Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects, via a communication network, a server device having a translation function and capable of providing document data translated into a desired language, and a client device capable of displaying document data. And a multi-language communication system.

[0002]

2. Description of the Related Art Conventionally, a system for searching and browsing document data via a communication network, such as the Internet, has become widespread. Such a system,
It comprises at least one server device for storing various types of document data, at least one client device capable of displaying document data, and a communication network connecting them. Communication networks include public networks,
It is composed of a dedicated line network or a combination thereof. The server device includes a storage device capable of storing various types of document data, and a connection device to a communication network.The client device includes a display device capable of displaying document data, and an input device capable of inputting instruction information of a document to be viewed. And a connection device to a communication network.

[0003] For example, on the Internet, a great number of devices are connected to both server devices and client devices, and their locations are spread all over the world. And
The system is capable of searching and browsing various information in various parts of the world via a communication network connecting them.

In the Internet, as shown in FIG. 15, each server device 1502 stores document data described in various languages such as English, Japanese, and Chinese. The client device 1503 connected to the server device via the communication network 1501 can display the document data described in these various languages in the respective languages. There is also a client device having a built-in language translation program, and it is possible to display the document data by translating it into a desired language as needed.

[0005]

SUMMARY OF THE INVENTION When browsing various document data via the above-mentioned system, particularly a network spread all over the world such as the Internet, a document data provider and a viewer of the document data need to communicate with each other. Often use a different language as their native language. However, writing and understanding in languages other than the native language is often difficult.
To solve this, the following two methods are known.
One is to store a document having the same content as a plurality of document data described in a plurality of languages in a server device, and select document data in a desired language from a client device to thereby obtain a document described in a desired language. This is a method that allows data to be browsed. Another method is to mount a language translation program on a client device and use the language translation program to translate document data transmitted from a server into document data in a desired language. With these methods, document data described in a language other than the native language can also be browsed in the native language. However, even in that case, the following problems remain.

First, in a method of storing a document having the same content as a plurality of document data described in a plurality of languages in a server device, even if a document has a single content, a plurality of documents having the same content described in various languages are stored. There is a problem that it needs to be created as data and requires a lot of cost and labor.

In the method in which a language translation program is mounted on a client device, in order to translate and display all sentences in various languages provided by each server, the client device converts the language from a desired language into a desired language. It is necessary to have a large number of language translation programs that can be translated. This increases the cost of the client device. Further, in a language translation program currently in practical use, there is a problem that a desired translation result cannot be obtained due to the ambiguity originally included in the original document to be translated.

In order to solve this problem, Japanese Patent Application No. 8-322842 filed by the present applicant describes that document data stored in a server device is not natural language described document data but natural language. Is stored as intermediate format document data obtained as a result of grammatically and semantically analyzing the document data described in. When there is a request for document data from the client device, the intermediate format document data corresponding to the document data is read from the storage device, and from the read intermediate format document data, the document data described in the natural language requested by the client device is converted. The generated document data is transmitted to the client device. As described above, a multilingual communication system that does not require a special language translation program in a client device and that can easily provide document data described in many languages is described.

[0009] However, even in such a proposed multilingual communication system, the following problems remain.

[0010] Document data described in a natural language from which the intermediate format document data is created contains a lot of ambiguity, and even if it is grammatically and semantically analyzed, a desirable intermediate format document data is not obtained. May not be generated. As a result, the meaning of the document data described in the natural language generated by the server device is different from the document data described in the natural language based on which the intermediate format document data is created. Furthermore, in order to generate the desired intermediate format document data, it is necessary to modify the document data in order to remove the ambiguity of the document data described in the natural language from which the intermediate format document data is created. There was a problem that should not be.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a multilingual communication system capable of easily generating desirable intermediate format document data.

[0012]

In order to achieve the above object, according to the present invention, there is provided a multi-language communication system, wherein the client device and the document data in response to a request from the client device. And a server device for transmitting to the client device. In the client device, request information transmitting means transmits document identification information capable of specifying desired document data and request language information for specifying a description language of the document data to the server device, and the reception output means Receiving document data from the server device and performing output processing such as display output, print output, and voice output.

[0013] In the server device, request information receiving means receives the document identification information and the request language information from the client device, and the intermediate format document storage means grammatically converts a document described in a natural language into a document. At least one intermediate format document data described in an intermediate format expression obtained as a result of the semantic analysis is stored, and the document reading unit stores
Intermediate format document data corresponding to the document identification information is read from the intermediate format storage means, and the target language document generation means is described in the language corresponding to the requested language information from the intermediate format document data read by the reading means. The generated document data is generated, and the document transmission unit transmits the document data generated by the target language document generation unit to the client device.

