Mobile user devices, such as smart phones have become the most popular high-end mobile devices far beyond just cellular communication devices. They will continue evolving toward being palm-top computers with the rapid development of wireless communications and platform technologies. This paper introduces our development of a semantic reasoner called MiRE4OWL to be installed onto the resource-limited...
In this study, methods to extract advertising reviews from shopping mall reviews are suggested. Advertising reviews are mostly written by companies and contain advertising contents. There are a few studies regarding the classification of opinion spam documents, which is very rare in foreign studies; however, there are no studies that classify advertising reviews from Korean reviews. In this study,...
Flux pinning characteristics of grain aligned high- Tc superconductor Sm1-xEuxBa2Cu3O7-s (where x=0.0, 0.3, 0.5, 0.7, 0.9) were studied by magnetization data. Samples were prepared by solid state reaction and aligned under high magnetic field of 6 T. Results show that the transition temperature Tc and critical current density Jc was found to enhanced in optimal doped samples (x = 0.5-0.7). Peak positions...
It is inherently allowed that a user engages in more than one activity at the same time. The interweave of multiple activities makes an activity have more than two states, i.e. the paused state in addition to active and inactive states and move from one state to another. In this paper, we propose an activity lifecycle management scheme that enables a system to adapt the services which help a user...
This paper presents XVMF, an extensible and versatile matchmaking framework, which supports various service substitution mechanisms in dynamic application adaptation for ubiquitous computing environments. XVMF enables various substitution mechanisms to be easily developed by providing common abstracts for implementing a service substitution mechanism. It also allows an application or a user to select...
