Abstract
The problem of document management in an Office Information System in view of supporting the decision process by a set of users with different knowledge, capabilities and requirements is considered. User profiles are used to improve the retrieval properties and a control system is outlined to automatically update the utility information used by the searching strategies. user requirements are modeled in Dynamic User Profiles in order to maintain accurate knowledge of the most promising approach to document search, of the interest fields, and of the favourite output format. An example of DUP use is provided adopting a flexible query specification to take advantage of database selection, retrieval via keyword, or full text scanning in a multi-strategy query processing approach. Actual queries are redefined by extracting the aspects suitable for each strategyI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