In the server device, the original document input means inputs document data described in a predetermined language, the original document analysis means analyzes the input document data, and analyzes the result of the analysis of the document data. Intermediate format document data is generated, and the generated intermediate format document data is stored by the intermediate format storage unit. Further, in the analysis of the original document analysis means, when a plurality of analysis results are generated due to the ambiguity of the document data to be analyzed, the analysis result display means displays them.

As described above, a desired description language can be specified from the client, and the document data described in the natural language can be generated from the document data stored in the form of the intermediate format document data in accordance with the desired description language, and can be output by the client device. It is possible to browse document data written in a desired language without storing document data described in a number of languages on a server device or installing a language translation program on a client device. Further, since the intermediate format document data is generated from the document data described in the natural language, the intermediate format document data can be easily created. Furthermore, when the document data described in the natural language is ambiguous, the analysis result is displayed, so that it is possible to determine whether the intermediate format document data is desirable or not.

Further, in the multilingual communication system according to claim 2, in the server device, the analysis result determination means selects a specific analysis result from the plurality of analysis results displayed by the analysis result display means, and performs the analysis. Confirm as a result.

As described above, when the document data described in the natural language is ambiguous, the analysis result can be selected, so that desirable intermediate format document data can be created.

Further, in the multilingual communication system according to the third aspect, the analysis result display means is a parse tree display means, and the document data input by the original document input means is used as a parse tree as an analysis result. Is displayed.

As described above, when the document data described in the natural language is ambiguous, the analysis result is displayed by the syntax analysis tree. Therefore, the user can easily recognize the analysis result by looking at the display. be able to.

Next, a basic processing flow between the server apparatus 102 and the client apparatus 103 will be described with reference to FIG. First, the client device 103 performs a process of inputting instruction information of desired document data (S401 and S indicate steps, and the same applies hereinafter). Next, the address of the server device, which is information for uniquely determining the server device where the document data is located on the communication network, is acquired from the input instruction information (S402). In the present embodiment, TCP / IP (Transmission Control Protocol) is used as the address of the server device.
ol / Internet Protocol) or I
Although the P address is used, any other information that can determine an address on the communication network may be used.
Next, the document identification information, which is the instruction information of the document data in the server device, is determined from the desired document data instruction information (S403). Next, information on a request language that specifies which natural language is used to describe the desired document data is determined (S404).

Next, the determined document identification information and the requested language information are transmitted to the server at the address determined in S402 (S405). In the present embodiment, as a transmission method to the server device, HTTP (Hyper Text Transfer) over TCP / IP is used.
Protocol). Specifically, the client device transmits data in the format shown in FIG. 5A to the server device. "GET" means a data request, and <document identification information> specifies the document identification information determined in S402. <Version information> specifies HTTP version information, and <CRLF
> Indicates a new line character. <Various header information> is HTTP
Specify the header information specified in as required. "A
ccept-Language: "is a character string indicating that the requested language information follows, and <required language> specifies a predetermined character string for identifying the requested language. FIG. This is an example when the information is "/pub/sample.html", the HTTP version is 1.0, and the requested language is Japanese.
Since TCP / IP and HTTP are well-known technologies that have already been widely put into practical use, descriptions thereof will be omitted.

The server device receives the document identification information of the requested document and the requested language information transmitted from the client device in S405 (S408), and generates desired document data in a desired natural language based on the received information. In order to do so, a document data generation process is executed (S409). Details of S409 will be described later. If the desired document data in the desired natural language cannot be generated in S409, it is determined as an error (S410).
In the present embodiment, this error is determined by referring to an error flag described later. If there is no error, the generated document data is transmitted to the client (S411), and if there is an error, error information is transmitted (S412). The client receives document data or error information from the server
(S406), it is displayed on the display device (S407).

Next, details of the document data generation processing (S409) will be described with reference to FIG. First, in order to store an error state, an error flag (not shown) formed in the work memory 203a is cleared to set an error-free state (S601). Next, the presence or absence of the document data specified by the document identification information is determined (S602). If the corresponding document data does not exist in the server device (S602: No), the process proceeds to S607 to generate an error. If there is (S602:
Yes), the process proceeds to S603. In S603, the document management program searches the intermediate format document data storage unit 203d for the intermediate format document data specified by the document identification information transmitted from the client, and reads it into the work memory 203a.

