Abstract The authors demonstrate how to use semantic Web technologies to improve the state-of-the-art in online learning environments and bridge the gap between students on the one hand, and authors or teachers on the other. The ontological framework presented here helps formalize learning object context as a complex interplay of different learning-related elements and shows how we can use semantic annotation to interrelate diverse learning artifacts.

Abstract. Nowadays, when social software tools and services have become the primary communication media and integral part of the new generation's personal lives, it is more than obvious that it is necessary to make them an integral component of educational context. Social software offers various advantages in educational context: they facilitate collaboration, knowledge sharing, group formation around common interests, active participation and reflective thinking.

Abstract This paper presents the process of identifying and describing cases for Technology Enhanced Learning (TEL) in a Small/Medium Enterprise (SME), as a part of an ongoing international TEL project. It proposes a template for describing TEL cases in an SME that collaborates with other organizations, notably with a university/research group. An example case description is used to illustrate the template proposed. In addition, the paper discusses how such a case is supported by specific TEL services on the Web.

Abstract Social software tools, being a core element of a PLE, support knowledge sharing [2] and community building [3]. Great majority of these social software tools favors direct and frequent communication among users and allows them to maintain their online presence. In a PLE, especially important is the notion of global online presence, ie, student's online presence expressed on different social tools integrated into his/her PLE.

Abstract The paper proposes a framework for building learning object (LO) content using ontologies. In the previous work on using ontologies to describe LOs, researchers employed ontologies exclusively for describing LOs' metadata. Although such an approach is useful for searching for LOs in LO Repositories, it does not provide us with features to reuse components of LOs, nor to incorporate an explicit specification of domain semantics into LO content.

Abstract. Determining the semantic relatedness (SR) of two terms has been an appealing topic in information retrieval for many years as such information is useful for various tasks ranging from tag recommendation, over search query refinement to suggesting new web resources for the user to discover. Most approaches consider the SR of terms as static over time, and disregard the eventual temporal changes as imperfections.

Abstract This paper reports on the development of TANGRAM, a learning environment for a subdomain of Intelligent Information Systems, fully based on ontologies. TANGRAM is devised to illustrate the benefits of applying Semantic Web technologies to achieve reusability on different levels of content granularity. Currently, it reuses components of existing LOs to generate personalized learning content. In this paper we first briefly overview TANGRAM's architecture and its main functionalities.

Abstract Recent research in learning technologies has demonstrated many promising contributions from the use of ontologies and semantic web technologies for the development of advanced learning environments. In spite of those benefits, ontology development and maintenance remain the key research challenges to be solved before ontology-enhanced learning environments are widely used.

Abstract This article reports on the development of a framework for repurposing learning object components, more specifically components of slide presentations. Unlike the usual practice where learning object components are assembled manually, the framework enables on-the-fly access and repurposing of learning object components. In earlier work, we have developed an ontology that formalizes structural aspects of learning objects.

Abstract. One of the main software engineers' competencies, solving software problems, is most effectively acquired through an active examination of learning resources and work on real-world examples in small development teams. This obviously indicates a need for an integration of several existing learning tools and systems in a common collaborative learning environment, as well as advanced educational services that provide students with right in time advice about learning resources and possible collaboration partners.

ABSTRACT This paper presents an ontology-based framework aimed at explicit representation of context-specific metadata derived from the actual usage of learning objects and learning designs. The core part of the proposed framework is a learning object context ontology, that leverages a range of other kinds of learning ontologies (eg, user modeling ontology, domain ontology, and learning design ontology) to capture the information about the real usage of a learning object inside a learning design.

Abstract This paper reports on the development of an ontology-based framework for content repurposing. In earlier work, we developed an ontology that formalizes structural aspects of learning objects. In this paper, we present a framework that uses this ontology and its underlying abstract content model to aggregate and disaggregate learning objects, more specifically slide presentations.

Abstract. Providing personalized and context-aware learning contents to the learners in mobile learning environments requires a precise and well-represented definition of the term “context” in such environments. In this paper we present an ontology-based framework, called m-LOCO, built on top of an integrated set of ontologies (eg learning design ontology, domain ontology, user model ontology and learning object ontology) with the goal of capturing contextual information in mobile learning environments.

Abstract In this design briefing, we introduce the Learn-B environment, our attempt in designing and implementing a research prototype to address some of the challenges inherent in workplace learning: the informal aspect of workplace learning requires knowledge workers to be supported in their self-regulatory learning (SRL) processes, whilst its social nature draws attention to the role of collective in those processes.

This paper presents an ontology-based framework for repurposing learning object components. Unlike the usual practice where learning object components are assembled manually, the proposed framework enables on-the-fly access and repurposing of learning object components. The framework supports two processes: the decomposition of learning objects into their components as well as the automatic assembly of these components in real-world applications. For now, the framework supports slide presentations.

Abstract This paper investigates basic research issues that need to be addressed for developing an architecture that enables repurposing of learning objects in a flexible way. Currently, there are a number of Learning Object Content Models (eg the SCORM Content Aggregation Model) that define learning objects and their components in a more or less precise way. However, these models do not allow repurposing of fine-grained components (sentences, images).

