Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1, the present application provides a criminal phase prediction method, which can be applied to any electronic device with data processing capability. The method comprises steps S101-S103. Wherein:

s101: obtaining case situation documents of cases to be predicted in the criminal period.

A case document is a file that describes the detailed information of a case. For example, a case may include information on where the criminal case occurred, the time, and the name of the criminal to which the case belongs.

The content of the case will influence the judgment result of the criminal case, and for this reason, the content in the case is used as a reference for predicting the criminal period of the criminal case.

S102: determining a set of key elements contained in the case paper, wherein the set of key elements comprises at least one key element influencing the criminal phase.

As can be known from the introduction of the case, the case contains content information that affects the case criminal period, and the content information may contain a plurality of influencing factors that affect the criminal period from different dimensions, and each influencing factor belongs to a key element in the case.

Such as: the names of crimes, the means of doing cases, the times of occurrence of cases, the places of occurrence of cases, and the like of cases in case documents belong to key factors influencing the criminal period of cases. The method for determining the key elements in the case document may be various, for example, the case document may be searched based on a preset key element library to locate each key element included in the case document, and a key element set of the case document may be obtained.

In one example, determining the set of key elements contained in the case document may also be: and analyzing the key elements in the case document according to the set element matching rules of the plurality of key elements to obtain a key element set contained in the case document. Wherein, the key elements in the key element set belong to a plurality of set key elements.

The element matching rule of the key element is a rule which is constructed based on the characteristics satisfied by the key element and is used for retrieving the key element from the case document. For example, all key elements that may be involved in different case documents are determined by analyzing a plurality of historical case documents, and then, for each key element, the feature or composition rule of each key element is determined according to the description and different expression forms of the key element in different historical case documents, and the like, and the element matching rule of the key element is constructed based on the feature or composition rule of the key element.

For example, for the key element of "drunk driving", considering that the features of drunk driving generally must include two words of wine and driving, the element matching rule of the key element may be a matching rule for locating words or sentences including "wine" and "driving".

For example, considering that a regular expression can be used to retrieve and replace the text conforming to a certain pattern, for each key element, the element matching rule of the key element can be the regular expression of the key element.

In order to take account of the specific forms of the key elements in different case documents, each key element may have one or more element matching rules.

It will be appreciated that the influencing factors of different criminal names differ considerably, and therefore the key elements that need to be followed by different criminal names will also differ. Therefore, the application can set various key elements corresponding to the criminal names respectively aiming at each criminal name, namely each criminal name corresponds to a plurality of key elements, and the types of the key elements corresponding to different criminal names can be different.

Correspondingly, before the key elements of the case are determined, the criminal names of the case can be determined according to the case document. In this case, at least one key element included in the case document is determined based on a plurality of key elements under the name of the criminal act set.

If so, after the criminal name of the case is determined, the key elements contained in the case document of the case are analyzed according to the set element matching rules of the multiple key elements corresponding to the criminal name.

It is understood that the elements affecting criminal phase in case documents may be elements related to law statutes, and may also be elements related to case. Therefore, the types of the elements to which the plurality of key elements set in the present application belong may include: one type or two types of elements of a first type related to case and elements of a second type related to law.

Optionally, in consideration of the fact that the case of the case can more intuitively reflect the specific situation of the case for the case, and the criminal period can be more favorably determined, therefore, the preset multiple key elements in the application at least comprise key elements related to the case.

S103: and predicting the criminal phase of the case by using the trained criminal phase prediction model based on at least one key element contained in the key element set.

The criminal period prediction model is obtained by training a plurality of case condition document samples marked with actual criminal periods and at least one key element. The at least one key element marked on the case scenario document sample refers to a key element extracted from the case scenario document sample, and the way of extracting the key element from the case scenario document sample may be manual extraction, or refer to the aforementioned related introduction of extracting the key element from the case scenario document, and is not described herein again.

The criminal prediction model can be a pre-trained neural network model, a linear regression model or a regression tree model, and the like, and is not limited.

The criminal phase prediction model can analyze and process the key elements in the key element set, and finally determines the criminal phase matched with the key elements in the key element set.

For example, the key elements in the key element set analyzed from the case paper may be converted into vectors, and the vectors of the key elements in the key element set are input into the penalty prediction model, so as to obtain the penalty predicted by the penalty prediction model.

For another example, an element feature may be constructed according to at least one key element included in the key element set, where the element feature characterizes an element category of the key element included in the key element set; and then, inputting the essential features into the trained criminal phase prediction model to obtain the criminal phase of the case predicted by the criminal phase prediction model.

The key element features corresponding to the key element sets can reflect which kinds of key elements are included in the key element sets. For example, the element feature may be a group of element codes, the number of bits of the group of element codes is the same as the number of preset key elements, each bit in the group of element codes represents a key element, and the value of each bit in the element codes represents whether the key element corresponding to the bit exists or not. For example, the value of each bit in the element code is 0 or 1, wherein if the value of a bit is 1, it indicates that the key element represented by the bit exists in the case document; and if the value of the bit is 0, the key element represented by the bit does not exist in the case document.

