Description

The invention relates to computing and can be used to search for a letter by letter program of information that does not require coding and is requested in natural language. A device is known comprising a keypad, a search image forming unit, a memory unit, a program control unit, a coding node, a comparison circuit, a memory device on a magnetic tape, a print result search unit i. This device is intended for search of bibliographic references and is complex because it uses various types of storage media. The closest in technical essence to the present invention is a device comprising sequentially connected a keypad, an input unit, a word and sentence forming unit and an output unit, wherein the word and sentence forming unit includes memory elements and elements. The dataset of statistical data, for example, expressed in vice tables, the device contains a large number of elements. Each word should be fixed with a memory element using AND elements. The aim of the invention is to reduce the hardware of the device. The goal is achieved by the fact that, in a block forming words and sentences, the inputs of the memory elements of the table names, the row names and the column names through the corresponding elements I are connected to the inputs of the block, the outputs of the memory elements of the table names through the first element I are connected to the input of the first memory element , the output of which is connected to the first output / port of the block and device and to the first inputs of the second and third elements AND, the second outputs of which are connected respectively 1; 1 to 11 about the outputs of the memory elements of the rows, output And the second element of the memory is connected to the second outputs of the block and the device and the first inputs of the fourth and fifth elements And, the output of the third element And through the third memory element is connected to the third outputs of the block and the device and the first inputs of the sixth And the seventh elements And, the second inputs of the fourth, fifth, sixth and seventh elements And soy is 10

with the outputs of the corresponding memory elements of the column names, and the outputs are connected to the outputs of the block.

FIG. 1 shows a diagram of the device; see 2 - an example of the implementation of a block of 15

yes, where the keyboard panel 1, input block 2, block 3 forming words and sentences, block 4 outputs, elements 5-10, the memory elements of the names of tables 11 and 12, the memory elements of the names of lines 13 and 14, the memory elements are shown column names 15 and 16, elements And 17, memory element 18, element And 19, memory element 2O, element And 21, memory element 22, elements And 23-26, the outputs of the device are 25 va 27, 28 and 29, elements AND 30-37, elements NOT 38 AND 39, elements OR 40 and 4, memory elements 42-48, delay line 49. FIG. Figure 1 shows the organization of the word and sentence formation unit 3 for searching data from a table whose name consists of two words (elements 5 and 6, memory elements 11 and 12), two strings {elements 7 and 8, memory elements 13 and 14), two columns (elements 9 and 10, memory elements 15 and 16). Element And 17 and memory element 18 select the name of the table. Elements L 19 and 21 and memory elements 2О and 22 select the name of the table and the row, and elements 23, 24, 25 and 26 select each field of the given table. The input (data) block 1 together with the keypad allows you to receive at the corresponding outputs the signals of all the characters of the typed word that excite the corresponding element I. It contains (see Fig. 2) a storage matrix. Each matrix column corresponding to the sequence number of a character in a word consists of a memory element for each character of the used alphabet, the input of each of which is connected to the output of the corresponding element AND, one input of the element ri is connected to the keypad, the second is from the output

the At the output of the OR 40 element, a positive potential appears, which places the record of the next character in the next column. Potential from the output

the input of the AND elements of the column in which the recording occurred, thereby prohibiting the repeated recording of the symbol in the same one. column. Spell out the required word

Claims (2)

is inserted into the device. At the same time, the corresponding element AND 5 (Fig. 1) of block 3 will transfer the memory element 11 to the state corresponding to the memorization of this element OR of the previous column, and the third through the NOT element with the output of the OR element of this column, the inputs of the OR element are connected to the outputs of the elements memory of this column. The number of columns is equal to the number of characters in the word. When one of the keys is pressed, the corresponding memory element 45 (Fig. 2) in the first column goes to another element OR 40 is inverted and sub-array. Before starting the next word input, the input unit is reset to the initial state by applying a reset signal to the memory elements 42-48 (see Fig. 2). When typing all the words of the table name, the memory element 18 will memorize it and will be excited output 27. The keypad 1 of the row name will bring the corresponding memory element of the row name 13 to another state, the output 28 will be excited. The set of the column name will cause the corresponding memory element to be excited ti 15, element 23, the output of which is connected to the output unit. Claims An information retrieval device comprising a serially connected keypad, an input unit, a word and sentence generation unit, and an output unit, the word and sentence generation unit including memory elements and AND elements, characterized in that, in order to reduce the equipment, the block forming words and sentences, the inputs of the memory of the names of the table, the names of the rows and the names of the columns through the corresponding elements of And are connected to the inputs of the block, the output of the NiCHTOB memory of the names of the table through p The first AND element is connected to the input of the first memory element, the output of which is connected to the first outputs of the block and device and to the first inputs of the second and third elements AND, the second inputs of which are connected respectively to the outputs of the memory elements of the row names, the output of the second element AND through the second memory element is connected to the second outputs of the block and the device and to the first inputs of the fourth and fifth elements I, the output of the third element I through the third memory element connected to the third outputs of the block and the device and to the first 7 22A in sixth and seventh rows element and the second inputs of the fourth, fifth, sixth and seventh elements M are connected to respective outputs of memory elements of column names, and the outputs are connected to the outputs of the block.
