Recent research in pervasive computing and distributed decision support systems aims to enable users to share knowledge easily to support one another in problem solving in a manner that adapts to their varying contexts of work. However, existing approaches, most often, are restricted by formal models of task analysis and, as such, are not able to capture the informal work practices, which workers...
In this paper we define an ontological model to accurately represent the context in Pervasive Computer Supported Collaborative Work. A major issue in this domain is the mass of information required to correctly depict a situation. As we need to represent users and devices according to multiple aspects (physical, computational, social ...) the amount of information can quickly become unmanageable....
In present day globalised trade, the ability to support collaboration through B2B (Business-to-Business) services is crucial. One of the key challenges is to pervasively connect partners across the entire value chain, with the appropriate service offerings. Thus, it is vital to quickly identify potential partners to form new B2B collaborations or to support formed collaborations with swift decision...
Interoperability is a collaborative and multifaceted task to overcome the problems of incompatibilities among organizations, structures, data, architecture, services, and business rules. To achieve interoperability, the aspect for interoperability and requirements for applications and services must be known. SC3 provides Ubiquitous Life Care (u-Life care) for robust healthcare services, service suggestions,...
To adapt communication in order to maintain the connectivity and the quality of communications in group-wide collaborative activities becomes challenging when considering mobile entities in a wireless environment, requiring responsiveness and availability of the communication system, and designing self-adaptable communication architecture remains a complex task. To simplify this task, semantic presents...
With the ongoing trend towards the globalization of software systems and their development, components in these systems might not only work together, but may end up evolving independently from each other. Modern IDEs have started to incorporate support for these highly distributed environments, by adding new collaborative features. As a result, assessing and controlling system quality (e.g. security...
In order to realise the goals of e-health, future e-health systems will require the capability to support patientspsila information management and medical decision making in an open and dynamic ubiquitous medical environment. Such an environment will be knowledge-rich, and sensitive and responsive to the needs of patients, and will allow effective collaborative healthcare service delivery by virtual...
News@hand is a news recommender system that makes use of semantic technologies to provide several on-line news recommendation services. News contents and user preferences are described in terms of concepts appearing in a set of domain ontologies. Based on the similarities between item descriptions and user profiles, and the se-mantic relations between concepts, content-based and collaborative recommendation...
In pervasive computing environment, collaboration between participants and interacts between applications are key characters of pervasive computing. In order to support those collaborative activities, we propose an ontology based workflow centric collaboration system modeling method. We build the collaboration system models in different abstraction layers according to domain related degree. Based...
Context represents a fundamental issue in research into pervasive and cooperative computing applications. This paper presents a survey on context modelling issues, together with a discussion on approaches to context modelling in intelligent context-aware pervasive systems. There is a parametric evaluation of the approaches considered, the conclusion drawn being that ontology-based modelling approach...
Context awareness, context sharing and context processing are key requirements for the future CSCW, HCI and ubiquitous computing systems. Until now, the collaborative context factors have been seldom specifically addressed. This paper argues that a generic context model is very important for building context-aware collaborative applications. A new semantic rich context model for collaborative environment...
Traditional distributed collaboration frameworks based on assumption of static collaboration and usage patterns cannot fulfil many new requirements imposed by today's collaboration with heterogeneous and ever-changing environments and computing contexts. In this paper, we describe a collaboration framework, called as EkSarva, which enables adaptability by providing context-awareness through a set...
