Abstract

Abstract When character codes and character patterns coexist in the retrieval character string and/or the retrieval objective data, they are standardized into character patterns, and a character string matching with or similar to the retrieval character string is retrieved from the retrieval objective data. A character code included in the retrieval character string and/or the retrieval objective data is converted into a character pattern by referring to a prepared character pattern dictionary, and by pattern matching between two character patterns, a character string matching with or similar to the retrieval character string is picked up from the retrieval objective data and produced as the result of retrieval.
