Abstract

PURPOSE:To produce with high efficiency a data base corresponding to plural languages by using a conversion table which produces plural key words with key input of one time. CONSTITUTION:At production of a data base for retrieval of information, a 1st key word received from an input device 1 is converted into a 2nd key word by a conversion table 2. The table 2 can convert a certain character string into another one having the same meaning, e.g., the conversion between Roman characters and KANJI (Chinese characters) and KANJI and English characters. Both 1st and 2nd key words are stored in a control table 5 in relation to the specific data stored in an information memory. When the data base is retrieved, the types (Roman character, KANJI, etc.) of the key word used for retrieval of the data base are selected. Then the key word of the selected type is used for retrieval of the data base.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an information retrieval device, and in particular, it is possible to prepare keywords in a plurality of languages and select a keyword in any language from among them. The present invention relates to an information retrieval device for retrieving information.

[Conventional technology]

Conventionally, in many information retrieval devices, file names, search keywords, and file contents are often expressed in Japanese on systems that can handle Japanese, and in alphabetical characters on systems used in Europe and the United States. often expressed.

[Problem to be solved by the invention]

In recent years, with the mass production of optical discs that store large amounts of information, as typified by CD-ROMs,
It has been proposed to apply this as a medium for electronic publishing.

However, for example, if Japanese is used as the file name of a file recorded on the original disc, there is a possibility that the files on that optical disc will not be accessible on systems that do not support Japanese, such as Western systems. .

For example, encyclopedia and dictionary data were recorded (j)−
ROM and the like can be a common property of mankind, and it can be said that it is a problem that they can only be read under a system that supports a specific language.

SUMMARY OF THE INVENTION An object of the present invention is to provide an information retrieval device that can perform all file searches in multiple languages.

[Means to solve the problem]

In order to achieve the above object, the first invention of the present application provides an information retrieval device that searches for corresponding information in an information storage means using a keyword input from an input device.
A conversion table for converting the first type of keyword input from t into a second type of keyword, and a management table for associating the first and second type of keywords with the corresponding information. It is characterized by:

Further, the second invention of the present application provides an information retrieval device that searches for corresponding information in an information storage means based on a keyword inputted by an input device. A management table for associating the keywords with the corresponding information, and a selection means for selecting the type of the keywords to be used for information retrieval are provided, and information retrieval is performed using the types of keywords selected by the selection means. It is characterized by:

In the first and second inventions of the present application, the number of types of keywords is not limited to two, but may be six or more.

[Effect]

When creating a database for information retrieval, the first keyword entered from the input device is converted into the second keyword by the conversion table.
will be converted into keywords. That is, the conversion table converts a character string consisting of 1, ψ1j, such as from Roman characters to Kanji, or from Kanji to alphabet (English), to another character string having the same meaning. The first and second keywords are recorded in the management table in association with specific data within the information storage means.

When searching a database using the management table created in this way, the searcher first selects the type of keyword (Roman characters, Kanji, English, etc.) to be used for the search using the selection means. Thereafter, a search is performed using the selected type of keyword.

The present invention enables searchers to search for data in a language that can be processed by their own system or in a desired language.

〔Example〕

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

FIG. 1 shows an embodiment of the database creation system of the present invention. In the figure, 1 is an input device, 2 is a conversion table, and 5
is register A, 4 is register B15 is management table, 6
is a set of files stored in the information storage means, 7 is file A, and 8 is file B.

Each part will be explained below. The input device 1 is for inputting keywords, and the conversion table 2 is for converting the first keyword input from input bag #1 to generate a second keyword.

FIG. 2 shows an example of a conversion table. In this embodiment, keyword 1 is expressed in Japanese in Roman letters, and keyword 2 is expressed in Japanese. The format of the data is
Keyword 1 is ASCII, which expresses one character in one byte.
Code, keyword 2 is J, where 1 character is expressed in 2 bytes.
Represented by IS code.

The management table 5 in FIG. 1 manages a collection of keywords and files. A pointer in the management table 5 indicates the location where the file is stored. Further, keyword 1 and keyword 2 are associated with a pointer. The file set 6 is composed of a plurality of files. The file in this embodiment is data and images recorded on an optical disk, but is not limited to an optical disk, but may also be data recorded on any information storage means such as a disk or semiconductor memory. . Also,
The pointer in table 5 represents an address in a memory such as an optical disk, and data of a file corresponding to the keyword is stored at that address.

In this embodiment, as an example, it is assumed that the first file 7 stores solar data and the second file 8 stores moon data.

