We propose a novel T-commerce model based on semantic interaction, as the TV broadcasting environment is moving to interactive digital TV such as IPTV, Hybrid TV, and Smart TV. The purpose of our work is to design and implement the system of our new T-commerce model. Thus, our system applies spatial relation rules and ontology for object recognition if a viewer is interested in one on the screen of...
As a model for knowledge description and formalization, ontologies are widely used to represent user profiles in personalized web information gathering. However, when representing user profiles, many models have utilized only knowledge from either a global knowledge base or a user local information. In this paper, a personalized ontology model is proposed for knowledge representation and reasoning...
Extensible Personal Learning Environments (PLEs) and Cloud Learning Environments (CLEs) that facilitate the lone or collaborative study of user-chosen blends of content and courses from heterogeneous sources, including Open Educational Resources (OERs), are gradually gaining ground in the landscape of distance learning. In this paper, we examine the use of ontologies for modelling and supporting learner...
Teaching has always been a face to face interaction and hence requires physical presence of both teacher and the student. Teleteaching has been a revolution since it introduces teaching to geographic independence hence is a distributed system. Teleteaching as in any collaborative environment is very difficult to design. Before any implementation we need to model the system, here we have used ontology...
User knowledge structure modeling helps us to understand user's information requirements much better than ever. This paper introduces an Ontology-based user knowledge structure model building and maintaining technology, the model established in this research provide better experiences to users when they request information services, and promote the quality of information services. Based on the model,...
Query interface is used to formulate queries to receive needed data from web databases in deep web. In order to access domain-specific databases, the most important step is to construct an integration interface that allows uniform access to disparate relevant sources. Therefore, this paper proposes a novel method of integrating query interfaces based on ontology in deep web. Firstly, make full use...
In deep web, a significant amount of information can only be accessed through query interface of a back-end database, however, general search engine can not interact with the query interface, resulting in the myriad hidden and unvisible information can not be accessed. Therefore, this paper proposes a novel method of filling forms of deep web entries by importing ontology technique. Firstly, construct...
Information fusion is an interdisciplinary research field aiming to combine and merge the information or data from different information sources. The output of information fusion system is a global schema through which users can get information or data from different dispersed sources. To generate a deep Web information fusion system is facing many challenges, because the nature of Web is different...
In view of the low accuracy and the lack of intelligence and individuation in existing information retrieval system, the capacity of resources semantics description of ontology and multi-agents characteristic of intelligence and individuation were used in this paper. Model of multi-agent information retrieval system based semantic Web was proposed in virtue of the combination of semantic Web and MAS...
It has become common to search necessary services and contents using the Internet, but it is difficult to find exactly what one is looking for through keywords as each service is described in just too many ways. We developed "laddering" search service system that matches the needs of the users with the search targets by communicating with the users through interviews. The system consists...
This paper reports specifically on the architectural and design issues associated with the development of Web portal that will act as a conceptual platform of online utilities that enable users to collaboratively author and manage cultural resources in the globally distributed environment, featuring a Web-based portal with multifaceted interfaces that can additionally be utilised as an educational...
