specific Embodiment approach 1
[0028] An auxiliary sentencing method for theft crime based on deep learning, such as figure 1 shown, including the following steps:
[0029] Step a. According to the provisions of the criminal law and the sentencing regulations on the crime of theft, combined with the published first-instance judgment of the crime of theft, define the 11-dimensional characteristics of the theft case in terms of the value of the stolen items, the information of the criminal subject, the description of the crime facts, and the judgment result , the 11-dimensional features include the value of the stolen items, whether the defendant is a minor, whether the defendant is a disabled person, whether there is burglary, whether there is a murder weapon, whether there is pickpocketing, and whether there are other serious circumstances , Whether the defendant is a repeat offender, whether there is a circumstance of refund, whether there is a circumstance of surrender, and whether the sentence is sentenc...

[0044] On the basis of the specific implementation mode 1, another implementation-based auxiliary sentencing method for the crime of theft based on deep learning includes:
[0045] Step a. After sorting out the provisions on the specific application of penalties in Chapter 4 of Part I of the "Criminal Law of the People's Republic of China" and Article 264 of Chapter 5 of Part II on the sentencing provisions of the crime of theft, combined with The analysis of the published first-instance verdicts on theft crimes, including the value of the stolen items, information on the subject of the crime, the description of the criminal facts, and the verdict, summarizes the following 11-dimensional features of the theft case, including the value of the stolen items and whether the defendant is a minor whether the accused is a disabled person, whether there is a case of burglary, whether there is a case of carrying a murder weapon, whether there is a case of pickpocketing, whether there ar...

Abstract
The invention discloses a deep learning-based larceny auxiliary sentencing method, and belongs to the field of computers. The method mainly aims to solve the problem that the case semantic representation and the criminal period accurate prediction of a specific criminal name cannot be realized under the condition of less manual annotation, and comprises the following steps of defining the 11-dimensional features for formally describing a theft case from the perspectives of stolen article value, crime subject information, crime fact description and judgment result according to the criminal lawprovisions and sentences provisions about the theft and in combination with a disclosed theft first-review decision-making document; preprocessing the text of the judgment document; integrating into acorpus set, and training the word vectors; extracting the features except the values of the stolen articles and the criminal periods, and constructing a feature generator for each dimension of features by using a recurrent neural network so as to extract the feature values; using the linear regression and a multi-layer neural network model as the predictors, inputting the case feature vectors, and outputting the criminal period prediction results, so that the deep semantic understanding of the case can be realized and a clear criminal period prediction value can be given under the condition of less dependence on the manual annotation.
Description
technical field [0001] The invention belongs to the field of computers, and in particular relates to an auxiliary sentencing method for the crime of theft based on deep learning. Background technique [0002] The amount of data in the judicial field has grown rapidly over the past few years. These data involve judicial documents, laws and regulations, and judicial interpretations of various legal cases. Legal professionals such as judges, lawyers, and prosecutors not only have to deal with a large number of cases, but also need to consult a large number of case-related documents for reference and analysis. This places an increasing burden on legal professionals and can lead to reduced productivity and an increased risk of judicial errors. In order to better defend judicial justice and protect public safety, the auxiliary sentencing method based on artificial intelligence and data mining technology needs to be applied to judicial practice. [0003] The task of auxiliary se...