Next, the operation at the time of database creation will be explained with reference to FIG. In this embodiment, first, it is assumed that a set 6 of files storing information and a management table 5 in which file numbers and pointers are set are prepared.

A method for setting the first keyword and second keyword in the management table 5 will be explained with reference to the flowchart of FIG. Here, it is assumed that keywords for each file are set in ascending order starting from file number 1.

The keyword inputted from the input device 11 is registered as a first keyword in the keyword registration register 3, and is also sent to the conversion table 2 (Sl). Here, it is assumed that the input keyword is input in ASCII code. Conversion table 2 converts the first keyword input in ASCII code into a second keyword in Japanese. The relationship between the second keyword and the first keyword is a Japanese word and a Roman letter representing its pronunciation. Here, if "TAIYOU" is input as the first keyword, "sun" is selected as the second keyword (S2). The selected second keyword is stored in register 4. Thereafter, the first keyword stored in the register 3 and the second keyword stored in the register 4 are stored in the first row of the first keyword and second keyword items of the management table 5, respectively (S6).

By the above operations, the keywords attached to the first file 7 are stored in the management table 5VC.

Second. The above operations are repeated to define the keyword 'tiff' for the sixth file (S4).

Next, another embodiment of the present invention will be described with reference to FIG. In the figure, constituent elements 1 to 8 have the same contents as in FIG. 1, and therefore their explanations will be omitted.

In the figure, numeral 42 is a conversion table that stores the keywords of the three aphids. 43, 44, and 45 are registers for temporarily recording keyword A, keyword B, and keyword C, respectively. 46 is a management table for managing six types of keywords and file entities.

In the conversion table 42, keyword A, keyword B,
Three types of keywords are stored, keyword C.
In this embodiment, it is assumed that keyword A is stored in English, keyword B is a Japanese word with the same meaning as keyword A expressed in Roman letters, and keyword C is stored in Japanese expressed in JIS code.

The operation at the time of database creation will be explained with reference to FIG. Here, as in the first embodiment, it is assumed that a set 6 of files storing information and a management table 46 in which file numbers and pointers are set are prepared.

In this embodiment, it is assumed that keywords are input in English. It is also assumed that keywords corresponding to each file are set in ascending order starting from file number 1.

The keyword input from the input device 1 is stored in the register 43.
is registered as the first keyword A and sent to the conversion table 42. Here, it is assumed that the keyword is input as an English word. The conversion table 42 is A
From the keywords input as SCII codes, Japanese Roman keyword B and Japanese keyword C' in JIS code are selected. For example, if sun' is input as keyword A, keyword B will be "taiyou" and keyword C will be "sun".

Keyword B and keyword C selected in this way are registered in register 44 and register 45. Thereafter, the keywords registered in the registers 43 to 45 are stored in the keywords A, B, and C items of the management table 46.

By the above operations, the keyword attached to the first file is stored in the management table 46.

Second. The above operation is repeated to set the keyword for the third file.

Next, an embodiment of the data retrieval device will be explained with reference to FIG. In the figure, 1 is an input device, 52 is a keyword selection device,
46 is a management table, 6 is a collection of files, 7 is a first file, and 8 is a second file.

In the figure, the constituent elements indicated by numbers 1 to 46 have already been described, so their explanation will be omitted.

The keyword selection device 52 selects keywords to be used during a search from the keywords A, B, and C in the management table 46 in response to instructions from the input device 1.

This implementation sequence is a system for searching the database created in the second implementation sequence. It goes without saying that this system can also be applied to the first embodiment. When searching for data, the type of keyword used by the user is selected by giving an instruction to the keyword selection device 52 from the input device 1.

The keyword selection device 52 selects the keyword entry to be used on the management table 46 using software or hardware. For example, if the management table 46 is represented in an array, keyword selection can be achieved by reading all of a specific column.

In this embodiment, it is assumed that, for example, the management table 46 and the file set 6 are recorded on one original disk. If you try to read the above-mentioned optical disc on a computer system that does not support the Japanese JIS code, and if the keywords are written only in Japanese, that system will not be able to search by keyword, but other If a keyword is provided in Roman letters or English, it is possible to search using that keyword.

Therefore, it is possible to perform a search by selecting any desired keyword type from among English (keyword A), Roman alphabet (keyword B), and Japanese (keyword C).

〔Effect of the invention〕

According to the information retrieval device of the present invention, it is possible to create a database by generating multiple keywords with one keystroke, so it is possible to efficiently create a database that supports multiple languages. . Furthermore, when searching, it is possible to search using any type of keyword.
