The associated law: the related law that the content regulated by the law has relevance is meant. The law management system comprises a highest people's court, judicial explanations, instruction documents and the like about the specific application of the law, which are made by the highest people's court aiming at basic legal documents made by legislation authorities, and the law with higher frequency is usually referred to when a certain part of law is applied in the trial practice.
In the conventional legal and legal retrieval method, if a more accurate result is to be obtained, a certain legal knowledge is required, and a more complex retrieval formula is required to be edited, so that a relatively accurate retrieval result can be obtained. The following describes embodiments of the present invention in detail.
The embodiment of the invention discloses a retrieval method of laws and regulations.
Referring to fig. 1, fig. 1 is a schematic flow chart of a retrieval method of laws and regulations disclosed in the embodiment of the present invention.
The invention provides a retrieval method of laws and regulations, which comprises the following steps:
s100, obtaining keywords;
s200, judging whether the keywords belong to legal entity nouns or not;
s300, if the keyword belongs to a legal entity noun, judging the legal entity type of the keyword, and searching a legal regulation database according to a search dimension corresponding to the legal entity type to obtain a first search result; the legal entity type comprises any one of legal name, legal number and legal title;
s400, if the keyword does not belong to legal entity nouns, performing fuzzy retrieval after performing accurate retrieval on the keyword in the legal and legal regulation database to obtain a second retrieval result;
and S500, displaying the first retrieval result or the second retrieval result.
In the embodiment of the present invention, in step S100, a keyword is obtained. The keywords refer to keywords input by a user or keywords transmitted from other systems.
In actual use, the keywords are, for example: min Zhi Fang, explain No. 2015 to 21, the chairman command No. five, and intentionally injure.
In step S200, it is determined whether the keyword belongs to a legal entity noun.
The term "entity" refers to an entity having a specific meaning in the legal field mentioned or covered by the meaning in the specification text such as laws, regulations, judicial explanations, departmental regulations, normative documents and the like which are formulated and published by the country, and mainly includes legal names, legal provisions, case/crime names and legal letters.

In the embodiment of the present invention, step S200 specifically includes:
determining whether the keyword includes a non-legal noun;
if the legal nouns are included, matching the keywords in a standard legal noun mapping library to obtain a matching result representing the standard legal name;
and when the matching result is matched with the legal entity noun in the legal entity noun database, determining that the keyword belongs to the legal entity noun.
In the embodiment of the invention, whether the keyword comprises the illegal nouns or not is determined, and if the keyword comprises the illegal nouns, the keyword is matched to obtain a matching result.
For example, the national complaint law is mapped to the national consensus litigation law.
And determining whether the name belongs to the legal entity name or not, and searching in two directions respectively to ensure the searching precision to the maximum extent.
After determining that the keyword belongs to a legal entity noun, in step S300, the legal entity type of the keyword is determined, and the legal and regulatory database is retrieved according to the retrieval dimension corresponding to the legal entity type.
The legal entity type can include any one of legal name, legal number and legal title. And searching under the corresponding dimensionality of each legal entity type to obtain an output result. In the embodiment of the invention, after the legal entity type corresponding to the keyword is confirmed, the retrieval can be carried out more pertinently, so that the obtained result is more in line with the real intention of the user. Moreover, corresponding contents can be retrieved according to the retrieval dimensionality corresponding to the keyword without setting too many retrieval formulas by a user, and the learning cost is reduced.
And if the keyword belongs to the legal entity noun, performing fuzzy retrieval after performing accurate retrieval on the keyword in the legal regulation database to obtain a second retrieval result.
In the embodiment of the invention, if the determined keyword does not belong to the legal entity noun, the fuzzy matching is carried out after the accurate matching is preferentially carried out, the query result obtained by the accurate matching is preferentially displayed, and the query result obtained by the fuzzy matching is displayed after the query result obtained by the accurate matching is preferentially displayed.
In addition, in the embodiment of the invention, the weight of the retrieval dimension is preset, and the matching is carried out according to the weight of the retrieval dimension. And the retrieval efficiency is improved.
After the first search result or the second search result is searched, in step S500, the first search result or the second search result is displayed.
In the embodiment of the present invention, the presentation refers to a graphical interface provided to a user or presentation data returned to a system, and the presentation process is not described herein in detail, and is not limited herein as long as presentation can be performed.
It can be seen that the retrieval method of laws and regulations provided by the application firstly obtains key words; then judging whether the keyword belongs to a legal entity noun or not; if the keyword belongs to the legal entity noun, judging the legal entity type of the keyword, and searching a legal regulation database according to the search dimension corresponding to the legal entity type to obtain a first search result; if the keyword does not belong to legal entity nouns, performing fuzzy retrieval after performing accurate retrieval on the keyword in the legal regulation database to obtain a second retrieval result; and finally, displaying the first retrieval result or the second retrieval result. Therefore, the embodiment of the invention can realize inquiry of various dimensions through legal entity terms, can obtain relatively accurate retrieval results without setting too many complicated retrieval formulas and paying higher learning cost, and greatly improves the retrieval precision and the retrieval efficiency.
