Description

System and method for providing a related term using the dynamic ontology}

The present invention relates to a method and system for providing a related word using dynamic ontology. More specifically, when a search word is input, the search word is searched in related documents such as domestic or foreign law, precedent, and thesis. By extracting words other than nouns from the searched results, only nouns are extracted as common terms with frequency, and also, based on the legal terminology dictionary, legal terms are extracted with frequency and general terms whose frequency is higher. Negative dictionary and legal terms are applied to generate a certain number of general terms and legal terms as dynamic ontology, and the generated dynamic ontology has a certain number of general terms and frequencies that are lower than It is to provide a certain number of legal terms as related.

In general, a user using the Internet can use his computer to obtain desired information through many websites existing on the Internet. To do this, the user must know the address of a website that can provide the desired information, but in reality it is impossible to know a large number of addresses. Therefore, many search engines have been provided to enable a user to find a desired website (or web document) by a simple operation such as inputting only an index word.

Such search engines may be classified into directory search engines, robot search engines, and meta search engines according to their types. Directory search engines collect and process documents manually to build a database and supply collected data in response to user queries. Robot search engines are software search robots that collect and process web documents. Almost all search engines belong to this format. The meta search engine does not have its own search engine module, and provides searched data by using existing search engines.

In general, when a user enters a search command after entering a search word, addresses of a plurality of websites (or web documents) are provided to the user. Sometimes a short description is provided along with the address, and the user sees the content and tries to access the site. In addition, the user attempts to connect to the searched site until the user obtains satisfactory information. The user may waste a lot of time in this process to get the desired information.

On the other hand, even in the case of inputting the same search word, the content of the information to be originally searched may differ for each person according to the user's professional characteristics, desired expertise or taste. For example, using the index "home", if the user is an architect, a prospective buyer, a businesswomen, or a real estate agent, the content of the information required by each person will be different.

However, if the same search word is input, almost the same search data is provided regardless of the user's characteristics and personality as described above, and this also has an inefficient problem in that it takes a long time to obtain desired information.

According to the present invention for solving the above-mentioned problems, when a search word is input, the search term is searched in related documents such as domestic or foreign law, precedent, or thesis, and only the nouns are used as general terms by excluding words other than nouns from the search results. Extract the terminology together with the frequency based on the legal terminology from the searched results, and apply a negative dictionary to general terms and legal terms whose frequency is higher. The dynamic ontology is used to generate general terms and legal terms as dynamic ontology, and to provide a certain number of general terms whose frequency is lower than the common terms and legal terms with high frequency as related words in the generated dynamic ontology. It is an object to provide a method and system for providing related words.

According to an aspect of the present invention for achieving the above object, a method for providing a related word using a dynamic ontology of the system for applying the native language dictionary, the legal dictionary and the negative dictionary, comprising: (a) receiving a search word from a user; (b) searching for the search term in related documents in Korea and abroad; (c) collecting only nouns in common terminology with frequency, except for words other than nouns, based on the native language dictionary from the searched results; (c ') collecting legal terms with frequency based on the legal term dictionary from the searched results; (d) Except for the terms registered in the negative dictionary, a certain number of general terms in which the frequency corresponds to a preset general term high priority criterion and a predetermined number of regular terms in which the frequency corresponds to a preset high term legal criterion Collecting each legal term and generating a dynamic ontology; And (e) providing a predetermined number of general terms corresponding to a general term lower rank criterion having a predetermined frequency in the dynamic ontology, and providing a predetermined number of legal terms corresponding to a higher priority criterion set in frequency as a related word. A related word provision method using a dynamic ontology including a step may be provided.

In addition, in the step (b), the related document may include a law or statutes, precedents, academic papers, related legislation, foreign legislation, media articles, civil consultation documents, web documents, and the like.

In addition, in the step (b), the search term may be searched in the related document of the domestic, and the search term in which the search term is translated into the language of each country through a multilingual translator may be searched in the related document of the foreign country. .

In addition, the step (c) collects only nouns and compound nouns in the general term, except for words other than nouns, based on a Korean dictionary and a native language dictionary of each country, and the step (c ') is a domestic legal terminology dictionary. Korean legal terms and foreign language legal terms can be collected from the legal terminology dictionary of each country and the terms registered in the negative dictionary based on the negative dictionary can be excluded.

