<System overview>

Hereinafter, a system according to an embodiment of the present invention will be described in detail with reference to FIG.

The system according to an embodiment of the present invention includes a user terminal 100, a terminology conversion server 200, a general terminology / legal term matching database 300, and a precedent server 400.

When the user inputs a phrase or sentence related to a predetermined event such as civil / criminal / intellectual property right through the user terminal 100, the user terminal 100 transmits the corresponding phrase or sentence to the term conversion server 200 .

The terminology conversion server 200 extracts general terms from the received phrase or sentence, and converts the extracted general term into a legal term by referring to the matching database 300.

Then, the term conversion server 200 searches the precedent cases including the converted legal terms out of precedent cases stored in the precedent server 400, and provides the retrieved results to the user terminal 100. The precedent server (400) may be a legal entity server, such as a Supreme Court, a local court, or a high court website server.

As described above, since the user simply inputs a general term to be used, the server automatically converts it into a legal term and provides a case search result. Therefore, the user can easily find the case You can search for the case you want quickly and easily.

<Case search device (server)>

Hereinafter, with reference to FIG. 2, a configuration of a case search apparatus through automatic conversion between general terms and legal terms according to an embodiment of the present invention will be described in detail.

The case search apparatus may refer to the term translation server 200 of FIG. 1, but may include a term translation server 200 and a general term / legal term matching database 300 (hereinafter referred to as a "matching database" It can also mean a server.

First, a method for constructing the matching database 300 will be described in detail.

The matching database 300 stores a matching table that defines the correspondence between general terms and legal terms. At this time, the matching relation between the general term and the legal term constituting the matching table can be specified by directly inputting by the server manager.

However, the present invention is not limited to this, and may be configured to automatically store a matching relation between a general term and a legal term through a crawl of a Web document. In particular, the matching database 300 can crawl any web document and extract and match common terms and legal terms contained within each web document. For example, a blog page including a civil case and a case content can be crawled, and general terms and legal terms included in the blog page can be extracted and stored in a matching manner.

As a further embodiment, the matching database 300 extracts general terms and legal terms contained in each web document, and then refers to a dictionary server (not shown) It is possible to extract a definition sentence and to match and store a general term and a legal term that have a high degree of similarity between the extracted definition sentences. For example, if the terms "landlord" and "landlord" are extracted from a web document, the dictionary server may request definitions for the terms "landlord" and "landlord", and the term "landlord" If the number of matching words among the words included in the defining sentence is equal to or greater than a preset number, the "landlord" and the "landlord" can be matched and stored.

On the other hand, the matching between the general term and the legal term defined in the matching table can be defined as 1: 1 correspondence. For example, the legal term for a generic term "landlord" can be matched to a single term "landlord".

As a further example, a match between a general term and a legal term may be defined in correspondence with 1: n (n> 1, where n is an integer). For example, several legal terms such as "charterer", "tenant" may be matched for the generic term "tenant". In this case, for each legal term, different matching weights may be applied depending on the degree of similarity between general terms and legal terms. Here, the matching weight means a score indicating the degree of matching between the general term and the legal term. For example, different matching weights may be applied depending on the similarity of the definition sentences of the "charter particle-tenant" pairs and the similarity of the definition sentences of the "tenant-tenant" pairs.

Further, as a further embodiment, when additional web documents are crawled and additional pairs of common terms and legal term pairs stored in the matching table are additionally detected, different or identical matching weights may be applied depending on the number of additional detection have. For example, a higher matching weight may be applied if the web document containing the "tenant-tenant" pair has more web documents containing the "tenant-charter particle"

Further, as a further embodiment, a match between a general term and a legal term may be defined in correspondence with n: 1 (n> 1, n is an integer). For example, common terms such as "landlord", "landlord", "landlord", etc. may be matched with one legal term "landlord". In this case, when a plurality of words having similar or overlapping meanings are used in the phrase or sentence inputted by the user, it can be converted into a smaller number of legal terms than the number of extracted general terms, The number of legal terms is reduced, and a highly efficient search can be made.

On the other hand, the terminology conversion server 200 may include a memory for storing a program (or an application) for case search and a processor for executing the program. At this time, the processor can perform various functions according to the execution of the program stored in the memory, and the detailed modules included in the processor according to each function are stored in the user input information receiving unit 210, the general term extraction unit 220, Unit 230, a legal term conversion unit 240, and a case search unit 250.

