Problem-oriented information retrieval decision support systems

Decision Support Systems(DSS) are man-machine interaction systems, which support the decision-makers to solve the unstructured and semi-structured decisions. This paper advances that the function of problem-oriented information retrieval DSS can meet the needs of enterprise's top management effectively in comparison with other information retrieval functions, in accordance with the features of supporting information for decision. An architecture of this system is presented, which modifies a problem put forward or recognized by the user into a problem recognized by the computer, forming retrieval tactics and searching the data the user needs. Designed and developed according to the architecture of this system, a prototype system is introduced, which is CF Economic Environment Information Retrieval DSS.
