Association index architecture for information brokers
Bernd Wondergem, P. van Bommel, Th.P. van der Weide · 1998
Information Discovery (ID) is the synthesis of Information Retrieval (IR) and Information Filtering (IF). In ID, broker agents act as intermediaries between user agents and source agents. Information about user interests and documents in sources can be modeled by 2-level hypermedia representations. These representations allow navigational mechanisms which have proven their effectiveness in IR applications. Broker agents should thus combine two 2-level hypermedia representations to obtain an overall information structure necessary for the synthesis of IR and IF. For this, we propose the so called Association Index Architecture (AIA) which consists of two 2-level hypermedia representations which are connected through a third level which is coined the association index. The AIA thus forms a 3-level hypermedia representation. Broker agents can perform actions in the AIA to implement their IR and IF related tasks. The AIA is shown to be a general symbolic architecture for combining knowled...
