This paper states the necessity of establishing the economic evaluation system for safety resources in traffic enterprises systematically. The author gives the connotations of the proposed new economic evaluation system in traffic enterprises. The proposed evaluation system for safety resources can be used in all units with possible traffic accidents for estimating and reflecting the economic effectiveness...
The advance of image capture device and the popularity of the Internet have made the World Wide Web the biggest and most diverse repository of images. How to retrieve images fast and accurately from the WWW has become an urgent problem to be solved. Although many commercial Web image search engine has come forth, the precision is not satisfying for the reason that the text in the pages which they...
When Blog comes to the world, how to use Blog in education and instructions well has been one of the interesting studies among academic field increasingly. In this paper, by reading great material and communicating with the teachers in Rizhao open-up areal, it discussed the applications of Blog in education and teaching from sharing resources and communication of teachers, students and studentspsila...
Virtual learning community give students more free and open environment for studying on the Internet. This research is based on constructive learning theory and virtual learning community, from design and speciality of virtual learning community, and the ways of browsing.
Grid technology is a research hotspot nowadays. To apply grid technology to education resources management will maximize integration of existing education resources. Education resources can be managed effectively by using distributional management thought, which can change current status of the disorder about education resources management. In this paper, resource classification standard in LOM is...
This paper proposes a novel algorithm to extract the informative blocks from web pages and filter the advertisement which has noting to do with the subject when people browse the Web page. In this pager, we use HTML parser to construct DOM tree and apply corresponding rules to construct a new tree (CST) which can easily help us to separate the ldquoprimary content blocksrdquo from the other blocks...
This paper puts forward the concept of WWW information domain analysis to promote the efficiency to acquire WWW information and make good use of information through Intranet. It is to achieve WWW Information Subject(WIS) that is seemed as the foundation of the research. So this paper explores the management mechanism of WIS, and finally a simulation example is given to validate the thought in the...
Duplicated web pages responded by search engines not only waste valuable storage, but also aggravate burdens of userspsila browse. Web page de-duplication can effectively improve the information retrieval. This paper proposes pretreatment of web pages to improve the effectiveness and efficiency of web page de-duplication based on feature code according to the principle of data clearing. This paper...
In recent years, several worms attacked the Internet and caused serious global damage. We consider that if we can detect the worm in its early spreading stage and perform the access control policy on the related routers immediately, the disaster may be alleviated or even avoided. E-Alarm makes use of network topology information, analyzes anomaly alarms using clustering method, and gives access control...
With the development and widely used of Internet and information technology, the Web has become one of the most important means to obtain information for people. According to the Web document classification and the theory of artificial neural network, a Web classification mining method based on wavelet neural network is presented in this paper. Moreover, we adopt a algorithm of reduce the number of...
The aims system of message-driven model changes the way of data exchange based on Web Services from pull passively to push actively. The message-driven publish/subscribe gives recommended find Web Services model, it changes the way users find Web Services. The key technologies of the platform model are discussed Last verifies the feasibility of the design model combined with concrete examples. The...
Along with the development of internet, a lot of new data appears in the web every day. To construct a retrieval model to adapt the new data quickly and to retrieval the new documents accurately is becoming an important research topic. In this paper, we put forward a new retrieval model by incorporating the theory of transfer learning with Markov Network. Firstly, compare term spaces network of old...
Video annotation is very important for video management, such as video retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel video annotation framework based on the video object is presented, named object-based...
In this paper, we propose a novel framework of large-scale and real-time image annotation system. The large-scale image set is constructed based on current Web image search engines and re-ranking algorithm. Various global and local features are employed for representing images with parallel extraction mechanism for the real-time requirements. At training stage, the distance between class centers in...
The concept of Shannon information entropy is introduced to area of e-commerce. Sorting of significance of attributes in database based on entropy is proposed to discover information value on e-commerce information analysis. The information entropy is also applied to integration of e-commerce to measure betimes, continuity, objectivity and comprehensiveness.
This paper proposes a cooperation mechanism among seller agents and builds a model based on multi-agent system. In the model, a manger agent has been set to watch activities of other agents. It will encourage the cooperative sellers and punish the non-cooperative seller agents by adjust the sellerpsilas reputation in the repository. With this mechanism, a seller would complete the trade with the buyer...
According to the requirement of providing personalized service to users in e-learning systems and the problem of presenting the semantic relationships of users' interests in traditional user models, this paper discusses the representation and the construction of a personalized user model which represents individual userpsilas interests by semantic mining from userpsilas resource searching process...
Put forward a new information retrieval method based on the query specificity after analyzing the existing problems of information retrieval system. The experiments show that the system has better query performance. Avoid the similarity documents in the first few pages effectively, when the system return a larger set of query documents.
