Abstract

PURPOSE:To reduce troubles for inputting a retrieval word, and to improve the retrieval efficiency by designating and inputting directly the retrieval word by a pointing device, etc., into an optional character string and the structure of the character string displayed on I/O, and executing the retrieval. CONSTITUTION:A character string and the structure of the character string of a sentence, etc. obtained by some means are displayed on an I/O 3. Subsequently, it is confirmed that an inquiry word or a character string has been designated and inputted. Next, a logical operator between them is inputted. It is executed, for instance, by instructing OR or AND by a pointing device, etc. A comparison operating part 2 executes a pattern matching of information expressed by the inputted inquiry word or character string and the logical operator, and information which is stored. In case they have matched each other, the information of the matched information store part is transferred to a retrieval information store part 8. Also, this information is displayed on the I/O 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a search method for stored information, and particularly to an information search method suitable for easily inputting a search query term.

[Background of the invention]

Conventional information retrieval systems (1) assign keywords corresponding to the information from a predetermined set of keywords at the time of information storage;
Alternatively, input the logical sum, logical product, etc. of keywords from a keyword or an input device such as a tablet, or (2)
) The method used was to enter a search query word as an arbitrary character string from an input device such as a keyboard or tablet to perform a character string matching search. (Reference: G, 5alton”
Autos+aticInformation Or

McGrav-Hill) Therefore, any sentence displayed on an input/output device such as a display by some means, or one verse and nine phrases.

When specifying a search query word from a string of words or a structure of a character string, you must read the text, decide on the search query word, and enter it again using an input device such as a keyboard. However, the disadvantage is that there are many operating means for inputting a search query.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to extract text from any text displayed on an input/output device, or from character strings such as clauses, words, etc. The object of the present invention is to provide a method for efficiently specifying and inputting search words for information retrieval.

[Summary of the invention]

In order to achieve the above object, the present invention provides one or more characters in any sentence displayed on an input/output device, or in a character string or character string structure such as five verses, two phrases, words, etc. word or
Character strings, and in the case of multiple characters, the logical sum, logical product, etc. between them can be specified/entered directly using a pointing device, etc., and a character string match search can be performed based on that information. That is.

[Embodiments of the invention]

The present invention will be explained below by way of an example.

First, the present invention will be explained in detail with reference to FIG.

In FIG. 1, reference numeral 1 indicates a central processing unit (C: PU), and reference numeral 2 indicates a comparison calculation unit that performs pattern matching between input query terms and stored information. 3 indicates an input/output device. 4
is a memory, 5 is a part that stores input query words,
Reference numeral 6 indicates a portion for storing input logical operators, 7 a portion for storing accumulated information, and 8 a portion for storing search information obtained by pattern matching in the comparison calculation unit 2.

Next, the operation will be explained based on the control procedure diagram of the present invention in FIG. 2 and with reference to the input/output screen example in FIG. 3 as necessary.

In step 9, the text obtained by some means, or a character string such as a phrase, a word, or the structure of a character string is displayed on the input/output device 3.

In step 10, a query word is specified and input into the displayed character string. In this case, as shown at 17 in the input/output screen example in FIG. 3, one query word or the first and last characters of a character string may be indicated using a pointing device or the like. For example, in No. 17, ``Ken'' is specified as the first character, and ``Ministry of Commerce J'' is specified as the first character.
As in the example above, it is shown by drawing an Angline that the ``quotient'' and the last ``province'' have been specified.
There may be more than one query word or character string.

In step 11, it is confirmed that the query word or character string has been specified and input.

In step 12, logical operators between them are input.

This is done, for example, by indicating whether it is Or (logical sum) or And (logical product) using a pointing device or the like, as shown at 18 in FIG.

In step 13, the comparison operation section 2 performs pattern matching between the input query word or information expressed by a character string and a logical operator and the information stored in FIG. 17. In this case, it is possible to apply search techniques such as forward, middle, and backward matching of the query word or five character strings.

Step 14 indicates that if the patterns match, the process proceeds to step 15 in which the matched information in the information storage section is transferred to the search information storage section 8.

In step 16, the search information stored in 8 is displayed on the input/output device 3.

As explained above with reference to the embodiments, the information retrieval method of the present invention can be implemented by either software or hardware such as a dedicated processing device.

〔Effect of the invention〕

According to the present invention, a search term for information retrieval can be directly entered into any text displayed on the input/output device by some means, or into a character string or character string structure such as a phrase or word. Specified using a pointing device, etc.

This reduces the number of steps required to input search terms for information retrieval, which is effective in improving search efficiency.

Claims (1)

[Claims] In an information utilization system consisting of an information storage mechanism and a search mechanism, when searching for information, the input method for the search term is a displayed sentence, a string of characters such as a clause, a phrase, a word, etc., or a structure of a string of characters. An information retrieval method characterized by specifying one or more words or character strings, and in the case of a plurality of words, a relation such as a logical sum or a logical product thereof using a pointing device.
