Description

  The present invention relates to an electronic dictionary, a dictionary search method, and a program.

Currently, electronic dictionaries that hold the contents of a plurality of dictionaries such as a Japanese-English dictionary, an English-Japanese dictionary, and an English-French dictionary as electronic data and display translations of words, parts of speech, synonyms, example sentences, and the like are widely used.
The electronic dictionary described in Patent Document 1 is based on the selected word as a key when a user arbitrarily selects a word to be further examined from translations and example sentences searched and displayed by a certain type of dictionary. It has a so-called jump function for searching other dictionaries. For example, when a word is selected from an English translation searched using a Japanese-English dictionary, it is possible to jump to an English-Japanese dictionary, an English-French dictionary, or the like.
JP 2007-241683 A

By the way, for example, when searching for French from Japanese using an electronic dictionary equipped with a Japanese-English dictionary, an English-Japanese dictionary, and an English-French dictionary, the electronic dictionary described in Patent Document 1 temporarily translates English from Japanese into the Japanese-English dictionary. There is a problem that it takes time and effort to search and search the English-French dictionary using a jump function using English words as a search result.
Although it is conceivable to install a Japanese-French dictionary in the electronic dictionary, there is a problem that the dictionary data stored in the electronic dictionary becomes enormous.
The present invention has been made in view of the above points, and an object of the present invention is to provide an electronic dictionary, a dictionary search method, and a program capable of providing more dictionary functions with a predetermined dictionary data amount with good operability. Is to provide.

  SUMMARY An advantage of some aspects of the invention is that character input means for inputting character data, a headword, and translation data corresponding to the headword are stored. A dictionary data storage means for storing dictionary data and a character data input by the character input means as a headword, a translation data corresponding to the headword is extracted from dictionary data corresponding to the first dictionary type. Extraction means, and second extraction means for extracting translation data corresponding to the entry word from dictionary data corresponding to the second dictionary type using the translation data extracted by the first extraction means as an entry word. An electronic dictionary comprising display means for displaying the translation data extracted by the second extraction means.

According to another aspect of the present invention, in the electronic dictionary described above, a conversion table storage unit that stores a rule for each set of the first dictionary type and the second dictionary type; An entry word extraction unit that acquires a rule corresponding to a set of one dictionary type and the second dictionary type, and extracts an entry word from translation data extracted by the first extraction unit according to the acquired rule; And the second extraction means extracts translation data from dictionary data corresponding to the second dictionary type using the headword extracted by the headword extraction means.

Further, according to one aspect of the present invention, in the electronic dictionary described above, the second extraction unit uses the extracted translation data as a headword as long as the headword corresponding to the extracted translation data is in the dictionary data. Translation data is repeatedly extracted sequentially from the dictionary data, and the display means displays a list of all translation data extracted by the first extraction means and the second extraction means. The headword corresponding to the translation data is a headword whose translation data, word, and language match.

  According to another aspect of the present invention, the electronic dictionary includes a dictionary type selection unit that selects a dictionary type, and the second extraction unit corresponds to the dictionary type selected by the dictionary type selection unit. Until the data is extracted, the extracted translation data is used as a headword, and the translation data is repeatedly extracted sequentially from the dictionary data. The translation data corresponding to the dictionary type is translation data whose language matches the translation data language of the dictionary type.

  Further, according to one aspect of the present invention, an electronic dictionary storing dictionary data that holds a headword and translation data corresponding to the headword inputs character data; and the electronic dictionary is input Extracting the translation data corresponding to the entry word from the dictionary data corresponding to the first dictionary type, and the electronic dictionary using the extracted translation data as the entry word Extracting translation data corresponding to the entry word from dictionary data corresponding to the second dictionary type, and displaying the translation data extracted from the dictionary data corresponding to the second dictionary type by the electronic dictionary And a dictionary search method characterized by comprising:

  According to another aspect of the present invention, there is provided a step of inputting character data in a computer that stores a dictionary and a dictionary that stores translation data corresponding to the entry word, and the input character data is input to the entry word. Extracting the translation data corresponding to the entry word from the dictionary data corresponding to the first dictionary type, and using the extracted translation data as the entry word from the dictionary data corresponding to the second dictionary type It is a program for executing a step of extracting translation data corresponding to a headword and a step of displaying translation data extracted from dictionary data corresponding to the second dictionary type.

