Description

Method and System for Providing Search Service Using Synonym}

The present invention relates to Internet search, and more particularly, to a method of providing a search service using synonyms.

Due to the development and spread of the Internet, various services using the Internet are provided, and a representative example thereof is a search service. When the search service inputs a word or a combination of words to be searched by a user as a query, the search engine corresponds to a search result document corresponding to the input query (for example, a web site, an article, or a search query including a search query input from the user). An image having a file name including the corresponding search query).

In using such a search service, since it is not easy to select an appropriate query word corresponding to a desired search result, users often input a query word other than the query word corresponding to the search result that they want to obtain. Occurs. In this case, since the search system performs a search based only on the actually entered query, users have a problem in that they do not obtain the desired search result.

For example, if a user enters a query called "Super Junior" to get a search result for a group of singers "Super Junior," the search system actually enters an abbreviation of the originally intended query, such as "Shuju." Since the search is performed based on the input query word "Shuju" and the result is provided to the user, the user cannot obtain the search result that he / she wanted.

Meanwhile, the user inputs the query "Dungeon & Fighter" to get a search result for the game "Dungeon & Fighter", but the short form of the query ". It is also possible that more search results for "dunpa" exist to fail to obtain the search results that a user needs.

Therefore, in this case, the user has to re-enter the search query in order to obtain a desired search result, which causes inconvenience to the user using the search service, which may lead to a decrease in satisfaction and reliability of the search service. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a method and system for providing a search service using a synonym capable of determining query terms in synonyms as synonyms.

Another object of the present invention is to provide a method and system for providing a search service using a synonym capable of providing a search service by reflecting whether a search query input by a user is a short or synonym synonym.

In addition, another object of the present invention is to provide a method and system for providing a search service using synonyms capable of constructing a database of abbreviated lists commonly used by users.

Search service providing method using the synonym according to an aspect of the present invention for achieving the above object comprises the steps of determining whether each syllable of the first query is included in the second query in order; When each syllable of the first query is included in the second query in order, determining whether the first query is a substring of the second query; And if the first query is not a substring of the second query, determining the second query as a synonym of the first query.

In an embodiment, the first and second query terms are consecutively input query terms.

Meanwhile, before the step of determining whether each syllable of the first query word is included in the second query in order, a query word having a lower number of syllables is further selected as the first query from among consecutive query words. And determining a number of query terms as the second query.

In another embodiment, the first and the second query is characterized in that the query is removed from the ASCII code.

Here, in the determining whether each syllable of the first query is included in the second query in order, each syllable of the first query is included in the first syllable of each word of the second query. It is characterized by determining whether there is.

In the determining of whether the substring is a substring, the morphemes of the first and second query terms may be analyzed to determine whether each morpheme of the first query is a substring of the second query. .

The synonym determination may include determining whether first syllables of the first and second query words coincide with each other, and when the first syllables of the first and second query words coincide with each other, converting the second query to the first syllable. It is characterized by determining as a synonym of 1 question.

In the determining of whether the first syllable coincides with each other, if the first syllable of the first and second query words does not coincide with each other, determining whether the second query word starts with a specific word pattern. When the second query starts with the specific word pattern, the second query is determined as a synonym of the first query.

In addition, after the synonym determination step, if there is a plurality of the second query determined as a synonym of the first query, characterized in that it further comprises the step of determining a basic query from the plurality of second query.

 After the synonym determination step, when there are a plurality of second queries determined as synonyms of the first query, at least one of a derivative of a basic query, a variant of the basic query, and a derivative of the variant among the plurality of second queries It further comprises the step of removing one.

In example embodiments, when the first and second query terms are consecutively entered query terms, the basic query term is a query word having the highest number of consecutive query count inputs among the plurality of second queries. It features.

In this case, after the synonym determination step, the method further includes matching the first and second query words with synonyms and storing the synonyms in a synonym database.

Meanwhile, a method of providing a search service using the synonym may include receiving a search query word from a user; Determining whether a synonym of the received search query word exists; And providing a search result for the synonym in the search result for the received search query if the synonym of the received search query word exists.

System for providing a search service using synonyms according to another aspect of the present invention for achieving the above object comprises a syllable-containing relationship determination unit for determining whether each syllable of the first query is included in the second query in order; And when each syllable of the first query is sequentially included in the second query, determining whether the first query is a substring of the second query, and wherein the first query is a part of the second query. If it is not a string, the sub-string determination unit determines the second query as a synonym of the first query.

As described above, according to the present invention, it is possible to more precisely and easily determine a synonym as a synonym among query terms input by users.

In addition, according to the present invention, when a search query is input from the user, the search result for the input search query is included in the search result for the input search query or the abbreviation of the input query or synonym, thereby increasing the user's convenience. As a result, the satisfaction and reliability of the search service can be improved.

