Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information retrieval device that stores words and phrases that overlap in language when a plurality of language memories are selected using a common address, and displays the overlap when reading out the words and phrases.

Generally, when searching for information, it is not possible to search from the information to be searched. For example, it is not possible to look up English from Japanese using an English-Japanese dictionary, so a Japanese-English dictionary is also required.

The present invention can search from any language, and can easily search for words or phrases that have multiple meanings, and can display duplicates according to the search status when reading duplicate words. The present invention provides an information retrieval device configured with electronic circuits.

FIG. 1 is a block diagram of an information retrieval device showing one embodiment of the present invention. In the figure, reference numeral 1 denotes a keyboard, which has alphabet keys from A to Z, a language selection key for selecting English, French, German, and Spanish, a search key for alphabet or group, and a clear key. There is. The keyboard 1 has the keys wired in a matrix, receives a key scan signal from an input/output gate circuit 11, and outputs a key signal to the input/output gate circuit 11 when a key is pressed.

The key signal is given to the control circuit 2 via the input/output gate 11, and the control circuit 2 reads out and executes the program in the program memory 3 according to the key, and when a character key is pressed, the first register 4
1, a character signal is input and stored. Further, when the language selection key is pressed, the state is stored in the language selection memory 51, and when the search key is pressed, the state is stored in the search memory 52. The language selection memory 51 has four outputs and is connected to language memories 61-64. Also, the search memory 52 is a duplicate memory 53 and a gate G.
Connected to 1.

The language memories 61 to 64 are memories corresponding to English, French, German, and Spanish, and if each is configured with a 144K bit CMOS-ROM, for example, each character can store 24,576 characters with 6 bits. Therefore, if one word is composed of about 10 characters, it is possible to memorize about 2,400 words. Each memory 6
Addresses 1 to 64 are selected by a common address line 65 and output to a data line 66.
Address lines 65 are supplied with address signals A0 to A14 from an address register 67.

The output of the address register 67 is sent to the adder 68.
The adder 68 changes and advances the address. Language memory 61~
64 is a language selection memory 51 at the same time that a common address is selected by the address register 67.
Since one of the languages can be selected by , the contents of the corresponding language are read out to the decoder 43 in synchronization with the signal from the readout signal line 69. The read contents include character information, symbols or numerical values, and address information. In the case of character information, it is led to the second register 42 via the decoder 43, and in the case of symbols or numerical values, it is led to the redundant memory 53. Output. If the read content is address information, it is also applied to the adder 68 via gates G1 and G2 in addition to the decoder 43, and the content of the address register 67 is changed through the adder 68.

The control circuit 2 normally includes a key scan program that detects presses on the keyboard 1, and a display circuit 8 via an output gate circuit 71 and a column drive circuit 72.
is running the display program that drives it. When a key is pressed, a program corresponding to the key is executed, information is searched, and the results are displayed.

The display circuit 8 has, for example, display digits for 10 characters, and each digit is composed of 5 columns and 7 rows, and an element 81 for displaying a special symbol below only a specific digit;
It has 82 and 83.

The language selection memory 51 is composed of a 2-bit register, which stores which of the four languages has been selected by the language specification key in four states from 00 to 11. If cleared in advance, it will be set to 00.
For example, the English memory 61 is mainly selected.

The first and second registers 41 and 42 are 10-digit registers with 6 bits per digit.The first register 41 mainly stores codes corresponding to characters input from the keyboard 1, and the second register 42 stores Codes corresponding to characters read from the language memories 61 to 64 are stored. 1st and 2nd register 4
The contents of 1 and 42 are compared by a subtractor 44. At the time of comparison, the contents of the second register 12 are subtracted from the first register 41 by the subtracter 44 for determination.

In this example, alphabets A to Z are 000001.
It corresponds to 6 binary bits of ~011010, and A<
Since the relationship is B<...<Z, search in alphabetical order is possible by subtraction. For example, English
When inputting ABLE to find out other supported languages, if the English memory 61 is searched sequentially in the order of A, ABLE, ABOUT,..., then A<ABLE, and vice versa.
Since ABLE<ABOUT, it is possible to perform a search by determining the size of the word's character code.

Note that if words are stored in alphabetical order in each of the language memories 61 to 64, correspondence cannot be established between the language memories. For this reason, in each language, an address code in alphabetical order is stored at the same time as the character code of the word, and the next word is retrieved by reading out the address code. For example, after the character code of the word ABLE, an address code indicating the location where the character code of the next word ABOUT is stored is also stored, so it is possible to search for words in alphabetical order. Furthermore, words with the same meaning are stored in the same address location between language memories, so if the address of the English BAG is 1234, the French SAC, the German
Same as TASCHE and BOLSA in Spanish
1234 number is memorized. Therefore, the language selection memory 51 can instantly switch and read out the contents of any other language memory from any language selection memory. In other words, if each language is configured with a single memory LSI, the character code of the corresponding word can be read out simply by changing the chip select of each LSI.