  According to the present invention, the translation data extracted from the dictionary data corresponding to the second dictionary type using the translation data extracted from the dictionary data corresponding to the first dictionary type as a headword. A dictionary function having no dictionary data can be realized without using. For example, when the dictionary data of the Japanese-English dictionary and the English-Chinese dictionary are held, the electronic dictionary can search the Chinese translation data from the Japanese headword without the dictionary data of the Japanese-Chinese dictionary. This improves the operability of the electronic dictionary.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 is a schematic diagram showing the data structure and data example of the dictionary type table in the present embodiment.
As shown in the drawing, the dictionary type table has columns of items of dictionary type, heading language, and translation data language. The primary key of this dictionary type table is the dictionary type. The dictionary type represents the type of dictionary data held by the electronic dictionary 1. In the example shown in FIG. 3, the electronic dictionary 1 holds dictionary data corresponding to a Japanese-English dictionary, English-Chinese dictionary, Chinese-German dictionary, Western-French dictionary, and French-Japanese dictionary. The heading language is data representing the number of headwords written in the language. A headword is a key for searching dictionary data. The translation data language is data representing the language in which the translation data is written. Translation data includes translations, parts of speech, synonyms, example sentences, and the like, which are the results of searching dictionary data.
In the example shown in FIG. 3, the headword of the Japanese-English dictionary is Japanese and the translation data is English. The English-Chinese dictionary entry word is English, and the translation data is Chinese. In addition, the headword of the Chinese-German dictionary is Chinese, and the translation data is German. In addition, the headword of the Western French dictionary is Spanish, and the translation data is French. The headword of the French-Japanese dictionary is French, and the translation data is Japanese.

FIG. 4 is a schematic diagram showing an example of dictionary data of each dictionary in the present embodiment. The dictionary data holds a headword and translation data corresponding to the headword. The dictionary data is described in an XML (extensible Markup Language) format, and a tag <Hw> represents a headword. Tag <sb> represents supplementary data. A tag <Kj> represents kanji data. A tag <Tr> represents translated data. <Kw> represents keyword data.
In the dictionary data example of the Japanese-English dictionary shown in FIG. 4, “Densha” is a headword, and “train” is kanji data. Further, “a train” is translation data, and “train” is keyword data.

FIG. 5 is a schematic diagram illustrating a data structure and a data example of a route table in the present embodiment.
As shown in the figure, the route table has a dictionary type and a column for each item of the route. The primary key of this route table is the dictionary type. In the path, dictionary types are arranged in series such that the target language of the immediately preceding dictionary type matches the original language. The original language is a language used when looking up a dictionary. The target language is a language obtained as a result of looking up a dictionary. In the example shown in FIG. 5, the path to the Japanese-Chinese dictionary is “Japanese-English, English-Chinese”. The route to the Japanese-German dictionary is “Japanese-English, English-Chinese, English-German”. The route to the English-German dictionary is “English, Chinese, German”.

FIG. 6 is a schematic diagram illustrating the data structure and data example of the conversion table in the present embodiment.
As shown in the figure, the conversion table has a first dictionary type, a second dictionary type, and a column for each rule item. The primary key of this conversion table is a set of the first dictionary type and the second dictionary type. The dictionary type is stored in the first dictionary type and the second dictionary type. In the rule, a rule corresponding to a set of the first dictionary type and the second dictionary type is stored.
In the example shown in the figure, the rule corresponding to the combination of the Japanese-English dictionary and the English-Chinese dictionary is “character string enclosed by <Kw> and </ Kw>”. The rule corresponding to the set of English-Chinese and Chinese-German dictionaries is “a character string enclosed by <Kw> and </ Kw>”. The rule corresponding to the set of the Western French dictionary and the French-Japanese dictionary is “a character string enclosed by <Kw> and </ Kw>”. Further, the rule corresponding to the combination of the French-Japanese dictionary and the Japanese-English dictionary is “a character string surrounded by <Kw> and </ Kw>”.