In addition, according to the present invention, it is possible to continuously build a database of the abbreviation list that is used by the user has an effect that can quickly provide the user with the search results for the abbreviation that is used most recently.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a synonym determination unit according to an embodiment of the present invention. The synonym determination unit illustrated in FIG. 1 determines a synonym of each query language for each query and constructs a synonym database. The synonym determination unit is directly included in a search service providing system using a synonym to be described later, or a search service using a synonym. It can be configured independent of the system.

As shown, the synonym determination unit 100 includes a syllable-based inclusion relation determination unit 120, a substring determination unit 140, and a query filtering unit 160.

The syllable included relationship determining unit 120 determines whether each syllable of the first query is included in the second query in order. In an exemplary embodiment, the syllable-containing relationship determining unit 120 may determine a query word having a lower number of syllables as a first query and a query word having a larger number of syllables as a second query among consecutively input query words. That is, before determining whether each syllable of the first query is included in the second query in order, the first query determines a query having a smaller number of syllables from among consecutively input queries. For example, if a user inputs a query called "Super Junior" and subsequently inputs a query called "Shuju," the syllable-containing relation determination unit determines that "Shuju" with fewer syllables as the first query. , "Super Junior" can be determined as the second query. Therefore, the first query may be determined by checking the number of syllables of the query, as well as the case where the number of syllables is input first as well as the number of syllables first. As a result, the first and second query words are consecutively input query words, and the first query is a query word having fewer syllables than the second query word.

In addition, when the first and second query words are Hangul, the number of syllables and letters match, but in the case of the alphabet, the number of syllables and letters may be different. Therefore, it is assumed that "syllable" includes the meaning of "letter". Let's explain.

An example in which each syllable of the first query is determined to be included in the second query in order by the syllable included relationship determining unit 120 is illustrated in FIG. 2. As shown, "Seoul City Symphony" is "Seoul Philharmonic Orchestra", "Shuju" is "Super Junior" and "Super Junior", "Music" is "Music Video", "Nation" is "Korea Lawyers Association", "Naver" can be seen that all syllables of the first abbreviation, such as "Junior Naver", are included in order in the second query, the original word.

In an embodiment, the first and second query words may be query words from which ASCII codes are removed. The syllable-containing relationship determining unit 120 determines whether each syllable of the first query is included in the second query in order, and removes alphabets, numbers, and special characters from the first and second query words. To judge.

In another embodiment, the syllable-containing relationship determining unit 120 may determine whether each syllable of the first question is sequentially included in the first syllable of each word of the second question. This is to determine whether the syllable includes each syllable when the first and second query words are alphabetized. For example, if the first query is "IBM" and the second query is "International Business Machines Corporation," each syllable of the first query, "I", "B", and "M", is each word of the second query. It can be seen that the first syllable of "I", "B", "M", and "C" are included in order.

Referring again to FIG. 1, when the substring determination unit 140 determines that each syllable of the first query is included in the second query in order by the inclusion relation determination unit 120, the first query Determine whether is a substring of the second query. If it is determined that the first query is not a substring of the second query, the second query is determined as a synonym of the first query, and the syllable comparison determining unit 142, the first synonym determination unit 144, And a word pattern determination unit 146 and a second synonym determination unit 148.

Here, determining whether the first query is a substring of the second query means determining whether all the strings of the first query are included in accordance with a part of the string of the second query. This is to determine whether or not the first query is a substring of the second query because the meaning of the word and the words side by side is limited, which is different from the original word.

An example in which the substring determination unit 140 determines that the first query is a substring of the second query is illustrated in FIG. 3. As shown, when the first query is "naver", "game", "patent" and the "second query" is "junior neighbor", "computer game", "patent law", the first query is the second query. It can be seen that this is the case of the substring, and in this case, since the meaning of the second query is limited by words other than the first query, there is a problem in determining the second query as a synonym of the first query.

In another embodiment, the substring determination unit 140 analyzes the morphemes of the first and second query terms and determines whether each morpheme of the first query is a substring of the second query. Here, determining whether each morpheme of the first query is a substring of the second query means at least one or more letters except for the morphemes corresponding to each morpheme of the first query in each morpheme of the second query. It is to determine whether it contains. This is to determine whether each morpheme of the first query is a substring of the second query because the second query has more limited morphology than the first query.

An example in which the substring determination unit 140 determines that each morpheme of the first query is a substring of the second query is illustrated in FIG. 4, and as shown, the first query is “strongly matched” and the second query is performed. When the query is "strongly matched," it can be seen that the morphemes of the first query "Kangho-dong", "correct" and are included in the morphemes of the second query, "strong-like", "god", "hit", In this case, since the second query has a more limited meaning than the first query, there is a problem in determining the second query as a synonym of the first query.

