Media Database Construction Concept,Process And Norms

Big data technology provides new ideas for the transformation and development of media industry in the era of big data.The media industry,which is engaged in information production and communication,has massive data resources.The construction of media database is an effective way to give full play to its data advantages,which will be conducive to the innovation of media business and the expansion of media industry chain.As one of the sub-databases of media database,emergency database plays an important role in the field of media practice.The introduction part expounds the background and practical needs of The Times when media urgently need to build a database,the theoretical and practical significance of media database construction,as well as the research status of media database construction,the research status of humanities and social science database construction and the research status of emergency database construction.The first chapter studies the era of big data media,the necessity and feasibility of construction of database,technological progress bring communication form and content of the change,the media must arm themselves with technology to complete the transformation and upgrade of the industry,the construction of the media database will reshape the era of big data media industry core competitiveness,optimizing the integration of media resources,as well as innovation service mode of media industry.In the era of big data,massive information is presented in the form of data,big data technologies such as data mining are gradually mature,and media practitioners are developing towards big data talents,all of which lay a foundation for the construction and application of media database.The second chapter designs the process of media database construction based on man-machine collaboration.Taking the emergency database as an example,it mainly includes two parts:data collection and data processing.Among them,the data acquisition process includes the development of acquisition standards,design of acquisition tools,clear data storage mode;The process of data processing includes data cleaning,data conversion and data checking.In addition,it also clarified the scientific norms that should be followed in every process and link.The third chapter studies the concept and main methods of data mining.The data mining technology used in the construction of emergency database mainly includes statistical analysis,correlation analysis and machine learning.By analyzing the practical application examples of data mining technology in natural disaster database and accident disaster database,this paper further expounds the important value of data mining technology in the construction of media database.The fourth chapter deeply discusses the application and value of media database,which innovates the idea and method of news business and makes the news report transform from "descriptive report" to "data report" and from "post report" to "process report".Media database is an important basis for realizing the function of media prediction and an effective way for media to provide consulting services for other industries and expand its own industrial chain.Finally,media database promotes media's participation in public service and innovates the way of social governance in the era of big data.The fifth chapter is the summary and prospect of the full text,pointing out the three deficiencies in the current media database construction process,that is,incomplete data samples,data accuracy is insufficient,the practice degree is not deep.In the era of big data,attaching importance to the construction and application of media database will bring profound changes to media in terms of content production and industrial chain structure.