Today's technology-enhanced learning practices cater to students and teachers who use many different learning tools and environments and are used to a paradigm of interaction derived from open, ubiquitous, and socially oriented services. In this context, a crucial issue for education systems in general, and for Intelligent Learning Environments (ILEs) in particular, is related to the ability of leveraging these new paradigms for creating, maintaining and sharing the knowledge that these systems embed.

For a successful learning organization, it is of crucial importance to have successful methods for stimulation and sharing of working and learning activities of their employees. However, there are two important challenges to be addressed: i) combination of individual and organizational incentives that motivate employees to take part in knowledge building and sharing activities; and ii) structuring of learning and knowledge building activities and their outcomes in a representation that can assure unambiguous knowledge sharing.

Today's students, being used to constant activity and multitasking in their everyday life, need a high level of social and creative engagement in order to learn; for them, highly interactive learning environments which allow for communication, collaboration, and authoring, are a must. In addition, modern learning theories stress the importance of interactivity and engagement of students for successful learning processes, whereas recent empirical studies provide evidence and confirm this.

Abstract The creation of learning resource metadata by instructors is a time consuming and error prone process. This paper outlines a broad research agenda to mitigate these issues.. The first part of this approach is to collect prescriptive metadata from various actors involved using a light weight collaborative tagging approach. This is then augmented with content analysis done directly on learning objects to create concept and summarization metadata.

Abstract We present results of the end user study evaluating tools that use two distinct approaches to developing ontology from text material. Our aim was to examine a current state of support for a widespread assumption in many semantic Web application domains, such as eLearning, that the domain ontologies will be developed by not-ontology-savvy users. The results show that the users had hard time to use the tools and the ontologies produced are mostly of poor quality.

Abstract. This paper presents an approach to automatic annotation of learning objects'(LOs) content units that can be later assembled into new LOs personalized to the users' knowledge, preferences, and learning styles. Relying on a LO content structure ontology and some simple content-mining algorithms and heuristics, we manage to rather successfully determine the values of metadata elements aimed at annotating content units.

LOCO-Analyst is a learning analytics tool we developed to provide educators with feedback on students learning activities and performance. Evaluation of the first version of the tool led to the enhancement of the tool's data visualization, user interface, and supported feedback types. The second evaluation of the improved tool allowed us to see how the improvements affected the users' perceived value of the tool.

Social Networks (SN) emerged as a form of online communities during the outbreak of Social Web. Their purposes vary from maintaining professional contacts to having fun with friends, and their user-base continues to increase. The use of a SN represents a form of being present online (on an online service) and naturally incites users to leave some traces about the nature of their online presence.

Abstract. Software engineering education faces increasing pressure to provide students with those skills required to solve different kinds of software problems both, alone or as a member of a development team. Consequently, one of the main goals of software engineering curriculum is to teach students how to model, design and implement software, as well as how to exploit previous successful experiences and knowledge of others in solving similar problems.

Abstract Intelligent Learning Extended Organization (IntelLEO) is a new paradigm in learning communities. It represents a community that emerges as a temporal integration of two or more different business and educational communities and organizational cultures (industrial, research, and educational). The concept of IntelLEO is going to be investigated in a 3-year R&D project accepted for funding within the EU Seventh Framework Programme (FP7) and starting in early 2009.

Abstract Teaching and learning software design patterns (DPs) is not an easy task. Apart from learning individual DPs and the principle behind them, students should learn how to apply them in real-life situations. Therefore, to make the learning process of DPs effective, it is necessary to include a project component in which students, usually in small teams, develop a medium-sized software application.

ABSTRACT Self-regulated learning processes have a potential to enhance the motivation of knowledge workers to take part in learning and reflection about learning, and thus contribute to the resolution of an important research challenge in workplace learning. An equally important research challenge for successful completion of each step of a selfregulatory process is to enable learners to be aware of characteristics of their organizationally-embedded learning context.

CSCL (Computer Supported Collaborative Learning) is an interdisciplinary field that integrates researchers with different backgrounds, but one common goal: to support new learning experiences where students can interact mediated by technology and learn more effectively through exploration, discussion and self-regulation. Collaboration support is a complex issue due to the context of group learning where the synergy among learners' interactions affects learning processes and hence, the learning outcome.

The paper describes JessGUI, a graphical user interface developed on top of the Jess expert system shell. The central idea of the JessGUI project was to make building, revising, updating, and testing Jess-based expert systems easier, more flexible, and more user friendly. There are many other expert system building tools providing a rich and comfortable integrated development environment to expert system builders. However, they are all either commercial or proprietary products.

The paper describes JavaDON, an open-source expert systems shell based on the OBOA framework for developing intelligent systems. The central idea of the JavaDON project was to make an easy-to-use and easy-to-extend tool for building practical expert systems. Since JavaDON is rooted in a sound theoretical framework, it is well-suited for building even complex expert system applications, both stand-alone and Web-based ones.

Abstract The paper presents Abstract Compound Content Model (ACCM), a generic content model which we have devel-oped aiming to facilitate interoperability, repurposing and integration of diverse platform specific content models. Based on this model we have developed the ACCM ontology in order to turn the ACCM's elements (ie, content units and content aggregations) into resources that can be directly accessed and thus reused.
