Abstract

PURPOSE:To effectively retrieve a synonym by decomposing a synonym input which is retrieved and registered, by a synonym analyzing device, coupling them again to a retrieval conditional expression of an OR condition,and executing an information retrieval. CONSTITUTION:An information retrieving system 2 inputs a key value for executing a retrieval from a key designating device 1, and sends the inputted key value to a synonym relation retrieving device 3. This device 3 retrieves whether a synonym relation corresponding to the key value which is sent from the device 1 is registered in a synonym file 6 or not, if it is registered, its synonym relation is read and sent to a synonym relation analyzing device 4. Subsequently, the device 4 analyzes the synonym relation which is sent from the device 3, decomposes it to each synonym, and thereafter, couples again all synonyms to a retrieval conditional expression of an OR condition, and sends it to an information retrieving device 5. The device 5 retrieves a data base 7 by the retrieval conditional expression which is sent from the device 5, sends its result to a retrieval result output device 8, and outputs a retrieval result.
