Abstract

PURPOSE:To process an input sentence including the quotation marks by means of the same grammar rule as an input sentence including no quotation mark, by storing the positions of quotation marks and producing a sentence where the quotation marks are once deleted. CONSTITUTION:The position of each word is indicated in an input sentence and presence or absence of the quotation marks is checked. If the quotation marks are included in the sentence, a fact that the mark shows an opening double-fort quotation mark (') is stored together with the position of the word having the mark. Then a closing quotation mark (') is searched and stored together with the position of the word having this mark. In case the input sentence includes no quotation mark excluding the searched ones, the quotation marks of the stored position are erased out of a buffer for input sentences. As a result, the subsequent dictionary consulting and morpheme analyzing processes are equal to those applied to an input sentence including no quotation mark. The translation processing is carried out by a CPU 1 based on a program stored in a main memory 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a machine translation device, and more particularly to a translation device capable of processing quotation marks appearing at arbitrary positions in an input sentence.

<Prior Art> Conventionally, machine translation devices have been configured to process a quotation symbol representing quotation 2 emphasis, etc. as one word.

However, because quotation marks appear in various positions in the source language, the grammar for parsing the source language during the translation process becomes complicated, making it difficult to see the entire grammar using conventional devices, and making it difficult to maintain and manage the grammar. There were drawbacks that made it difficult.

<Object of the Invention> In view of the above circumstances, the present invention stores the position where a quotation mark appears in a sentence in an input source language, and creates a sentence with the quotation mark removed. Provided is a machine translation device that performs translation processing on a sentence from which symbols have been deleted, outputs quotation marks at the memorized position when generating a target language, and converts an input sentence with quotation marks into an input sentence without quotation marks. The purpose is to make it possible to process using the same grammar rules and to make the grammar rules more compact.

<Example> Hereinafter, the configuration of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a machine translation device according to an embodiment of the present invention.

In the figure, l is a central processing unit CPU that performs translation processing.

2 is a main memory in which programs for translation processing are stored, 3 is a CRT display device for displaying translated sentences, 4 is a keyboard for inputting input sentences, and 5 is an output sentence of the input sentences (original sentences). This is a translation module that executes conversion to (translated text). The translation module 5 includes a dictionary 2 grammar rules for translation.

A table 6 of tree structure conversion rules is connected.

Specifically, the configuration of the translation module 5 is shown in FIG.

As shown in the figure, the translation module 5 includes a dictionary lookup morphological analysis unit 5a into which the source language is input.

It consists of a syntax analysis section 5b, a conversion section 5c, and a generation section 5d that generates a target language.

The dictionary lookup morphological analysis unit 5a looks up the translation dictionary of the table 6 and extracts grammatical information such as part of speech for each word,
Obtain translations and analyze tense, person, number, etc.

Further, the syntax analysis unit 5b determines the structure of the sentence, such as the dependencies between words.

The internal structure of the source language is obtained by the analysis performed by the parser 5b, and the converter 5c converts the target language into a structure at the same level.

Thereafter, the target language is generated by the generation unit 5C.

FIG. 3 shows a processing flowchart of the translation module.

Here, as shown in Figure 4, "I bout ac
ar “with 1000 dollars”
” is input. A word position is assigned to each word in the input sentence (Sl step).

In the next step 82, a search is made to see if a quotation mark exists in the input sentence.

The above input sentence contains a double fort (“) which is a quotation mark.
exists, the process moves from step S3 to step 84, and the word position 4 where the quotation mark exists and the fact that the symbol is an open quotation mark (for example, ") in Japanese are stored.

The process then moves to step 85 to search for a closing quotation mark (eg, "" in Japanese).

Then, the process moves from step S6 to step 87, and the word position 6 where the quotation mark exists and the fact that the quotation mark is a closing quotation mark are stored. Here, the reason why the word position is set to 6 instead of 7 is that in the case of a period at the end of a sentence, the previous word position is stored for convenience of generation. If a plurality of quotation mark pairs exist in other input sentences, the processes from step S2 to step S7 are repeated.

Returning to the input sentence again (step S2), there are no quotation marks other than those already searched, so step S3
The process moves from step 89 to step 89, and the quotation mark at the memorized position is deleted from the buffer of the input sentence. As a result, a sentence was created by removing the quotation mark from the input sentence.

As a result, subsequent dictionary lookup processing (510 steps)
The morphological analysis process (step S11) is the same as the process for an input sentence without a quotation mark.

Also, in the syntax analysis at step S12, it is no longer necessary to provide a grammar rule for processing quotation marks.

As described above, in step 513, the conversion process is performed as if the quotation symbol did not exist, and as shown in Figure 5, a tree structure (a data structure showing the modification, the modified, and the semantic relationships between input words) is performed. ). This tree structure becomes the output structure to the generation unit in the next process.

The generation unit determines whether or not the word position of the phrase to be generated matches the content stored in steps S4 to S7.

(Step S14) Here, a phrase refers to a group of one or more words such as a verb phrase, a noun phrase, and a prepositional phrase, as is clear from FIG. During generation, translations are generated phrase by phrase according to word order information in the target language.

In step 514, the word position of the phrase to be generated and the S
If it is determined that the stored contents match in step 4 + 57, the flag is turned on (step S15).
Generate an open quotation mark ([) (step S16) 0 On the other hand, if it is determined in step 514 that the two positions do not match, generate a phrase (step S17) 0 Then, in step 818 It is identified whether the flag is ON or OFF, and if it is ON, a closing quotation mark ('') is generated. S1
(9 steps), and when it is OFF, proceed to step 520.

The step 520 is provided to confirm that all phrases have been generated, and after turning off the flag (step S21) until the generation of all phrases is completed, the process returns to the step 514.

Specifically, after the noun phrase "I" is generated, when the preposition direction shown in FIG. 5 is generated, a match is determined in step S14. Therefore, in this case, the flag for generating the closing quotation mark ('') is turned ON in step S15.
becomes. Then, in the steps 516 and 517, "1000 dollars" is generated, and then in the step 518, it is determined that the flag is ON, and then the flow goes to step 519. Then, a closing quotation mark is generated. When the generation of the remaining phrases is completed, the translated text is displayed on the display device 3, as shown in FIG.
will be displayed.

Translation examples of other input sentences in which quotation marks appear are shown in FIGS. 7 and 8.

<Effects> As described above, according to the present invention, an input sentence can be analyzed, converted, and
A translation device that executes a generation process and outputs a translated sentence includes a search means for searching for a quotation mark in an input sentence, a storage means for storing the position of the quotation mark searched by the search means, and erasing the quotation mark. a creating means for creating a sentence created by the creating means; a translation means for performing translation processing on the sentence created by the creating means; Since the system is equipped with a generating means for generating quotation marks, input sentences containing quotation marks can be processed using the same grammar rules as input sentences without quotation marks, and the grammar rules can be made compact.
