Abstract

PURPOSE: A method for correcting a key input error for an information retrieval is provided to detect a key input error without the user's judgment, and by automatically correcting the error. CONSTITUTION: An information retrieval engine receives an input query from a user, and performs an information retrieval(201). It is confirmed whether the number of a retrieval result is "0"(202). In case that the number isn't "0", the retrieval result is outputted(203). In case that the number is "0", it is checked whether the query inputted is mingled with Korean/English(204). The retrieval result is made as "0" and outputted(205). The query is divided as the unit of word(206). It is judged whether the query is formed of Korean(207). It is confirmed whether there's a word element(208). In case that there's no word element, the retrieval result is made as "0" and outputted(209). A conversion into an English corresponding key is performed(210). It is checked whether the query in English can be formed with Korean characters(211). The English characters are converted into Korean characters corresponded(213). A retrieval with the query converted is performed(214). It is confirmed whether the number of retrieval result(215). A result that there's no retrieval result is outputted(216). A retrieval result according to the query converted is outputted(217).

Description

How to fix keystroke errors for information retrieval {METHOD OF CORRECTING TYPING ERROR FOR ON-LINE INFORMATION RETRIEVAL}

The present invention relates to a method for correcting a key input error for information retrieval and a computer-readable recording medium recording a program for realizing the method. In particular, the present invention relates to a case where a Korean user or a Korean information retrieval user performs an information retrieval. Key input error correction method for information retrieval that corrects input errors such as the case of English input in the key state and Korean input in the English key state so that the query can be input as it is regardless of the key selection. A computer readable recording medium having recorded thereon a program for realizing the method.

The information retrieval engine is an automatic document collection process that automatically collects the target documents scattered in various spaces, a morphological analysis process that extracts words that form sentences by analyzing sentences in the document, and an automatic index that automatically selects keywords in the document. A large number of processes, including an infrastructure storage process for storing indexed results in an efficient infrastructure for high-speed use, a search process for finding the desired document in the stored infrastructure, and a user interface process that connects users and searchers. Process and retrieve documents. As the use of information retrieval has become popular, various types of queries come in, ranging from refined queries inputted by experts to queries with many mistakes and unrefined queries. A large part of these mistakes is a query entered with the wrong choice of Han-Young key.

When a query is entered with incorrect Korean-English key selection, the search engine outputs no search results, and the user examines what is wrong and finds that the query is entered differently than intended. There was a problem entering and receiving the search results. At this time, if the system automatically recognizes and corrects the user's mistake, the user will feel more comfortable than other search engines. In addition, a user who knows the operating characteristics of such a system may search by pressing a letter key without having to press the Han Young key, and a Korean font is installed on a personal computer (PC) among foreigners who know Korean or Korean. It is possible to view Korean documents through a web browser, but even if it is not possible to input Korean because it is not a Korean operating system, if you know only the layout of the Korean keyboard, there will be a convenient way to search for the desired data by typing Korean in English.

The basic premise of the key-in error correction method is that the Han-Young key error judgment should be made only when there is confirmation. The Korean-English automatic conversion function, which is widely applied to word processors, emphasizes the convenience of automatically changing the Korean-English key according to the input pattern even if the Korean-English key is not selected, rather than the Korean-English key selection error. Judgment is involved.

However, the information retrieval engine is characterized in that the selection error of the Korean-English key is strong, and that the judgment of the user cannot be involved. This is because there is no improvement in the convenience of inputting and re-writing the query when the final judgment process regarding the error by the user's intervention is necessary.

In other words, in the case of using an information retrieval engine in the past, it is inconvenient to use the user because there is no function of determining the Han-Young key error without any judgment of the user and automatically correcting the error to replace the normal query. There was this.

The present invention has been made in order to solve the problems described above, and performs a key input error determination without determination of the user and automatically corrects the error to replace the normal query for outputting the search results for information retrieval It is an object of the present invention to provide a method for correcting a key input error and a computer-readable recording medium having recorded thereon a program for realizing the method.

The method of the present invention for achieving the above object, in the key input error correction method for information retrieval applied to the information retrieval system, there is no information search results in the information retrieval system in the information retrieval system A first step of dividing the query into word units and determining whether the query is a query input in Korean; A second step of outputting a search result according to the converted query by converting a Korean query having a lowercase letter to an English corresponding key if the query result in the first step is determined in the first step; And a third step of outputting a search result according to the converted query by converting to a keyboard corresponding Korean for a query that can be completed with Korean characters, if it is not a query in Korean. Characterized in that it comprises a.

In addition, another method of the present invention is a key input error correction method for information retrieval applied to an information retrieval system, wherein the first language / second language mixed query has no data retrieved as a result of the information retrieval in the information retrieval system. A first step of dividing the query into word units for a non-query, and determining whether the query is an input query in a first language; As a result of the determination of the first step, if the query is a first language, the search result according to the converted query is converted by converting the first language query statement that can be completed in the second language into a corresponding second language. Outputting a second step; And as a result of the determination in the first step, if the query is not a first language, the second language query may be converted into a corresponding first language and then converted into a corresponding first language. And a third step of outputting the result.

The present invention also provides an information retrieval system having a large-capacity processor, wherein the query is divided into word units for a non-Hangul / English mixed query without the data retrieved as a result of the information retrieval from the information retrieval system. A first function of determining whether the input query is a query; A second function of outputting a search result according to the converted query by converting a Korean query having a lowercase letter to an English corresponding key if the first query is a result of the determination of the first function; And a third function of outputting a search result according to the converted query by converting to a keyboard corresponding Korean for a query that can be completed with Korean characters if it is not a query in Korean as a result of the determination of the first function. A computer readable recording medium having recorded thereon a program for realizing the present invention is provided.

