhanced relevancebased navigation of Web-accessible resources. The performance evaluation of a modified Fuzzy c-Means algorithm is carried out, and a comparison with a traditional hard clustering technique is presented. Clustering precision and recall ...
