CONCEPT RETRIEVING SYSTEM

摘要

PURPOSE:To improve the efficiency of the title system by inputting a (partial) character string indicating a concept to be retrieved and a (partial) character string indicating its high-order concept. CONSTITUTION:The titled system has a means for inputting plural character strings indicating the concept to be extracted and its high-order concept independently of orders, a means for deciding that respective input character strings are connected to matched concepts with the same comprehensive relation a means for extracting the least signigicant concept among concepts having the same comprehesive relation and coincident with the input character string. Since a concept can be retrieved by inputting the (partial) character string of the concept to be extracted by a user and the (partial) character string of its high-order concept, the extraction of unnecessary character stings can be reduced as compared with an ordinary character string extraction inputting only the (partial) character string of an extracted character string.
