Abstract: This thesis studies the inconsistency problems in web-based information retrieval. Particularly, we attempt to address the problems of correctness of functions, and reuse of pervasive content. Firstly, we redefine content and propose a novel content consistency model with 4 content consistency classes. We then study 4 cases of inconsistency problems in a?? replica/CDN, web mirrors, web proxies and content TTL/lifetime respectively. Results show that inconsistency can cause unpredictable caching behaviour, performance loss, content presentation errors, etc. Lastly, to solve the consistency problems in web mirrors and P2P, we propose a solution to answer a??where to get the right contenta?? based on a new ownership concept. Protocol extensions have been developed and implemented to support ownership in HTTP/1.1 and Gnutella/0.6.
