In this paper we analyse the applicability of our ontology based context modelling approach, considering a range of use cases. After wrapping up the model and the Context Ontology Language (CoOL) derived from it, we introduce some interesting applications of the language, based on a scenario showing the challenges in context aware service interactions. We focus on two submodels of our model for...

Serious Games (SGs) have a lot of potential in education, possibly making learning more engaging and satisfying. Adaptive Games strive to keep the challenges presented by the game balanced with the player’s abilities, as to keep the player in the “flow” state. We have used a Service-Oriented Architecture (SOA) approach to develop a simple adaptive SG for teaching basic elements of probability t...

Service-oriented computing is an emerging IT innovation. Among its manifestations is service-oriented architecture (SOA), an architectural approach to designing and implementing IT solutions. Academic empirical research on SOA adoption is scarce, with many studies focussing on qualitative analysis. The purpose of this study is to explore SOA adoption using a quantitative approach. This study in...

Recently, service-oriented paradigm is emerging as a new pattern following process-oriented and object-oriented ones in systems analysis and software development. Service-oriented High Level Architecture (SOHLA) refers to the high level architecture (HLA) enabled by Service-Oriented Architecture (SOA) and Web Services etc. techniques which supports distributed interoperating services. The detai...

Service-Oriented Computing (SOC) is a new computing paradigm that utilizes services as the primitive computing unit to support development and composition of larger-granularity services in heterogeneous environments. The specification and execution of services in such environments is meant to support agility in application structures, flexibility for business processes and development of applic...

Service-oriented computing is becoming an increasingly popular paradigm for modelling and building distributed systems in open and heterogeneous environments. However, proposed service-oriented architectures are typically based on centralised components, such as service registries or service brokers, that introduce reliability, management, and performance issues. This paper describes an approac...

Service Oriented Architecture (SOA) has been proposed as model for distributed software development that surpasses the traditional Distributed Object Architecture (DOA) practices in many areas. However, no empirical studies have been conducted to verify the claimed benefits. This study is a first attempt at presenting empirical evidence regarding the benefits of SOA. It is a comparison between ...

The Low-Power Wireless Personal Area Networks (LoWPANs) have been recognized as a promising technology for ubiquitous and pervasive computing systems. However, LoWPAN technology is still open to being adapted to existing interoperability mechanisms defined for the Internet. Service-Oriented-Architecture (SOA) is one of the key paradigms that enables the deployment of services at large-scale ove...

When similar business processes are deployed in different organizations, one typically adapts manually a template process to the different execution environments and organizational needs. Service-Oriented Architectures facilitate the task of adaptation by exposing the functionalities needed by the process in an abstract way, decoupled from the implementation. Nevertheless, manual intervention t...

Service-oriented architectures evolved rapidly as the solution to the latest requirements for loosely-coupled distributed computing. Into this broad context several approaches emerged towards the discovery and the systematic composition/orchestration of services. One of the next challenges in this field is the maintenance of service-oriented architectures towards accomplishing the ultimate goal...
