Description

  The present invention relates to an information processing apparatus having a function of converting input kana characters into kanji and the like.

  Patent Document 1 discloses a technique for converting a kana character input by a user into a kana-kanji mixed sentence using one word dictionary data. In an apparatus that performs kana-kanji conversion processing, such as a word processor, word dictionary data in which words of 100,000 words or more are registered is generally used.

JP-A-11-25087

  By the way, when extracting Kanji characters corresponding to the Kana characters input by the user from the word dictionary data, the input Kana characters are compared with the word readings in the word dictionary data, and the Kanji characters corresponding to the matching readings are converted. Display as a candidate. Such comparison processing is normally performed by comparing data stored in a main storage unit such as a RAM (Random Access Memory) in the apparatus. In the above-mentioned Patent Document 1, since one word dictionary data is used, when comparing the input kana characters and the reading of the words in the word dictionary data, all the words in the dictionary data are expanded on the main storage unit. There is a need.

  In recent years, embedded devices such as in-vehicle devices are sometimes provided with a kana-kanji conversion processing function because of the need to input names and sentences. However, in such an embedded device, computer resources are limited, and it is often impossible to mount a large-capacity main storage unit. Therefore, there are many cases where word dictionary data with a large number of words, such as those used in word processors, cannot be expanded on the main memory, and unavoidably, the word dictionary data can be expanded on the main memory. By reducing the number of words, Kana-Kanji conversion processing may be realized.

  However, by reducing the number of words in the word dictionary data, there may occur a situation in which the kanji corresponding to the input kana character does not exist in the word dictionary data, and conversion candidates are not found. The efficiency of Kana-Kanji conversion may be reduced, such as the need to re-input a Kana character corresponding to, and the convenience of the user may be impaired.

  Further, even if a large-capacity main storage unit is provided in the embedded device, the embedded device often cannot provide an arithmetic device with high processing capability from the viewpoint of power consumption, cost, and the like. Therefore, if the arithmetic unit in the embedded device compares all input kana characters with the readings of each of the 100,000 words expanded on the main storage unit, the processing time for kana-kanji conversion is long. Or the processing load due to Kana-Kanji conversion may cause other processing to be realized.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the capacity of dictionary data developed on the main storage unit and to improve the processing speed of kana character conversion.

  In order to solve the above-described problem, the information processing apparatus of the present invention performs kana-kanji conversion processing using dictionary data composed of words corresponding to a genre determined according to a user operation.

  For example, the first aspect of the present invention is a plurality of dictionary data used for information processing kana-kanji conversion, which is composed of words belonging to a specific genre, and a plurality of dictionaries in which at least some registered words are different. Dictionary data storage means for storing data in association with the dictionary ID for identifying each dictionary data, and information indicating the genre of the word registered in the dictionary data corresponding to the dictionary ID in association with the dictionary ID The genre table storage means for storing the genre table for storing the genre table, the accepting means for accepting the operation from the user, the genre table based on the genre determined according to the operation from the user, The dictionary ID of the registered dictionary data is specified, and the dictionary data corresponding to the specified dictionary ID is stored in the dictionary data Dictionary data acquisition means acquired from the means, and character conversion means for executing kana-kanji conversion processing according to the kana characters input from the user via the reception means using the dictionary data acquired by the dictionary data acquisition means. Provided is an information processing apparatus including the information processing apparatus.

  In addition, the second aspect of the present invention relates to a word data storage unit that stores a corresponding word for each word ID that identifies each of a plurality of information processing words, and corresponds to the word ID in association with the word ID. A genre table holding unit that holds a genre table that stores one or more pieces of information indicating the genre of a word to be received, a receiving unit that receives an operation from the user, The word acquisition means for referring to and specifying the word ID of the word corresponding to the genre, acquiring the word corresponding to the specified word ID from the word data storage means, and a plurality of words acquired by the word acquisition means The dictionary data used in Kana-Kanji conversion is created, and the created dictionary data is used by the user via the accepting means. To provide an information processing apparatus, characterized in that it comprises a character conversion means for performing a kana-kanji conversion process according to the kana characters.

  According to the information processing apparatus of the present invention, it is possible to reduce the capacity of dictionary data developed on the main storage unit and to improve the processing speed of kana character conversion.

  First, a first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating an example of the configuration of the information processing apparatus 10 according to the first embodiment. The information processing apparatus 10 includes a dictionary data storage unit 11, a genre table storage unit 12, a reception unit 13, a dictionary data acquisition unit 14, a character conversion unit 15, and a service table storage unit 16. The information processing device 10 is, for example, a portable information processing terminal such as a mobile phone, a PDA (Personal Data Assistance), or a notebook general-purpose computer, or an in-vehicle device such as a car audio or a navigation device.

  In the dictionary data storage unit 11, for example, a plurality of dictionary data 110 are stored in advance as shown in FIG. Each dictionary data 110 stores a dictionary ID 111 for identifying the dictionary data 110, a word 113, and a reading 112 of the word 113.

  At least some of the words stored in each dictionary data 110 are different from the words stored in other dictionary data 110. Each dictionary data 110 is composed of words belonging to a genre different from other dictionary data 110. Here, the genre is a scene where the word is used, a name of a set to which the meaning of the word belongs, and the like. Some words belong to a plurality of genres, and such words are stored in a plurality of different dictionary data 110.

  Dictionary data includes, for example, dictionary data consisting only of facility names, dictionary data consisting only of convenience store names, dictionary data consisting only of song names, dictionary data consisting only of singer names, songs Dictionary data composed only of the names of the albums that are recorded, dictionary data composed only of words used for e-mail, and the like. For example, dictionary data consisting only of facility names includes all words registered in dictionary data consisting only of convenience store names, and dictionary data consisting only of album names Includes a part of words registered in dictionary data composed only of song names.