In the present embodiment, the intermediate format document data stored in the intermediate format document data storage unit 203d is such that each intermediate format document data corresponds to one file, and a document identification designating the document data. As the information, a file name containing the intermediate format document data is used. In this case, the determination in S602 is made based on whether a file having the file name indicated by the document identification information exists, and in S603, the document management program reads the data of the file into the work memory 203a. In addition,
In addition to using the file name as the document identification information, a database management program can be used as the document management program, the storage area of the database can be associated as the intermediate format document data storage unit 203d, and the document data in the database can be specified as the document identification information Instruction information may be used.

Next, it is determined whether or not the read intermediate language format document data can be translated into a target language based on the requested language information received in S408 (S604). In the present embodiment,
As described above, since there is an individual target language document generation program for each target language, is the target language document generation program corresponding to the requested language information received in S408 stored in the target language document generation program storage unit 202b? Whether or not
The determination of S604 is performed.

In step S605, target language document generation processing for generating target language document data from the read intermediate format document data is executed. Details of S605 will be described later. In S606, S6
The target language document data generated in 05 is temporarily stored in the generated document memory 0203b for transmission. In S607, S602
And the determination in S604, an error flag is set for error processing, and the error state is stored.

Next, the details of the processing of the intermediate format document data creation program which is the main body of the document analysis means of the present invention will be described with reference to FIGS. 7, 8 and 9. First, the input unit 206 inputs document data described in a predetermined natural language.
(S701). The input document data is temporarily stored in the original document memory 20.
It is stored in 3c (S702). This document data is processed as original document data. The original document data is first subjected to morphological analysis processing (S703). In S703, the original document data is divided into morphemes, converted into a morpheme string, and the part of speech of each morpheme is determined with reference to the morphological analysis dictionary stored in the translation dictionary storage unit 202e. As an example of generating intermediate format document data from Japanese, if the original document data is as shown in FIG. 8A, a morphological analysis result including a morphological sequence as shown in FIG.

Next, a syntax analysis process is performed (S704). In S704, to the morpheme string including the part of speech information analyzed in S703, the syntax rule data stored in the translation dictionary storage unit 202e, and apply the information of the syntax analysis dictionary, and analyze the modification relationship between each morpheme, Determine the semantic role of the case and form a parse tree. For example, a morphological analysis result as shown in FIG.
A parsing result consisting of the parsing tree shown in FIG. 8C is obtained. Where "S" is a sentence, "NP" is a noun phrase, and "AD
“V” represents an adverb, and “VP” represents a verb phrase.

Next, it is determined whether or not the original document data has ambiguity (S705). Specifically, the parsing process (S70
If a plurality of parse trees are formed in 4), it is determined that there is ambiguity in the original sentence data, and if not, that is, if only one type of parse tree is formed, there is no ambiguity. to decide. For example, since the parse tree formed from the original document data shown in FIG. 8A is of one type shown in FIG. 8C, in S705, it is determined that the original sentence has no ambiguity.
Then, the process proceeds to a dependent structure analysis process (S706).

On the other hand, the example sentence shown in FIG. 10 is ambiguous whether “beautiful” modifies “girl” or “girl's mother”. When such ambiguous original document data is input, in the syntax analysis processing (S704), FIG.
Two types of parse trees shown in (a) and (b) are formed. (Note that the parsing tree shown in FIG. 11 does not need to indicate sentences, phrases, and parts of speech because the difference between the parsing results should be clear.) In the case where a plurality of parsing trees are formed as described above. , S7
In 05, it is determined that the original text has ambiguity, and analysis candidate display (S
708). The analysis candidate display is a process performed by the intermediate format creation program which is the main component of the analysis result display means of the present invention. Specifically, the parse tree shown in FIG. 11 is displayed on the monitor 208 as a result a and a result b, respectively. Next, analysis result confirmation processing (S709) is performed. The analysis candidate display is a process performed by the intermediate format creation program which is the main body of the analysis result determination means of the present invention.

Specifically, based on an instruction input by the operator of the server device to the input unit 206, it is determined which of the result a and the result b has been selected, and the analysis result is determined. Then, the process proceeds to a dependent structure analysis process (S706).

In this embodiment, analysis candidates are displayed using a syntax parse tree. However, as shown in FIG. 12, parentheses may be added to original document data to display analysis candidates.

Next, a dependent structure analysis process is performed (S706). S7
In 06, a dependency structure is formed based on the parse tree that is the analysis result of S704. When the dependency structure analysis process is performed on the syntax analysis result of FIG. 8C, a dependency structure as shown in FIG. 9A is obtained. Here, "PRED" replaces the predicate with "NO
"M" indicates a dependent structure noun phrase, and "ADV" indicates an adverb. Next, the data of the dependency structure obtained in S706 is stored in the intermediate format document data storage unit 203d (S707).

