Conventional online social networks (OSNs) are implemented in a centralized manner. Although centralization is a convenient way for implementing OSNs, it has several well known drawbacks. Chief among them are the risks they pose to the security and privacy of the information maintained by the OSN; and the loss of control over the information contributed by individual members.
The abundance of educational resources available on the Web leads to information overload for the students and the difficulty in finding useful and relevant resources for a specific learning context. The solution that we propose in this paper is a platform called Edu3R (Educational Resources Retrieval and Recommendation), which relies on community filtering: students enrolled in the same course can...
The business analyst role was established in response to concerns about a 'gap' between technical IT staff and users. Such a 'gap' has been implicated in the failure of information systems to consistently deliver business value. However research suggests that while business analysts may facilitate the relationship between technical staff and business users, boundaries may still occur between business...
The provision of pervasive computing services is a challenging research area. This paper elaborates on the notion of Personal Smart Spaces (PSSs) that allows the delivery of pervasive services to mobile users. PSSs aim to couple the facilities offered by next generation mobile communications with the features provided by the static smart spaces to support a more ubiquitous, context-aware and personalised...
This paper introduces a method for head expert identification in a social network based on local community detection and formal concept analysis. There are several methods for expert identification, but most of these methods try to find an expert for a particular area. In this paper, we propose a novel approach to identify a head expert. This person is in the background and most of the time he is...
Code reviews are an integral part of the development of a dependable system such as for airport operations. It is commonly accepted that code reviews are an effective quality assurance technique even if a rigorous application is also a high cost factor. For large software systems a formal method may be inapplicable throughout the whole code base. In this study an airport operational database (AODB)...
This study describes an approach to track groups over time as they participate in larger networks of groups. Groups were tracked in a Massive Multi-Player Online Role Playing Game (MMORPG), a context typical of many online venues and similar to some situations in the real world. Based on social scientific theories the study identified possible avenues to detect groups, explored game logs to identify...
This paper proposes a concept of providing a theme tour in which people can deeply experience heritage in a main topic using handheld devices. Based on the concept, a Demodulating and Encoding Heritage (DEH) heritage exploring system is developed using a Location Based Service (LBS) mechanism. In order to fulfill the LBS-based heritage touring experience, a metadata element set has been defined to...
Action Science Explorer (ASE) is a tool designed to support users in rapidly generating readily consumable summaries of academic literature. It uses citation network visualization, ranking and filtering papers by network statistics, and automatic clustering and summarization techniques. We describe how early formative evaluations of ASE led to a mature system evaluation, consisting of an in-depth...
Interactive web-based resources are significant to the mediation of culture in that they act as an interface (Newton: 2003) between communities and information structures. The focus of this paper is on the use of digital media arts and user-centered technologies to develop a digital heritage resource to revitalize a community's cultural capital. The paper addresses the creation and use of an interactive...
A lot of content for tele-lecturing portals was produced in the last decade. But metadata to filter the content was not generated adequately. It therefore takes a long time for users to filter through all the videos available until they find the learning content they are looking for. That is why it is a new challenge to find solutions how to filter the large amount of data with a small base of metadata...
Current learning systems are frequently criticized for their predominant focus on explicit, and in particular, written representation of knowledge. There are communities around the world where verbal knowledge is more pervasive than written knowledge. This paper presents a study of how such knowledge can be accessed anywhere/anytime, in a form that may be used and understood in a standardized format,...
Automatic face annotation (or tagging) facilitates improved retrieval and organization of personal photos in online social networks. In this paper, we present a new collaborative face recognition (FR) method that aims to improve face annotation accuracy. The proposed method makes efficient use of multiple FR engines and databases that are distributed over an online social network. The performance...
In this work we present "AlertMe", a semantics-based, context-aware notification system that provides personalized alerts to graduate students based on their preferences. An extensive description of the system is carried out. We present the underlying ontology that models the available knowledge, as well as how higher level knowledge inference and context-based decision making is achieved...
For the last decade, the areas of e-business and e-service have expanded rapidly. Service oriented architecture (SOA) is introduced to create and execute business process on the Web. In SOA, the importance of managing the reputation ofservices has emerged. Thus, there has been much research to evaluate and manage the reputation of services. This paper proposes the context-aware distributed reputation...
