Application Research On Personalized Information Aggregation Technologies Of General Browser

With the development of information technology and network technology, theG/S model is also rich, and develop into a new spatial network service model that isgeneral browser/servers cloud now，its application has gradually became industrialand popular. These applications brought a lot of industrial data and personalcharacteristic demand information. The data is often heterogeneous, mass, dynamicand changeable, and has significant spatial and temporal characteristics. The needs ofthe useralso were complex, changeable in real time. How to manage these vastamounts of heterogeneous industrial data as well as how to meet personal demandsfor the application, solve the information overload and information lost, and thenprovide on-demand personalized information services to the users in generalbrowser.It’s an important issue that personalized information aggregationneed to bestudieddeeply.On the basis of the research of personalized information service technology,propose a convergence model of personalized information based on user interest，andthen there is an exploratory study on personalized information aggregation modelbased on G/S model which combined with the characteristics of the spatialinformation services cloud in the architecture, data and the ways of providing servicesetc.Based onthe Eclipse RCP framework, make some extensional developments ofgeneral browser, andthen realize the extensionalcomponent-based applications forpersonalized information aggregation model in general browser.Itreflectsprogressiveness, novelty and practicality.In this thesis, the research workconducted as follows:(1) Research personalized information aggregation model of generalbrowser: usepersonalized recommendation algorithm in informationservices and personal interestmodel as a research object, research the building, updating, and informationrecommended methods of personal interest model, combined withG/S model whichinclude the characteristics of the spatial information services cloud in the architecture,data and the ways of providing services etc,and then there is an exploratory study onpersonalized information aggregation model in general browser. (2)Research the extensionalcomponent-based applications for personalizedinformation aggregation model in general browser: on the basis of geographicinformation browser, make some extensional development of general browser basedon the Eclipse RCP framework, and then realize the extensionalcomponent-basedapplications for personalized information aggregation model in general browser.Through the above research work, the main obtained research results are:(1)Established a convergence model of personalized information based onpersonal interest model.On the basis of the study of being widely used personalized informationrecommendation and combined with G/S model and XXML/HGML data resourceexchange labeling standards, this article established a convergence model ofpersonalized information based on personal interest model. Expressedpersonalinterest modelbased on vector space model, used different technology to buildshort-term personal interest model and long-term personal interest model, selected adifferent way to update short-term personal interest model and long-term personalinterest model by different interest drift policy, optimized personalized informationrecommendation algorithm, and then provided users with on-demand personalizedservice, exploredthe personalized information aggregation mode of the G/S model.(2)Establishedthe extensional component-based applications for personalizedinformation aggregation model in general browser.On the basis of the study of the general browser, combined withthe underlyingdevelopment library modules, made some extensional development for industrialapplication, enriched the overall architecture of the general browser.On the basis of the works that have done, there are two aspects of innovation ofthe paper. As follows:(1)Put forward an aggregation model of personalized information based onpersonal interest model.On the basis of study of personalized recommender technology, the papercombined withthe characteristics of G/S model architecture, data structures, the waysof providing services and industrial application,used the building and updatingtechnology of personal interest model, designed a personalized informationaggregation model.(2)Put forward a solution forthe extensional component-based applications forpersonalized information aggregation model in general browser.On the basis of in-depth analysis of the general browser, used base developmentlibrary of general browser, extended industrial applications from the popular,industrial and personalized application, realized the extensional component-basedapplications for personalized information aggregation model in general browser.
