It is time for these two be blended and provide ubiquitous access and interoperability online. We are approaching Internet of Things -a forthcoming technological revolution that will radically change our environment and enable innovative applications and services. To make this happen, we have to eliminate the fragmentation in used technologies and have to make the devices be used across various applications and services. We need to find a way to actually carry out the necessary and massive deployment of ubiquitous devices. So we need to put more effort into the design of tools to automate deployment and configuration of devices. This paper tackled a problem of an effective way to support interoperability in Internet of Things. We consider human as a very powerful asset in the world of ubiquitous systems and services that may provide his/her knowledge, experience and expertise. At the same time, we see a lack of human-oriented systems and infrastructures to support such a new role of a human. With a respect to the above statements, authors propose visually-enriched approach for user-powered ontology alignment to facilitate semantic interoperability in the Web of Things.

Resource Description Framework (RDF) is a basis for explicit and machine-readable representation of semantics. However RDF is not suitable for describing dynamic and context-sensitive resources (eg. processes). We present the Context Description Framework (CDF) as an extension of the RDF by adding a 'TrueInContext' component to the basic RDF triple ('subject-predicate-object'), and consider contextual value as a container of RDF statements. We also add a probabilistic component, which allows multilevel contextual dependence descriptions as well as presumes possibility for Bayesian reasoning with the RDF model.

Resource Description Framework (RDF) 1 is the basis for explicit and machine-readable representations of semantics of various Web resources and enables a framework for interoperability of future Semantic Web-based applications. However it has been pointed out that RDF is not suitable for describing highly dynamic and proactive resources (e.g. industrial devices, processes, etc.). Therefore, an appropriate extension of the existing RDF is necessary. This paper presents the Proactivity Layer of the Smart Resource in Semantic Web with the Resource Agent Behaviour definition. Process performance strategies and coordination methods of such proactive goal-driven resources are considered.

It facilitates scalability and virtualized resources over the Internet as a service; providing cost effective and scalable solution to customers. There are two emerging methodologies for constructing infrastructure: "Cloudcenters" and "Infrastructure Web Services". Cloudcenters can be regarded as a virtualized data center. Infrastructure Web Services are more analogous to Service-Oriented-Architectures (SOA), require significant programming skills and are much more comfortable for software developers. It is a robust ecosystem of services which you can use in order to build your application, getting the traditional benefits of Cloud Computing such as self-service, pay-as-you-go, and massive scalability. Unfortunately, talking about openness and interoperability in cloud computing, cloud providers still operate very much in their own silos and private-cloud APIs drift further and further apart. Most data center vendors do not offer users complete vertically integrated cloud stacks. However, they are often providing solutions which imply a strong vendor lock-in. A lot of activities are currently aimed at the development of various Cloud computing environments and software engineering practices for the management of distributed applications, services and other resources. We are thinking about a future vision of a network of clouds. It should be an open market for components (applications, services, data sources, etc.) and composed ecosystem infrastructure services that facilitate appropriate collaboration for personalized needs. In this paper we would like to slightly modify the original cloud stack towards the development of an open environment for taskoriented personalized cloud ecosystems and apply a resource integration platform for this ecosystem elaboration.

Sooner or later, changes in ICT domain and new digital technologies might reach the education process development and lead to innovations in this area. Advance educational services and platforms should aim to develop an environment that is not bound to location or time, that makes it possible to access information anywhere, anytime, and in more suitable and personalized for user form. eLearning and augmented reality offer high potential for interactive materials that could enrich the learning experience. Thus, our environment and context can be integrated into the learning process. This brings the education to a new level. This paper tackles two issues that lie between technological world and education domain. First issue concerns mashup based supportive platform for collaborative study content creation. Another issue concerns human adaptation and technological world consumption in personalized education process.

The new era is characterized by open business service ecosystems where partners can relatively safely detect new potential partners, establish new flexible business models, create an open market of business services to jointly utilize, and to rely on service interoperability utilities. This paper tackled some of the challenges of Ubiquitous Services vision that will be a perfect base for new era of business ecosystems with increased human capabilities of service consumption. Author show how service integration solutions might open new possibilities for collaborative services creation; how consumption of technological achievements might open new business opportunities and help to build new collaborative business models.
