Description

  The present invention relates to a dictionary creation system, a dictionary server, a portable terminal, a dictionary creation method, and a dictionary creation program.

  2. Description of the Related Art In recent years, forms of text creation such as email transmission and reception and Web search using a mobile terminal have become normal. In order to implement such a function on a mobile terminal, the mobile terminal has a built-in kana-kanji conversion dictionary for converting kana characters into kanji. However, since the built-in Kana-Kanji conversion dictionary generally contains only the words used, it does not contain terms that are biased by the user, such as dedicated terms for specific fields.

  In addition, since the kana-kanji conversion dictionary built into the mobile terminal cannot normally be changed, it cannot be used for new words that are used after the date of sale of the mobile terminal. In addition, words that are not recorded may be provided by a DL dictionary (Download dictionary), but words that an individual wants to use are not necessarily recorded. Therefore, there is a demand for a function that can add words that an individual wants to use freely to a dictionary.

In order to solve such a problem, Japanese Patent Application Laid-Open No. 2002-183127 disclosed in Patent Document 1 “User dictionary generation registration system, dictionary server, terminal, user dictionary generation method, user dictionary registration method, and information recording medium” The e-mail transmitted from the terminal is intercepted by the dictionary server, and it is analyzed whether or not a word or phrase not registered in the terminal dictionary is included. Has been proposed in which a dictionary server is transmitted to a terminal and additionally registered in the dictionary of the terminal.

  The kana-kanji conversion unit 13 converts a kana character input by the user 1 for text creation into a kanji character selected by the user 1 by displaying a list of kanji conversion candidates obtained by referring to the kana-kanji conversion dictionary 15. Then, it is converted into a normal text sentence mixed with Kana-Kanji. The dictionary registration unit 14 registers the dictionary data 20 </ b> A returned from the dictionary server 20 by adding it to the kana-kanji conversion dictionary 15 built in the mobile terminal 10.

  On the other hand, the dictionary server 20 includes at least a voice data reception unit 21, a dictionary data transmission unit 22, a voice recognition unit 23, a morpheme analysis unit 24, a dictionary data creation unit 25, and a dictionary database 26. The voice data receiving unit 21 receives the voice data 10 A for dictionary data creation request transmitted from the mobile terminal 10 via the network 30 and delivers it to the voice recognition unit 23. The dictionary data transmission unit 22 returns the dictionary data 20A created by the dictionary data creation unit 25, which will be described later, via the network 30 to the mobile terminal 10 that has transmitted the corresponding voice data 10A. is there.

  The voice recognition unit 23 extracts voice data including a term to be registered in the kana-kanji conversion dictionary 15 from the voice data 10A from the voice data receiving unit 21, and performs a recognition process on the voice data to thereby extract kana characters. Is converted to a kana text sentence, and is taken over by the morpheme analysis unit 24. The morpheme analysis unit 24 performs morphological analysis on the kana text sentence from the speech recognition unit 23 to perform word / term division for decomposing the kana text sentence into units of terms registered in the kana-kanji conversion dictionary 15. . The dictionary data creation unit 25 extracts kanji and part-of-speech information corresponding to the kana character string divided into words and terms by the morphological analysis unit 24 while referring to the dictionary database 26, and is a dictionary in a format that can be registered in the dictionary. It is created as data 20A, and the created dictionary data 20A is sent to the dictionary data transmission unit 22.

  Here, the dictionary database 26 is used in various fields including not only general terms as described in ordinary Japanese language dictionaries but also special technical terms used in specific fields. It is a database that registers existing terms, including recent new words. Note that the dictionary server 20 can make an inquiry to another server via the network 30 when information related to the corresponding term is not registered in the dictionary database 26.

  Next, an example of a dictionary creation method in the dictionary creation system 100 shown in FIG. 2 will be described using the flowchart of FIG. FIG. 3 is a flowchart showing an example of the dictionary creation method of the dictionary creation system 100 according to the present invention. FIG. 3 (A) shows the processing contents on the mobile terminal 10 side, and FIG. The processing contents on the dictionary server 20 side are shown.

