Abstract

A translation system comprises an image reading unit that optically reads an image of a manuscript and generates image data; an inputting unit that inputs a translation target language; a character recognizing unit that generates an original text by performing a character recognition process on the image data generated by the image reading unit; a translation text database in which are associated and stored translation texts, language identifiers which specify the languages in which the translation texts are written, and document identifiers which specify the contents of the translation texts; an extracting unit that extracts the document identifier which specifies the content of the original text from the original text; a searching unit that searches the translation text database for a translation text associated with a document identifier identical to the document identifier extracted from the original text by the extracting unit and a language identifier identical to the language identifier which specifies the translation target language input by the inputting unit; and an outputting unit that outputs the translation text searched by the searching unit.

Claims

1. A translation system comprising:

an image reading unit that optically reads an image of a manuscript and generates image data;

an inputting unit that inputs a translation target language;

a character recognizing unit that generates an original text by performing a character recognition process on the image data generated by the image readingunit;

a translation text database in which are associated and stored translation texts, language identifiers which specify the languages in which the translation texts are written, and document identifiers which specify the contents of the translation texts;

;

an extracting unit that extracts the document identifier which specifies the content of the original text from the original text;

a searching unit that searches the translation text database for a translation text associated with a document identifier identical to the document identifier extracted from the original text by the extracting unit and a language identifier identical to the language identifier which specify the translation target language input by the inputting unit; and

an outputting unit that outputs the translation text searched by the searchingunit.

4. The translation system according to either claim 1, further comprising a notifying unit that notifies that the searching unit can find no translation texts that satisfy the condition in the translation text database, if none can be found.

6. The translation system according to either claim 1, further comprising a translating unit that generates a translation text by translating the original text into the translation target language if no translation texts satisfying the condition can be found in the translation text database.

2. A translation system comprising:

an image reading unit that optically reads an image of a manuscript and generates image data;

an inputting unit that inputs a translation target language;

a character recognizing unit that generates an original text by performing a character recognition process on the image data generated by the image readingunit;

a translation text database in which are associated and stored translation texts, the language identifiers which specify the languages in which the translation texts are written, and intermediate language texts generated from the translation texts;

an intermediate language generating unit that translates the original text into an intermediate language and generates an intermediate language text;

a proximity calculating unit that calculates the proximity between the intermediate language text obtained by the intermediate language generating unit and the intermediate language text stored in the translation text database; and

a searching unit that searches the translation text database for a translation text whose proximity calculated by the proximity calculating unit satisfies a prescribed condition and which is associated with a language identifier identical to the language identifier which specify the translation target language input by the inputting unit.

3. The translation system according to claim 2, wherein the prescribed condition is the condition that a minimum value of the proximities calculated by the proximity calculating unit be not greater than a threshold value.

5. The translation system according to either claim 2, further comprising a notifying unit that notifies that the searching unit can find no translation texts that satisfy the condition in the translation text database, if none can be found.

7. The translation system according to either claim 2, further comprising a translating unit that generates a translation text by translating the original text into the translation target language if no translation texts satisfying the condition can be found in the translation text database.

8. A translation method for translating a manuscript according to a translation text database in which are associated and stored translation texts, language identifiers which specify languages in which the translation texts are written, and document identifiers which specify content of the translation texts, the method comprising:

optically reading an image of a manuscript and generates image data;

inputting a translation target language;

generating an original text by performing a character recognition process on the image data;

extracting from the original text a document identifier which specifies the content of the original text;

searching the translation text database for a translation text associated with a document identifier identical to the document identifier extracted from the original text by the extracting step and a language identifier identical to the language identifier which specifies the input translation target language; and

outputting the searched translation text.

9. A translation method for translating a manuscript according to a translation text database in which are associated and stored translation texts, language identifiers which specify languages in which the translation texts are written, and intermediate language texts generated from the translation texts, the method including:

generating an original text by performing a character recognition process on the image data;

generating an intermediate language text by translating the original text into an intermediate language;

calculating the proximity between the intermediate language text and the intermediate language text; and

searching the translation text database for a translation text whose proximity satisfies a prescribed condition and which is associated with a language identifier identical to the language identifier which specifies the input translation target language.

10. A storage medium readable by a computer, the storage medium storing a program of instructions executable by a computer device, the computer device including a translation text database in which are associated and stored translation texts, language identifiers which specify languages in which the translation texts are written, and document identifiers which specify content of the translation texts, the program comprising:
