PROBLEM TO BE SOLVED: To produce a name key for retrieval/collation, capable of obtaining a high-accuracy collation result from a name character string including a difficult word such as a foreign language or a substitute character.;SOLUTION: A word division means 4 divides the inputted name character string into words by use of a word dictionary, and produces a name word string wherein a word class, semantics and character kind information are imparted to each word. A reading assignment means 5 decides whether the character kind information is the difficult word or a normal word about each word inside the name word string, and acquires/imparts corresponding reading from a reading dictionary of the difficult word to perform conversion into the already reading-assigned name word string. A name key production means 6 extracts an important word from the already reading-assigned name word string by use of an important word extraction table, decides whether the character kind information is the difficult word or the normal word, and outputs a word string wherein only notation of the difficult word among the important words is replaced with the reading as the name key together with the word string wherein the notation of all the important words among the already reading-assigned name word string is just as input for the difficult word.;COPYRIGHT: (C)2007,JPO&INPIT