  Next, with reference to FIG.7 and FIG.8, operation | movement of the electronic dictionary 1 of this embodiment mentioned above is demonstrated. FIG. 7 is a flowchart showing a procedure of the operation of the electronic dictionary 1 in the present embodiment, which is a process when the dictionary type for which the electronic dictionary 1 does not hold dictionary data is selected from the use dictionary selection unit 13. Hereinafter, a case where the user selects the Japanese-English dictionary will be described as an example.

First, in step S1, the user operates the use dictionary selection unit 13 to select the dictionary type of the use dictionary. The control unit 11 detects that the dictionary type has been selected by the user.
Next, in step S2, the control unit 11 acquires a route corresponding to the dictionary type selected in step S1 from the route table. In this example, since the Japanese-Chinese dictionary is selected, the control unit 11 acquires the path “Japanese-English, English-Chinese”.
Next, in step S3, the control unit 11 selects dictionary data corresponding to the dictionary type set at the head of the route acquired in step S2 as a search target. In this example, since the route is “Japanese-English, English-Chinese”, the control unit 11 searches the Japanese-English dictionary.

Next, in step S4, the control unit 11 receives an entry of a headword. That is, the control unit 11 displays an input screen for inputting a headword on the display unit 14. The user operates the character key 21 to input character data. The control unit 11 uses the input character data as a headword.
Next, in step S5, the control unit 11 searches the dictionary data to be searched using the input entry word as a key, and extracts translation data.
That is, the control unit 11 (first extraction means) uses the input character data as a headword, and extracts translation data corresponding to the headword from the dictionary data corresponding to the first dictionary type.

  Next, in step S6, the control unit 11 determines whether or not the next dictionary type is set for the route. If the next dictionary type is set, the process proceeds to step S7. On the other hand, if the next dictionary type is not set, the process proceeds to step S8. In this example, since the English-Chinese dictionary is set as the route after the Japanese-English dictionary, the control unit 11 determines that there is the next dictionary type and proceeds to step S7.

In step S7, the control unit 11 selects dictionary data corresponding to the next dictionary type set in the route as a search target. In this example, the control unit 11 searches for an English-Chinese dictionary.
Next, in step S8, the control unit 11 extracts a headword from the translation data extracted in step S5. Specifically, first, the control unit 11 sets the dictionary type corresponding to the dictionary data searched in step S5 as the first dictionary type, and sets the dictionary type corresponding to the search target dictionary data as the second dictionary type. . Then, a rule corresponding to the set of the first dictionary type and the second dictionary type is acquired from the conversion table. Next, the control part 11 extracts a headword from translation data according to the acquired rule. In this example, the first dictionary type is a Japanese-English dictionary and the second dictionary type is an English-Chinese dictionary. Therefore, the rule acquired by the control unit 11 is “a character string surrounded by <Kw> and </ Kw>”, that is, a keyword. Therefore, the control part 11 extracts a keyword from translation data, and makes the extracted keyword a headword.
That is, the control unit 11 (headword extraction unit) acquires a rule corresponding to the set of the first dictionary type and the second dictionary type from the conversion table, and the first extraction unit according to the acquired rule. The headword is extracted from the translation data extracted by the above.
Then, the control unit 11 returns to step S5, searches the dictionary data to be searched using the extracted entry word as a key, and extracts translation data. In this example, the control unit 11 searches the dictionary data of the English-Chinese dictionary using the English headword as a key, and extracts Chinese translation data.
That is, the control unit 11 (second extraction means) extracts translation data corresponding to the entry word from dictionary data corresponding to the second dictionary type, using the extracted translation data as entry words. The control unit 11 (second extraction unit) extracts translation data from the dictionary data corresponding to the second dictionary type using the headword extracted by the headword extraction unit. Further, the control unit 11 (second extraction unit) repeatedly extracts the translation data sequentially from the dictionary data using the extracted translation data as a headword until the translation data corresponding to the selected dictionary type is extracted. .

