Abstract

The present invention is to propose a method and apparatus for retrieving Hangul acronyms strings to simplify the input of keywords in Hangul search. In the comparison, the second character string of the Hangul keyword is input from the input device, is established as a keyword, and the data transition is made; In the data retrieval, a Korean target character string search method and apparatus for comparing a target Hangul data string by a search unit, and converting the input character string data corresponding to the keyword to compare with the keyword. According to the present invention, it is possible to easily enter and search only acronyms among Korean keyword strings, thereby achieving simplicity of Hangul search.

Description

Method and device for retrieving Hangeul Eum string

The present invention is to propose a method and apparatus for retrieving a Hangul consonant string that simplifies the input of keywords in the Hangul search.

In the present invention, the Hangul abbreviation string search refers to a keyword string input; Consonant string (first consonant string); For example, if the keyword string is 'Sejong the Great', it means a search that uses 'ㅅ ㅈㄷㅇ' as a search keyword.

Hangul acronyms on a computer Hangul keyboard are arranged so that you can easily type them at your fingertips without using a shift key. In the articles of patent application 96-40503, 96-47923 and Chosun Ilbo, page 16, November 16, 1996, Mr. Kwan-Hyun Cho and Korea Telecom entered Hangul to easily input Hangul as the tenkey of the phone. A compact keyboard is proposed.

As described above, a method of allowing Korean characters to be input from a tenkey of a telephone or a keypad of a simple portable communication device has been devised in an information process; Various types of Hangul input devices are expected to spread.

The ASCII code used in the computer is coded into 7 bits and arranged in sequence for each series to set '0' to bit 0x7 as shown in Table 1, so the program can identify the ASCII code from other types of characters or control commands through the bit mask. It can and can do character operations.

TABLE 1

ASCII code of the letter 'A' Identifier 'A' 7 bit code 7 6 5 4 3 2 One 0 0 One 0 0 0 0 0 One

On the other hand, Hangeul Ko combines Hangul code by assigning 5 bits of the complete Hangul code that gives 2-byte code to syllable unit Hangul font and Hanja font or the lower 15 bits of 2-byte code. The combined Korean code (FIG. 1) sets the upper bit 0xF bit to '1' as shown in Table 2 for the English character code and identification.

TABLE 2

Combination of 16 bit combinatorial Hangul code ('one' character example) Identifier (First) ㅏ (neutral) B (jongjong) F E D C B A 9 8 7 6 5 4 3 2 One 0 One One 0 One 0 0 0 0 0 One One 0 0 One 0 0

As described above, the characteristics of the Hangul code are assigned to the lower 15-bit area of the 2-byte code by assigning a 2-byte individual code to a character or by combining two, mid, and final codes; In Korean search, it was impossible to search keywords by acronyms.

An object of the present invention is to provide a method and an apparatus for retrieving Hangul abbreviations, which simplify the search of Hangul data, by simply inputting the keywords of Hangul data into the Duom string and extracting them from the Hangul data.

2 is a block diagram of a search computer;

3 is a block diagram of an embodiment of the present invention acronym search process;

This invention Hangul acronyms search like this;

In receiving and establishing a keyword from a keyword input device, reading data from the database sequentially in a search unit and comparing the keyword with the keyword,

Receive an input string of Hangul keyword string from the input device, establish it as a keyword, and shift to data search;

Compare the searched Hangul data in the search unit in the data search.

A method and apparatus for retrieving a Hangul consonant string, characterized by converting Hangul data into a consonant string data corresponding to a keyword and comparing the result with a keyword.

The present invention will be described with reference to the flowchart in Fig. 3 as follows.

The main control unit provides a dialog box and a cursor to the user through the input device and the display device to define the Korean code type (combined type, complete type, or others) if the Korean code type of the database is not defined. (This process is omitted if the Hangul code is defined as a combination code.) The dialogue for this user interface includes the dialogue over the network.

The main control unit provides a dialog box and a cursor to the user and receives the Hangul two character string keyword from the input device to establish a byte type two character string. For example, as shown in Table 3, for the string 'Sejong the Great', the consonant string 'ㅅ ㅈㄷㅇ' (k0) of the combined Hangul code is established as a byte type consonant string (k1).

Table 3

Keyword 5-bit double code string (k0) S1011 1110 C101 ㅇ 1101 Byte Type Keyword Abbreviated String (k1) 1011000 1110000 101000 1101000

The byte type keyword abbreviation string is established; Preserve the keywords and move on to data retrieval.

Iterative comparison process of data retrieval includes;

Read a data string from the database according to a specified format (search unit);

If the read data string is not a combined Hangul code, the Hangul code conversion program is called to convert the data string into the Combined Hangul code;

As shown in Table 4, a 5-bit double code string bit mask is extracted from a data-combined Hangul data string, established as byte type double string data, and keyword and data are compared.

If the comparison result is the same, data data is stored as search result information repeatedly;

When the search of the data area is completed, the searched data information is provided to the dialog box.

Table 4

Read Hangul string three Bell versus king 16-bit code string 1010110101000000 1011100110110111 1001010010000000 1011010111010111 Beat Mask Double Code String 01011 01110 00101 01101 Byte type prefix string 00101100 00111000 00010100 00110100

In the present invention, as shown in Table 5, the byte-type abbreviation string of Table 4 may include a Korean identification bit in the upper 0X7 bits.

Table 5

Two-chord string 01011 01110 00101 01101 Byte type Sequential code string 10101100 10111000 10010100 10110100

As described above, the present invention can input a Korean search keyword as a simple acronym string, so that the Korean search can be easily and quickly processed, and it is particularly easy to input a search keyword through a compact keyboard of a communication device such as a portable terminal device. It is possible to facilitate the retrieval of Hangul files in Hangul name file management.
