Research On Silverlight-based Learning Resources Retrievability

As the saying goes AECT definition of educational, technology and learning resources is one of the eternal theme of educational technology research. Educational resources must be presented through the appropriate media technology, where 2D graphics animation is one of the most basic media, has a pivotal role in the educational media, typically as the prevailing and popular for many years Flash, and recently Microsoft introduced Silverlight which is based on international standards XML. This paper will be probing in Silverlight-based learning resources retrievability, and also make a compare with flash,then find a different 2D animation development technology advantages of learning resources retrievability, thereby expect to promote the development of Silverlight-based learning,which is the new trend of the future learning resources construction. And to promote in the current massive learning resources situation and environment, the sustainable development of learning resources retrievability. Maximize promote shared as well as reuse learning resource.As the first endervor, I did a study on the 2D animation technology choice of learning resources at the exploitation stage. In the exploitation of 2D animation learning resources, Flash is the classic techniques, while Silverlight is a nascent technology. This paper investigated the Silverlight and Flash, including the animation development platform, the data transmission efficiency, resource sharing deduplication, interactive achieve four dimensions to compare them to explore the pros and cons of each technology under different scenarios, the resoult shows that, for the learning resources retrieval problem, the choice of Silverlight technology as a learning resource development dimensional animation technology, can be retrieved effeiciency, more in line with the trend for future sustainable development.And then research the classification of learning resources. In according with standards of learning Resource organizations or national at home and abroad to explore suitable method for 2D graphics animation classification, for achieve binding of Silverlight files and learning resources, to lay the foundation for subsequent retrieval.Finally, through the analysis of relevant technology, choose the appropriate search technology retrieval system algorithms and theoretical foundation, and develop the appropriate retrieval system modules, the system is capable of binding to expect large MOOC platform, developed into a useful learning resource retrieval module. For the Silverlight internal resources for learning resources to retrieve the text, we use the information retrieval and semantic search technology to achieve retrieval software. Combined with the advantages and disadvantages of information retrieval model Boolean model, vector space model, structured text retrieval models and statistical language model and semantic retrieval model, ultimately use Visal Studio development tools-based learning resources retrieval platform for Silverlight.
