Title: Information retrieving system
Inventor: KAWASHITA MITSURU
IPC: G06F17/30
Filed: 1989-07-10
Abstract: PURPOSE:To efficiently retrieve information having similar names by referring to a dictionary to obtain the representative word of words constituting a name specified by an operator. CONSTITUTION:A representative word conversion part 8 divides a name inputted from a name registering part 7 into several words while referring to words registered in a word storage part 3 and obtains the representative word ID of a representative word corresponding to respective words. Namely, the name is registered 6 by referring to the dictionary, dividing the name to be registered into words, obtaining the representative word corresponding to the divided words and forming and storing a list indicating the correspondence between the name and the representative word. At the time of executing retrieval, the name including the same representative word as the representative word of words constituting the name specified by the operator is retrieved from the list. Consequently, a similar name corresponding to the name specified by the operator can be efficiently obtained.
