DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a server device capable of providing document data in a desired language by having a translation function and a client device capable of displaying the document data via a communication network. The present invention relates to a multi-language compatible communication system which is connected by a connection.

[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. 11, document data described in various languages such as English, Japanese, and Chinese is stored in each server device 1102. The client device 1103 connected to the server device via the communication network 1101 can display 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 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 will increase 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.

However, the following problems still remain in the multilingual communication system proposed above.

In order for a user of a multi-language communication system to search for desired document data from a plurality of intermediate format document data stored in the server device, the server device must use all of the intermediate format document data. It was necessary to generate document data described in a natural language. Further, the user needs to sequentially refer to the contents of all the generated document data to determine whether or not it is necessary.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and a multilingual communication system capable of easily searching for desired document data from intermediate format document data stored in a server device. It is intended to provide.

[0012]

In order to achieve the above object, according to the present invention, there is provided a multilingual communication system, comprising: a client device; and a search result in response to a search request from the client device. To the client device. In the client device, the search request transmitting unit transmits a search request including a search character string and search language information indicating a description language of the search character string to the server device, and the search result receiving unit transmits the search result to the server device. The search result is received, and the search result output means performs output processing such as display output, print output, and voice output as the search result received by the search result receiving means.

On the other hand, in the server means, the search request receiving means receives the search request from the client device, and the intermediate format document storage means stores at least one document data,
A document described in a natural language is stored as intermediate format document data described in an intermediate format expression obtained as a result of grammatically and semantically analyzed, and a search character string conversion unit stores the search language included in the search request. According to the information, the search character string is converted into an intermediate format search character string described in the intermediate format expression, and the intermediate format search unit performs the intermediate format search from the intermediate format document data stored in the intermediate format document storage unit. An intermediate format document data including a character string is searched, and the search result is sent to the client device by the document sending unit.

As described above, a client can specify a search character string described in a desired language, thereby searching for desired document data from document data stored in an intermediate format document data format, and transmitting the search result to the client. Since the data can be output by the device, it is possible to easily search for the document data in a desired language without storing the document data described in many languages in the server device and without installing a language translation program in the client device. .

In the multilingual communication system according to the second aspect, in the server device, the target language document generating means may convert the intermediate format document data searched by the intermediate format searching means into the search language information. The document data described in a corresponding language is generated, and the search result transmitting unit transmits the document data generated by the target language document generating unit to the client device as a search result.

As described above, since the document data described in the natural language in which the search character string is described is obtained as the search result, the document data of the search result can be referred to immediately.

Further, in the multilingual communication system according to the third aspect, in the client device, the search request transmitting means transmits a search request including target language information in addition to the search character string and the search language information. In the server device, the search request receiving unit receives the search request, and the target language document generation unit corresponds to the target language information from the intermediate format document data searched by the intermediate format search unit. Generate document data described in the language.

As described above, since the document data described in the natural language indicated by the target language information is obtained as the search result, the search result can be referred to in the desired natural language.

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 inputs an address of the server device, which is information for uniquely determining a server device to be searched on the communication network (S401). In this embodiment, TCP / IP (Tra
Although a host name or an IP address specified by an nsmission control protocol / Internet Protocol is used, any other information that can determine an address on a communication network may be used. Next, a search character string that is considered to be included in the desired document data and a natural language that describes the search character string are specified. The search language information and the natural language in which the search result document data is described are specified. The target language information to be input is input (S402).

Next, a search request including the input search character string, search language information, and target language information is transmitted to the server device at the address input in S401 (S403). In the present embodiment, the transmission method to the server
It is assumed that HTTP (Hyper Text Transfer Protocol) is extended and used. Specifically, the client device transmits data in the format shown in FIG. 5A to the server device. "SEARCH" means a search request, and <CRLF> indicates a carriage return / line feed character. "K
ey-Word: "is a character string indicating that a search character string follows, and <search character string> specifies the search character string input in S402." Key-Language: " Next, it is a character string indicating that the search language information follows, and <search language> specifies a predetermined character string that identifies a natural language that describes the search character string, and “Accept-Language: "Is a character string indicating that the target language information follows, and <target language> specifies a predetermined character string for identifying the target language.

FIG. 5B shows an example in which Japanese of "apple" as a search character string is set as a search language and English is set as a target language. Note that the above-described TCP / IP and HTTP are well-known technologies that have already been widely put into practical use, and thus description thereof will be omitted.

The server receives the search character string, search language information, and target language information of the search request transmitted from the client in step S406, and executes an intermediate expression search process to perform a search based on the received information. Yes (S407). S407
Will be described later. If the desired search result is not obtained in S407, it is determined as an error (S408). In the present embodiment, this error is determined by referring to an error flag described later. If there is no error, the search result is transmitted to the client (S409). If there is an error, error information is transmitted (S410). The client receives the search result or error information from the server (S404) and displays it on the display device (S405).

Next, details of the intermediate expression search 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, it is determined whether or not it is possible to generate a target language based on the target language information received in S406 from the intermediate language format document data as a search result (S602). 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 target language information received in S406 is stored in the target language document generation program storage. The determination in S602 is performed based on whether or not the information is stored in the unit 202d. If it is determined that generation is not possible (S602: No), the process proceeds to S610 to make an error, and if it is determined that generation is possible (S602: Yes), the process proceeds to S603.

