Interaction between the student and the instructor is important for the student to gain knowledge. Also, one of the major tasks on the instructor in e-learning is to reply student e-mails and posted messages. Students usually raise their questions by these two methods in an e-learning environment. In this paper, we introduce a semantic-based automated(More)
In this paper, we offers a HIP-based vertical handover scheme under MIH architecture in heterogeneous wireless network. Many diversity wireless access technologies are offering in Next Generation Wireless Networks (NGWN). In NGWN, the integration of wireless access network will be accomplished by seamless handover which contains many challenges i.e. service(More)
The standing long jump is a standard test for primary school students. It can be used to evaluate the development of basic sports skills of a child. This paper presents a system that can automatically detect the motion during a standing long jump from a video sequence. The silhouette of the jumper in the film is segmented from the background first for all(More)
This paper presents a method of word sense disambiguation that assigns a target word the sense that is most related to the senses of its neighbor words. We explore the use of measures of relatedness between word senses based on a novel hybrid approach. First, we investigate how to "literally" and "regularly" express a ''concept". We apply set algebra to(More)
The construction of metadata which annotates the documents is one of the major tasks for making data understandable to the machine on the Semantic Web. Most of the exiting Semantic Web authoring tools allow user with limited knowledge Semantic Web technologies such as RDF, OWL to markup documents with semantics. These tools help to create the semantic(More)

Along with the rapid development of Internet technologies, the instant messaging has become nowadays an important medium for a huge number of people to communicate with friends, family, and even colleagues while working. People who come from different corner of the world speak different native-languages. Even if the instant messaging technology is now so(More)
Knowledge is a product out of interaction. In online community learning, learners are encouraged to ask questions and discuss answers with each others. The value of participation and sharing during learning is emphasized. However, interactions between learners and between learner and instructor address a problem the instructor cannot be online all the time(More)
Most of the existing textual information retrieval approaches depend on a lexical match between words in user's requests and words in target objects. Typically only objects that contain one or more common words with those in the user's query are returned as relevant. This lexical based retrieval model is far from ideal. In this research an approach to(More)
With the rapid development of E-learning, collaborative learning is an important kind of group learning mode. It emphasizes the communication and information sharing among group members. Current collaborative learning systems haven’t reached a high interaction degree between the students and the instructor to gain knowledge. In order to solve this(More)
