Design And Implementation Of Public Opinion Monitoring System Based On Micro-blog Big Data

With the increasing enthusiasm of the public on the Internet,the terrorist threats information to civil aviation security show an upward trend.As the most influential way of communication in the network,micro-blog has become an important way to publish the threat information of civil aviation security.Real-time control of the dynamics micro-blog is necessary to civil aviation security.However,opinion is rapidly disseminated in micro-blog through thousands of users.We are unable to filter and deal with such a huge amount of micro-blog information.In micro-blog big data environment,the design and implementation of micro-blog public opinion monitoring system applied to civil aviation security is given in this paper.The research object is information of micro-blog,especially which contains terrorist threat.We monitor these data constantly.Once any threat message appearing,we will find out the publisher,at the same time,dig his personal information,historical speech,and friends of his blog.These information will be analyzed and provided to the relevant departments of civil aviation immediately.First of all,an overview of the topic web crawler and micro-blog sentiment analysis technology used in micro-blog public opinion monitoring system are introduced in the paper.Other technologies,such as scrapy crawler framework,sentiment analysis technology,software application framework SpringMVC+Mybatis,search engine Solr and Spring-Task task scheduler are also introduced,so as to lay the foundation and realization of system design.Secondly,combined with the needs of Civil Aviation Security Department of micro-blog public opinion monitoring system,the design of the overall system architecture,technical architecture and function is given in this paper.The system function is divided into four parts: micro-blog information collection,analysis,exchange and system management.Detailed analysis and design of each module are carried out.Finally,functions of each module are implemented,and each function of the system is introduced.The test of system function from the core functions,simulation,actual operation is given,and the operation results shows that the system design meet the requirements of civil aviation security department for micro-blog public opinion monitoring.
