Building automation systems control many aspects of today's buildings - lightning control, air condition, shading, access control, and surveillance, just to name a few. This diversity and the diversity of related technologies and protocols entails that the extension or integration of building automation systems requires a major effort. To address these challenges, the ITEA3 Building as a Service (BaaS)...
Nowadays, mobile devices are the first choice for seeking information and content consumption on the Web. However, the overwhelming amount of available web resources, significantly affects the quality of the results returned by search systems. Traditionally, the web resource's retrieval is performed by using syntactic and/or semantic matches between the user query and content of the resources, leaving...
IoT/Bigdata is a hot research topic all over the world in recent years and is expecting to change the world greatly in the near future. Comparing with the data in traditional websites, Bigdata from IoT devices have 4 big V-features, i.e., volume, velocity, variety, and veracity. Due to the above four features, it is hard to provide timely services to users by data analysis, especially with the great...
With the constantly growing number of multimedia devices, images can now be viewed on a broad range of display of tremendously varying size. However, perceiving all the details of a multimedia content is difficult on smaller mobile devices. To solve this problem, saliency based image re-targeting algorithms have been proposed in order to generate more perceptually efficient thumbnails. In this article,...
Cloud computing based Data-as-a-Service (DaaS) has become popular. Several data assets have been released in DaaSes across different cloud platforms. Nevertheless, there are no well-defined ways to describe DaaSes and their associated data assets. On the one hand, existing DaaS providers simply use HTML documents to describe their service. This simple way of service description requires user to manually...
With the rapid expanse of the web service over the internet, discovering relevant web services becomes a significant challenge. To tackle this problem, a service-discovering framework based on behavioral equivalence is proposed in this paper. First, pi-calculus as a formal tool is adopted to express service behavior, including the published services and the query services. Then, the reverse engineering...
Web Services providing access to datasources with structured data have an important place in the SOA. In this paper we focus on modeling and discovery of generic data providing services (DPS), with the goal of making data providing services available for interactions with service requesters in contexts such as service composition and mediation. In our model RDF Views are used to represent the content...
A community cyberinfrastructure would enable a new era of multidisciplinary research and collaboration in science and engineering. With such an infrastructure, researchers could share knowledge and results along with computing cycles, storage, and bandwidth. A generic, transparent cyberinfrastructure would also foster more meaningful analyses of data and visualization, modeling, and simulation of...