For ease of understanding, the following are illustrated:

assuming that 10 kinds of key elements, key element 1 to key element 10, respectively, are set, the number of element encoding bits characterizing feature elements may be set to 10 bits, and these 10 bits sequentially characterize key elements 1 to 10.

Then, if the key element set parsed from the case document only includes key elements 1 and 3, when constructing an element code representing element features based on the key element set, a value at a position representing the key element 1 in the element code is 1, a value at a position representing the key element 3 in the element code is 1, values at other positions in the element code are 0, and accordingly, the constructed element code may be: 1,0,1,0,0,0,0,0,0,0.

Correspondingly, the element code is input into a criminal prediction model, and the criminal prediction model can determine which kinds of key elements are contained in the case of the case based on the element code, so that the criminal period of the case is predicted based on the kinds of the key elements contained in the case.

By means of the technical scheme, the criminal period of the case is predicted by utilizing the trained criminal period prediction model based on all key elements contained in the case, so that a basis is provided for a judge to determine the criminal period of the case, the complexity of determining the criminal period of the case is reduced, a large amount of human resources consumed for determining the criminal period by searching similar cases are reduced, the criminal period processing efficiency of the case with the criminal period to be predicted is improved, and the subconscious deviation existing in artificial judgment is avoided.

Because the criminal period is not directly predicted based on the case in the criminal period prediction model based criminal period prediction process, the criminal period is predicted by combining the key elements which influence the criminal period and are contained in the case, and because the key elements contained in the case reflect the cases, the law and other information of the cases more directly and accurately, the technical scheme provided by the application not only reduces the consumption of human resources, but also is beneficial to more accurately predicting the criminal period by combining the key elements contained in the case.

It can be understood that, in order to facilitate understanding of the process of training the criminal prediction model, the criminal prediction model is taken as an example of a trained neural network model. For example, referring to fig. 2, there is shown a schematic diagram of a training process for providing a criminal phase prediction model according to the present application, the process comprising:

s201, obtaining a plurality of historical case documents serving as training samples, wherein the historical case documents are marked with actual criminal periods.

The historical case documents are the case documents of the cases with the determined criminal periods, and therefore the criminal period of the case corresponding to each historical case document is determined.

S202, aiming at each historical case document, determining the criminal name corresponding to the historical case document, and extracting a key element set containing at least one key element from the historical case document according to the set element matching rule of various key elements related to the criminal name.

The at least one key element extracted from the historical case document is the at least one key element which needs to be marked for the historical case document.

Of course, the step S202 is only one way to determine at least one key element in the historical case document as the training sample, and in practical applications, at least one key element in the historical case document may be predetermined in other ways, for example, at least one key element in the historical case document is predetermined and labeled by a worker.

S203, aiming at each historical case document, constructing an element code according to the key element set extracted from the historical case document.

The element code represents the specific category of the key elements contained in the historical case document.

The specific process of encoding the building elements may refer to the related description of the foregoing embodiments, and is not described herein again.

S204, aiming at each historical case document, inputting the element codes corresponding to the historical case document into a neural network model needing to be trained to obtain the predicted criminal period corresponding to the historical case document predicted by the neural network model.

S205, detecting whether the training end condition of the neural network model is reached or not according to the actual criminal period and the predicted criminal period corresponding to each historical case document, and if so, ending the training; if not, adjusting the internal parameters of the neural network model, and returning to the step S204 for training.

The training end condition of the neural network may be: the times of the circular training reach the set times, or the convergence condition of the neural network model is met; the prediction accuracy of the neural network model may also meet the set requirement, and the like, which is not limited.

The adjusting of the internal parameters of the neural network model includes adjusting the weight of each key element in the neural network model, some intrinsic parameters of the neural network model, and the like.

It can be understood that, in practical applications, in order to further ensure the accuracy of predicting the criminal phase by the neural network model, the application may further obtain a plurality of historical case documents for verifying the sample, wherein each historical case document is labeled with the actual criminal phase and at least one key element.

Correspondingly, the trained neural network model can be verified by using a plurality of historical case documents, and if the prediction accuracy of the neural network model is verified to meet the requirement, the trained neural network model can be used as a criminal prediction model. If the prediction accuracy of the neural network model is verified to be not in accordance with the requirement, the training sample can be obtained again and the neural network model can be retrained; or reconstructing various key elements related to different criminal names, or submitting to an expert for rechecking to determine the cause of the problem.

It is understood that the training method of the present embodiment is described by taking the training of the neural network model as the criminal prediction model as an example, but the neural network model is replaced by other machine learning models and is also applicable to the training method.

In the embodiment, the predicted criminal period corresponding to the case is obtained through the criminal period prediction model, so that the basis for case criminal period judgment can be provided for the judge, but the specificity of some cases is considered, and the accurate criminal period of the case cannot be determined only according to the predicted criminal period.

