Object-oriented classification (OOC) has shown many significant advantages over other methods for classification of urban or forest ecosystems. However, it remains unclear if this technology could exhibit these advantages on mapping monospecific plant stands in herbaceous plant dominated ecosystems (e.g. saltmarshes). In this study, we compared the effectiveness of OOC and pixel-based classification...
This paper presents a framework of a platform for interactive mathematics education. This platform mainly integrates three technologies: topic-based search engine, Deep Web information integration and Wiki. Mathematics information is gathered by topic robot with mathematics classifier which based on SVM classification algorithm. Form filling technology, based on the web page structure, is used in...
Wiki is the typical application of social computing. In this paper, the author first analyzed the traditional Wiki; then in order to resolve the Wiki's problem of poor knowledge structure and reuse, the author introduced an idea which stated that the Wiki can be designed to be a tool to present the knowledge Ontology of itself by using the semantic web technology; then on the basis of it, the author...
The Web contains a lot of information about personal social relations, how to efficiently and accurately extract social relations of Web persons is the focus of this study. According to the Web information, this paper classifies and defines the social relations, and selects eight kinds of personal relations to extract their feature words based on a Tongyici Cilin, and then uses the limited nature...
This paper has designed and implemented a deep search engine oriented to the domain of popular science using subject search technique and the deep Web integration technique. It has introduced the system architecture, the subject information gathering strategy as well as the key technologies it used, and our Web page classifier has high accuracy with experimental verification. In the end, system retrieval...
This paper presents a framework of a platform of popular science education based on social computing, involving Wiki technique and subject search technique. On this platform, users can use the popular science Wiki to add, edit and comment on popular science information, create their own popular science resources and communicate with each other widely. Meanwhile, their self-learning abilities will...
Based on the method of information hiding, a novel algorithm for security speech communication is designed in this paper,and the synchronization code can be used to search the embedded location. Firstly, the DWT is performed on each segment of the original carrier audio; Secondly, the embedding bits are constructed by the synchronization code and secret audio ,and the secret bits are formed by chaotic...
This article refers to the application of Web mining in the remote education, and on the base of Web mining puts forward the concept which designs the management system of Remote Education based on Constructivism, and in order to improve Distance Learning Systems also discusses how to optimize the Constructivism learning environment in this system by Web mining techniques, such as clustering analysis,...