The syllable comparison determination unit 142 determines whether the first syllables of the first and second query words match each other, and the first synonym determination unit 144 determines the first and second query words by the syllable comparison determination unit 142. When it is determined that the first syllables of the words coincide with each other, the second query is determined as a synonym of the first query. Here, determining whether the first syllables of the first and second query terms coincide with each other is generally because the first syllables of the first and second query terms which are abbreviated are identical. Therefore, if the first syllables of the first and second query words do not coincide with each other, the syllable comparison determining unit 142 determines the second query as a synonym of the first query even if the first query is not a substring of the second query. I never do that.

An example in which the syllable comparison determining unit 142 determines that the first syllable of the first query and the second question does not coincide with each other is illustrated in FIG. 5. As shown, when the first query is "Dica" and the second query is "Canon Digital Camera", when the first query is "External" and the second query is "Korea University of Foreign Studies" First and second You can see that the first syllable of the query does not match.

Referring back to FIG. 1, when the syllable comparison determining unit 142 determines that the first syllables of the first and second query words do not coincide with each other, the second query word is a specific word pattern. If the second synonym determination unit 148 determines that the second query word starts with a specific word pattern by the word pattern determination unit 146, the second synonym determination unit 148 determines the second query word as a synonym of the first query word. Decide on Here, determining whether the second query starts with a specific word pattern is generally determined that the meaning of the second query is limited when the second query includes words such as "about", "Korea", "national", and the like. This is because it is difficult to do.

An example in which the second pattern is determined by the word pattern determination unit 146 to start with a specific word pattern is illustrated in FIG. 6, and as shown, the first query is "negotiation" and the second query is " Association of Korean Lawyers ", where the first question is" foreign "and the second question is" Korea University of Foreign Studies ", the first syllable of the first question and the second question does not match, but the second question is" Korean "and" Korea The second synonym determination unit determines the second query word starting with the word pattern as a synonym of the first query word.

Referring back to FIG. 1, the query filtering unit 160 determines a basic query among a plurality of second queries when there are a plurality of second queries determined as synonyms of the first query by the above-described substring determination unit 140. And removing a derivative, a variant, or a variant of the basic query, and includes a basic query determining unit 162 and a filtering unit 164.

The basic query determiner 162 determines the basic query from among the plurality of second queries when there are a plurality of second queries determined by the substring determination unit 140 as synonyms of the first query. According to an embodiment, when the first and second query terms are consecutively input query terms, the basic query determination unit 162 may continuously input the first query among a plurality of second queries determined as synonyms of the first query. The second query with the highest query count may be determined as the basic query. In this case, the second query may be continuously input after the first query is input. On the contrary, the first query may be continuously input after the second query is input.

For example, the second query determined as a synonym for the first query, "Shuju", may include a plurality of second queries such as "Super Junior", "Super Junior", "Super Junior", and "Super Junior Album". When the number of times a query is input consecutively as "Shuzhou" as the first query and "Super Junior" as the second query is the highest, "Super Junior" among the second queries may be determined as the basic query word.

 The filtering unit 164 removes at least one of a derivative of the basic query, a variant of the basic query, and a derivative of the variant from the plurality of second queries.

Here, a derivative word is a word derived from a basic query word, not a dictionary meaning of a dictionary meaning, and means a word in which other syllables are combined before or after the basic query word. It means the form is expressed differently according to.

Examples of derivatives, variants, and variants of the basic query term determined by the query filtering unit 160 are illustrated in FIG. 7, and as illustrated, the query query unit 160 is a basic query term among the plurality of second queries. Secondary queries such as "Super Junior", a variant of "Super Junior", derivative "Super Junior", and "Super Junior Album", a derivative of this form, can be removed.

As described above, the synonym determination unit according to an embodiment of the present invention determines a synonym of each query word through analysis of query words, and constructs a synonym database by matching and storing each query word determined as a synonym.

Hereinafter, a search service providing system using a synonym according to an embodiment of the present invention for providing a search service using the synonyms determined by the synonym determination unit described above will be described with reference to FIG. 8.

As illustrated, the search service providing system 600 using the synonym may include a synonym determination unit 100, a synonym database 200, a query receiving unit 300, a synonym determination unit 400, and a search result providing unit 500. Include.

As described above, the synonym determination unit 100 analyzes the query terms to determine the query terms in the abbreviation relationship as synonyms, and the synonym database 200 is determined by the synonym determination unit 100 to determine the first and the abbreviations. The second query is matched with a synonym and stored.

