basic requirements to keep in mind for an ideal agent-based web information retrieval system in ubiquitous environments
This paper describes UWIRS (acronym of U biquitous W eb I nformation R etrieval S olution), an agent-based W eb I nformation R etrieval ( WIR ) solution designed taking into account the unique features of the W orld W ide W eb ( WWW ) and the limitations of existing WIR solutions, to explain basic functional requirements to keep in mind for an ideal WIR system in ubiquitous environments. In UWIRS , agents cooperate in order to retrieve personalized information, considering user needs, goals, preferences and contextual features. UWIRS's agents are responsible for: interpreting user input and adding adaptation information by means of a query enrichment process; identifying and selecting the appropriate data sources taking into consideration the Profile Set (composed of User, Device and Information-Provider Profiles); executing query routing and the information retrieval process; integrating and filtering the retrieved results; and lastly, coherent presentation of quality and relevant ubiquitous information (anytime, anywhere and anyhow) that satisfies the user's particular information needs and constraints associated to his/her access device. Overall, the main challenge resides on: location, retrieval, integration and presentation of information from the WWW , quickly and accurately, to satisfy a user's singular information needs.
