To make it possible to register also an unregistered word mixedly including HIRAGANA (cursive form of Japanese syllabary), KANJI (Chinese character), etc., in a dictionary by providing the text data retrieving device with a means for judging whether a key word is a word registered in a dictionary file or not and a means for registering a key word in the dictionary file as a word when the key word is not registered.
A morpheme analyzing means 3 executes morpheme analysis for text data inputted by a dictionary file 4. A retrieving means 8 retrieves a word coincident with a key word received by a key word receiving means 7 within words divided by the means 3 and outputs a retrieved result. A judging means judges whether an inputted key word is a word not registered in the file 4 or not, and in the case of a word not registered in the file 4, a registering means 9 registers the key word in the file 4. In addition, the means 9 registers a key word received by the means 7 more than the prescribed number of times as a word.
