Design And Implementation Of Intelligent Question Bank System For Fragment Question

With the rapid development of big data and cloud computing and the further application of artificial intelligence, computer-assisted education has become an important research topic in education. At the same time, the tests in online examination system were more fragmented than before in the context of large data services, which posed serious challenges to the organization and management of the examination questions in on-line examination system. There was a weak correlation or no correlation between the fragmented tests. It made users cannot make full use of the existing tests to organize examination and conduct practice. If you were not able to fully tap the relationship between tests, the using efficiency of the tests would be greatly reduced. In order to help the users to use tests more fully and to mine the related information of tests, this paper mainly designed and realized a set of intelligent examination system for fragment test.This article analyzed the related literature in recent years of online education and online examination system, combined with the actual situation of teaching, put forward a kind of intelligent test database system for fragmentation test.The following is the concrete scheme of intelligent test database system:(1) firstly, through the analysis of the knowledge points and questions, the author constructed a fragmentation test organization model; through the design of the model, the author summarized the strategy of the test organization by combining with the knowledge; through sorting out knowledge points of the system and relationships between tests effectively, the intelligent test system would be better organization and management. (2) secondly, on the retrieval for tests, knowledge and other resources, by using elastic search engine adding weight to the index key differently, the author improved the efficiency of the resource retrieval tests; (3) finally, for the design of intelligent database system, the author adopted the micro-service design architecture which was very popular recently and was adopted between the loosely coupled system, it could provide a good solution for the database system on switching multi-data.sources, pooling database, separating read and write.Through the above design and implementation of intellectual test database system, after the system deployed and ran eight months, through analyzing the server, the system could quickly respond to users’requests; through retrieving and analyzing 40,000 tests, the relationships between different tests could be figured out effectively. Experimental verification showed that intellectual test database system oriented to fragmentation test could provide effective services for the organization and management of tests and provide a good support for intelligent test paper.
