Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a translation example sentence search device for searching a translation example sentence database for accumulating translation example sentences each including a set of sentences expressing the same content in a plurality of languages.

[0002]

2. Description of the Related Art When translating, a translation example sentence database in which translation example sentences each containing a set of sentences expressing the same content in a plurality of languages are stored is searched and referred to. (For example, "Practical Search Method for Similar Examples for Translation Support", Sumida, Tsutsumi, IEICE Transactions D-II,
Vol. J74-D-II, No. 10, pp. 143
7-1447, October 1991).

A conventional translation example sentence search device will be described below. FIG. 11 is a block diagram of a conventional translation example sentence search device. In FIG. 11, reference numeral 43 denotes a translation example database section for accumulating translation example sentences in which a set of sentences expressing the same content in a plurality of languages is set. For example, as shown in FIG. It is stored together with the parsed tree structure.

Reference numeral 41 denotes an input unit for inputting an input sentence for determining a keyword to be used when searching the translation example sentence stored in the translation example sentence database 43. Reference numeral 42 is a keyword generation unit that performs morphological analysis, syntactic analysis, semantic analysis, etc. of the input sentence,
Phrases, characteristic syntaxes, etc. are extracted, unsuitable keywords are deleted from the extracted independent words, clauses, phrases, characteristic syntaxes, etc., and the remaining ones are used as keywords.

A search unit 44 searches the translation example sentence database unit using the keyword determined by the keyword generation unit 42 and extracts the translation example sentence including the keyword. A display unit 45 displays the search result of the search unit 44. The operation of the conventional translation example sentence search device as described above will be described below.

First, the user inputs an input sentence into the input unit 41.
Entered in. The input unit 41 outputs the input sentence to the keyword generation unit 42. The keyword generation unit 42 performs morphological analysis, syntactic analysis, and the like on the input sentence received from the input unit 41, and extracts independent words, clauses, phrases, and characteristic syntaxes. For example, if "I saw the taste of stew" is entered, "I", "stew", and "taste" as independent words
“See” is extracted, and it is extracted that the sentence “see taste” is embedded as the syntax.

Next, the keyword generation unit 42 determines whether or not there are overlapping notations as a process for deleting inappropriate keywords as keywords from the extracted independent words, clauses, phrases, characteristic syntaxes, and the like. However, if there is one, the processing to combine them is performed. In this case, there are no duplicates, so
"I", "stew", "taste", "see", and "see taste" are determined as keywords for searching the translation example sentence database unit 43. These keywords are output to the search unit 44.

The search unit 44 searches the translation example sentence database unit 43 using the keyword received from the keyword generation unit 42. All translated example sentences that include even one keyword are searched. 1 A translation example sentence is ranked as it is a translation example sentence that should be searched, as the number of keywords included in the translation example sentence increases. All of these search results are output to the display unit 45.

The display unit 45 displays the search result and informs the searcher of the search result.

[0010]

The above-described conventional translation example sentence search device has the following problems. By the way, in the translation example sentence stored in the database, the stored sentence is not always in correspondence with each word of the sentence unless it is a direct translation.

Therefore, for example, "He investigated the cooking process", "He tas, which is relatively close to the English translation of the input sentence.
Even if "ted the stew" is stored in the translation example sentence database as a set of translation example sentences, the keyword "I" is included in "He investigated the dish".
Since there is no match for "stew", "taste", "see", and "see taste", there is a problem that the search cannot be performed and a search omission occurs.

If such an omission of the search occurs, if the number of search example sentences displayed as the search result is large, it is possible to find an example sentence to be used as a reference for translation from many example sentences. When there are few, it is easy for the user to find a reference example sentence, which is not convenient for the user.

Further, in the above method, for example, when "he did something tasty" and "he grew up while watching" was stored in the translation example sentence database, the keyword "taste",
It matches with "see", so even if the meaning is completely different, it will be searched. Therefore, there is a problem that many extra translation example sentences are displayed as search results.
In particular, when the number of search example sentences displayed as the search result is large, it is difficult for the user to see the example sentences and the usability is poor.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a convenient translation example sentence retrieval device in which search omissions and extra translation example sentence display are unlikely to occur. To do.

Specifically, it is realized by using a keyboard or OCR. The language of the input sentence input from the input unit 1 will be referred to as the first language hereinafter.

Reference numeral 2 is a first language keyword generation unit, which performs morphological analysis, syntactic analysis, semantic analysis, etc. of an input sentence.
Independent words, phrases, phrases, characteristic syntaxes, etc. are extracted, unsuitable keywords are excluded from the extracted independent words, phrases, phrases, characteristic syntaxes, etc., and the remaining ones are given first. It is used as a language keyword. Reference numeral 4 denotes a second language keyword generation unit, which refers to a word dictionary unit 3 described later,
Independent words, clauses, phrases, characteristic syntaxes, etc. extracted from the input sentence by the first language keyword generation unit 2 are converted into a language other than the first language, that is, a second language, and the keywords are selected from the conversion results. Is deleted, and the second language keyword is used as.