In each of the language memories 61 to 64, one word may have multiple meanings, and if addresses are simply made to correspond one-to-one, it may not be possible to distinguish between them when reading. For example, English TROUSERS, PANTS,
SLACKS is PANTALON in French.
, and if you simply compare English and French, the same word will be read three times in French. For this reason, words with duplicate meanings, such as the French word PANTALON, are distinguished by adding a symbol indicating duplication or information indicating the number of duplications. For example, since the characters A to Z are 000001 to 011010, the decoder 43 distinguishes 0 to 9 as 100000 to 101001 if they are numerical values, and 111111 if they are symbols. Therefore, each word consists of 10 characters of character information, 3 characters of address information, and 14 characters of numerical or symbolic information.

Next, the operation shown in FIG. 1 will be explained using the flowchart shown in FIG.

First, normally, the contents of the first register 41 are the contents of the subtracter 4.
4 to the control circuit 2 and displayed on the display circuit 8. Next, a key scan is performed,
Pressure on the keyboard 1 is detected from the control circuit 2 via the input/output gate circuit 11 . If no key is pressed, the above operation is repeated.

If there is a key press, for example, character keys A to Z
When is pressed, the search memory 52 is set, the gate G1 operates to transmit the address signal from the gate G2 to the adder 68, and at the same time the character code is stored in the first register 41 via the data line 45. Ru. Subsequently, if the language selection memory 51 selects English, the contents of the English memory 61 are read into the second register 42, and the contents of the first and second registers 41 and 42 are compared in the subtracter 44. Ru. As a result of the comparison, if the contents of the second register 42 are smaller than the contents of the first register 41, then the address register 67 is changed to a new address and compared with the next word. Furthermore, the read contents of the second register 42 are transferred to the first register 41.
If the contents match, the original display and key scanning operation will be restored. If the contents of the second register 42 become large, there is no match, and an error occurs.

When the alphabet search key is pressed, the search memory 52 is set, the gate G1 operates to transmit the address signal from the gate G2, and the contents of the address register 67 are changed every time a search is performed to search for the next word in alphabetical order. is read out and displayed in the first register 41. At the same time, the duplicate memory 53 is activated by the output of the search memory 52, and stores the symbols or numerical values of words that are duplicated at the time of reading.
2,83 is displayed.

Therefore, for example, when the French language memory 62 is selected and the alpha search key is pressed after inputting the letter key "P", words starting with P are searched in order and displayed on the display circuit 8. but,
As mentioned above, it has overlapping meanings.
When PANTALON is read out and displayed, the symbols 81, 82, and 83 of the display circuit 8 are lit and displayed in sequence based on the information stored together with the character information indicating that it has a duplicate meaning. Indicates that words have overlapping meanings.

When the group search key is pressed, the search memory 52 is reset, the gate G1 operates to transmit the output of the address register 67, and the "1" signal from the control circuit 2 is sent to the adder 68 for each search.
, the address register 67 is sequentially updated, and the new word is read out and displayed. Then, the duplication memory 53 becomes inactive and does not store even if a symbol or numerical value indicating duplication is output from the decoder 43. Therefore, even if words are duplicated, they are not displayed with a code. In other words, unlike alphabetical order, group search simply uses linguistic memory 61 to 6.
Since the words are read out in the order in which they are arranged in 4, by classifying them into specific groups in advance and arranging them according to the classification, even words that overlap are not read out consecutively, and a code indicating duplication is not required.

Symbols or numbers are memorized for each of the duplicated words above, but if the words are duplicated three times, the first
By adding "3" to the word, "2" to the second word, and "1" to the third word, the total number of repetitions or their order can be known. or third
The th word may be set as "0" and there may be no repeated words. Alternatively, special symbols can be displayed by adding common symbols to duplicate words.

When a desired word is set using the character key or search key, the language selection key is pressed to select another language memory in order to view other languages corresponding to the desired word. By reading out and displaying the contents of the common address in the first register 41, it is possible to know the words of the desired language.

As described above, the present invention stores information for distinguishing whether or not each word has a duplicate meaning along with character information of the word in the linguistic memory, and when searching, reading out, and displaying duplicate meanings. In the case of words that have meanings, the display circuit is configured to display and indicate instruction symbols, so it is easy to see if the words have duplicate meanings, which is very convenient when choosing which translation is more appropriate. It is.
