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 provider of the document data and a viewer of the document data Often the native language is different from the 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 installed in a client device, in order to translate and display all sentences in various languages provided by each server,
It is necessary to mount a large number of language translation programs capable of translating each language into a desired language on the client device. 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, as proposed in Japanese Patent Application No. 8-322842 filed by the present applicant, document data stored in a server device is not a document data described in a natural language. The document data described in natural language is grammatically and semantically analyzed and stored as intermediate format document data. 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 has been proposed.

However, in the multilingual communication system proposed above, a program for generating document data described in a desired natural language (hereinafter referred to as a target language) from intermediate format document data (hereinafter referred to as a target language document). The problem is that it takes a long time to generate a target language document in response to a request from a client device and send the document to the client device. Was.

Next, a basic processing flow between the server device 102 and the client device 103 will be described with reference to FIG. First, the client device 103 performs input processing of request information of desired document data (S401). 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 this embodiment, TCP / IP (Transmiss
ion Control Protocol / Internet Protocol).
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 data request, <document identification information>
Specifies the document identification information determined in S402. <Version information> specifies HTTP version information, and <CRLF>
Indicates a newline character. For <various header information>, specify the header information specified by HTTP as necessary. "Acc
ept-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. 5B shows document identification. This is an example where the information is "/pub/sample.html", the HTTP version is 1.0, and the requested language is Japanese.
P / IP and HTTP are well-known technologies that have already been widely put into practical use, and a description 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, the 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). Then, in S602, the original document data determination program determines whether the document data specified by the document identification information and described in the request language exists in the original document data storage unit 203e (S602). If the document data exists in the server device (S602: Yes), the process proceeds to S608 to read out the document data.
2: No), the process proceeds to S603.

In the present embodiment, the original document data stored in the original document data storage unit 203e is a file of the original document data upon generating the intermediate format document.
As document correspondence information for identifying the original document data, document identification information, which is a file name containing the intermediate format document data generated from the original document data, and a description language name of the original document data are additionally stored. Have been. FIG. 7A shows a data structure of data stored in the original document data storage unit 203e. For the document data requested in FIG. It is stored as in b). "/Pub/sample.html" which is the file name of the intermediate language file is used as the document identification information, and "jp" representing Japanese is used as the description language name of the original document data in the field of the document correspondence information. Contains original document data described in Japanese, which was used when the intermediate language file "/pub/sample.html" was generated.

Then, the original document data judgment program
It is determined in S602 whether or not data having the file name specified in the document identification information and the requested description language name in the document correspondence information exists in the original document data storage unit 203e, and it is determined that the data exists. In this case, in S608, the original document reading program reads the document data portion into the generated document memory 203b.

In S603, it is determined whether or not the document data specified by the document identification information exists in the intermediate format document data storage unit 203d. If the corresponding document data does not exist in the server device (S603: No ), The process proceeds to S609 to generate an error, and if there is an error (S603: Yes), the process proceeds to S604. In S604, the document management program searches the intermediate format document data storage unit 203d for the intermediate format document data designated 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
It is assumed that one file corresponds to one file, and that the file name storing the intermediate format document data is used as the document identification information for specifying the intermediate format document data. In this case, it is determined in step S603 whether or not a file having the file name indicated by the document identification information exists. In step S604, the document management program stores the data of the file in the work memory 203a.
Will be read.

In addition to the method using the file name as the document identification information, a database management program is used as the document management program, and the intermediate format document data storage unit 20 is used.
The storage area of the database may be associated with 3d, and instruction information capable of specifying document data in the database may be used as document identification information.

Next, it is determined whether the read intermediate language format document data can be translated into a target language based on the requested language information received in S408 (S605). In the present embodiment, as described above, since each target language has a separate target language document generation program, the target language document generation program corresponding to the requested language information received in S408 is The determination in S605 is made based on whether or not the generated program is stored in the generated program storage unit 202b.

In S606, target language document generation processing for generating target language document data from the read intermediate format document data is executed. Details of S606 will be described later. In S607, S606
Is temporarily stored in the generated document memory 203b for transmission. In S609, S603 and S6
In response to the determination at 05, an error flag is set for error processing and the error state is stored.

In S608, the original document reading program executes
The data having the file name as the document identification information and the language name of the request language in the document correspondence information is stored in the original document data storage unit 203e.
And reads the document data portion from the data into the generated document memory 203b. When the process proceeds to S608, there is no need to perform the target language document generation process of S606, which takes a long time, so that the document data generation process of S409 can be executed in a short time. The time from when the request from the device 103 is received until when the data of the generated document is transmitted in S411 can be reduced.

