DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information retrieval apparatus,
The present invention relates to an information search device that searches for heading information stored in a storage unit in advance and outputs the searched heading information and corresponding information to a predetermined output unit.

[0002]

2. Description of the Related Art Conventionally, in an information retrieval apparatus such as an electronic dictionary, heading information (keywords and headwords) and corresponding information (notation and meaning) are stored in a storage device, and the heading information is stored in a predetermined method. 2. Description of the Related Art There is known an apparatus that searches for information and outputs the searched heading information and corresponding information corresponding thereto using a display device or the like.

[0003]

However, in the conventional system, for example, as shown in FIG. 4, despite the fact that the notation with the headword has overlapping information, it is stored in the storage device as it is. Therefore, there is a problem that the more the number of words increases, the larger the occupation capacity of the useless storage area.

An object of the present invention is to solve the above-mentioned problems and to provide an information retrieval apparatus capable of storing a large amount of information with the same storage capacity while minimizing useless information.

[0005]

In order to achieve the above object, the present invention stores a plurality of combinations of heading information and corresponding information corresponding to the heading information, and stores the heading in one combination. Kana information is stored as information, and as the corresponding information corresponding to the heading information,
Storage means for storing kanji information and identification information corresponding to a portion other than the kanji information in the heading information,
Searching means for searching for the heading information corresponding to the input information from the heading information in the storage means; and referring to the corresponding information corresponding to the heading information obtained by the searching means, the identification information is included in the corresponding information. And a complementing means for complementing the contents of the corresponding kana part of the heading information in place of the identification information in the correspondence information and outputting the complemented correspondence information.

[0006]

According to the present invention, the corresponding information is complemented and output by referring to the heading information. According to this, since the size of the correspondence information stored in advance can be reduced, more correspondence information can be stored in a storage medium having the same size.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments shown in the drawings.

FIG. 1 shows a block diagram of an information retrieval apparatus employing the present invention. In the figure, reference numeral 2 denotes a CPU composed of a microprocessor or the like, which executes each process of the program 4a stored in the ROM 4 according to an input from the keyboard 1.

Here, the keyboard 1 is connected to the CPU 2 via interface means. The ROM 4 stores a dictionary 4b in which heading information and corresponding information are stored, and information of the dictionary 4b is searched using a character string input from the keyboard 1. The RAM 3 has an input buffer 3 for temporarily storing input data from the keyboard.
a, a display buffer 3b for expanding data to be displayed, and the like.

The display 6 is an LCD panel or C
It is composed of an RT display or the like, and is driven by a display driver 5 under the control of the CPU 2.

FIG. 2 is an external view of the apparatus according to the present embodiment. Reference numerals 1 and 6 respectively denote a keyboard 1 and a display 6 in FIG. The keyboard 1 includes a character input key 1a for inputting an alphabet or the like, a search key 1b for executing information search, a cursor key 1c, and the like.

FIG. 3 shows a state in which a character string is input using a keyboard, and information retrieved using the character string is displayed on a display. 3- (a) shows the middle of the character string input,
(B) shows a state in which the input has been completed, 3- (c) shows a state in which the search key has been pressed and the word "spoken" has been searched, and 3- (d) shows a state in which the search key has been pressed again and the next Is displayed in a state in which the word "Farewell" is displayed.

FIGS. 5 and 6 show the contents of the dictionary 4b, in which data is stored in headings and notations, respectively. "/" Indicates an share information in headings, as shown in FIG. 3, Han notation when displaying information
Required to read the characters . FIG. 5 shows an example in which all the headings are stored in hiragana. In this way, when comparing the input word with the headword, it is not necessary to convert the hiragana for the headword. It's easy. FIG. 6 shows an example of the present invention, in which a code for referring to a heading is stored.
'c1' indicates a hiragana reference, and 'c2' is a code indicating a katakana reference (c1 = 01H, c2 = 02H).

FIG. 7 is a flowchart of data processing.
First, key input processing is performed in step S1, and step S2
To determine the key, and proceed to any of steps S3, S4, and S5 according to the result of the determination, and then proceed to step S6. In step S3, when an input word is input from the character input key 1a, a process of setting the input word in the input buffer 3a is performed. In step S4, when the search key 1b of the keyboard 1 is input, an input in the input buffer 3a is performed. A dictionary search process as shown in FIG. 6 is performed for the word. In step S5, processes other than S3 and S4 are performed. In step S6, a process of displaying the data set in the display buffer 3b on the display device 6 is performed. An information search process is performed by repeating the above series of processes.

