  Search unit 150 can generally be referred to as search means.

  The search unit 150 searches the example sentences in the example sentence database 120 for example sentences including at least one of the keyword 201 and the translated word keyword included in the translated word phrase list 600 from the English example sentences indicated by the language information 301. For example, the search unit 150 selects one of the search words included in the translated phrase list 600 and the synonym phrase list 601 from the English example sentences indicated by the language information 301 among the example sentences in the example sentence database 120, and the keyword 201. Search for example sentences that contain it. In the present embodiment, the search unit 150 includes an example sentence search unit 151 and a search result output unit 152.

  The example sentence search unit 151 receives the language information 301 indicating English from the input unit 130, receives the translated word phrase list 600 from the translation unit 141, receives the synonym phrase list 601 from the synonym search unit 142, and further receives the synonym phrase list 601 from the search expression output unit 143. A search expression 700 is accepted.

  The example sentence search unit 151 uses, based on the search expression 700, an example sentence including a phrase obtained by combining any one of the search words and the keyword 201 from the English example sentences indicated by the language information 301 among the example sentences in the example sentence database 120. To search.

  The example sentence search unit 151 searches for an English example sentence based on the search expression 700, and generates an example sentence list indicating the result. For example, the example sentence search unit 151 generates the example sentence list 800 shown in FIG. The example sentence search unit 151 outputs the example sentence list 800 to the search result output unit 152.

  When the search result output unit 152 receives the example sentence list 800 from the example sentence search unit 151, the search result output unit 152 generates search result information using the example sentence list 800 and displays the search result information. The search result information includes, for example, search result main information and search result detailed information.

  The detection result output unit 152 sorts and groups the example sentences shown in the example sentence list 800 using a specific algorithm. For example, the search result output unit 152 calculates the total number of example sentences including the search word among the example sentences indicated in the example sentence list 800 for each search word included in the translated word phrase list 600 and the synonym phrase list 601, The example sentences shown in the example sentence list 800 are sorted in order from the example sentence including many search words. The search result output unit 152 groups the example sentences shown in the example sentence list 800 for each search word.

  In addition, the search result output unit 152, for each search word, a combined phrase of the search word and the keyword 201 (hereinafter referred to as “combination phrase”) and the total number of example sentences including the search word among the example sentences shown in the example sentence list 800. Are displayed as search result main information. When the search result output unit 152 receives from the input unit 130 specified word information indicating the search word specified by the user among the search words, the search result output unit 152 includes the search word indicated by the specified word information among the example sentences shown in the example sentence list 800.

The search result main information 901 includes a combination word / phrase of the search word and the keyword 201 in order from the combination word / phrase “valid value” having the largest total number of example sentences among the combination words / phrases of the search word and the keyword 201. , And the total number of example sentences including combination words.

  FIG. 7B is a diagram illustrating an example of detailed search result information. The search result detailed information 902 shows an example sentence including the combination word “valid Value”. The user can follow the search result detailed information 902 from the search result main information 901.

  The example sentence search apparatus 100 may be realized by a computer. In this case, the computer reads and executes a program recorded on a recording medium such as a CD-ROM (Compact Disk Read Only Memory) readable by the computer, thereby executing the input unit 130, the search expression generation unit 140, and the search. It functions as the unit 150. The recording medium is not limited to the CD-ROM and can be changed as appropriate.

  Next, the operation of the example sentence search apparatus 100 will be described.

  FIG. 8 is a flowchart illustrating a processing procedure example of the processing method of the example sentence search apparatus 100. FIG. 8 illustrates an example in which a user inputs a Japanese keyword 200 and an English keyword 201 in order to search for an English example sentence.

  First, the input unit 130 receives the keyword 200 and the keyword 201. Further, the input unit 130 receives language information 300 indicating Japanese specified as the language of the keyword 200 and language information 301 indicating English specified as the language of the keyword 201.

  When receiving the language information 300 indicating Japanese, the language information 301 indicating English, and the keyword 200 from the input unit 130, the translation unit 141 receives a Japanese-English dictionary in the dictionary database 110 based on the language information 300 and the language information 301. The Japanese keyword 200 is translated into an English phrase by referring to the information. That is, the translation unit 141 detects an English phrase associated with the Japanese keyword 200 indicated by the language information 300 as a translated word keyword from the English phrases indicated by the language information 301 among the phrases in the dictionary database 110. Then, a translated word / phrase list 600 including the translated keyword is generated (step A1). The translation unit 141 outputs the translated word phrase list 600 to the synonym search unit 142 and the search expression output unit 143.

  Upon receiving the translated word phrase list 600, the synonym search unit 142 refers to the dictionary database 110 and searches for a synonym of the translated keyword included in the translated word phrase list 600 (step A2). The synonym search unit 142 searches for the synonym of the translation keyword for each translation keyword included in the translation word phrase list 600. When the synonym of the translation keyword is detected, the synonym search unit 142 adds the synonym as a synonym keyword to the synonym phrase list 601 (step A3). ). That is, the synonym search unit 142 detects, as synonym keywords, synonyms associated with the translated keyword among the synonyms of English phrases in the dictionary database 110.