Next, details of the processing of the intermediate format document data creation program which is the main body of the original document analysis means of the present invention will be described.
This will be described with reference to FIGS. 8, 9 and 10. First, the input section
From 206, document data described in a predetermined natural language is input (S801). The input document data is temporarily stored in the original document memory 203c (S802). This document data is processed as original document data. The original document data is first subjected to a morphological analysis process (S803). In S803, the translation dictionary storage unit
Referring to the morphological analysis dictionary stored in 202e, the original document is divided into morphemes, converted into a morpheme string, and the part of speech of each morpheme is determined. As an example of generating intermediate format document data from Japanese, if it is the original document shown in FIG. 9A, a morphological analysis result composed of a morphological sequence as shown in FIG.

Next, a syntax analysis process is performed (S804). In S804, the morpheme sequence including the part-of-speech information analyzed in S803 is applied with the syntax rule data stored in the translation dictionary storage unit 202e and the information of the syntax analysis dictionary to analyze the modification relationship between the morphemes and , Determine the semantic role of the case, and form a parse tree. For example, a morphological analysis result as shown in FIG. 9B obtains a parsing result composed of the parse tree shown in FIG. 9C. Here, “S” represents a sentence, “NP” represents a noun phrase, “ADV” represents an adverb, and “VP” represents a verb phrase. Next, a dependency structure analysis process is performed (S805). In S805,
A dependency structure is formed based on the parse tree that is the analysis result of S804. When a dependency structure analysis process is performed on the syntax analysis result of FIG. 9C, a dependency structure as shown in FIG. 10A is obtained. Here, “PRED” represents a predicate, “NOM” represents a dependent structure noun phrase, and “ADV” represents an adverb.

Next, the data of the dependency structure obtained in S805 is stored in the intermediate format document data storage unit 203d (S806). S807
In the original document data writing program, the document identification information, which is the file name of the intermediate format document data stored in the intermediate format document data storage unit 203d in S805, and the description language name of the original document as document correspondence information, Memory 203c
In addition to the original document data stored in the
Store it in 203e.

In the present embodiment, an 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, is converted into an intermediate form. It is used as formal document data. Specifically, it is stored as a set of structural elements 1105 as shown in FIG. Each structural element 1105 has four items of a structure type 1101, case information 1102, a dictionary pointer 1103, and the number of dependent structures 1104. The structure type 1101 stores a type such as a predicate or a noun phrase as a flag. Case information
Reference numeral 1102 stores case type information such as a nominative case, a purpose case, or a form as a flag as necessary. Dictionary pointer
Reference numeral 1103 stores a pointer to dictionary data containing information on a word corresponding to the structural element. Dependent structures
1104 stores how many structural elements directly depend on the structural element. It should be noted that the number of dependent structures 1104 further depends on the structural elements that are dependent on the structural element, that is, does not include the number of elements that are indirectly dependent as nests.

For example, when the dependency structure shown in FIG. 10A is stored, the data becomes as shown in FIG. 11B. Here, “K1” represents the nominative case, “K2” represents the purpose case, and “K3” represents the form case. The dictionary pointer indicates the dictionary data number 1106 illustrated in FIG. 11C. The dictionary data stores a word 1107 in the language used in the original document, its part of speech 1108, a corresponding word 1109 in another language, and various grammatical information. In FIG. 11 (c),
This is an example when another language is English. The intermediate format document data may be a text described in an artificially designed language as disclosed in Japanese Patent Laid-Open No. 6-325080.

Next, the details of the target language document generation processing in S605 will be described with reference to FIGS. 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, syntax generation processing is performed on the intermediate format document data read into the work memory 203a in S603 (S1201). 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, a morpheme generation process is performed (S1202), and the ending of a word or the like is changed as necessary, thereby completing the generation of the generated document data. As an example in which the target language is English, if the syntax generation process and the morpheme generation process are performed on the sentence having the dependency structure shown in FIG. The target language document generation result is obtained. Here, “PRON” represents a pronoun, “V” represents a verb, “ART” represents an article, and “N” represents a noun.

In this 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,
In the multilingual communication system of the present invention, when document data is input to the server device and converted into intermediate format document data, the input document data is stored in the original document data storage unit. Then, when a document is requested from the client device in the same natural language as the description language of the original document data,
By reading and transmitting the document stored in the original document data storage unit, the target language document generation processing can be omitted, and the document can be transmitted in a short time after receiving a request from the client device.
