Saehoon Kang et al. 545 This paper presents an efficient semantic service discovery scheme called UbiSearch for a large-scale ubiquitous computing environment. A semantic service discovery network in the semantic vector space is proposed where services that are semantically close to each other are mapped to nearby positions so that the similar services are registered in a cluster of resolvers. ...

Space allocation of urban facilities is a critical field of decision making in urban planning. Supposing that Geographic Information (GI) provide us with more objective parameters for space allocation, Geographic Information Systems (GIS) is used by urban planners. But usage of GIS in urban planning is limited to simple analyses believing that complex spatial analyzes complicate the currently e...

Recent advances in wireless and mobile networking technology pose a new set of requirements and challenges that are not previously thought of, when it comes to smart space middleware design. Leading the list is how to embrace diversity and unpredictability inherent in mobile computing environments. Service-oriented computing is being recognized as one of viable solutions to the problem. Accordi...

Resource location (or discovery) is a fundamental service for resource-sharing environments: given desired resource attributes, the service returns locations of matching resources. Designing such a service for a Grid environment of the scale and volatility of today’s peer-to-peer systems is not trivial. We explore part of the design space through simulations on an emulated Grid. To this end, we...

With the rapid development of information technology, it is inevitable that the distributed mobile computing will evolve to the pervasive computing gradually whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Furthermore, with the development of SOA, more and more pervasive applications have been composed...

In the era of ‘digital by default’, internet-borne services reach out into spaces and places. One example of such a service is home-based micro-payments using Internet Protocol Television (IPTV) that depends on reliable information-sharing practices between user and service providers. Traditional business modelling and brainstorming methods struggle to articulate the influences of space and pla...