FIG. 8 shows the search processing in step S4 in detail. The comparison is repeated between steps S101 to S104 until the input word is equal to or larger than the headword (a headword is found). . That is, S1
01 compares the input word with the headword, and determines in S102 whether the input word is smaller than the headword.
To advance the headword by one. In S104, it is determined whether the headword is completed. When the headword is completed, an error message is set in the display buffer in S116, and the process returns. If it is not the end, S
Return to 101. Input word and the entry word in step S102
If the entry is equal to or greater than that and a headword is found, the process proceeds to step S105, and in a series of subsequent processing, the found headword and its description are set in the display buffer.

First, a pointer is set in step S105 (that is, the start address, P
The head address of the heading is set in TR2), and it is checked in step S106 whether the characters described in the drawing refer to the heading (in this case, the code of the notation is 01H, 02H, or any other code). When the heading is not referred to, since the character of the notation is a Chinese character, it is set in the notation display buffer in step S107 as it is. Next, step S
At 108, the heading (reading of the kanji) corresponding to the kanji (that is, up to the break) is set in the heading display buffer. At this time, the PTR 2 is advanced by a necessary amount. Next, in step S109, the written pointer is advanced by the kanji code length. If it is determined in step S106 that the notation refers to a heading, the process proceeds to step S110, and the reference is hiragana reference (01H) or katakana reference (02).
H) is checked. In the case of katakana reference, the headline is converted to katakana in a series of processes in steps S111 to S113. That is, the value of PTR2 is inserted into the katakana conversion pointer SPTR2 in S111, and the SPT
Convert the heading to katakana with reference to R2 until the break, S
At 113, the value of SPTR2 is entered into PTR2. Next, the process proceeds to step S114, and the heading is set in the notation display buffer until the sharing or the end is reached. Step S
At 115, the pointer described is advanced by the reference code length, and S
The process proceeds to step S117, where it is determined whether the display is completed. If the display is completed, the process returns. Otherwise, the process returns to step S106. By repeating the above series of processing until the notation is completed, the display contents as shown in FIG. 3 (however, not hiragana but not katakana in the figure) are set in the display buffer. S110
If it is determined that the character is a hiragana reference, the process proceeds to S114.

[Other Embodiments] (1) When the head of a heading is the same as the notation word two or more characters earlier, the data capacity can be reduced by coding and holding the heading part. The present invention can be applied to such a case. An example is shown in FIG. 9, but “i / i / da / shin / ぺ” is the same as the previous heading “i / isoreru” in the first three characters, and is thus coded with the code F3H. .

(2) In FIG. 10 and FIG. 11, the correspondence between the kanji and the kana is determined by referring to the kanji reading table without storing the division in advance in the heading, and the code length to be referred to is "c1". "To" cF "(c1 = 01H, c2 = 0)
2H, c3 = 03H,..., CF = 0FH).

Explaining the complement to the notation, the notation "Oi c1 standing c2" corresponding to the heading "Oitateru" firstly reads "Tsui" or "Tsui" from the kanji and its reading correspondence table of FIG. Since it is known that the character is "O", this is compared with the heading, and it is understood that the heading "O" is read. Next, “c1” indicates that it corresponds to one character of Hiragana, and indicates that the heading “I” is to be referenced. Similarly, the reading “ta” is determined for the kanji “Ritsu”, and it can be seen that the heading “Teru” corresponds to “c2”.

As described above, it is possible to refer to a heading from a notation by using a kanji reading table without having to store the division.

[0021]

As described above, according to the present invention, the storage means stores a plurality of combinations of heading information and corresponding information corresponding to the heading information, and further stores the heading information in one of the combinations. By storing kanji information as the corresponding information corresponding to the heading information, and storing kanji information and identification information corresponding to a portion of the heading information other than the kanji information, it corresponds to reading of hiragana. When searching for notation only in katakana, notation only in kanji, or notation in which kanji and kana are mixed, the corresponding information complemented by supplementing the contents of the corresponding kana part of the heading information instead of the identification information in the corresponding information Can be output, the capacity of the correspondence information can be reduced, and the same output as in the case where data is duplicated can be obtained. That is, if the storage means has the same capacity, more words can be stored, so that a product containing more words can be provided at low cost.
