Formal concept analysis is an effective tools for knowledge discovery, information retrieval, machine learning, software engineering, etc.., The attribute reduction of concept lattices can reduce the complexity of concept lattices. Concept lattice is the central notion of a formal concept analysis, a new area of research which is based on a set-theoretical model of concepts and conceptual hierarchies. This model yields not only a new approach to data analysis, but also methods for formal representation of conceptual knowledge. Several algorithms were proposed for the attribute reduction of concept lattices, such as the discernibility attribute matrix method, requiring all the formal concepts in concept lattices to be solved, which is also a difficult job. This paper proposes a fast algorithm to work out reduction attribute directly on object set, which reduces the complexity and the calculation of concept lattice structuring. Read More Read Less

Having been exposed to several tourism products and destinations, experienced, sophisticated and demanding travellers rely greatly on electronic media to obtain information about destinations, as well as to be able to communicate their needs and wishes to suppliers rapidly. The term Virtual reality is used to describe systems that attempt to replace much or all of the user’s experience of the physical world with synthesised 3D material such as figures and sound. With Virtual reality, the user finds himself in the same dimension as and is immersed within the data. Though there is a presence of Assam on various ICT media, the customer communication of the state is limited to presence only. The benefits and utility of ICT and Internet based tools for effective customer communication of Assam ass tourism destination is yet to be realised. Besides virtual tourism or pervasive environment architecture, etc are totally absent from the customer communication strategies of the state. Read More Read Less

The advent of the internet, the evolution of the World Wide Web (WWW), coupled with the e-learning paradigm has resulted in the availability of a plethora of learning resources on the Web. However, these resources are not being fully utilized to their greatest potential. Learners, educators and researchers seeking educational content usually spend a great deal of time sorting through resources on the web without satisfactory results. Most times, this is not because the information is not available, but because the techniques being applied by major search engines do not handle the semantics and personalization required in this context. In a bid to proffer a solution to the problem of discovering relevant resources online by different categories of users, this work presents an integrated framework for personalized information retrieval of educational content. The framework exploits semantic web technologies. Further work will include the implementation and testing of the framework. Read More Read Less