In the foregoing embodiment, the legal entity type is introduced, and in the embodiment of the present application, the legal entity type is identified.
In the embodiment of the present invention, the determining the legal entity type of the keyword includes:
if the keyword is matched under the legal name field in the legal regulation database, determining that the legal entity type of the keyword is a legal name;
if the keyword is matched under the legal document number field in the legal and legal regulation database, determining that the legal entity type of the keyword is a legal document number;
and if the keyword is matched in case or criminal name fields in the law and regulation database, determining that the legal entity type of the keyword is the main idea of the law.
In the embodiment of the invention, the legal entity types of the keywords can be divided into: legal title, legal number, and the gist of the act.
The data in the law and regulation database is provided with a plurality of fields, such as legal names, legal number and legal gist, and certainly, the data also comprises fields such as legal content and the like.
In the embodiment of the invention, if the keyword is matched under the legal name field in the legal regulation database, for example, the national complaint law, the people's republic of China civil action law, the legal entity type of the keyword is determined to be the legal name.
Similarly, if the keyword is matched under the legal number field in the legal regulation database, the legal entity type of the keyword is determined as the legal number. And if the keyword is matched under the case or crime name field in the law and regulation database, determining that the legal entity type of the keyword is the main idea of the law and regulation.
It can be understood that other legal entity types and corresponding retrieval dimensions may also be included, and only the retrieval method for the legal entity type and the retrieval dimension needs to be set, which is not described herein again.
In the foregoing embodiment, the process of retrieving the legal data database according to different retrieval dimensions to obtain the first retrieval result is described, and the following describes the retrieval process of different retrieval dimensions in detail.
In the technical solution of the present invention, when it is determined that the legal entity type is a legal name, the retrieving the legal and regulatory database according to the retrieval dimension corresponding to the legal entity type to obtain the first retrieval result includes:
converting the keyword into a legal standard name;
inquiring the laws and regulations with the legal name fields as the legal standard names in the laws and regulations database, and sequencing the obtained laws and regulations according to the sequencing rule of the published date to obtain a first inquiry result;
inquiring the law and judicial interpretation which accord with the association rule with the standard legal name to obtain a second inquiry result;
and integrating the first query result and the second query result to obtain a first retrieval result.
In the embodiment of the invention, if the legal entity type is the legal name, the keyword is converted.
For example, the conversion operation is realized by establishing a thesaurus and an extended thesaurus.
The synonym library and the expansion lexicon can be compatible with common error expressions, stroke errors, tone words and the like of the public to convert the keywords into legal standard names.
And then, searching under the dimension of the legal name field, if the searched unique value is the unique value, directly using the unique value as a first query result, and if the unique value is a plurality of values, sequencing the unique value from near to far according to the publication date.
In actual use, for example, if the input keyword is "national complaint", the keyword is first converted into a legal standard name "the national consensus and national litigation", and if there are a plurality of results corresponding to the keyword in the legal name field of the legal database, the sorted result is used as the first query result.
Taking the above-mentioned "national complaint" as an example, the first query result is:
litigation method for people in the people's republic of China (2017 amendment)
Litigation method for people in common people (2012 amendment)
Litigation method for people in common people (2007 amendment)
Litigation method for people in the people's republic of China
Then, the law and judicial interpretation which are in accordance with the association rule with the standard legal name are inquired, and other legal documents which are closely related to the standard legal name are displayed.
For example, the association matching can be performed based on the text similarity of the standard law, based on other legal names mentioned throughout the law, and the like.
In practical use, the laws associated with the first query result may include:
explanation of the highest people's court about the application of the litigation of people's republic of China
Interpretation of the highest national court for several problems in the procedure adopted by the national litigation of people's republic of China
Explanation of several problems of the judgement supervision program of the highest people's court about being suitable for the people's republic of China litigation law
In the embodiment of the invention, the first query result is arranged in front of the second query result, and the second query result is arranged behind the first query result and is integrated into the first retrieval result for display.
That is to say, in the embodiment of the present invention, the returned first search result is not simply matched with the legal document, but is displayed in a centralized manner based on the association of the legal system, so that the user can refer to more bases during the search.
For example, when a judge judges a case, a keyword can be input to obtain a plurality of results related to the keyword, so that the judge can conveniently search the basis of the case.
In the embodiment of the present invention, after determining that the legal entity type is a legal name, the method may further include:
determining whether the keyword includes a legal provision;
when the keyword is determined to include the legal provision, obtaining a first search result includes:
integrating the standard legal name and the legal provision into a legal inquiry parameter;
and inquiring the law and regulation database by taking the law and regulation inquiry parameter as a basis, and taking the output law and regulation content as a first retrieval result.
In the embodiment of the invention, legal terms may be attached to the legal names of the keywords. Such as article 22 of criminal law. If the legal entity type of the keyword is determined to be a legal name, on the basis, whether legal provision is included is determined. Wherein, the number in the legal provision can be Arabic number or capital number. The first retrieval result is specific clause content.
In actual use, for example:
and inputting the fifty-fifth of the national complaint, identifying the national complaint, matching the national complaint with corresponding national complaint, and displaying the content of the fifty-fifth of the national complaint in the display content.