In S603, it is determined whether or not the search character string can be converted into an intermediate expression based on the search language information received in S406 (S603). In the present embodiment, as described above, since there is an individual search character string conversion program for each search language, the search character string conversion program corresponding to the search language information received in S406 is stored in the search character string conversion program storage unit.
The determination in S603 is performed based on whether or not it is stored in 202b. If it is determined that the conversion is not possible (S603: No), the process proceeds to S610 to make an error, and if it is determined that the conversion is possible (S60
3: Yes), the process proceeds to S604. In S604, the search string
It is converted to an intermediate format based on the search language information received in S406. The conversion process to the intermediate format is a process performed by a search character string conversion program which is a main component of the search character string conversion means of the present invention, and details thereof will be described later. If the conversion in S604 fails (S605: No), the process proceeds to S610 to make an error, and if successful, the process proceeds to S606.

Next, in S606, based on the intermediate format document data stored in the intermediate format document data storage unit, intermediate document data including the search character string converted into the intermediate format in S604 is searched. The search processing of the intermediate format document is a process performed by an intermediate format document search program which is a main body of the intermediate format search means of the present invention, and details thereof will be described later. As a result of this search, if intermediate document data including the search character string is found, the process proceeds to S608, and if not found, the process proceeds to S610 to generate an error.

Next, in S608, target language document generation processing for generating target language document data according to the target language information received in S406 from the intermediate language format document data obtained as a result of the search in S606 is executed. Details of S608 will be described later. In S609, S6
The target language document data generated in 08 is temporarily stored in the generated document memory 203b for transmission. In S610, S602,
Upon receiving the determinations in S603, S605, and S607, an error flag is set to perform error processing, and the error state is stored.

Next, details of the intermediate format document data will be described with reference to FIGS. 8, 9 and 10. The intermediate language document data is obtained as a result of morphological analysis, syntax analysis, and structural analysis of document data described in a natural language (hereinafter, referred to as original document data). The original document data is first subjected to morphological analysis. The morphological analysis refers to a morphological analysis dictionary, divides an original document into morphemes, converts them into a morpheme sequence, and determines the part of speech of each morpheme. As an example of generating the intermediate format document data from Japanese, if the original document is as shown in FIG. 8A, a morphological analysis result including a morphological sequence as shown in FIG. 8B is obtained by morphological analysis.

Next, syntax analysis is performed. In the parsing, the morphological sequence including the part-of-speech information obtained by the morphological analysis includes
The parsing dictionary is applied to analyze the modification relation between each morpheme, determine the semantic role of the case, and form a parsing 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,
Perform dependency structure analysis. In the structural analysis, a dependency structure is formed based on a parse tree that is a result of parsing. FIG.
When the dependency structure analysis is performed on the syntax analysis result of (c), a dependency structure as shown in FIG. 9A is obtained. here,
"PRED" is a predicate, "NOM" is a dependent structure noun phrase, and "AD
"V" represents an adverb.

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 will be used as formal document data. Specifically, it is stored as a set of structural elements 1005 as shown in FIG. Each structural element 1005 has four items of a structure type 1001, case information 1002, a dictionary pointer 1003, and a dependent structure number 1004. The structure type 1001 stores a type such as a predicate or a noun phrase as a flag. Case information
Reference numeral 1002 stores case type information such as a nominative case, a purpose case, or a form as a flag as necessary. The dictionary pointer 1003 stores a pointer to dictionary data containing information on a word corresponding to the structural element. The dependent structure number 1004 stores how many structural elements directly depend on the structural element. Note that the number of dependent structures 1004 further depends on the structural element that depends on the structural element, that is,
It 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. 10B. Here, “K1” represents the nominative case, “K2” represents the purpose case, and “K3” represents the form case. The dictionary pointer indicates the number 1006 of the dictionary data illustrated in FIG. The dictionary data includes words 1007 in the language used in the original document, their parts of speech 1008, and corresponding words 1009 in other languages,
Various grammatical information and the like are stored. FIG. 10C illustrates 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 process of converting the search character string into the intermediate format in S604 will be described with reference to FIG. In the present embodiment, the expression of the dependency structure of the sentence described above is used as the intermediate format document data. Therefore, a search character string is searched in a dictionary (FIG. 10C) containing word information, and a pointer to the matched dictionary data is an intermediate expression of the search character string. For example, when the search character string is “apple”, a pointer “003” to dictionary data in which “apple” is registered is an intermediate expression.

Next, the search processing of the intermediate format document in S606 will be described with reference to FIG. The search process for intermediate format documents
This is a process of selecting intermediate format document data including a search character string from the intermediate format document data stored in the intermediate format document data storage unit 203C. Then, the pointer to the dictionary data as a result of the intermediate representation of the search character string is the dictionary pointer 10 of the set of the structural elements 1005 corresponding to the intermediate format document data.
If any of 03 matches, the intermediate format document data is
It can be determined that the search string is included. For example, when the search character string “apple” is searched, FIG. 10B includes a pointer “003” to the dictionary data obtained by converting the search character string “apple” into an intermediate expression in S604 as a dictionary pointer. I have. Therefore, it can be determined that the intermediate language document data shown in FIG. 10B includes the search character string “apple”.

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,
A syntax generation process is performed on the intermediate format document data searched in S606 (S701). 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 (S702), and the ending of the word is changed as necessary, thereby completing the generation of the generated document data. As an example where the target language is English, FIG.
When the syntax generation processing and the morpheme generation processing are performed on the sentence having the dependency structure shown in (a), a target language document generation result as shown in FIG. 9B 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.
