Purpose: The purpose of this paper is to describe TraceALL which is a Semantic Web (SW), ontology-based, service-oriented framework which aims to provide the necessary infrastructure enabling food industry (particularly SMEs) to implement traceability applications using an innovative generic framework. Design/methodology/approach: The framework builds upon the idea of the Semantic Web and provides an open and extensible underlying platform that allows different traceability interconnected applications to be designed and developed. More specifically, the framework provides a formal, ontology-based, general-purpose methodology to support knowledge representation and information modelling in traceability systems. Additionally, it suggests an open application framework based on widely used Semantic Web standards. Finally it provides a set of core services for storing, processing and retrieving traceability information in a scalable way. These components, taken together, facilitate the efficient development of next generation traceability applications. Findings: Based on a case study which the authors executed as a proof of concept and studying the relevant literature it was found that TraceALL facilitates the development of next generation traceability applications because, from a food safety perspective, it enables all stakeholders in the food supply chain to have an information trail that follows the product's physical trail, but at the same time is cost effective, easy to manage and applicable within a globalised, networked, interoperable economic environment. Originality/value: To the best of the authors' knowledge, this is the first food traceability system based completely on solid existing standards of the Semantic Web initiative. The authors consider that the inspiring analogy between resources such as those described in the Semantic Web initiative and the core traceability concept of a Traceable Resource Unit (TRU) is an extremely useful concept for developing cost-effective traceability applications that possess many key requirements, which are described in the paper. © Emerald Group Publishing Limited.

Mobile devices are becoming more powerful and are able to support applications of significant size and high processing efforts. However, most of the applications require mobile internet connections to use information and services of background infrastructures. Especially business applications for mobile devices consisting of a dashboard that provides the user with information and a service orientated architecture behind which provides the correspondent services to collect the required information. The development of such a business application and the background service infrastructure requires not only lots of know-how, but is also very expensive. This paper presents the MO-BIZZ platform that allows businesses to rapidly develop and offer new services to their customers. In fact, the MO-BIZZ platform enables autonomous organizations to deploy additional services and the combination and validation of existing cloud-based services from third-party provider. Thus, companies are able to save money for developing common business functionality and a complex background infrastructure for its provisioning. The challenge of this innovative technology is not only related to the development of a business model that shall facilitate rapid service conceptualization, but rather the service level agreements that need to be dynamically negotiated and accepted on different levels of the MO-BIZZ stack. © 2014 IEEE.

The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered for free or purchased through some central form of a marketplace repository. © 2014 Springer-Verlag Berlin Heidelberg.

The provision of the Health services in the EU despite the evolvement of ICT follows a rather traditional path were the patient is totally dependable from his/hers doctors seeking guidance for every decision he/she needs to take related to his/her condition. The vision of the iCare approach is to provide better support to patients from the comfort of their home. This paper presents a new innovative approach to improve Patient Guidance Services (PGS). iCare approach takes full advantage of Semantic Web technologies and IoT and provides a new approach that would put the demands of the patient in the center and exploiting the available sources it will offer patient guidance services reducing dramatically the patient dependency from his/her doctors. © Springer-Verlag Berlin Heidelberg 2013.

In order for a user to develop rich and valid knowledge structures, not only is considerable predefined content required, but other equally important types of knowledge as well. In other words, to display real understanding and to build and extend their knowledge structures, users have to call on several resources as well as representation, retrieval and construction mechanisms. Apart from the specific content, on which traditional educational environments focus on, a user depends heavily on general content knowledge and on systems of knowledge that is more abstract and elusive than typical content. In this article, we document our myCourse approach presenting three application scenarios. In these scenarios, knowledge creation is a process of emergence and co-evolution of the individual, the social group and the wider society.

Companies that introduce environmental accounting principles in their management accounting system can significantly benefit from lower energy bills and greater efficiency in their operations. However, environmental accounting is a difficult task, especially for small enterprises or SMEs, as it requires a significant proportion of their limited resources. This paper presents EnvAcc, a software shell that aims to integrate environmental accounting services with ERPs in a flexible, configurable way. The system is developed using open source tools and open architecture standards, such as PHP, MySQL, Javascript and Linux. The user interface is web-based to achieve a convenient user experience. © 2010 Elsevier Ltd.

Recent studies show that over the last decade electronic systems designed, created and continuously developed with the common goal to help the elderly live a more independent life. Each of the existing electronic systems offer services that cover different needs of ageing people living, such as self-determined life at home, social interaction, etc. In this paper we propose a set of service components that constitute a model for an e-service architecture capable to support the autonomy of older people. Furthermore, we argue that by exploiting existing operational electronic systems and integrate them according to the services they offer we can possibly converge to an ideal system that enhances assisted living of elderly people. © 2010 International Federation for Medical and Biological Engineering.