On the other hand, in step S9, the control unit 11 (display means) displays the translation data corresponding to the use dictionary extracted in step S5 on the display unit 14. The translation data corresponding to the usage dictionary is translation data whose language matches the target language of the usage dictionary. In this example, since the use dictionary is a Japanese-Chinese dictionary, the control unit 11 displays Chinese translation data on the display unit 14.
Next, in step S10, the control unit 11 determines whether or not the user has started an operation for performing another search, that is, whether or not the character key 21 has been pressed. If the character key 21 is pressed, the process returns to step S4. On the other hand, the control unit 11 ends the process when the power key 20 or the use dictionary selection unit 13 is pressed or when the user does not input for a certain period of time.

  As described above, in the electronic dictionary 1 of the present invention, the dictionary data corresponding to a plurality of dictionary types (Japanese-English dictionary and English-Chinese dictionary) is used to realize the function of a dictionary without dictionary data (Japanese-Chinese dictionary). Can do. In the present embodiment, the type of dictionary to be searched is selected according to the route table, but the route table need not be used. In this case, the control unit 11 sequentially searches the dictionary data until translation data corresponding to the used dictionary (for example, Chinese translation data in the case of a Japanese-to-Japanese dictionary) is acquired. At this time, the control unit 11 sets the dictionary data corresponding to the dictionary type having the language of the acquired translation data as the headword language as the next search target.

FIG. 8 is a flowchart showing a procedure of the operation of the electronic dictionary 1 in the present embodiment, and is processing when the dictionary type in which the electronic dictionary 1 holds dictionary data is selected from the use dictionary selection unit 13.
First, in step S101, the user operates the use dictionary selection unit 13 to select the dictionary type of the use language. The control unit 11 detects that the dictionary type has been selected by the user.
Next, in step S102, the control unit 11 selects dictionary data corresponding to the dictionary type selected in step S101 as a search target.
Next, in step S103, the control unit 11 receives an entry of a headword. That is, the control unit 11 displays an input screen for inputting a headword on the display unit 14. The user operates the character key 21 to input character data. The control unit 11 uses the input character data as a headword.

Next, in step S104, the control unit 11 searches the dictionary data to be searched using the input entry word as a key, and extracts translation data.
Next, in step S105, the control unit 11 displays the translated data extracted in step S104 on the display unit.

  Next, in step S106, the control unit 11 determines whether or not the multi search key 27 has been pressed by the user. If the multi-search key 27 is pressed, the process proceeds to step S107. On the other hand, if the multi-search key 27 has not been pressed, the process proceeds to step S113.

In step S107, the control unit 11 selects all dictionary data corresponding to the input entry word as a search target. Specifically, the control unit 11 selects all the dictionary types whose headline language matches the dictionary type selected in step S101 from the dictionary type table.
In step S108, the control unit 11 searches the dictionary data to be searched using the input headword as a key, and acquires translation data. Then, the control unit 11 temporarily stores all of the acquired translation data as search results in the character data temporary storage unit 16a.

  Next, in step S109, the control unit 11 refers to the dictionary type table to determine whether there is a dictionary type in which the language of the acquired translation data is a heading language. However, the control unit 11 excludes the dictionary type corresponding to the already searched dictionary data from the determination target. If there is one or more dictionary types, the process proceeds to step S110. On the other hand, if there is no dictionary type, the process proceeds to step S112.

In step S110, the control unit 11 selects all dictionary types in which the language of the acquired translation data is the heading language from the dictionary type table, and sets the dictionary data of the selected dictionary as a search target. However, the control unit 11 excludes already searched dictionary data from the search target.
Next, in step S111, the control unit 11 extracts a headword from the translation data acquired in step S108, and returns to step S108. Specifically, first, the control unit 11 sets the dictionary type corresponding to the dictionary data searched in step S108 as the first dictionary type, and sets the dictionary type corresponding to the search target dictionary data as the second dictionary type. . Then, a rule corresponding to the set of the first dictionary type and the second dictionary type is acquired from the conversion table. Next, the control unit 11 extracts a headword from the translation data according to the rule.
In other words, the control unit 11 (second extraction unit) repeats the translation data from the dictionary data using the extracted translation data as a headword as long as the dictionary data has a headword corresponding to the extracted translation data. Extract sequentially.

