Information retrieval using an Ontological Web-Trading model

One of the biggest problems facing Web-based Information Systems (WIS) is the complexity of the information searching/retrieval processes, especially the information overload, to distinguish between relevant and irrelevant content. In an attempt to solve this problem, a wide range of techniques based on different areas has been developed and applied to WIS. One of these techniques is the information retrieval. In this paper we described an information retrieval mechanism (only for structured data) with a client/server implementation based on the Query-Searching/Recovering-Response (QS/RR) model by means of a trading model, guided and managed by ontologies. This mechanism is part of SOLERES system, an Environmental Management Information System (EMIS).
