He objective of this paper is to demonstrate that sharing the vocabulary for service description enhances the service discovery mechanism. The proposed solution is a distributed architecture for enhanced context-aware web services. The starting point is a motivation scenario in which university students are trying to share a solution about a specific problem in a campus environment. The proposed solution...
The intrinsic nature of distributed software development (DSD) brings new challenges, such as communication issues and sharing information efficiently. Software companies have a tendency to face these challenges using individual and isolated approaches, making difficult to spread good practices for the DSD community. In other contexts, concepts and techniques from Artificial Intelligence (AI) are...
A challenging and demanding task for the teachers and researchers in e-learning environments is the assessment of students' performance. This paper is to present a new Learning analytics system for Learning Management Systems (LMS), that will aid and support teachers and researchers to understand and analyze interaction patterns and knowledge construction of the participants involved in ongoing online...
In the past few years, the advances in context-aware systems and sensor technologies, has elevated the Internet of Things (IoT) development greatly and rather quickly. Services of IoT systems must be reasonably designed to provide not only the user's requirements and requests, but also perceive the environmental context and customized services to get user's satisfaction. Systematic modeling methodologies...
Clinical data are crucial for any medical case to study and understand a patient’s condition and to give the patient the best possible treatment. Pervasive healthcare systems apply information and communication technology to enable the usage of ubiquitous clinical data by authorized medical persons. However, quality of clinical data in these applications is, to a large extent, determined by the technological...
Context information and context-awareness are some of the drivers for the Internet-of-Things paradigm, whereas a well-stated and defined model is the key element of any context information system. An appropriate context model ensures that the information gathered by a context information system can be represented, manipulated and accessed, and even linked to different systems and domains. This paper...
Currently, Web of Things is based on keyword matching which is not beneficial to the development regarding Web of Things. Accordingly, "Semantic Web of Things" is proposed. As far as Semantic Web of Things concerned, the information of things should be represented as ontology-based semantic annotation, and the information of things should be utilized as ontology-implemented semantic understanding...
Taking advantage of the improving Mobile Web technologies, mobile language-learning systems plays an important role for self-learning, especially in the case of working people. Nevertheless, existing systems do not support learners in studying or practicing language materials related with the current context. As it is known, the context related with surroundings can deepen the impressions and naturally...
Cloud Computing paradigm motivates researchers from both industry and academia with lot of research issues. Right from small and medium sized businesses and large scale businesses and even a single individual start utilizing cloud for their demands in terms of storage, software as well as infrastructure elastically and pay on use basis. But this transition to the cloud poses many security issues....
There is currently lot of work in Ambient Intelligence particularly in context awareness. Context awareness enables service discovery and adaptation of computing devices for Ambient Intelligence application. In the same time, there is a common agreement of the fact that context aware systems should be responsive to Multi agents, assisting a large number of people, covering a large number of devices,...
The use of web services in the field of e-learning has increased, however, in view of the significant number of these services; proper selection is needed to improve their effectiveness and contribution. We propose in this paper a system of personalized web service recommendation during online training. The objective is to assist learners in their learning activities (individual exercises, group problem...
Collaborative learning environments bring together learners from different cultures and social contexts, around a common task. These learners interact both with each other and with computers. Hence, a dual problem arises: how to model and integrate socio-cultural factors that characterize these learners? How to design and develop culture-aware collaborative learning environments? This paper addresses...
This work deals with Interaction Protocol (IP) adaptation for Business Processes (BP). BP describes the coordination of the actions performed by involved participants. One possible way to deal with this coordination is the use of interaction protocols (such as contract net, negotiation or vote). In order to guarantee an efficient use of IP, we need to adapt them. In this paper, we propose an MDA (Model...
Trust and quality maintenance have always been problematic in the Semantic Web RDF bases. Numerous propositions to address these problems of data integration have been made, either based on ontologies or on additional metadata. However ontologies suffer from a adaptation speed slower than the data evolution speed and metadata requires ad-hoc manipulations of data by addition of extra-data. In this...
The concept of System-of-Systems (SoS) presents a high level perspective that explains the interactions between independent subsystems. In the context of SoS, the issue of interoperability is crucial especially when integrating multiple heterogeneous and independently governed systems. Any solution is naturally applied to resolve a problem in a precise context, where context specificities are implicitly...
Nowadays location-based services become more and more popular. People travel from one location to another and usually would like to know information about places of interests around. Integration of location-based services with vehicles onboard systems opens new possibilities for delivering useful information about places of interests around using the vehicle multimedia system and voice control possibilities...
In the last years, the increasingly use of ICT in Healthcare has led to the generation of several healthcare information systems, such as Electronic Health Record systems, which enable the management and sharing of digital clinical data. Since clinical data is generally characterized by very sensitive information, such information systems have to be able to limit their sharing of it, by enabling or...
This paper discusses a framework for the design of business services, called Service System (SS). SSs are a layer built on the top of Internet of Things (IoT) and Internet of Services (IOS). SSs integrate two components, Internet of Business (IOB) and Internet of Data (IOD). IOB delivers complex business services that combine services from IOS and IOT. In turn, IOD links semantically the information...
Nowadays, collaboration in the scientific domain has been discussed in several papers. Its relevance is justified by some classical problems, such as lack of support for the composition of scientific workflows, the difficulty in reusing scientific applications and in supporting cooperation and communication between geographically distributed teams of scientists, among others. Approaches such as SPL...
Preparing for the energy crisis, many research and development are underway to reduce the energy consumption and consume the energy more efficiently. BEMS (Building Energy Management System) is one of the essential technologies for saving the energy in the field of building. Commonly, existing BEMS is operated and controlled by the system operators or energy experts manually and also provides limited...
