OwWwL and Agent- Nation are Java- language computer programs that act together, quickly scanning Internet databases for relevant information, then organizing the infor- mation into a format suited to the user. OwWwL is a search- engine program that, like other such programs, includes a “spider” subprogram that “crawls” the Web, indexing content. AgentNation is a collaborative-computing program that is used by OwWwL to perform its tasks in a collaborative manner; that is, OwWwL and AgentNation can be run simultaneously on multiple computers to perform large-scale searches. The biggest difference between OwWwL and other search-engine programs is that as the OwWwL spider subprogram performs a search on a given topic, it begins to search for related information. OwWwL includes a personal-search-assistant subprogram that with the help of AgentNation, searches other Internet search engines simultaneously.