The search query receiver 300 receives a search query from a user, and the synonym determination unit 400 determines whether a synonym of the search query received through the search query receiver 300 exists in the synonym database 200. In other words, the search query determination unit determines whether a query that is abbreviated with the search query input by the user is stored in the synonym database 200 as a synonym. Therefore, if a synonym of the received search query is present in the synonym database, the synonym will be an abbreviation synonym of the search query if the search query is an abbreviation, or conversely if the search query is an abbreviation.

If there is a synonym of the received search query, the search result providing unit 500 includes a search result for the synonym of the received search query in the search result for the received search query. Accordingly, the search result providing unit 5000 may provide not only search results for the search query input by the user, but also search results having a synonym relationship with the input search query, thereby providing more accurate search results.

Although the synonym determination unit 100 is described as being included in the search service providing system 600 in the present embodiment, as mentioned above, the synonym determination unit 100 may not be included in the search service providing system 600. Could be In this case, the search service providing system 600 provides a search service using the synonym database 200 constructed by the synonym determination unit 100.

Hereinafter, a synonym determination method according to an embodiment of the present invention will be described with reference to FIG. 9.

First, the first question and the second question are determined (S700). In this case, the first and second query words may be consecutively input query words.

According to an embodiment, among the consecutively input query words, a query word having fewer syllables may be determined as the first query, and a query word having more syllables may be determined as the second query. Therefore, the first query may be determined by checking the number of syllables of the query, as well as the case where the number of syllables is input first as well as the number of syllables first. Therefore, the first query is a query word having fewer syllables than the second query word.

In an embodiment, the first and second query words may be query words from which ASCII codes are removed. This is to remove and determine alphabets, numbers, special characters, and the like in the first and second query words in determining whether each syllable of the first query is sequentially included in the second query in S710 to be described later.

Next, it is determined whether each syllable of the first query is included in the second query in order (S710). In an embodiment, it may be determined whether each syllable of the first query is included in order in the first syllable of each word of the second query. This is to determine whether the syllable includes each syllable when the first and second query words are alphabetized.

As a result of the determination, when each syllable of the first query is included in the second query in order, it is determined whether the first query is a substring of the second query (S720). This is to determine whether or not the first query is a substring of the second query because the meaning of the word and the words side by side is limited, which is different from the original word.

In an embodiment, the first and second query terms may be morphologically analyzed to determine whether each morpheme of the first query is a substring of the second query.

If it is determined that the first query is not a substring of the second query, it is determined whether the first syllables of the first and second query words coincide with each other (S730). When the first syllables of the first and second query terms coincide with each other, the second query is determined as a synonym of the first query (S740). In S730, it is generally determined whether the first syllables of the first and second query words coincide with each other because the first syllables of the first and second query words in the abbreviation relationship are the same.

Meanwhile, when the first syllables of the first and second query words do not coincide with each other in S730, it is determined whether the second query word starts with a specific word pattern (S750), and when the second query word starts with a specific word pattern, The second query is determined as a synonym of the first query (S740). Determining whether or not the second query begins with a specific word pattern in S750 generally means that the meaning of the second query is limited when the second query includes words such as “about,” “Korea,” and “national.” This is because it is difficult to do.

Next, when there are a plurality of second queries determined as synonyms of the first query, a basic query is determined from the plurality of second queries (S760), and a derivative of the basic query and a variant of the basic query among the plurality of second queries. And at least one of derivatives of this form (S770). According to an embodiment, when the first and second query terms are consecutively input query words, the basic query word may be determined as a query word having the highest query count input number among the plurality of second queries.

Finally, the synonym database is constructed by matching the first and second query terms with synonyms and storing the synonyms in the synonym database (S780). In other words, the query words that are abbreviated with the user input query words are determined as synonyms and stored in the database.

Hereinafter, a method of providing a search service using a synonym determined by using the synonym determination method described above will be described with reference to FIG. 10.

First, a search query is received from a user (S800), and it is determined whether a synonym of the received search query exists in the synonym database (S810). In other words, it is determined whether a query word which is abbreviated with a user input query word is stored in a synonym database as a synonym.

Next, when there is a synonym of the received search query, in providing a search result for the received search query, the search result for the received search query is included in the search result for the received search query. (S820). Accordingly, the search result for the search query input by the user as well as the search result for the synonym having a short relationship with the input search query can be provided together, thereby providing more accurate search results.

The search service providing method using the synonyms described above may be implemented in the form of program instructions that can be executed by various computer means, and recorded in a computer-readable recording medium. In this case, the computer-readable recording medium may include program instructions, data files, data structures, and the like, alone or in combination. On the other hand, the program instructions recorded on the recording medium may be those specially designed and configured for the present invention or may be available to those skilled in the art of computer software.
