Research Of Exhibition Assessment Based On Network Data Analysis

For more than a hundred years,modern exhibition made great achievement and generated lots of profit,since from Sample Exhibition in Leipzig,Germany,1894.It is precisely because the exhibition industry can bring huge economic benefits,the exhibition assessment has become a hot issue.However,the approaches of assessment are still only assessing the exhibition’s offline index effect.Although the system is relatively mature method and index,but in the era of Internet,a great amount of information about exhibition explored in Internet,which makes data from networks also be an indispensible index of exhibition assessment.Thus it is necessary to propose and implement the method of exhibition assessment based on network data analysis.Analyzing and doing research on exhibition assessment industry history,current approaches of exhibition assessment and Internet information,this article combined the characteristic of network data and exhibition data,and proposed a new approach of exhibition assessment based on network data analysis and converged the criteria of network data into the current assessment system,provided the exhibitors,audience and exhibition organizers with a more objective assessment approach.This article designed and implemented an exhibition assessment management platform with B/S architecture,Scrapy,Django,MySQL,PhantomJS+Selenium and many other techniques.Data acquisition module implements access to the Internet search engine data acquisition and professional exhibition site data,and solve the problem of dynamic data acquisition.Data processing module implements web unstructured data transform to structured data,and extract basic indicators: time,attribution,IP / PV,etc.Data storage module implements efficient operation of the database,and design KV database to improve the efficiency of the database.Data analysis module implements the extracted information of timeliness,coverage time and space coverage,information dissemination,etc.Data visualization module implements visualize and interact.Management System module implements clearly defined and easy to operate interface.After the stages of design,coding and debugging,functionality and performance of the system has been basically meet the design requirements,functional modules have been successfully achieved,and laid a good foundation for the exhibition assessment method based on network data analysis.