In the present embodiment, the expression of the dependency structure of a sentence is used as an intermediate form expression, and data representing the semantic content of the sentence expressed by the dependency structure, which is obtained as a result of analyzing the sentence as described above, It is used as formal document data. Specifically, it is stored as a set of structural elements 1305 as described in FIG. Each structural element 1305 has four items of a structure type 1301, case information 1302, a dictionary pointer 1303, and the number of dependent structures 1304. The structure type 1301 stores a type such as a predicate or a noun phrase as a flag. Case information
Reference numeral 1302 stores case type information such as a nominative case, a purpose case, or a form as a flag as necessary. Dictionary pointer
Reference numeral 1303 stores a pointer to dictionary data containing word information corresponding to the structural element. Dependent structures
1304 stores how many structuring elements directly depend on the structuring element. It should be noted that the number of dependent structures 1304 further depends on the structural elements that are dependent on the structural element, that is, does not include the number of indirectly dependent elements as nests.

For example, when the dependency structure shown in FIG. 9A is stored, the data becomes as shown in FIG. 13B. Here, “K1” represents the nominative case, “K2” represents the purpose case, and “K3” represents the form case. The dictionary pointer indicates the number 1306 of the dictionary data illustrated in FIG. The dictionary data includes words 1307 in the language used in the original document, their parts of speech 1308, and corresponding words 1309 in other languages,
Various grammatical information and the like are stored. FIG. 13C shows an example in which the other language is English. In addition, as the intermediate format document data, in addition to the above-described method, an artificially defined readable language (hereinafter, referred to as a common language) is used as the intermediate format expression, and the document data described in the language is converted into the intermediate format. It may be used as document data. For example, a sentence described in an artificially designed language as disclosed in Japanese Patent Application Laid-Open No. 6-325080 may be used as the intermediate format document data.

Next, the details of the target language document generation processing in S605 will be described using FIG. 14 and FIG. The target language document generation process is a process performed by a target language document generation program which is a subject of a target language document generation unit of the present invention. First,
A syntax generation process is performed on the intermediate format document data read into the work memory 203a in S603 (S1401). In the syntax generation processing, a syntax tree of the target language is generated based on the dependency structure described in the intermediate format document data while referring to the generation rule data, and the word order is determined. Next, morpheme generation processing is performed (S1402), and the ending of the word is changed as necessary,
The generation of the generated document data is completed. To give an example in which the target language is English, when a sentence having a dependency structure shown in FIG. 9A is subjected to a syntax generation process and a morpheme generation process, a sentence as shown in FIG. 9B is obtained. The target language document generation result is obtained. Where "PRON" is a pronoun,
"V" indicates a verb, "ART" indicates an article, and "N" indicates a noun.

In the present embodiment, the dependency structure data stored as the intermediate format document data is directly input to the syntax generation processing. However, the dependency structure conversion processing is performed before the input to the syntax generation processing. May go. Specifically, instead of using the dependency structure of the sentence stored in the intermediate format document data as it is, a dependency structure conversion process corresponding to the intermediate format conversion means is performed and converted into a dependency structure corresponding to the target language. Then, it is input to the syntax generation processing.

Each of the morphological analysis processing, syntactic analysis processing, dependency structure analysis processing, syntax generation processing, and morphological generation processing according to the present embodiment is described in Japanese and English by the Electronic Technology Research Institute and Kyoto University. This is a well-known technique disclosed in "Research on a Bulletin System for Science and Technology Literature-Report on Development of Language Processing System" and JP-A-62-203273.

As is apparent from the above description,
The multi-language communication system according to claim 1 of the present invention,
A client can specify a desired description language, and can generate document data described in a natural language from document data stored in the form of intermediate format document data in accordance with the desired description language and output the document data in a client device. It is possible to browse the document data described in a desired language without saving the document data described in the above and without installing a language translation program in the client device.
Further, since the intermediate format document data is generated from the document data described in the natural language, the intermediate format document data can be easily created. Furthermore, if the document data described in natural language is ambiguous, the analysis result is displayed,
It can be determined whether the intermediate format document data is desirable.

Further, in the multilingual communication system according to the second aspect, when the document data described in the natural language is ambiguous, the analysis result can be selected, so that desirable intermediate format document data can be created.

Further, in the multilingual communication system according to the third aspect, when the document data described in the natural language is ambiguous, the analysis result is displayed in a syntax analysis tree, so that the analysis result can be easily obtained. Can be recognized.