On the other hand, in step S112, the control unit 11 (display unit) displays on the display unit 14 a list of all translation data temporarily stored as search results in the character data temporary storage unit 16a.
Next, in step S113, the control unit 11 determines whether or not the user has started an operation for performing another search, that is, whether or not the character key 21 has been pressed. When the character key 21 is pressed, the control unit 11 deletes the translation data temporarily stored in the character data temporary storage unit 16a, and returns to step S103. On the other hand, the control unit 11 ends the process when the power key 20 or the use dictionary selection unit 13 is pressed or when the user does not input for a certain period of time.

  In the above-described process, the multi-search process is performed after the use dictionary is selected. However, even when a headword is input from the multi-search screen, the control unit 11 performs steps S107 to S112 described above. Multi-search processing is performed to display translated data in a plurality of languages on the display unit 14. The control unit 11 displays a multiple search screen when the multiple search key 27 is pressed.

Next, a specific example of the multi-search process of the electronic dictionary 1 in this embodiment will be described with reference to FIG. FIG. 9 is a schematic diagram showing which language can be reached directly or indirectly from a Japanese headword in the multi-search process according to the present embodiment. The white arrow in this figure represents the dictionary type of the dictionary data held by the electronic dictionary 1. The thin arrows in this figure represent languages that can be reached directly or indirectly from Japanese headwords. In the example in this figure, the electronic dictionary 1 holds dictionary data of a Japanese-English dictionary, an English-Chinese dictionary, and a Chinese-German dictionary. The electronic dictionary 1 can reach English, Chinese, and German translation data directly or indirectly from a Japanese headword.
(1) First, the control unit 11 selects a Japanese-English dictionary having Japanese as a headline from the dictionary type table, and sets dictionary data corresponding to the selected Japanese-English dictionary as a search target. And the control part 11 acquires English translation data from the dictionary data corresponding to a Japanese-English dictionary by using the inputted headword as a key.
(2) Subsequently, the control unit 11 searches for an English-Chinese dictionary with English as a headword. Next, the control unit 11 acquires the rule “character string enclosed by <Kw> and </ Kw>” from the conversion table, with the front dictionary as the Japanese-English dictionary and the back dictionary as the English-Chinese dictionary. And the control part 11 extracts an English headword according to a rule.
(3) Subsequently, the control unit 11 acquires Chinese translation data from the dictionary data corresponding to the English-Chinese dictionary using the English headword as a key.

(4) Subsequently, the control unit 11 searches for a Chinese-German dictionary having Chinese as a headword. Next, the control unit 11 acquires the rule “character string enclosed by <Kw> and </ Kw>” from the conversion table, with the front dictionary as the English-Chinese dictionary and the subsequent dictionary as the Chinese-German dictionary. Then, the control unit 11 extracts Chinese headwords according to the rules.
(4) Subsequently, the control unit 11 acquires German translation data from the electronic data in the Chinese-German dictionary using the Chinese heading as a key.
(5) Since the electronic dictionary 1 does not hold dictionary data corresponding to a dictionary type in which German is a headword language, the control unit 11 ends the search. Then, the control unit 11 displays the acquired English, Chinese and German translation data on the display unit 14.
Thus, when a Japanese headword is input, the electronic dictionary 1 can display English, Chinese, and German translation data.

