"Greetings":Product Design And Planning Of Public Security Information Service APP

With the rapid development of society,the upgrading of public demand structure,and the change of public communication lifestyle by mobile Internet,in recent years,the frequent occurrence of social security events in China,such as traditional security and non-traditional security,has made the public increasingly demand for security information.From 2017 to 2018,the total increase of users of news and information app is close to 230 million,the number of users is increasing,and the demand of users is becoming more and more diversified.But throughout the whole mobile phone security application market,the traditional mobile phone security applications are still in the majority,and few professional security information applications that develop well and target a large number of users.In addition,through user research,it is found that at present,users are more concerned about their own security,more sensitive to risks,and more eager to participate in the production and dissemination of social public events.At present,the development of news information platform dominated by the concept of news aggregation is relatively mature,and the increasing penetration of artificial intelligence has almost completely innovated all aspects of traditional news from birth to distribution to feedback,such as sensor news,robot writing,and the general development and application of VR / AR news,all showing the strong influence of "artificial intelligence + news".In this context,this paper aims to design a kind of application of security informationservice based on the public security news and the core idea of news 2.0 reproduction through the innovative research of "artificial intelligence + news" mode.At present,the development of today's headline based news aggregation information platform has gradually entered a state of weakness.How to deal with the development bottleneck,solve the existing difficulties,and accelerate innovation has attracted more and more attention.And news aggregation and reproduction is expected to become a new breakthrough.Breaking the simple idea of news 1.0 text aggregation and redistribution,and reproducing the aggregated news 2.0 is the main purpose of the design.Therefore,this paper first establishes the product positioning and functional requirements through social background,market and user research;on this basis,it systematically combs the security concept system,builds the four-level security domain dimension table,and provides the basic framework for the construction of security information application database;then,it takes the security index as the product core,mainly based on news text analysis,and based on events The scale analysis and event emotion analysis are the main indicators to build the index;finally,the preliminary design of product form is formed.
