The Research Of The Education Application And The Development Of The Flash Retrieval System Based On Lucene

Internet has brought profound influence to our life and makes our life in every field take place great changes. The education field as a great influence on human development is also changing because of the Internet. In the field of education, both teaching tools and teaching will be affected by the new technology, and then changing. The multimedia teaching dominated by computer-aided has become an important part of information-based teaching, which provides a great convenience for the contemporary teacher's effective teaching and students' effective learning. Nevertheless the multimedia teaching requires a lot of instructional resources, and the Flash education resources is one of the most important ones, but searching the Flash education resources accurately on the net is relatively difficult, so how to obtain the Flash education resources accurately become a difficult problem in the current education.In modern computer network the tool to get a lot of information resources is a retrieval system, there are a lot of retrieval systems retrieving text, images, sound, animation and video retrieval system, most of which are retrieved by matching names and keywords. The information retrieved by this method are general and fuzzy, fortunately the flash retrieval system based on the contents, to a great extent, solves the problem of retrieving flash inaccurately, but there are very few research and development of the flash retrieval system based on the contents, and this prevents the flash education resources from playing an important role in the teaching, so we need to make an fast, accurate and full flash retrieval system based on content. Lucene as a good search engine technology, firstly, uses inverted index technology to solve the problem of the low access efficiency for the system; secondly, it uses the advanced segmentation word technology to provide accurate data analysis for the retrieval; finally, it uses reasonable document score technology to sort the results to return to the more reasonable query results for users. So, in order to achieve retrieving flash efficiently, this study uses lucene retrieval technology to develop the flash retrieval system based on the contents.On the basis of understanding lucene fully, this study use.net version of lucene to develop the flash retrieval system based on content. The system includes the index module, the analysis module and the retrieve module, and according to the actual situation the system chooses the optimal solution. The system provides users with a basic retrieval page, an advanced retrieval page and a displaying the query results page, which are all used as the user interface. This system provides system administrators with a generating index pages for the backstage to process and analysis data, thereby generating an index to provide the front desk with index database. Flash are the most important resources, of course, and there are more than five hundred thousands flash resources downloaded from the network, which are stored in the database after a professional analysis to Lucene for processing.The development of the retrieval system is completed, then the study will be able to analysize the educational characteristics of the flash resources more comprehensivly. At present, the educational flash resources have become an important educating and teaching resources. As the education resources, it firstly has discipline and learning characteristics, the students of different disciplines and different study periods demand different education resources. According to analyzing and summarizing, each type of Flash have their unique properties, such as teaching methods, question teaching type, logical structure and artistic features and so on. But these unique properties of the educational flash resources lack unified classification research, also lacking the cognitive research, and this is bound to reduce the use efficiency and application efficiency of flash instructional resources. Here there will be a lot of artificial analysis of educational flash resources from the teaching way, the problem teachingtypes, logical structure and artistic characteristics. Summing up the flash characteristics of the different grade and different subjects makes the educational Flash resources to promote the teaching and learning better. Finally,the author analyses the application of the system in education, and apply the system in the curriculum of Flash animation, and analyzing its educational application from three aspects, such as the education resource, teaching and self-study application re, and summarize the application effect and improvement suggestions.
