Abstract

PURPOSE:To form, edit and retrieve a data base through the use of a user- oriented language by regarding a command language operating the data base as an intermediate language in a machine translation function and executing the conversion between the user-oriented language and the intermediate language. CONSTITUTION:The machine translation function converts the user-oriented access language into the command language 11 through a character input part 21, a morpheme analyzing part 22, a construction analyzing part 23, and a meaning analyzing part 24 with the aid of a dictionary used for the mutual conversion between the user-oriented access language and the command language. On the other hand, an output from the data base side is converted into the user-oriented language through a meaning synthesizing part 240, a construction synthesizing part 230, a morpheme synthesizing part 220, and a character output part 210, and is outputted to a user terminal. Thereby users can make access to the data base by using the familiar language.

1.1, which specifically relates to a database management device that allows the same database to be accessed and used from user terminals using different languages.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional device. This diagram corresponds to, for example, the diagram shown on p. 71 of "Database Theory" by Hiroshi Arisawa, published by Information Processing Society of Japan in 1980, and in the diagram (1) is a database A management device, (2) a database, and [31, +41 U, respectively, user terminals. Among the components of the database management device (1), (11) is a command language section, (12) is a database management system (hereinafter abbreviated as DBMS) program,
(13) This is a fl operating system (hereinafter abbreviated as O8) program. User terminal +31, +
Reference numeral 41 includes a keyboard for inputting all data into the database management device 1 il+, and a CRT display device for displaying the input data and data output from the database management device (1).

Next, cutting will be explained. . When inputting all data to the database (2) or retrieving all data stored in the database (2) and searching/editing it, use the command specified in the command language section (11) on any user terminal. It must be done using language. In other words, the command language defined in the command language section (11) is a language specific to the system designed to use this database (2), and in the conventional device, the command language defined in the command language section (11) is unique to the system designed to use this database (2). No matter what nationality a person is trying to perform any kind of processing, the Kfl that accesses this database (2) must use this command language. The DBMS (12) accesses the database (12) based on a database access command expressed in a command language.
2) This is the entire program that operates directories and tables for administrative purposes, and the entire program that performs output operations for the database (2) as a 08(13)U large-capacity file device.

[Problem that the invention seeks to solve]

Since conventional devices are configured as described above, all users of the database must use the command language unique to the system 1, regardless of their nationality or the M language used (I+1). It is necessary to learn everything in detail, and technical knowledge related to computers and databases is often required.If a database is to be made widely available to the public, it is necessary to use a command language specific to the database management device. This invention was made to solve the above-mentioned problems, and allows users of the database to fully access the database using the language they are accustomed to using on a daily basis. It is an object of the present invention to provide a database management device that can simultaneously access the same database from a number of user terminals that use different languages.

[Means to solve all problems]

The device of this invention is equipped with a machine translation function that performs mutual conversion between each user access language input from a plurality of user terminals and a command language for using this database. We designed this so that users can access the database using the language they are accustomed to using on a daily basis.

[Effect]

The machine translator of this invention also has a dictionary for performing mutual conversion between the user access language and the command language. Since the electric wire translation mechanism is equipped with a group of dictionaries that say these words @), it is accessed by the publisher through the Character Human Power Department, Sugi ■ Element Analysis Department, Syntax Analysis Department, and Semantic Analysis Department. 100 words are converted into command M words, and on the other hand, the output from the database side is converted into user words via the syntax, syntax synthesis, morphological synthesis, and character output sections, and its use. output to the user terminal.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. IIIVC.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 3 indicate the same or corresponding parts, and (

When input from a specific user terminal (temporarily referred to as terminal (3)) in the language used by that terminal (3) is input to the correspondence table (20) via the switching function f61 k, the correspondence table (20) commands (27) to select a dictionary corresponding to this language from the dictionary group (26).

The user access language input via the switching function 161f is temporarily stored in the buffer of the character input section (21) and sequentially processed. The morphological analysis unit 22) is responsible for recognizing and extracting various parameters related to the shape of words, and for languages such as Japanese and Japanese, dividing sentences into word units. The syntactic analysis unit (23) uses the grammatical information to determine the structure of the sentence. For example, Greibach normal form
An analysis algorithm based on a context-free grammar expressed as rm:GNF) can be used. The semantic analysis unit (24) extracts background elements related to database operations. The context analysis unit (25) analyzes various contexts related to database operations. Information necessary for the processing in each of the sections (22) to (25) above can be obtained by referring to a dictionary connected by a switch mechanism (edict).

This dictionary contains words (part of speech, conjugation, gender, number, case, idiom,
Information such as semantic parameters, translations, translation rules, and language correspondence table between the user language and the database command language are listed in an easy-to-reference format. For example, when referring to a headword in the word section of a dictionary,
Use a method such as displaying the first letter sound of a word and placing a pointer at the location of the file that begins with that letter.

As described above, the user language input from the user terminal (3) is converted into a command language for database operation by the machine translation function (10), and the command language section (10) is converted into a command language for database operation.
It is temporarily stored in the buffer of 1) and operates on database (2) under the control of DBMS (12) and 08 (13).

The response from the database (2) side is expressed in a command language format, and this is sent to the context synthesis unit (250).