On the other hand, according to another aspect of the present invention for achieving the above object, an input unit for receiving a search word from a user; A language classifier for classifying the search word into Korean or a foreign language; A multilingual translator that translates the search term into a language of each country and provides the translated search term; A search unit for searching the search term in a domestic related document and searching the translated search term in an overseas related document; From the search result of the search unit, only the nouns are collected with the common term except the words other than the nouns in the Korean dictionary and the native language dictionary of each country, and the frequency of the legal terms based on the legal term dictionary from the search result of the search unit A term collecting unit to collect together; In the general terms and legal terms collected by the term collection unit, a predetermined number of general terms corresponding to the higher rank criteria, the frequency of which is preset, except for the terms registered in the negative dictionary, and the frequency in advance An ontology generation unit for collecting a predetermined number of legal terms corresponding to the set upper rank criteria and generating the dynamic ontology; And a related term for providing a predetermined number of general terms corresponding to a predetermined lower ranking criterion and a predetermined number of legal terms corresponding to a predetermined higher ranking criterion as a related word from the dynamic ontology generated by the ontology generator. A related language providing system using a dynamic ontology including a providing unit may be provided.

Here, the related document may include a law or a statute, a precedent, an academic paper, a related legal system, an overseas legislative case, a media article, a civil consultation document, a web document, and the like.

The term collection unit collects only nouns and compound nouns in the general term by applying words other than nouns in the Korean dictionary and the native language dictionary of each country, and the Korean legal terminology and the Korean legal terminology dictionary and the legal terminology dictionary of each country. Foreign language legal terms may be applied to collect the legal terms and exclude terms registered in the negative dictionary based on the negative dictionary.

According to the embodiments of the present invention, when a user inputs a search word to obtain desired information, the user presents a related word related to the search word, and thus, the user selects a related word that is most closely related to the desired information among the suggested related words. The desired information can be obtained quickly.

Further, in addition to the desired information, additional information related to the search word may be additionally obtained through related words related to the search word for obtaining the desired information.

In addition, the related term (The Term in Thesaurus) is a word or phrase indicating key words that are related to each other for information retrieval in the thesaurus. In the present invention, the term refers to a word or phrase indicating key words that are related to a search word input from a user. .
In addition, the meaning of the upper and lower order means that they are sequentially listed according to a predetermined upper rank criteria or a predetermined lower rank criteria, each included in the preset ranking. In this case, each of the upper rank criteria and lower rank criteria may be separately set according to general terms and legal terms.
In addition, an inappropriate term means terms registered in a negative dictionary.

1 is a block diagram showing a functional block of a related language providing system using a dynamic ontology according to an embodiment of the present invention.

Referring to FIG. 1, the related language providing system 100 according to the present invention includes an input unit 110, a language classifier 120, a multilingual translator 130, a search unit 140, a term collection unit 150, and an ontology generation. The unit 160, the related word providing unit 170, and the search information database 180 may be included.

The input unit 110 receives a search word from a user.

The language classifier 120 classifies a search word into Korean or a foreign language.

The multilingual translator 130 translates a search word into a language of each country and provides the translated search word. For example, when the search term is 'law', the multilingual translator 130 may provide the translation search term 'law'.

The search unit 140 searches for a search term in a domestic related document and searches for a translation search term in a foreign related document.

Here, the related document may include a law or a statute, a precedent, an academic paper, a related legal system, an overseas legislation, a press article, a civil complaint document, a web document, and the like.

The term collecting unit 150 collects only the nouns in general terms together with their frequency, excluding words other than nouns from the Korean dictionary and the native language dictionary of each country, from the search result of the search unit 140.

In addition, the term collecting unit 150 collects legal terms with a frequency based on a legal term dictionary from the search result of the searching unit 140.

In this case, the term collection unit 150 collects only nouns and compound nouns in general terms except words other than nouns in the Korean dictionary and the native language dictionary of each country. Terms and foreign language legal terms can be collected as legal terms.

Ontology generation unit 160 is a general number and the common terms collected by the term collection unit 150, a certain number of frequencies that the upper frequency, that is, 50 general terms, and a frequency corresponding to the upper A number, that is, 30 legal terms are collected, and the negative dictionary is applied to generate the terms except for the terms registered in the negative dictionary as dynamic ontology. According to an embodiment of the present invention, a negative dictionary is applied to a predetermined number of general terms having a high frequency and a predetermined number of legal terms having a high frequency through the above-described process. Data collected from terms other than registered terms is defined as 'dynamic ontology'.

The relational word providing unit 170 may have a predetermined number of frequencies corresponding to a lower frequency, that is, four general terms and a predetermined number of frequencies corresponding to a higher frequency, that is, six legal terms from the dynamic ontology generated by the ontology generator 160. Provide them as relevant.

The search information database 180 is a data for search, and includes a database that provides laws, laws, precedents, academic papers, related legislation, media articles, and civil counseling documents. For example, a database providing legal information. It can be provided in the form of a separate database such as a database providing case information and a database providing article information.

In addition, the search information database 180 may also include a database storing corresponding words obtained as a result according to an embodiment of the present invention corresponding to the search word.

