Design And Implementation Of Information Object Reconstruction System

Information object generally refers to anything that exists in the form of information,can be perceived or imagined,such as people,events,buildings,engineering,houses,etc.The original text information describing information objects exists widely in various information carriers.With the rapid development of the Internet,the content of information becomes more and more complex and the amount of information has approached the mass.At present,the representation of information shows the characteristics of isolated and fragmented.Text descriptions of the same information object are scattered in many webpages,articles or other information carriers,which results in the occurrence,development and outcome of the information object being not displayed intuitively and systematically,and the information of other related information objects and their interrelationship can't be obtained,so the reconstruction of information organization form is of great significance in today's era.Therefore,in order to realize the information reconstruction,this thesis is mainly summarized as follows.(1)An information reconstruction model is proposed.Extracting information based on this kind of data model can make original text structured,and the evolution of information objects over time and their external correlation are preserved.(2)The method of information reconstruction is selected appropriately.Design the data storage model,build the underlying storage environment,and construct the entity information database and entity association database of information objects.(3)A retrieval mechanism of information in entity database is realized,including acquiring the evolution process of entity and external association and other retrieval functions.(4)A scalable,reusable and visualized information reconstruction platform is designed and implemented.It realizes the reconstruction function of the original information sample,the retrieval and editing function of the entity evolution and association in the library,and the visualization service,etc.The innovations of this thesis are as follows.(1)A reconstruction model of information objects is proposed,which includes the characteristics of information objects evolving with time,as well as the correlation and interaction between different but related information objects.(2)A method of information reconstruction combining Language Technology Platform and manual editing is proposed,which reduces the workload of manual reconstruction and improves the efficiency of reconstruction.(3)A set of information reconstruction system based on distributed storage is established,which can provide effective and stable storage,efficient and accurate retrieval and visual display for extracting entity information by using big data framework.
