PROBLEM TO BE SOLVED: To provide a technique which efficiently specifies the theme of sentences. SOLUTION: In a sentence processing system 10, a sentence inputted by a user is acquired by a sentence acceptance part 26 and is set as a noticed block by an object setting part 28, and a character string analysis part 34 extracts one or more words from the noticed block, and a set of the words is used to update sets of words extracted in the past, and thus a theme specifying part 42 specifies the theme of the sentence. |