Next, a specific example of the entry word extraction process of the electronic dictionary 1 in this embodiment will be described with reference to FIG. FIG. 10 is a conceptual diagram for explaining a headword extraction process in the present embodiment. The electronic dictionary 1 refers to the conversion table and performs the headword extraction process shown in this figure. Reference numeral 100 represents a dictionary type of dictionary data held by the electronic dictionary 1. In addition, the thin arrow shown in this figure indicates that the translated data “character string enclosed by <Kw> and </ Kw>” is the entry word of the corresponding dictionary type.
An example will be described in which a headword in an English-Chinese dictionary is extracted from translation data in a Japanese-English dictionary. The electronic dictionary 1 reads from the conversion table the rule “character string enclosed by <Kw> and </ Kw>” corresponding to the set of the Japanese-English dictionary that is the first dictionary type and the English-Japanese dictionary that is the second dictionary type. get. Then, the electronic dictionary 1 extracts a headword in the English-Chinese dictionary from the translation data according to the acquired rule. The search result of the entry word “densha” using the Japanese-English dictionary is the translation data “a <Kw> train </ Kw>”. For this reason, the electronic dictionary 1 uses the character string “train” surrounded by <Kw> and </ Kw> as the entry word of the English-Chinese dictionary according to the rules shown in FIG.
Further, when extracting the headings of the Chinese-German dictionary from the translation data of the English-Chinese dictionary, the electronic dictionary 1 uses the character string enclosed by <Kw> and </ Kw> as the headword of the Chinese-German dictionary. When the headword of the French-Japanese dictionary is extracted from the translation data of the Western French dictionary, the electronic dictionary 1 uses a character string enclosed by <Kw> and </ Kw> as the headword of the French-Japanese dictionary. In addition, when extracting a headword of the Japanese-English dictionary from the translation data of the French-Japanese dictionary, the electronic dictionary 1 uses a character string surrounded by <Kw> and </ Kw> as a headword of the Japanese-English dictionary.

FIG. 11 is a screen example of a search result displayed on the display unit 14 in the present embodiment.
When the headword is input, the electronic dictionary 1 searches the dictionary data using the input headword as a key, and displays the translation data as the search result on the display unit 14.
FIG. 11A is a screen example of a search result of the Japanese-English dictionary. On the screen shown in FIG. 11A, Japanese headwords and English translation data corresponding to the headwords are displayed. FIG. 11B is a screen example of a search result of the English-Chinese dictionary. On the screen shown in FIG. 11B, English headwords and Chinese translation data corresponding to the headwords are displayed. FIG. 11C is a screen example of the search result of the German-German dictionary. On the screen shown in FIG. 11C, Chinese headwords and German translation data corresponding to the headwords are displayed.
FIG. 11D shows an example of a search result screen in the multi-search process. On the screen shown in FIG. 11D, Japanese headwords and English, Chinese, and German translation data corresponding to the headwords are displayed. When the multi-search key 27 is pressed after the screen shown in FIG. 11A is displayed, the electronic dictionary 1 displays the screen shown in FIG.

FIG. 12 is another screen example of the search result displayed on the display unit 14 in the present embodiment.
In the example shown in this figure, the electronic dictionary 1 holds dictionary data of a Japanese-Chinese dictionary, a Japanese-French dictionary, a French-English dictionary, and an English-West dictionary. When the headword is input, the electronic dictionary 1 searches the dictionary data using the input headword as a key, and displays the translation data as the search result on the display unit 14.
FIG. 12A is a screen example of the search result of the Japanese-Chinese dictionary. On the screen shown in FIG. 12A, Japanese headwords and Chinese translation data corresponding to the headwords are displayed. FIG. 12B is a screen example of a search result of the Japanese-French dictionary. On the screen shown in FIG. 12B, Japanese headwords and French translation data corresponding to the headwords are displayed. FIG. 12C is a screen example of a search result of the French-English dictionary. On the screen shown in FIG. 12C, French headwords and English translation data corresponding to the headwords are displayed. FIG. 12D is a screen example of the search result of the English-West dictionary. On the screen shown in FIG. 12D, English headwords and Spanish translation data corresponding to the headwords are displayed.
FIG. 12E shows an example of a search result screen in the multi-search process. On the screen shown in FIG. 12D, Japanese headwords and translated data of Chinese, French, English, and Spanish corresponding to the headwords are displayed. When the multi-search key 27 is pressed after displaying the screen shown in FIG. 12A, the electronic dictionary 1 displays the screen shown in FIG.

  Thus, according to the present embodiment, translation data is searched from input character data, headwords are extracted from the searched translation data, and translation data is searched from dictionary data of other dictionaries. A dictionary function having no dictionary data can be realized without using the switching or jump function. In addition, a plurality of languages including a language having no bilingual dictionary can be searched from one language by the multi-search process. In the example shown in FIG. 11, it is possible to search from Japanese including Chinese and German without a bilingual dictionary (Japanese-Chinese dictionary, Japanese-German dictionary). Thereby, the operability of the electronic dictionary 1 is improved.
