Research On Design And Application Of Object Evolution And Relevance Model Based On Spatio Temporal Framework

Information object generally refers to anything that exists in the form of information,which is perceivable or imaginable,including concrete and abstract concepts,such as people,events,architecture,engineering,trees,houses,prices,public opinion,etc.With the development and popularization of the Internet and mobile devices,the production of information has grown exponentially.At the same time,the Chinese nation has a long history and possesses a large number of rich information objects.For the retrieval and use of information,it is usually done with the help of network search engines or online information platforms.However,the presentation,storage,and utilization of this information all present problems such as isolation and fragmentation of information.In this thesis,by reconstructing the evolution and relevance model of information objects based on the space-time framework,a Web application platform based on distributed storage is built to realize information collection,integration,reconstruction,and a visual analysis platform.Provide a comprehensive,cross-domain,and cross-temporal visual analysis platform and tools for information query and processing.The main work and innovations of this thesis are as follows(1)Redesigned the object evolution and relevance model,which is composed of object information and relevance information under the framework of time and space.After the original data is subjected to specific processing by this model,the complete spatiotemporal evolution context of the information objects,the relationship between the information objects,and the corresponding detailed introduction content can be obtained.It improves the efficiency of data visualization and makes it more convenient and quicker to further mine the relevance information of information objects.(2)Designed the evolution model of district relevance,abstracted the geographical district in the historical map of China into a district model Formulas and data can be used to describe the relevance evolution of Chinese historical dynasties in detail to further realize the visualization of the historical dynasties and geographical district,to obtain more intuitive information about dynasty changes and territorial expansion.(3)Designed and implemented an object evolution and relevance Web platform based on the spatio-temporal framework,which integrates data storage,organization,extraction,and application.Using big data frameworks,image processing,database storage and other technical means,completed the visualization and cause analysis of the evolution of the geographical district and historical dynasties,the visualization of the evolution of information objects,the functions of mining information object relevance,and the maintenance of basic information.
