To be targeted.

  The morpheme analysis unit 211 analyzes the first information stored in the first information storage unit 201 by morpheme analysis, and extracts (generates) a plurality of second information based on the analysis result. The morpheme analysis unit 211 performs morpheme analysis processing on the first information distributed by BCMCS and stored in the first information storage unit 201. The morpheme analysis unit 211 extracts (generates) second information from the analysis result in the first information. Morphological analysis is a function that divides a sentence into a plurality of elements such as nouns, particles, and verbs and discriminates them. Here, the second information includes not only nouns and particles that have been subjected to morphological analysis, but also character strings and documents that combine these.

  The category classification unit 213 classifies the second information generated by the morpheme analysis unit 211 into predetermined categories in a plurality of categories. The second information classified into the predetermined category by the category classification unit 213 is stored in association with the predetermined category classified in the second information storage unit 203.

  Here, when new first information is received by the communication unit 200, the morphological analysis unit 211 and the category classification unit 213 extract (generate) second information based on the received new first information, and Sort into categories. The second information stored in the second information storage unit 203 is updated to newly extracted (generated) second information.

  Further, when the second information stored in the second information storage unit 203 is updated to new second information in a state where the predetermined second information is displayed on the LCD display unit 21, input candidate extraction described later is performed. The unit 215 updates the input candidate based on the new updated second information in the second information storage unit 203. Then, the second information as the input candidate displayed on the LCD display unit 21 is updated to new second information.

  The input unit 219 receives the predetermined second information selected by the selection unit 217 as a character input. For example, when a predetermined key (input confirmation key) on the operation unit 101 is pressed, the input unit 219 accepts character input for the second information as the input candidate selected by the selection unit 217. The second information as the input candidate accepted by the input unit 219 is input as a character string constituting a predetermined sentence. That is, when the input of the predetermined second information selected by the input unit 219 is accepted, the second information for which the input is accepted is inserted into the sentence being created.

  The operation unit 101 includes an operation key group 11. The operation unit 101 executes a function assigned to a predetermined key by pressing a predetermined key constituting the operation key group 11. In addition, the operation unit 101 accepts character input from the outside while the mail function or the like is activated, and assists the user in creating a predetermined document. Specifically, when inputting characters, the operation unit 101 selects a predetermined input candidate from a plurality of input candidates (second information) displayed on the LCD display unit 21 and inputs input keys (for example, circular keys). When the key is assigned to 15b, the input of the selected character string can be confirmed.

  The LCD display unit 21 is configured to display various information. The LCD display unit 21 is configured to be able to display a character string extracted as an input candidate by the input candidate extraction unit 215. Specifically, the LCD display unit 21 is configured to be able to display the second information stored in the second information storage unit 203 extracted as an input candidate by the input candidate extraction unit 215. The LCD display unit 21 displays in a recognizable manner that the predetermined second information is selected when the cursor 400 overlaps the predetermined second information. When an input of the selected predetermined second information is received, the LCD display unit 21 displays a document in which the second information for which the input has been received is inserted.