In general, unlike users of English-speaking languages, Korean users need to change Hanyoung key according to a word when using the information search machine. There is a significant error in entering the Korean English key. The present invention intends to provide a method for automatically correcting such an error, and when applied to it, it is possible to insert a query as it is without selecting a Korean-English key.

That is, according to the present invention, if the search results are not mixed and the Hangul characters are not mixed, the search is started only on the query statements that may cause the Han-Young key selection error. A), 'b', 'ㅏ', 'ㅑ'), and in case of English input, check whether the Hangul can be completed when replacing with the corresponding Hangul on the keyboard. As a target, after converting the Korean-English key into the corresponding query, the searcher is called again with this query, and if there is a search result, it is determined that the Korean-English key is input error.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of an information search engine to which the present invention is applied.

The information retrieval engine includes a document collector (1), a document filter (2), an automatic indexer (3), an infrastructure storage device (4), a language information interface (5), a user interface (6), an information retriever (7), and a document. The base interface 8 includes a document base 9, a language information storage unit 10, and a collected document storage unit 11.

As shown in the drawing, an information search engine to which the present invention is applied includes a document collector 1 for collecting a target document to be searched, a document filter 2 for extracting a certain type of information from the collected document, A document processing step performed by an automatic indexer (3) for automatically indexing the binary information, and an infrastructure storage (4) for storing the indexed results in an infrastructure, and in a format that a search engine can understand by receiving a user's query. A user interface (6) that converts the query into a format that can be easily viewed by the user, an information searcher (7) that receives the user's query, and finds related documents in the order of the most relevant, The document information required by the searcher 7 can be divided into information utilization steps made in the document database interface 8 or the like which extracts from the infrastructure.

In the basic structure of the information retrieval engine as described above, the present invention looks at the search result and the type of the input query statement inputted through the user interface 6, and selects a Hanyoung key input error candidate to replace the error corrected query statement. The searcher 7 is called again to determine if there is a search result, which is an English-English key error, and outputs the search result of the changed query to the user.

2 is a flowchart illustrating a method for correcting a Korean-English key input error for information retrieval according to the present invention.

2 is a flowchart illustrating a process of recognizing and automatically correcting a Korean-English key selection error and outputting a search result intended by a user.

First of all, if the query is searched for only 0 of the input query, if the query is mixed with Korean / English, the chances of Korean-English selection error are low and discarded. If not, the query is divided into word units, and then the Hangul / English character distribution of the input query is used. In the case of a word composed of Hangul, the incomplete Hangul among the constituent characters, that is, 'ㄱ', 'ㄴ', ' Check if there is a phoneme character such as ㅏ ',' ㅘ 'and convert it to the corresponding English word only if there is a lowercase letter, and if the word is composed of English, make sure that it is completed in Korean when converting the constituent character to the corresponding Hangul. Only when it is completed is converted to the corresponding Hangul. The searcher is called with the converted query, and if there is a search result, it is determined to be a Han-Young key selection error and the converted query and the search result are output to the user.

This will be described according to the flow shown in the drawings.

The information search engine receives an input question from the user and performs an information search (201). It is checked whether the number of search results is zero (202). As a result of the check, if the search result number is not 0, the search result is output (203). If the search result number is 0, it is checked whether the input query is a mixed query of Korean and English (204). As a result of the check, if the query was a mixed Korean / English, there is a small probability that it is a Hanyoung key input error, and the search result is output as 0 (205).

As a result of checking whether the input query is a mixed query of Korean / English, if the mixed query is not a mixed query of Korean / English, the query is divided into word units (206), and whether the input query is in Korean. Determine (207).

As a result of determining whether the input query is in Korean, if it is in Korean, it is checked whether a lowercase letter such as 'ㄱ' or 'ㅏ' exists (208).

As a result of checking whether the lowercase letter is present, if the lowercase letter does not exist, the search result is output as 0 (209).

As a result of checking whether the lowercase letter is present, if the lowercase letter exists, it is divided into Korean characters and converted to an English corresponding key (210).

As a result of determining whether the input query is in Korean, if it is not in Korean, it is checked whether the input query can be completed with Korean characters (211).

As a result of checking whether it is possible to complete Korean characters, the search result is output as 0 if it is not possible to complete Korean characters (212).

As a result of checking whether it is possible to complete with Korean characters, if it is possible to complete with Korean characters, the alphabet is converted to Korean corresponding to the keyboard (213).

A search is performed with the converted input query (214), and the number of search results is checked (215). As a result of the check, if there is no search result, the search result is not output (216).

As a result of checking the number of search results, if there is a search result, a search result according to the converted query is output (217).

In the above embodiment, the processing for the input error of the Han-Young key is performed. However, the present invention uses not only the Korean-English key but also the Korean-Japanese key, the Korean-Chinese key, the Han-bulk key, the English-Japanese key, and the like. By using a language or the like, all of them may be used even when a language selection error may occur in key input.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

According to the present invention as described above, if a wrong query is mistakenly transmitted to the search engine without confirming the selection of the Korean-English key, the search result can be obtained immediately without the trouble of checking the error and inputting the search word again.

In addition, the present invention, the user who feels uncomfortable with the selection of the Korean-English key to press only the keyboard without selection has the effect of increasing the convenience of the user.

In addition, the present invention, the Hangul font is supported through a web browser, but if the Hangul input is not the Hangul Windows, it is effective to search by typing in English based on the Korean keyboard without installing additional software.
