The Design And Implementation Of An Intelligent Cognitive System Based On MVC Architecture

Cognitive computing,as a new computing model,makes use of the technological achievements in the fields of information analysis,natural language processing and machine learning,and innovates to enable computer systems to analyze data and make correct judgments and decisions like human brains through learning and thinking.Its application effectively breaks through the traditional technological means and has great practical value and significance.Based on the analysis of the research status and development of the application technology of intelligent cognitive system at home and abroad,and on the basis of people's demand for consultation in the field of government policy and service,this paper designs and completes the solution of building the framework of intelligent cognitive system.The system interacts with natural language,through data sources,data aggregation,knowledge base,knowledge retrieval,dialogue and interaction,and voice.Access,edge computing and other technologies are integrated to complete the overall architecture design of intelligent cognitive system.The system uses Java,service-oriented architecture SOA and B/S mode.Based on MVC three-tier structure,the system uses Web Service,AJAX,data access object,O.RMAPPING technology,JSON,XML and other technologies to complete the system knowledge base,semantic recognition,intelligent dialogue and so on.The design and implementation of the core module of the system,through spatial database and spatial analysis cloud services,complete the basic information keyword and classification query search,including dialogue control,context management and knowledge base search,knowledge base,text classification,semantic role annotation,context semantic understanding,slot information supplement,answer extraction and generation and other functions.At the end of the paper,the system is tested in the professional field,and the intelligent cognitive system based on MVC architecture is validated.The results show that the system meets the design requirements and objectives.
