Design And Implementation Of A Class Case Model Based On Hadoop

The unified business application system of the national procuratorates was officially launched in 2014.Since its operation for four years,the database has recorded more than 30 million pieces of data and more than 40 million pieces of documents.Combined with the ongoing e-procurement project,a large amount of business data will flow into the data center of the provincial procuratorate.How to build a data analysis platform,give full play to the effectiveness of various business data,let the data no longer lie in the database "sleep",and make it become one of the bases for improving the prosecutor's investigation level and assisting in decision-making analysis.It is constantly excavating.The procuratorial organs unified the potential of the business application system to make it play an important role in an important direction.With the development of technology,massive data analysis technology based on cloud computing has emerged and has shown great vitality.Hadoop2 massive data analysis technology has brought data processing technology to a more advanced stage.It can not only store and query past structured data.Through massive data analysis,valuable knowledge,rules,or higher-level information can be extracted from the relevant data sets of the database.In this way,people's application of data can be improved from low-level query operations.To provide model data support for more procuratorial work.This topic is for the research of the Procuratorate industry big data application base-similar case model.It is mainly to use Hadoop2 technology to achieve the classification of similar cases in the Procuratorate,and to provide support for the prosecutors' case handling.Based on the Class Case Model,procuratorates at all levels can improve the quality of prosecution work in many aspects.Including case supervision,case trials,case studies,case supervision and other procuratorial work.Through the following steps: data preparation processing,case feature extraction,building a Case Model,class service implementation.Final realization of the Class Case Model.Provide basic data support and services for follow-up intelligence assisted case handling and similar case push.Make inspection data produce greater value and significance.
