Abstract :
Distributed Information Retrieval (DIR) has been suggested to offer a prospective solution to a number of issues concerning information retrieval in the WWW. On the other hand, previous studies have indicated that centralized approaches offer the best solution for optimal quality of result (i.e. effectiveness). In this paper, we revisit those claims and investigate if and under which conditions can DIR offer a new paradigm for both efficient and effective information retrieval.