In addition, the search information database 180 is displayed in a single database form as shown in FIG. 1, but provides laws, statutes, precedents, academic papers, related laws, media articles, and civil counseling documents in Korea and overseas. It contains a database.

2 is a flowchart illustrating a related word providing method using dynamic ontology according to an embodiment of the present invention.

Referring to FIG. 2, the related word providing system 100 according to the present invention first receives a search word, for example, a 'compensation for damage' from the user through the input unit 110 (S202).

Subsequently, the related-language providing system 100 discriminates whether the foreign language or the Korean language is received through the language classifier 120 with respect to the input search word (S204).

Subsequently, the related language providing system 100 translates the search word into a language of each country through the multilingual translator 130 (S206). Here, the multilingual translator 130 may be, for example, a translator of a Google site or a translator of an ontorus.

Subsequently, the related-language providing system 100 searches for a Korean search word from a domestic related document (S208a), or searches for a translated search word from a foreign related document (S208b).

Here, the related document may include a law or a statute, a precedent, an academic paper, a related legal system, an overseas legislation, a press article, a civil complaint document, a web document, and the like.

In this case, when the related word providing system 100 searches a search word through the search unit 140, the search word is searched from the search information database 160 regarding domestic laws, precedents, articles, or the like, or the search term is searched by the multilingual translator 130. You can collect the search results from the database server of the corresponding country by sending the translated search word translated into the language of each country to a database server that provides other external (or overseas) laws, precedents, or thesis connected to the communication network. have.

Subsequently, the related word providing system 100 obtains a search result including a search word among domestic laws, precedents, and articles (S210a), or obtains a search result including a search word among foreign laws, precedents and articles (S210b).

Subsequently, the related language providing system 100 extracts only nouns (composite nouns) as general terms except words other than nouns in the Korean dictionary based on the Korean dictionary (S212a).

In addition, the related-language providing system 100 extracts only nouns (composite nouns) as general terms, except for words other than nouns, from the native-language dictionaries based on the native-language dictionaries of each country (S212b).

Subsequently, the related language providing system 100 collects general terms extracted based on the Korean dictionary and general terms extracted based on the native language dictionary of each country together with the frequency through the term collection unit 150 (S214a).

Meanwhile, the related term providing system 100 extracts Korean legal terminology through a search matched in a legal terminology dictionary, based on a legal terminology dictionary, from a search result including a search word obtained from domestic law, precedents, and thesis (S212c).

In addition, the related-language providing system 100 extracts a foreign language terminology from a search result including a search word obtained from overseas law, precedents, and thesis through a search matched with a legal terminology dictionary of each country (S212d).

Subsequently, the related term providing system 100 collects the Korean legal terms extracted based on the domestic legal terminology dictionary and the foreign language legal terms extracted based on the legal terminology dictionary of each country together with the frequency through the term collecting unit 150 ( S214b).

Subsequently, the related word providing system 100 excludes the terms registered in the negative dictionary by applying a negative dictionary from general terms and legal terms collected by the term collecting unit 150, and then, based on the related term, the frequency A certain number corresponding to the upper level, for example, 50 general terms and the top 30 legal terms are collected (S216), respectively (when each of the predetermined general term high rank criteria is 50 and the preset legal term high rank criterion is 30). In operation S218, the ontology generator 160 generates the dynamic ontology.

Subsequently, the related word providing system 100 uses the related word providing unit 170 in a certain number of frequencies corresponding to a lower frequency in the dynamic ontology, for example, four general terms and a predetermined number corresponding to the upper frequency. For example, six legal terms are provided as related words as shown in FIG. 3A (S220).

3 is a view showing an example of providing the lower four general terms and the upper six legal terms according to the frequency of a related word related to a search word input from a user according to an embodiment of the present invention. As shown in FIG. 3, the related word related to the term "compensation for damages", "duty of attention", "compensation for fault", "claim for damages", "compensation for damages", "traffic accident" depending on the frequency of use thereof It provides ten related terms such as "Extinctive Prescription", "Automobile Compensation Guarantee Act", "Loss Loss", "Cause", and "Debt default".

As described above, according to the present invention, when a search word is input, the search term is searched in related documents such as domestic or foreign laws, precedents, and thesis, and only words are searched in general terms by excluding words other than nouns from the search results. Extract the terminology together with the frequency based on the legal terminology dictionary from the searched results, and apply a negative dictionary to the general terms and legal terms with the highest frequency And a related term using a dynamic ontology, which generates a legal term as a dynamic ontology, and provides a predetermined number of general terms whose frequency is lower and a certain number of legal terms whose frequency is higher in the generated dynamic ontology as related words. The provision method and system can be realized.