  Thus, by registering different words in each of the plurality of dictionary data 110, the data amount of each dictionary data 110 can be made smaller than dictionary data in which all words are registered. Each dictionary data 110 may be configured such that only words that are not stored in other dictionary data 110 are stored in each dictionary data 110. Thereby, the data amount of each dictionary data 110 can further be reduced. Since the data structure of each dictionary data 110 is the same as the structure of general dictionary data, detailed description is omitted.

  In the genre table storage unit 12, for example, a genre table 120 as shown in FIG. 3 is stored in advance. The genre table 120 stores, for each dictionary ID 121, a genre 122 to which a word registered in dictionary data corresponding to the dictionary ID 121 belongs.

  For example, a service table 160 as shown in FIG. 4 is stored in the service table storage unit 16 in advance. The service table 160 stores one or more genres 162 to which words input in the menu belong, for each menu ID 161 for identifying a menu for specifying a service provided by the information processing apparatus 10.

  For example, when a navigation function is realized by the information processing apparatus 10, a menu ID corresponding to a menu for registering point information by text input in a state in which an icon indicating a convenience store is designated, includes “convenience store” as a genre. "Is associated. In addition, a “facility name” is associated as a genre with a menu ID corresponding to a menu for registering point information by text input in a state where an icon indicating a facility is not designated.

  The data in the dictionary data storage unit 11, the genre table storage unit 12, and the service table storage unit 16 is stored in an HDD (Hard Disk Drive) or a flash ROM (Read Only Memory) provided in the information processing apparatus 10. It is stored in the auxiliary storage unit.

  The accepting unit 13 accepts user operation information via the input device 20 such as a touch panel attached to the display device 21 of the information processing device 10, identifies a menu specified by the user, and corresponds to the identified menu. The execution of the function is instructed to a processing unit in the information processing apparatus 10 that realizes the function.

  Further, when the menu specified by the user is a menu that requires text input (in the text input mode), the reception unit 13 notifies the dictionary data acquisition unit 14 of the menu ID of the menu specified by the user. . In addition, the reception unit 13 sends text data input from the user via the input device 20 to the character conversion unit 15 in the text input mode.

  In the text input mode, as a method of inputting text data to the information processing apparatus 10, a kana character is specified by touching a button displayed on the display device 21 for each character using the input device 20 such as a touch panel. A method of designating kana characters by handwriting by tracing the touch panel on the display device 21, a method of designating kana characters by voice recognition, and the like can be used.

  When the menu ID is notified from the reception unit 13, the dictionary data acquisition unit 14 refers to the service table 160 in the service table storage unit 16 and identifies the genre associated with the menu ID. Then, the dictionary data acquisition unit 14 refers to the genre table 120 in the genre table storage unit 12 and extracts a dictionary ID associated with the specified genre. Then, the dictionary data acquisition unit 14 acquires dictionary data corresponding to the extracted dictionary ID from the dictionary data storage unit 11, and sends the acquired dictionary data to the character conversion unit 15.

  When there are a plurality of genres corresponding to the menu ID notified from the reception unit 13, the dictionary data acquisition unit 14 acquires all the dictionary data associated with each genre from the dictionary data storage unit 11. It is sent to the character conversion unit 15.

  The character conversion unit 15 performs kana-kanji conversion processing according to the text data received from the reception unit 13 using the dictionary data received from the dictionary data acquisition unit 14, and displays character conversion candidates corresponding to the text data on the display device 21. To display. In the present embodiment, the kana-kanji conversion process includes not only a process of converting an input kana character into a kana-kanji mixed sentence, but also a process of converting the input kana character into katakana, alphabet, or symbol.

  When a plurality of dictionary data are received from the dictionary data acquisition unit 14, the character conversion unit 15 combines the plurality of dictionaries by collecting the same words registered in each of the plurality of dictionary data. Data is merged, and kana-kanji conversion is executed using the merged dictionary data.

  Further, the character conversion unit 15 stores the dictionary data received from the dictionary data acquisition unit 14 or the dictionary data obtained by merging a plurality of dictionary data received from the dictionary data acquisition unit 14 into a RAM (Random Access) in the information processing apparatus 10. The Kana-Kanji conversion process is executed using the developed dictionary data.

  Here, if the character conversion unit 15 performs kana-kanji conversion processing using dictionary data in which all words are registered, depending on the input kana characters, the input kana characters and 100,000 words are used. In some cases, all word readings in the dictionary data are all compared. In this case, in an embedded device provided with an arithmetic device having a low processing capability, the processing time for Kana-Kanji conversion may become long, or processing to be realized may be delayed due to the processing load due to Kana-Kanji conversion.

  On the other hand, since the information processing apparatus 10 according to the present embodiment uses dictionary data composed of words belonging to the genre of the menu being selected by the user, the size of the dictionary data used for kana-kanji conversion processing is reduced. Can do. Thereby, the processing load of Kana-Kanji conversion can be kept low, and the processing speed of Kana-Kanji conversion can be improved.

  Moreover, in this embodiment, all the words registered in the dictionary data composed only of the name of the convenience store are included in the dictionary data composed only of the name of the facility, and are composed only of the name of the convenience store. The amount of dictionary data to be performed is smaller than that of dictionary data composed only of facility names. Thus, the size of the corresponding dictionary data can be reduced as the genre is limited in the number of words used. Therefore, kana-kanji conversion can be executed more efficiently for genres where the number of words used is limited.

  FIG. 5 is a flowchart illustrating an example of the operation of the information processing apparatus 10 according to the first embodiment. For example, the information processing apparatus 10 starts the operation shown in this flowchart at a predetermined timing such as when the power is turned on.
