Description

A kind of judicial class case searching system and its search method

Technical field

The present invention relates to data retrieval technology field, specifically a kind of judicial class case searching system and its retrieval side Method.

Background technology

During the handling of some difficult cases, judicial functionary is in addition to by own service knowledge and experience, warp Often need to retrieve the history case (i.e. judicial class case) similar with pending case, to hold the processing of related merit, in center pass In under the requirement of " strengthening and specification judicial explanation and case guidance, unified law applied code ", the class case of precise and high efficiency is retrieved Active demand as judicial functionary.

The text retrieval system based on keyword the most universal is applied in existing judicial class case retrieval technique, it is accurate in retrieval True property and professional upper it can not meet user and require to find out its cause, can be summarized as three aspects：The domain knowledge of administration of justice without Method in full express by searching system；The key concept case " central issue " of class case can not be summarized with keyword；Administration of justice The complex logic of " ultimate facts " is difficult to crucial word description.

The content of the invention

The invention aims to solve the low defect of the professional poor, degree of accuracy of the prior art, there is provided one kind department Method class case searching system and its search method solve the above problems.

To achieve these goals, technical scheme is as follows：The invention discloses a kind of judicial class case retrieval system System, including input module, inquiry parsing module, retrieval performing module, sort recommendations module, output module, described input mould Block is used to supply user input query content, and described inquiry parsing module is used to parse the inquiry content of user, obtained The type of the inquiry content, described retrieval performing module is used for the type according to the inquiry content, from judge's knowledge graph The ultimate facts is obtained in spectrum, the judge's case associated by case marker library searching with the ultimate facts, described row Sequence recommending module is used to carry out judge's case that retrieval is obtained integrated ordered recommendation, and described output module is used for the exhibition of result Show output.

Preferably, the method that described inquiry parsing module can calculate similarity using COS distance,D values are bigger, and explanation similarity is higher.

Preferably, described sort recommendations module specific algorithm can examine order models using evidence, first to method The true foundation vector F=(f1, f2 ..., fn) of the corresponding dispute of principle is restrained, and ultimate facts is carried out to each class case found Evidences collection, sets up vector P=(p1, p2 ..., pk), common factor is taken to F and P, it is assumed that be (g1, g2 ..., gm), then evidence is obtained Point, score=g1* weights (g1)+g2* weights (g2)+...+gm* weights (gm), weight is the weight of each evidence, it is necessary to pre- First it is ready to.

Preferably, the invention also discloses a kind of above-mentioned search method of judicial class case searching system, specific steps are such as Under：

(1), user passes through input module input inquiry content；

(2), inquiry parsing module is parsed to the inquiry content of user, obtains the type of the inquiry content；

(3) ultimate facts, is obtained from judge's knowledge mapping by retrieval performing module, passes through case marker library searching The judge's case associated with the ultimate facts；

(4), judge's case that retrieval is obtained is carried out by sort recommendations module integrated ordered；

(5) user, is recommended by output module.

The present invention has advantages below compared with prior art：

The present invention constructs judge's knowledge mapping and " striven to describe case from the domain business knowledge system of administration of justice The concept such as view focus " and " ultimate facts ", the central issue and ultimate facts of case is obtained by judging knowledge mapping, to specific Judge's case carries out class case retrieval, and integrated ordered to retrieval result progress, greatly improves the accuracy and specialty of class case retrieval Property.

Embodiment

To make to have a better understanding and awareness to architectural feature of the invention and the effect reached, to preferably Embodiment and accompanying drawing coordinate detailed description, are described as follows：

As Figure 1-3, the invention discloses a kind of judicial class case searching system, including input module 1, inquiry parsing mould Block 2, retrieval performing module 3, sort recommendations module 4, output module 5, described input module 1 are used for in user input query Hold, described inquiry parsing module 2 is used to parse the inquiry content of user, obtain the type of the inquiry content, institute The retrieval performing module 3 stated is used for the type according to the inquiry content, and the ultimate facts is obtained from judge's knowledge mapping, The judge's case associated by case marker library searching with the ultimate facts, described sort recommendations module 4 is used for retrieval Obtained judge's case carries out integrated ordered recommendation, and the displaying that described output module 5 is used for result is exported.

Preferably, the method that described inquiry parsing module 2 can calculate similarity using COS distance,D values are bigger, and explanation similarity is higher.

Preferably, the described specific algorithm of sort recommendations module 4 can examine order models using evidence, first to method The true foundation vector F=(f1, f2 ..., fn) of the corresponding dispute of principle is restrained, and ultimate facts is carried out to each class case found Evidences collection, sets up vector P=(p1, p2 ..., pk), common factor is taken to F and P, it is assumed that be (g1, g2 ..., gm), then evidence is obtained Point, score=g1* weights (g1)+g2* weights (g2)+...+gm* weights (gm), weight is the weight of each evidence, it is necessary to pre- First it is ready to.

Preferably, the invention also discloses a kind of above-mentioned search method of judicial class case searching system, specific steps are such as Under：

(1), user passes through the input inquiry content of input module 1；

(2), inquiry parsing module 2 is parsed to the inquiry content of user, obtains the type of the inquiry content；

(3) ultimate facts, is obtained from judge's knowledge mapping by retrieval performing module 3, is examined by case marker storehouse Judge's case that rope is associated with the ultimate facts；

(4), the judge's case obtained by the 4 pairs of retrievals of sort recommendations module carries out integrated ordered；

(5) user, is recommended by output module 5.

Embodiment 1