Fiftieth XXX of China's republic of people litigation (2017 amendment)
Fiftieth XXX in the litigation of people's republic of China (2012 amendment)
Fiftieth XXX in the litigation of people's republic of China (amendment 2007)
Article 55 XXX of the litigation of people's republic of China
Wherein XXX represents the content of the French statute.
It can be understood that if the legal provision followed by the legal name is not in the legal regulation corresponding to the legal name, the first search result may be directly returned.
In actual use, for example, if the first thousand of the national complaint is input, the national complaint is recognized, but the first thousand of the national complaint is not input, the word interference of the first thousand of the national complaint is ignored, and the relevant query result of the national complaint is directly returned.
In the embodiment of the invention, the retrieval can be carried out in the dimension of the legal name, the legal rules under the dimension can be accurately obtained, the popular legal concepts can be connected and matched with professional legal provisions, and the actual retrieval intention of the user can be better met in actual use.
In the embodiment of the present invention, when it is determined that the legal entity type is a legal number, the legal and regulatory database is retrieved according to the retrieval dimension corresponding to the legal entity type, and the obtaining of the first retrieval result includes
Inquiring the laws and regulations with the legal number fields as the key words in the laws and regulations database to obtain a third inquiry result;
and sequencing the laws and regulations in the third query result according to the sequencing rule of the effectiveness grade to obtain a first retrieval result.
When the legal entity type is determined to be the legal number, in the embodiment of the invention, accurate retrieval is carried out under the dimensionality of the legal number to obtain a third query result.
And sorting according to the effectiveness grades, and when the effectiveness grades are the same, sorting according to the sequence of the publication dates from near to far.
In actual use, for example, "chairman command fifth of the people's republic of china" is input, the first search result is:
fifth place of the president of the people's republic of China-hero blast protection method of the people's republic of China
Grassland method of the people's republic of China (2013 amendment)
Coal method of the people's republic of China (2013 amendment)
Infectious disease prevention and treatment method of the people's republic of China (2013 amendment)
The great Committee of the people all over the country about the decision to modify twelve laws of the protection Law of the Chinese characters' republic of China (2013)
According to the technical scheme, accurate retrieval can be performed under the dimensionality of the legal number, so that an accurate query result is obtained, a retrieval mode is not required to be set, and the identification process is automatically completed.
In the embodiment of the present invention, when it is determined that the legal entity type is a case name or a crime name, the retrieving the legal regulation database according to the retrieval dimension corresponding to the legal entity type to obtain the first retrieval result includes:
inquiring the laws and regulations of which the law and regulation main field comprises the key words in the laws and regulations database to obtain a fourth inquiry result;
and sequencing the laws and regulations in the fourth query result according to a basic sequencing rule to obtain a first retrieval result.
In the embodiment of the invention, the retrieval is also carried out under the dimensionality of the law enforcement gist, wherein if the legal entity type is a case or crime name, the accurate query is carried out under the field of the law enforcement gist to obtain a fourth query result.
For example, if "intentional injury" is entered, matching is performed under the "main subject of law" field, and the hit laws and regulations are listed in the front.
And sorting according to the basic sorting rule.
In the embodiment of the present invention, a basic sorting rule is set, wherein the basic sorting rule may specifically be:
the national regulation is arranged in front of the local regulation;
high efficacy grade is ranked ahead of low efficacy grade;
arranging the high-timeliness in front of the low failure performance;
the timeliness is from high to low: active > modified > not yet validated > partial fail > fail;
fourthly, the date of implementation is prior recently;
fifth, the publication date is most prior;
of course, other sequencing contents may also be included, and the setting may be performed according to actual needs, which is not described herein.
In the embodiment of the invention, a process of obtaining the second retrieval result is mentioned.
Specifically, the step of performing fuzzy retrieval after performing accurate retrieval on the keyword in the law and regulation database to obtain a second retrieval result includes:
accurately inquiring in the law and regulation database according to the retrieval sequence of the title, the main theme of the law, the law provision and the full text of the law in sequence to obtain a fifth inquiry result;
performing word segmentation operation on the keywords to obtain a plurality of word segmentation parameters, and performing fuzzy query on the plurality of word segmentation parameters in the legal regulation database according to the retrieval sequence of which the retrieval fields are titles, legal essences, legal provisions and full legal texts in sequence to obtain a sixth query result;
and sequencing the laws and regulations in the fifth query result and the sixth query result according to a basic sequencing rule to obtain a second retrieval result.
In the embodiment of the invention, if the name is determined not to belong to the legal entity name, the accurate search is executed firstly.
The accurate retrieval is to sequentially perform retrieval according to the following dimension sequence: title > main theme of law > statute article > full text of law, obtain the fifth inquiry result.
And then, performing fuzzy retrieval, wherein in the embodiment of the invention, the fuzzy retrieval refers to performing word segmentation on the keywords and then performing retrieval according to the dimension sequence.
For example, the word segmentation result is input as "commonweal litigation", the word segmentation result is input as "commonweal" and "litigation", and the word segmentation result is searched once according to the above dimensional sequence.