The user input information receiving unit 210 receives a phrase or sentence including at least one word input by the user from the user terminal 100. [ For example, the user can enter a sentence such as "The landlord does not return the deposit, what should I do?"

The general term extraction unit 220 extracts at least one general term from the received sentence or sentence. For example, the general term extraction unit 220 may extract words such as "landlord", "deposit", "return", "not" from the sentence.

The category classification unit 230 can search the category for the sentence or phrase based on the extracted general term. The category classification unit 230 may transmit the category information to the legal term conversion unit 240. For example, the category classification unit 230 may designate a category related to the lease contract based on general terms such as "landlord" and "deposit " At this time, the legal term conversion unit 240, which will be described later, may match the legal term corresponding to the general term from a plurality of legal terms stored in the category designated by the category classification unit 230. [

On the other hand, the category classification unit 230 searches the category of the sentence or phrase based on the legal term converted by the legal term conversion unit described later, and converts the converted legal term among a plurality of precedents included in the searched category Or by searching for a precedent that includes. That is, the category classification unit 230 may be utilized for narrowing the search range so that it is easy to search for a legal term or a case search.

The legal term conversion unit converts each extracted at least one general term into at least one legal term. As noted through the matching database 300, the legal terminology translator can translate the generic term: legal term into a corresponding relationship such as 1: 1, 1: n or n: 1 (n> 1, n is an integer) have.

Here, if there are a plurality of legal terms corresponding to one general term, the legal term conversion unit can provide all of a plurality of legal terms as a result value. Alternatively, the legal term conversion unit may provide a legal term having the highest matching weight as a result value according to the above matching weight among a plurality of legal terms, or may be a predetermined number (two or three) Of the legal terms of the term.

The precedent retrieving unit 250 retrieves precedents including at least one legal term that has been converted, and provides information on the precedent retrieved by the user terminal 100. The precedent retrieving unit 250 can retrieve the precedent from the precedent server 400 existing outside the term conversion server 200. [ However, if the case database exists in the terminology conversion server 200, the case translation server 200 may process the case search process.

The case search unit 250 searches the precedent case including all the converted legal terms and transmits information about the precedent case (that is, the case number of the precedent case, the case name of the precedent case, the order of the precedent case, etc.) to the user terminal 100 .

As a further example, the precedent retrieval unit 250 may evaluate the score for each precedent based on at least one of the number of legal terms included in each precedent among the converted legal terms and the frequency that appears within the precedent for each legal term . And may provide the user terminal 100 with a list of information of precedents in the order of the highest evaluated score. For example, if the converted legal term is "Tenant", "Deposit" or "Default", the first case includes "Tenant", "Deposit" and "Default" Tenant "or" deposit ", the first case may be provided in a higher order than the second case. As another example, in the first case, the frequency of appearance of "Tenant", "Deposit" and "Default" is [3 times, 4 times, 4 times]. In the second case, "Tenant", "Deposit" If the frequency of occurrence of "default" is [once, twice, once], the first case may be arranged higher than the second case.

In addition, as a further embodiment, the case search unit 250 evaluates the score for each precedent in consideration of the matching weight of the legal terms included in each precedent, Or may be provided to the terminal 100. For example, if the converted legal term is "charterer", "tenant" exists for the general term "tenant" and the matching weight of "tenant" is higher than the matching weight of "charterer" The score of the case containing the term can be evaluated higher. Alternatively, the score of the higher frequency case where the term "tenant" appears may be higher.

Meanwhile, as a further embodiment, the term conversion server 200 receives the fitness score of the information about the case from the user terminal 100, and when the fitness score is equal to or higher than a preset score, Lt; RTI ID = 0.0 &gt; term &lt; / RTI &gt; That is, the matching weight may be defined in advance when generating the matching table for the general term and the legal term, but the matching weight may be defined through the feedback information received from the user after providing information on the precedent.

The term conversion server 200 searches the category of the case provided by the user terminal 100 and transmits information of the legal experts stored in the term conversion server 200 to the user terminal 100 in association with the category It is possible. The information of the pre-stored legal professional may be the information of the legal professional who paid the advertisement cost to the server manager.

That is, the case search apparatus according to an embodiment of the present invention extracts general terms from general sentences or phrases inputted by a user as shown in FIG. 3, converts the extracted general terms into legal terms, Thus, the user can easily and quickly retrieve desired precedents. At this time, it is possible to perform highly accurate case search targeting because it searches for cases based on general terms and corresponding legal terms.

<Case search method>
