Abstract

The World Wide Web grows at alarming rates, making information retrieval an increasingly difficult process. Traditional search methods based on search-engines usually flood the users with an overwhelming number of URLs. If a user wants to stay up-to-date on some issue and he repeatedly queries the above search engines, (s)he will be repeatedly flooded with (almost) the same set of URLs, out of which only a small percentage will point to new, previously unseen documents. In the first part of this thesis, a resource discovery tool is presented, built on top of traditional search engines and called FIREFLY. FIREFLY registers each user's interests and repeatedly queries several search engines for URLs matching a user's registered interests. FIREFLY keeps track of which URLs have been visited by each user. Thus, when a user invokes FIREFLY, he is presented only with new or "unvisited" URLs. The second part of this thesis, focuses in a specific functionality of FIREFLY implemented especially for monitoring search queries periodically. This tool, called AlertService, aims in helping users to keep track of the information, which they are interested in, among the growing number of web sites, that becomes available on-line. It also operates on top of popular search engines. If new information is found, an electronic mail will be sent to the user, who is interested in.
