The Design And Implementation Of Publicity Data Query System Based On Enterprise Profile

With the rapid development of market economy,aiming at the ubiquitous commercial risk,companies need to know the partners operating conditions,corporate assets,business scale as a reference for the cooperation when they seek partners in the selection of projects.But they need to query each publicity system data to obtain enterprise information,no enterprise information integration system to facilitate their inquiries.To solve the above problems,a publicity data query system based on enterprise portrait is proposed.The data of the publicity system for analyzing and processing is colected,and brought to the relevant enterprise information file.As an important guarantee to avoid infringement of consumer rights and commercial fraud,also as an important basis for government policy support and bank credit.It is also as an important reference for mass consumption,trade,employment and other decisions.It has a great role in promoting the development of China enterprise credit industry.Firstly,based on the research of related technologies,the data deduplication and hash algorithms are summarized.Secondly,the core technology of enterprise publicity data query system is focused on.Publicity data based on web crawler is collected.A general ETL data processing framework is designed.A massive data update scheme based on hash algorithm is given to solve the problem of frequent updating and time-consuming.Then,the improved vector space model based on relevance ranking algorithm is applied to the Solr search framework for improving the user retrieval satisfaction of search results.Finally,the system is designed and implemented,including architecture design,database design,core modules design,and so on.The real enterprise publicity data is taken as the test data to verify the validity of the data update scheme and the improved algorithm.The publicity data query system based on enterprise profile is designed and implemented in this paper.The specific application background and needs are considered.The suitable architecture and technology framework are chosen.The reasonable logic program and the physical model are designed.At last,convenient enterprise information services are provided.The system can help the users to query multi-dimensional enterprise publicity information,and retrieve the information efficiently.
