Towards runtime discovery, selection and composition of semantic services

Service-orientation is gaining momentum in distributed software applications, mainly because it facilitates interoperability and allows application designers to abstract from underlying implementation technologies. Service composition has been acknowledged as a promising approach to create composite services that are capable of supporting service user needs, possibly by personalising the service delivery through the use of context information or user preferences. In this paper we discuss the challenges of automatic service composition, and present DynamiCoS, which is a novel framework that aims at supporting service composition on demand and at runtime for the benefit of service end-users. We define the DynamiCoS framework based on a service composition life-cycle. Framework mechanisms are introduced to tackle each of the phases and requirements of this life-cycle. Semantic services are used in our framework to enable reasoning on the service requests issued by end users, making it possible to automate service discovery, selection and composition. We validate our framework with a prototype that we have built in order to experiment with the mechanisms we have designed. The prototype was evaluated in a testing environment using some use case scenarios. The results of our evaluation give evidences of the feasibility of our approach to support runtime service composition. We also show the benefits of semantic-based frameworks for service composition, particularly for end-users who will be able to have more control on the service composition process

A Process Framework for Semantics-aware Tourism Information Systems

The growing sophistication of user requirements in tourism due to the advent of new technologies such as the Semantic Web and mobile computing has imposed new possibilities for improved intelligence in Tourism Information Systems (TIS). Traditional software engineering and web engineering approaches cannot suffice, hence the need to find new product development approaches that would sufficiently enable the next generation of TIS. The next generation of TIS are expected among other things to: enable semantics-based information processing, exhibit natural language capabilities, facilitate inter-organization exchange of information in a seamless way, and evolve proactively in tandem with dynamic user requirements. In this paper, a product development approach called Product Line for Ontology-based Semantics-Aware Tourism Information Systems (PLOSATIS) which is a novel hybridization of software product line engineering, and Semantic Web engineering concepts is proposed. PLOSATIS is presented as potentially effective, predictable and amenable to software process improvement initiatives

Research Into Technological Indicators of a Rye-wheat Dough Semi-finished Product with the Addition of the Polyfunctional Food Supplement "Magnetofооd"

We studied influence of the polyfunctional food supplement "Magnetofооd" on the technological parameters of rye-wheat dough semi-finished product and the finished product. A positive effect of the supplement "Magnetofооd" on the technological parameters of dough and the bread baked using it, is shown. It was established that adding the food supplement "Magnetofооd" in the amount of 0.15 % of the weight of flour reduces dough fermentation time by 13.0 on average %. The introduction of the food supplement "Magnetofооd" also increases the yield of a dough semi-finished product by 2.9 % on average and improves the yield of the finished product by 3.45 % on average. It was revealed that the multifunctional food supplement "Magnetofооd" enhances the quality of rye-wheat dough semi-finished product and the finished product due to its capacity of moisture retention and the inhibition of hydrolysis processes of the basic ingredients of dough.The obtained experimental data could be used to develop a technology of rye-wheat bread, enriched with the polyfunctional food supplement "Magnetofооd"

Influence of Harvesting Stages, Drying Structures and Drying Durations on Oleoresin and Essential Oil content of Korarima (Aframomum corrorima (Braun) P.C.M. Jansen) Capsules Grown in Ethiopia

Korarima (Aframomum corrorima) capsules face stringent market challenges, due to its inferior oleoresin and essential oil content. The inferior quality is owed to harvesting stages, drying structures and durations. Hence, this study was conducted to address such issues and to enhance oleoresin and essential oil content. The experiment consisted of harvesting stages (Mature Green, Mature Semi-red and Mature deep Red), drying structures (Cement, Ground and Wire mesh bed) and drying durations (10, 15 and 20 days) laid out in 3*3*3 factorial arrangement using Completely Randomized Design with three replications. Data on oleoresin and essential oil content of dried seeds and dried husk were recorded and subjected to ANOVA. The interactions were significantly affected quality of dried capsules. Mature green capsules dried on wire mesh bed for 10 days scored maximum oleoresin (10.04%) and essential oil content of dried seeds (5.53%) and essential oil of dried husks (0.93%). However, mature green and mature deep-red capsules dried on cement floor for 20 days gave minimum essential oil (2.82%) and oleoresin (4.88%) contents, respectively. Therefore, for extraction purpose, mature green capsules dried on wire mesh bed for 10 days can be recommended for optimum extraction quality. Keywords: Aframomum corrorima, Oleoresin, Essential Oi

Proceedings of the 1st international workshop on software process education, training and professionalism (SPETP 2015)

These Proceedings contain the papers accepted for publication and presentation at the first 1st International Workshop on Software Process Education, Training and Professionalism (SPETP 2015) held in conjunction with the 15th International Conference on Software Process Improvement and Capability dEtermination (SPICE 2015), Gothenburg, Sweden, during June 15-17, 2015. During the 14th International Conference on Software Process Improvement and Capability dEtermination (SPICE 2014) held in Vilnius, Lithuania, at a post conference dinner, a group of key individuals from education and industry started to discuss the challenges faced for software process education, training and professionalism, especially with the background of the new modes of learning and teaching in higher education. Further discussions held post conference with key players in the relevant professional and personal certification fields led to a consensus that it is time for the industry to rise to the new challenges and set out in a manifesto a common vision for educators and trainers together with a set of recommendations to address the challenges faced. It was therefore agreed co-located the 1st International Workshop on Software Process Education, Training and Professionalism with the 15th International Conference on Software Process Improvement and Capability dEtermination. This workshop focused on the new challenges for and best practices in software process education, training and professionalism. The foundation for learning of software process should be part of a university or college education however software process is often treated as ‘add one’ module to the core curriculum. In a professional context, whilst there have been a number of initiatives focused on the certification related to the software process professional these have had little success for numerous reasons. Cooperation in education between industry, academia and professional bodies is paramount, together with the recognition of how the education world is changing and how education is resourced, delivered (with online and open learning) and taken up. Over the next 10 years on-line learning is projected to grow fifteen fold, accounting for 30% of all education provision, according to the recent report to the European Commission on New modes of learning and teaching in higher education. It is a great pleasure to see the varied contributions to this 1st International Workshop on Software Process Education, Training and Professionalism and we hope that our joint dedication, passion and innovation will lead to success for the profession through the publication of the manifesto as a key outcome from the workshop. On behalf of the SPETP 2015 conference Organizing Committee, we would like to thank all participants. Firstly all the authors, whose quality work is the essence of the conference, and the members of the Program Committee, who helped us with their expertise and diligence in reviewing all of the submissions. As we all know, organizing a conference requires the effort of many individuals. We wish to thank also all the members of our Organizing Committee, whose work and commitment were invaluable