  Subsequently, the search expression output unit 143 generates the search expression 700 using the translated word phrase list 600, the synonym phrase list 601 and the keyword 201 (step A4). For example, as shown in FIG. 4, the search expression output unit 143 performs an “AND” operation by combining all search words included in the translated word phrase list 600 and the synonym phrase list 601 with “OR” and the keyword 201. A search expression 700 to be linked is generated. The search expression output unit 143 outputs the search expression 700 to the example sentence search unit 151.

  Upon receiving the search expression 700, the example sentence search unit 151 searches for an English example sentence based on the search expression 700, and generates an example sentence list 800 indicating the search result (step A5). As a result, the example sentence search unit 151 can generate an example sentence list 800 showing example sentences including the keyword 201 and an English search word related to the keyword 201.

  When the example sentence search unit 151 detects a plurality of example sentences, for each search word included in the translated word phrase list 600 and the synonym phrase list 601, the example sentence search unit 151 calculates the total number of example sentences including the search word among the plurality of example sentences, The example sentence list 800 may be generated by sorting the example sentences in order from the example sentence including the search word having the largest total number of example sentences.

  The example sentence search unit 151 confirms the example sentence list 800 indicating the search result of the example sentence (step A6). If there is no corresponding example sentence and no example sentence is shown in the example sentence list 800, the example sentence search unit 151 displays that the search result is zero (step A8) and ends the process. The example sentence search unit 151 outputs the example sentence list 800 to the search result output unit 152 when the example sentence list 800 shows that the example sentence list 800 is detected.

  The search result output unit 152 generates and displays search result information using the example sentence list 800 (step A9). The search result information includes search result main information 901 and search result detailed information 902.

  The search result output unit 152 sorts and groups the example sentences shown in the example sentence list 800 based on the search words included in the example sentences shown in the example sentence list 800. Then, for each search word included in the example sentence shown in the example sentence list 800, the search result output unit 152 displays the combination word / phrase of the search word and the keyword 201, the total number of example sentences including the search word, The search result main information 901 is displayed in order. Further, according to the search word designated by the user, the search result output unit 152 displays, as the search result detailed information 902, an example sentence including the search word for each search word.

And a dictionary database 110 that stores them in association with each other. When the input unit 130 receives an English keyword (predetermined phrase) and a Japanese keyword (specific phrase), the search expression generation unit 140 selects a Japanese keyword out of the English phrases in the dictionary database 110. The associated translation is detected as a translation keyword. Then, the search unit 150 searches the example sentences in the example sentence database 120 for example sentences including at least one of an English keyword and an English translation keyword, and outputs a search result.

  For this reason, the example sentence search apparatus 100 can search for an English example sentence based on keywords in different languages of Japanese and English. That is, the example sentence search device 100 can search for an example sentence in a specific language based on keywords in a plurality of different languages.

  Therefore, users who are good at Japanese but are not good at English can specify not only English keywords but also good Japanese keywords, so it is possible to search for English example sentences desired by users. It becomes easy. For this reason, the example sentence search device 100 can more appropriately provide the user with the example sentence desired by the user.

  In the present embodiment, the dictionary database 110 stores English words and synonyms of English words in association with each other, and the search expression generation unit 140 stores the synonyms of English words in the dictionary database 110. Among them, a synonym associated with the translated word keyword is detected as a synonym keyword. The search unit 150 searches an example sentence in the example sentence database 120 for an example sentence including either the translated keyword or the synonym keyword and an English keyword, and outputs the search result.

  Therefore, the example sentence search device 100 can search for an example sentence including the English keyword received from the input unit 130 and the English translation keyword or the synonym keyword related to the Japanese keyword.

  Further, in the present embodiment, the search unit 150 searches the example sentences in the example sentence database 120 for example sentences including either translated word keywords or synonym keywords and English keywords. When the search unit 150 detects a plurality of example sentences, for each search word of the translated word and the synonym keyword, the search unit 150 includes a total number of example sentences including the search word, a search word and an English keyword, Is displayed.

  Therefore, the user can use the example sentence search device 100 to examine a phrase that is desired to be combined with a predetermined English phrase. For example, when examining a phrase to be combined with an English phrase “value”, the user inputs a Japanese keyword “appropriate” and an English keyword “value” representing the semantic content of the phrase to be combined.

  Upon receiving the Japanese keyword “appropriate” and the English keyword “value”, the example sentence search device 100 detects a plurality of English search words close to the semantic content of the Japanese keyword, ”And“ value ”are searched for example sentences including a combination word / phrase.

  Then, when a plurality of example sentences are detected, the example sentence search apparatus 100 displays, for each search word, a combination word / phrase of “search word” and “value” and a total number of example sentences including the combination word / phrase. Therefore, the user can know the combination word / phrase having the largest total number of example sentences among the combination words / phrases of “search word” and “value”. Therefore, the example sentence search device 100 can provide the user with the tendency of frequently used word combinations.
