Skilling unquestionably plays the most practical role in creating innovations which will be financially, socially and economically sustainable in developing countries (DCs). And because we now live in an economic age dependent on knowledge and driven by the rapid and global advances in Information and Communication Technologies (ICT), skilling in ICT is even more important. Key to participating...

When planning a trip, one essential task is to find a set of Places-of-Interest (POIs) which can be visited during the trip. Using existing travel guides or websites such as Lonely Planet and TripAdvisor, the user has to either manually work out a desirable set of POIs or take pre-configured travel packages; the former can be time consuming while the latter lacks flexibility. In this demonstrat...

Companies that have implemented PCSs have achieved substantial benefits in terms of being more in control of their product assortment, making the right decisions in the sales phase and increasing sales of optimal products....

Multi-context systems are a formalism for interlinking knowledge based system (contexts) which interact via (possibly nonmonotonic) bridge rules. Such interlinking provides ample opportunity for unexpected inconsistencies. These are undesired, and come in different categories: some are serious and must be inspected by a human operator, while some should simply be repaired automatically. However...

There has been a growing desire for methodological support for the development of knowledge based systems, and the KADS methodology is probably the most widely known methodology in Europe. However, KADS has been criticised for the overhead which it places on small and medium-sized KBS projects where the risks of KBS development becoming unmanageable are relatively low. This paper describes the ...

An adaptive knowledge system needs massive knowledge. But massive knowledge can handicap the speed of searching and reasoning. Good structure can considerably enhance the expressive power and efficiency of a knowledge system. Inspired by the structure of human memory and data warehouse, object-oriented warehouse architecture of knowledge based on the 3-World model was advanced after exploring t...

To save time and cost in assembly process and to improve the quality of products, it is very important to choose an optimal assembly sequence. In this paper, we propose a methodology that generates an optimal assembly sequence by using various methods and the knowledge of experts. To illustrate the effectiveness of the proposed methodology, a knowledge-based system is developed. The built syste...
