Research On Digital Education Resources Crowd-funding Service Model And Application

With the rapid development of education informatization,the construction of education service platforms has also undergone constant changes.The digital education resources available to learners are becoming more and more abundant,and the learning methods of digital education resources have also subverted the traditional learning methods.At the same time,there are also insufficient supply of high-quality educational resources and innovative educational application products in the application of digital educational resources,and the crowdfunding model can break through the time and space restrictions and gather the wisdom and creativity of the public.Effective means.Therefore,the thesis conducts research on the application of digital education resources crowdfunding service model.The thesis mainly focuses on three aspects.First,the application service model of digital education resource crowdfunding is proposed.Based on the theories of wisdom,disciplines,value chain and other theories,this model analyzes the current education resource crowdfunding service ecosystem,from the perspectives of demand initiators,service providers,platform servicers and consumers involved in education field crowdfunding Build a UGBC service model that takes the resource pool as the core,personalized service as the goal,and the government,scientific research institutions,enterprises and users as the parties of interest.Secondly,based on the proposed UGBC service model,the key technologies such as resource aggregation and demand adaptation involved in the digital education resource crowdfunding service model are studied.Based on the analysis of the complex supply and demand relationship generated in the process of crowdfunding services,using user-defined resource tags,combined with TextRank algorithm to extract the metadata information of demand information and service resources,a strategy of demand and service matching based on resource metadata is proposed.At the same time,a network resource collection and classification engine is constructed to realize the classification and aggregation of related resources and provide a technical basis for resource supply and demand matching services.The engine calculates the resource similarity based on the search content,and presents the resources according to the similarity to adapt to the user demand.Finally,an empirical study on the proposed service model and key technologies is carried out.The platform takes basic education,higher education,vocational and continuing education as the service objects.By supporting users to publish resource needs,service providers submit resources and product services,and at the same time crawl various Internet related resource data according to the set content themes It is aggregated and based on the user's search content to achieve the adaptation between platform resources,services and user needs.Application practice has verified that the proposed scheme is feasible and effective.