For example, referring to fig. 3, there is shown a schematic flow chart of yet another embodiment of the criminal phase prediction method provided by the present application, the method comprising:

s301: obtaining case situation documents of cases to be predicted in the criminal period.

S302: determining a set of key elements contained in the case paper, wherein the set of key elements comprises at least one key element influencing the criminal phase.

S303: based on at least one key element contained in the key element set, the criminal phase of the case is predicted by using a trained criminal phase prediction model, and the criminal phase prediction model is obtained by training at least one key element contained in a plurality of case condition document samples marked with actual criminal phases.

The above steps can refer to the related descriptions in the previous embodiments, and are not described herein again.

S304: and obtaining the weight of each of the set key elements.

Wherein, the respective weight of the key elements is the weight corresponding to each key element set in the trained criminal stage prediction model.

It can be understood that, after the training of the criminal phase prediction model is completed, when the criminal phase prediction model performs the criminal phase prediction, the weight of each key element applied by the criminal phase prediction model is fixed, and therefore, the respective weights of the various key elements set in the trained criminal phase prediction model can be obtained.

It can be understood that, considering that under different criminal names, the influence degree of the same key element on the criminal names can be different, under the condition of aiming at multiple key elements corresponding to different criminal names, a criminal period prediction model suitable for the criminal names can be trained independently aiming at each criminal name.

Accordingly, after determining the criminal name of the case based on the case' S case document, in the step S303, the predicted criminal period of the case can be determined by using the criminal period prediction model matched with the criminal name based on the key elements extracted from the case document. In this case, the weight of the plurality of kinds of key elements set in step S304 is also the weight of each of the plurality of kinds of key elements related to the criminal name.

The sequence of step S304 and step S303 is not limited to that shown in fig. 3, and the sequence of these two steps may be interchanged or performed simultaneously.

S305: at least one historical case document satisfying the conditions is searched from the document library according to the key elements contained in the key element set of the case document.

The historical case document satisfying the condition is a historical case document having at least one key element identical to the case document.

If the key element set in the case document includes the key element 1, the key element 2, and the key element 3, the history case document is a history case document that satisfies the condition if any one or more of the key element 1, the key element 2, and the key element 3 is also included in the history case document.

In the document library, a plurality of history documents are stored. Wherein, each historical case document corresponds to a key element which is analyzed from the historical case document in advance.

For example, case documents of some more classical cases can be screened out to be used as historical case documents stored in the document library.

Alternatively, the historical case documents in the document library may be a plurality of historical case documents used for training a criminal prediction model. In the process of training the criminal prediction model, the extraction of the key elements corresponding to the historical case document is completed, so that the historical case document and the key elements contained in the historical case document are stored in the document library.

S306, aiming at each historical case document meeting the conditions, determining the similarity between the historical case document and the case document according to the same at least one key element in the historical case document and the respective weight of the same at least one key element.

For example, the similarity between the historical case document and the case document is the weighted sum of the same key elements in the historical case document and the case document.

For example, if the historical case document and the case document have the same key element 1 and key element 3, where the weight of the key element 1 is 0.6 and the weight of the key element 3 is 0.2, the similarity is 1 × 0.6+1 × 0.2 — 0.8.

S307, at least one historical case document with the similarity meeting the requirement is determined from the at least one historical case document meeting the condition.

For example, the similarity conformity requirement may be sorted from high to low, where the sorting belongs to a preset position, for example, the top 5 history cases with higher similarity are determined as the history cases with the similarity conformity requirement.

For another example, the similarity meets the requirement, that is, the similarity exceeds a set threshold, for example, if the similarity exceeds 0.8, the similarity is determined to meet the requirement.

S308: and outputting a key element set, at least one historical case document with the similarity meeting the requirement and the criminal period of the case predicted by a criminal period prediction model.

The historical case information documents with higher similarity to the case information documents of the case are output, so that similar case information documents can be prevented from being manually searched by a judge, a reference basis with another dimension can be provided for the judge to determine the final criminal period of the case by combining the predicted criminal period, and the case information document is more accurately and reliably determined by the judge.

It should be noted that the key element set extracted from the case document outputting the case is only an optional manner, and the purpose of the key element set is to provide search bases for the searched historical case documents for the judge, so that the judge assists in judging whether the searched historical case document is the required case document by combining the key elements in the key element set.

In yet another aspect, the present application also provides a criminal phase prediction device. For example, referring to fig. 4, a criminal phase predicting device of the present application embodiment includes:

By means of the technical scheme, the criminal period of the case is predicted by using the trained criminal period prediction model based on all key elements contained in the case, so that a basis is provided for a judge to determine the criminal period of the case, the complexity of determining the criminal period of the case is reduced, and a large amount of human resources consumed for determining the criminal period by searching similar cases are reduced.
