Service-oriented Context-aware Framework

Location- and context-aware services are emerging technologies in mobile and desktop environments, however, most of them are difficult to use and do not seem to be beneficial enough. Our research focuses on designing and creating a service-oriented framework that helps location- and context-aware, client-service type application development and use. Location information is combined with other contexts such as the users' history, preferences and disabilities. The framework also handles the spatial model of the environment (e.g. map of a room or a building) as a context. The framework is built on a semantic backend where the ontologies are represented using the OWL description language. The use of ontologies enables the framework to run inference tasks and to easily adapt to new context types. The framework contains a compatibility layer for positioning devices, which hides the technical differences of positioning technologies and enables the combination of location data of various sources

Evaluating Students' Perception of a Three-Dimensional Virtual World Learning Environment

Three-dimensional virtual environments have gained wide popularity due to improvement in graphic rendering technology and networking infrastructure. Many education institutions have been trying to leverage the potential of 3D virtual environments in their application in education. In this research, we aim to evaluate the students’ perception of virtual environments in teaching and learning activities. We set up a virtual classroom, where a short presentation was delivered to students through virtual projectors in Second Life, the most widely adopted 3D virtual environment. The students filled in a questionnaire after the class. We found that the students gave a statistically higher evaluation to 3D virtual environments in terms of satisfaction and enjoyment, while comparable scores between 3D and traditional learning environment in terms of concentration, perceived usefulness, and learning and understanding were obtained. Our results show that virtual learning environment is of great potential in e-learning. Some recommendations in using the virtual environment for learning activities are given.published_or_final_versio

Peripatetic electronic teachers in higher education

This paper explores the idea of information and communications technology providing a medium enabling higher education teachers to act as freelance agents. The notion of a ‘Peripatetic Electronic Teacher’ (PET) is introduced to encapsulate this idea. PETs would exist as multiple telepresences (pedagogical, professional, managerial and commercial) in PET‐worlds; global networked environments which support advanced multimedia features. The central defining rationale of a pedagogical presence is described in detail and some implications for the adoption of the PET‐world paradigm are discussed. The ideas described in this paper were developed by the author during a recently completed Short‐Term British Telecom Research Fellowship, based at the BT Adastral Park

FGPE+: the mobile FGPE environment and the Pareto-optimized gamified programming exercise selection model - an empirical evaluation

This paper is poised to inform educators, policy makers and software developers about the untapped potential of PWAs in creating engaging, effective, and personalized learning experiences in the field of programming education. We aim to address a significant gap in the current understanding of the potential advantages and underutilisation of Progressive Web Applications (PWAs) within the education sector, specifically for programming education. Despite the evident lack of recognition of PWAs in this arena, we present an innovative approach through the Framework for Gamification in Programming Education (FGPE). This framework takes advantage of the ubiquity and ease of use of PWAs, integrating it with a Pareto optimized gamified programming exercise selection model ensuring personalized adaptive learning experiences by dynamically adjusting the complexity, content, and feedback of gamified exercises in response to the learners’ ongoing progress and performance. This study examines the mobile user experience of the FGPE PLE in different countries, namely Poland and Lithuania, providing novel insights into its applicability and efficiency. Our results demonstrate that combining advanced adaptive algorithms with the convenience of mobile technology has the potential to revolutionize programming education. The FGPE+ course group outperformed the Moodle group in terms of the average perceived knowledge (M = 4.11, SD = 0.51).info:eu-repo/semantics/publishedVersio

The seamless integration of Web3D technologies with university curricula to engage the changing student cohort

The increasing tendency of many university students to study at least some courses at a distance limits their opportunities for the interactions fundamental to learning. Online learning can assist but relies heavily on text, which is limiting for some students. The popularity of computer games, especially among the younger students, and the emergence of networked games and game-like virtual worlds offers opportunities for enhanced interaction in educational applications. For virtual worlds to be widely adopted in higher education it is desirable to have approaches to design and development that are responsive to needs and limited in their resource requirements. Ideally it should be possible for academics without technical expertise to adapt virtual worlds to support their teaching needs. This project identified Web3D, a technology that is based on the X3D standards and which presents 3D virtual worlds within common web browsers, as an approach worth exploring for educational application. The broad goals of the project were to produce exemplars of Web3D for educational use, together with development tools and associated resources to support non-technical academic adopters, and to promote an Australian community of practice to support broader adoption of Web3D in education. During the first year of the project exemplar applications were developed and tested. The Web3D technology was found to be still in a relatively early stage of development in which the application of standards did not ensure reliable operation in different environments. Moreover, ab initio development of virtual worlds and associated tools proved to be more demanding of resources than anticipated and was judged unlikely in the near future to result in systems that non-technical academics could use with confidence. In the second year the emphasis moved to assisting academics to plan and implement teaching in existing virtual worlds that provided relatively easy to use tools for customizing an environment. A project officer worked with participating academics to support the teaching of significant elements of courses within Second LifeTM. This approach was more successful in producing examples of good practice that could be shared with and emulated by other academics. Trials were also conducted with ExitRealityTM, a new Australian technology that presents virtual worlds in a web browser. Critical factors in the success of the project included providing secure access to networked computers with the necessary capability; negotiating the complexity of working across education, design of virtual worlds, and technical requirements; and supporting participants with professional development in the technology and appropriate pedagogy for the new environments. Major challenges encountered included working with experimental technologies that are evolving rapidly and deploying new networked applications on secure university networks. The project has prepared the way for future expansion in the use of virtual worlds for teaching at USQ and has contributed to the emergence of a national network of tertiary educators interested in the educational applications of virtual worlds

THE USE OF RECOMMENDER SYSTEMS IN WEB APPLICATIONS – THE TROI CASE

Avoiding digital marketing, surveys, reviews and online users behavior approaches on digital age are the key elements for a powerful businesses to fail, there are some systems that should preceded some artificial intelligence techniques. In this direction, the use of data mining for recommending relevant items as a new state of the art technique is increasing user satisfaction as well as the business revenues. And other related information gathering approaches in order to our systems thing and acts like humans. To do so there is a Recommender System that will be elaborated in this thesis. How people interact, how to calculate accurately and identify what people like or dislike based on their online previous behaviors. The thesis includes also the methodologies recommender system uses, how math equations helps Recommender Systems to calculate user’s behavior and similarities. The filters are important on Recommender System, explaining if similar users like the same product or item, which is the probability of neighbor user to like also. Here comes collaborative filters, neighborhood filters, hybrid recommender system with the use of various algorithms the Recommender Systems has the ability to predict whether a particular user would prefer an item or not, based on the user’s profile and their activities. The use of Recommender Systems are beneficial to both service providers and users. Thesis cover also the strength and weaknesses of Recommender Systems and how involving Ontology can improve it. Ontology-based methods can be used to reduce problems that content-based recommender systems are known to suffer from. Based on Kosovar’s GDP and youngsters job perspectives are desirable for improvements, the demand is greater than the offer. I thought of building an intelligence system that will be making easier for Kosovars to find the appropriate job that suits their profile, skills, knowledge, character and locations. And that system is called TROI Search engine that indexes and merge all local operating job seeking websites in one platform with intelligence features. Thesis will present the design, implementation, testing and evaluation of a TROI search engine. Testing is done by getting user experiments while using running environment of TROI search engine. Results show that the functionality of the recommender system is satisfactory and helpful
