Library information resources belong to big data system. The application of big data technology in library service is the reformation of library management. The nation is strongly supporting the development of information service industry. In the above background, library is also faced with a situation of serving society and enterprise, so as to achieve the benefit maximization. With the rapid development...
As the key point of the ontology research field, concept similarity computation has been widely used in the automatic question-answering systems. This paper firstly analyzes the existing concept similarity computation algorithm which is based on the semantic distance, and then proposes a new computation algorithm formula by modifying and adding some factors which can affect the accuracy of concept...
Web application testing based on user session reduces artificial efforts while designing and generating test cases. It attracts more and more researchers and forms a hot spot of web application testing. Reduction, prioritization, and selection of test cases are widely used for the testing based on user session. In this paper, web application test cases optimization based on clustering is researched,...
The credit rating system for bank customers is based on J2EE technology architecture, is designed from the data sources, customers rating, approval rating and safety management and other aspects. In the paper, we describes the construction of bank customers in the background of credit rating system which is discussed in detail the application of Client/Web server/Application server/Database server...
A network topology method is based on clustering and network tomography technology is described. By using the end-to-end measurement, according to the dissimilarity of measurement data of different end nodes, the logical network topology is speculated. Based on NS2 simulation results, the method has higher accuracy, even in the case of larger link delay.
This paper proposes a database-based E-learning system, which is targeted at the problems existed in the current teaching, combines the network teaching mainstream model and the latest theoretical achievements at home and abroad, as well as uses the current more mature network technology. The system discusses in detail the system requirements and features from the network teaching system design goals,...
At present, China is universally short of professional computer room managers and the modern management of the environment seems especially important, which makes studying and developing a stable, advanced, effective and high performance price ratio environmental monitoring system extremely necessary. Combined with the production practice of hydraulic power plants, this paper proposes a brand new...
In this paper, we propose a gateway system for wireless sensor network based on environmental monitoring. Resource sharing and long-distance accessing are important issues for application of wireless sensor network and environmental monitoring. Itpsilas necessary to connect wireless sensor network to external network which makes the administrator could access data duly and expediently from long-distance...
Traffic accidents cause enormous losses for our country and plenty of national assets drain away every year, and therefore the task of traffic management is weightier than Mount Tai, but the complexity of traffic accident analysis has brought many difficulties to traffic management and decision-making. A three-layer analysis system based on spatial data mining of GIS is proposed in this paper, this...
On the basis of some research work on the educational game sites, we introduce an intelligent system for educational game resource discovery and define a concept of game-metadata structure. It will strive to organize educational games all over the internet and provide a new way of thinking in building game resource database. In this paper, both of the key technologies and the function modules are...
Sequential pattern has important applications in many areas and a large number of data and patterns need efficient and scalable parallel algorithm. In light of the widespread problem in current sequential pattern data mining algorithm and on the basis of researching the data mining algorithm of serial sequential pattern, a data mining algorithm of parallel sequential pattern is presented in this paper...
The characteristics of "poor" information in database and the requirement of "poor" information data mining are analyzed. Based on gray trend relational degree and general system theory, the model of gray trend relational system is investigated. As an application of this model, the gray trend clustering method is presented. Based on the scanty data of some examination papers in...