Reference numeral 3 is a word dictionary section in which words, phrases, syntaxes and the like of the first language and the second language are registered in association with each other. Specifically, it is composed of a ROM and a magnetic disk device. Reference numeral 5 denotes a translation example sentence database section, which stores at least translation example sentences expressing the same sentence in a combination of the first language and the second language,
For example, as shown in FIG. 2, it is stored together with the tree structure.

The types of translation example sentences stored in the translation example sentence database unit 5 are not limited to two types, and can be stored even if there are two or more types. A first language search unit 6 searches the translation example sentence database unit 5 using the first language keyword and extracts the translation example sentence including the first language keyword. Further, it detects how many first language keywords are included in the first language sentence of the extracted translation example sentence.

Reference numeral 7 denotes a second language search unit, which searches the translation example sentence database unit 5 using the second language keyword and extracts the translation example sentence including the second language keyword. Further, it detects how many second language keywords are included in the second language sentence of the extracted translation example sentence. Reference numeral 8 denotes a search result integration unit, which is a first language search unit 6,

Next, regarding the processing operation of the translation example sentence search device configured as described above, the first language is Japanese, the input sentence is “I saw the taste of stew”, and the second language is English. The description will be given below.

First, in order to retrieve a translation example sentence, the input sentence "I saw the taste of stew." Is input to the input unit 1. The input unit 1 converts the input sentence into the first language keyword generation unit 12
Output to. The first language keyword generation unit 12 performs morphological analysis, syntactic analysis, and the like on the input sentence received from the input unit 1, and extracts independent words, clauses, phrases, characteristic syntaxes, and the like. Here, "I", "stew", "taste" and "see" are extracted as independent words from the input sentence "I see the taste of stew", and "see the taste" is extracted as the syntax.

Next, in the first language keyword generation unit 2, as a process of deleting the unsuitable keywords from the extracted independent words and the like, a process of combining duplicate expressions is performed. In this case, since there is no overlapping expression, “I”, “stew”, “taste”, “see”, and “see the taste” are the first language keywords for searching the translation example sentence database unit 5. These results are delivered to the first language search unit 6.
In addition, the input sentence is parsed and independent words, clauses,
When the phrase, the characteristic syntax, etc. are extracted, the extracted independent words, clauses, phrases, characteristic syntax, etc. are output to the second language keyword generation unit 4.

The first language search unit 6 uses the first language keywords "I", "stew", "taste", "see" and "see taste" received from the first language keyword generation unit 2 as shown in FIG. The translation example sentence database unit 5 is searched. All translation example sentences including at least one first language keyword are searched. In addition, the number of first language keywords included in one translation example sentence is detected, and the larger the number of keywords, the more the translation example sentence is to be searched, and the ranking is performed (see FIG. 3). These search results are delivered to the search result integration unit 8.

On the other hand, the second language keyword generator 4 receives the morphological analysis of the input sentence from the first language keyword generator 2,
Independent words, phrases, phrases in the first language obtained by syntactic analysis,
It receives a characteristic syntax or the like and converts it into a second language by referring to the word dictionary unit 3. Therefore, as shown in FIG. 4, the independent words “I”, “stew”, “taste”, “see”, and the syntax “see the taste” extracted by the first language keyword generation unit 2 are
Second language "I", "stew", "tast"
e "," look "," taste ". When this first language is converted to a second language, there are multiple translations for" see "and other" see " , ”
“Watch” and the like are also added. Next, as a process of deleting inappropriate keywords from the conversion result, a process of combining duplicate expressions is performed. In this case, “test” appears twice. Delete one,
Determine second language keywords. These results are output to the second language search unit 7.

The second language search section 7 searches the translation example sentence database section 5 using the output second language keyword. All translation example sentences including at least one second language keyword are searched, and the one having a larger number of keywords in one translation example sentence is regarded as a translation example sentence to be searched and ranked (see FIG. 5). These search results are stored in the search result integration unit 8
Is output to.

A set of search procedures 33 and 34 and 35,
The processing order of the 36 sets may be reversed, and the processing may be performed in parallel. The search result integration unit 8 refers to the translation example sentences searched by the first language search unit 6 and the second language search unit 7, sets the same search result to one, and searches the search results of both search units 6 and 7. Are summarized as shown in FIG.

Next, the number of retrieved translation example sentences is checked,
A comparison is made with a fixed number set in advance. When the number of translation example sentences retrieved is greater than a certain number, the translation example sentences with the number of keywords in the first language being 0 and the number of keywords in the second language being 0 are deleted and displayed. , The integration of the search results ends. The integration result is as shown in FIG.

When the number of retrieved translation example sentences is smaller than the predetermined number, a search decision is made to display all the translation example sentences, and the integration of the search results is completed. The integrated result is as shown in FIG.

Further, in the search result integrating section 8, the number of first language keywords included in the searched translation example sentences,
The numbers of the second language keywords included in the retrieved translation example sentences are added, and the larger the added number is, the more the translation examples should be searched, and the ranking is performed. Based on the ranking determined in, the search result can be displayed as shown in FIG. 9, for example.
