A versatile architecture for federating mEducator 3.0 instantiations

Abstract: 
The mEducator ontology has been designed to provide a consistent data scheme, across the various mEducator instances. As the installations get enriched with educational content, resource discovery, retrieval, sharing and reuse becomes more complicated. Consequently, advanced search features are needed to avoid content duplication and assist the learners in conveniently locating relevant content. To integrate the search functionality of the deployed platforms into a single access point, the search federation service was developed. The service exploits SPARQL 1.1 query-federation functionalityto request information from multiple SPARQL endpoints. The core of the service is based on a Joseki RDF server, which, in turn, is wrapped by an HTTP interface, developed in PHP. The service clients can use a simple syntax to define filters and returned fields, as well as, common Boolean operators and other parameters. In order to test the service, the AUTH mEducator team developed two clients, for its educational platforms. Successful completion of the these test has indicated that this architecture offers a much versatile and flexible method for federating mEducator3.0 instantiations, thereby allowing for a proper sustainability and exit strategy plan for mEducator.

Extending Moodle2.0 in the semantic and social media spaces for Linked Medical Learning: the mEducator3.0/MILES+ approach

Abstract: 
During the last decades Learning Content Management Systems have experienced an enormous expansion. Proprietary and open source systems have been installed and heavily used across many different institutions. In the new era of semantic web, linked data and social media, it is imperative that LCMSs could not remain unaffected. In terms of this context and taking into consideration mEducator Best Practices for sharing medical educational resources, we have adjusted and further expanded Moodle, an open source LCMS, used by some 57 million users and containing over 53 million resources. The new LCMS, namely Medical inter-Linked Educational Space (MILES+), allows users to properly describe or update their educational resources with mEducator ontology and share them with the rest of the medical educational community by the means of Linked Data through the use of a D2R server. To this extent, mEducator resources form federated systems may be searched, retrieved and inserted into MILES+, without requiring the user to leave his institutional LCMS and search across other systems. In addition, an enhanced educational experience for the user is taking place, since resources from the Linked Open Data Cloud (LOD) are proposed as relating to the platform’s resources thereby enriching the resource context; a geographical representation of the resources is taking place while WEB2.0 technology fosters online collaboration between users.

Extending Drupal7.0 in the semantic and social media spaces for Open Linked Medical Education: the mEducator3.0/MELINA+ approach

Abstract: 
Drupal is one of the most widely used content management systems, which currently empowers a large number of web sites. In the latest version, semantic web technologies are part of Drupal's core DNA. Until now, exposing information to the Web of Data required considerable expertise in RDF and additional programming effort. The mEducator3.0/MELINA+ is an extended version of Drupal 7; it is offered as an installation profile and enables web site administrators to install a learning management system, which is focused in medical education. Users can create RDFa annotations based on the mEducator schema without any special technical knowledge. A series of features, such as the SPARQL endpoint and the DBpedia spotlight annotation, allow networked sites to re-use and enrich the linked data. The WebID authentication and the FOAF profile modules, transform the content creation process into a socially oriented collaboration and learning experience. When brought together, all these features offer new possibilities to create networked web applications in the medical education space and open the semantic web area to a much larger community of users and administrators.

Towards an embedded semantic wiki for user training in an ePrescribing service

Abstract: 
Electronic Prescribing (ePrescribing) has been introduced as a solution to improved patient safety and reduced medication costs and therefore, web-based technology should be fully embraced in the pharmacy industry as an aid to quality-assuring prescribing processes. Hence, healthcare information systems are facing the challenge of attempting to satisfy the needs of both novice and expert users, focusing on a high likelihood of physician adoption of ePrescribing. Well-defined ePrescribing processes and interoperable health IT will enable virtual care teams to cooperate in the care of patients across organizational boundaries and may conduct to ePrescribing adoption. However, it should be highly considered that successful healthcare process design requires active participation of users who are familiar with the cooperative and collaborative nature of healthcare delivery, expressed in terms of healthcare processes. Therefore, an ePrescribing service that premises a reusable, flexible, agile and adaptable training content with the objective to enable healthcare professionals cooperate, in order to instil their knowledge and expertise in the ePrescribing process management and (re)configuration activities, it is required. To this end, social software, such as a wiki, could be used as it supports cooperation and collaboration anytime, anywhere and combined with semantic web technology enables structuring pieces of information for easy retrieval, reuse and exchange between different systems and tools. In this approach a semantic wiki is proposed as a means for providing embedded training material for healthcare providers, regarding ePrescribing process management that acts as a collective online memory containing training material accessible to authorized users upon request, thus enhancing the training process with collaboration and cooperation capabilities. The semantic wiki may increase the likelihood of ePrescribing adoption by healthcare professionals as it offers them guidelines on how to perform each task of the ePrescribing service.

Virtual patients on the Semantic Web: the mEducator3.0/Linked Labyrinth Plus approach

Abstract: 
LLplus (Linked Labyrinth+) is a mEducator3 based on a semantic extension of OpenLabyrinth. It allows OpenLabyrinth users to integrate and share their Virtual Patient’s metadata within mEducator 3.0. Although the core version of OpenLabyrinth does not support extended repository functionalities, LLplus enriches the global metadata describing a Virtual Patient, by applying the mEducator schema on the existing OpenLabyrinth Global Metadata Editor. The Linked Labyrinth Plus approach allows Virtual Patients to be available on the Semantic Web, while it also provides a search mechanism to educational resources that exist in other LCMSs and repositories. The architecture is based on a D2R server that exposes the mEducator metadata to RDF triples and linked data, thereby allowing the connectivity with the Linked Open Data Cloud.
