COMPUTING SYSTEM

PROBLEM TO BE SOLVED: To precisely achieve the extraction of peculiar expressions in katakana (the square form of Japanese syllabary). SOLUTION: A computing system includes a processor, a memory, and an interface, and collects texts in a second language other than Japanese and extracts words being highly probably peculiar expressions from the collected texts, converts extracted peculiar expression candidates in the second language to Japanese character strings by using reading information, collects texts in Japanese and extracts katakana words appearing in the Japanese texts, determines similarities between the Japanese character strings converted from peculiar expression candidate words in the second language and katakana character strings extracted from the Japanese texts, and determines katakana character strings having high similarities to be peculiar expressions.