  First, when the user 1 of the mobile terminal 10 finds a term to be additionally registered in the kana-kanji conversion dictionary 15 built in the mobile terminal 10, the user 1 uses the operation unit of the mobile terminal 10 to register the dictionary. After setting to the voice input mode, a voice 1A including a dictionary registration term is input from a microphone or the like (step S11). The input voice 1 </ b> A is received by the voice input unit 11 and sent to the voice data transmission unit 12. The voice data transmitting unit 12 creates voice data 10A by converting the sent voice 1A into a voice data format for requesting dictionary data creation (step S12). Next, the created voice data 10A is transmitted to the dictionary server 20 via the network 30 (step S13). When the transmission is completed, the transmission is interrupted until the corresponding dictionary data 20A is returned from the dictionary server 20.

  On the other hand, in the dictionary server 20, when the voice data receiving unit 21 receives dictionary data creation request voice data 10A from the portable terminal 10 via the network 30 (step S21), the received voice data 10A is voice-recognized. Sent to part 23. The speech recognition unit 23 recognizes the sent speech data 10A by speech and converts it into a kana text sentence (step S22). The converted kana text sentence is morphologically analyzed by the morpheme analyzing unit 24 and divided into words / terms into terms registered in the kana-kanji conversion dictionary 15 built in the mobile terminal 10 (step S23).

  With respect to each kana character string of the kana text sentence divided into words and terms, the dictionary data creation unit 25 performs a process of searching for the corresponding kanji and part of speech information while referring to the dictionary database 26, and finally. Then, dictionary data 20A in a format that can be registered in the kana-kanji conversion dictionary 15 built in the mobile terminal 10 is created (step S24).

  The dictionary data 20A created by the dictionary data creation unit 25 is transmitted to the requesting mobile terminal 10 that has transmitted the voice data 10A corresponding to the dictionary data 20A in the dictionary data transmission unit 22 via the network 30. (Step S25).

  When the portable terminal 10 receives the dictionary data 20A from the dictionary server 20 via the network 30 (step S14), the suspended state is canceled and the dictionary registration unit 14 is activated. The dictionary registration unit 14 sequentially extracts terms in the dictionary registration unit included in the received dictionary data 20A, and checks whether or not the term is registered in the built-in kana-kanji conversion dictionary 15 (step S15). If it has already been registered (YES in step S15), the process proceeds to step S17 to process the next term in the dictionary data 20A without performing duplicate registration, but the term that has not yet been registered. If it is (NO in step S15), it is registered in the kana-kanji conversion dictionary 15 as a new term (step S16).

  Next, the dictionary registration unit 14 of the mobile terminal 10 checks whether or not all the terms included in the dictionary data 20A received from the dictionary server 20 have been processed (step S17), and still remains. (NO in step S17), the process returns to step S15 and proceeds to the process for the next term. If all the terms have been processed (YES in step S17), the dictionary registration process is terminated.

  As described above, in the present invention, the voice 1A including the term to be used on the mobile terminal 10 side is transmitted to the dictionary server 20 as the voice data 10A for requesting dictionary data creation, and the dictionary server 20 By returning the dictionary data 20A converted into a format that can be used by the mobile terminal 10, the terminology that is desired to be used as the kana-kanji conversion dictionary built in the mobile terminal 10 is automatically registered. If necessary, it is possible to dynamically obtain conversion kanji necessary for creating a kana-kanji mixed text sentence as needed.

  Further, in the present invention, since the request for creating the term to be registered is transmitted to the dictionary server using the original voice data for the dictionary data creation request separately from the email, it takes time to create the email. In addition, there will be no delay in email transfer.

  In the present invention, the dictionary server is a mechanism for returning the terms registered in the Kana-Kanji conversion dictionary to the requesting mobile terminal, and the dictionary server needs to constantly grasp the dictionary registration status of each mobile terminal. On the other hand, on the mobile terminal side, terms and new words that the user uses only in a specific field can be easily added and registered in the mobile terminal of the user.
