When teaching software engineering courses it is highly important to have good text books that are well-founded, up-to-date, and easily accessible to students. However, currently available text books on the market are either very broad or highly specialized, making it hard to select appropriate books for specific software engineering courses. Moreover, due to the rapidly changing subject of software...
The use of Web 2.0 technologies is increasingly common in many aspects of life: social, work, and study. The study reported here looks into how one type of Web 2.0 tool, the wiki, was being used to support groups of IT students involved in a collaborative authentic-task in their undergraduate studies to develop a software solution required by their "clients". The study indicates the existence...
Agile software development processes are widely adopted in software engineering projects. Their low organizational overhead and iterative nature make them ideal choices for small development teams. The application of those methods in software projects that require collaboration between multiple sub-teams is a challenging task that remains subject to intensive research. Especially the initial phases...
Virtual enterprise (VE) is such an effective and collaborative way for today's enterprise to jointly face the great pressures from quickly growing globalization and world-wide market competition. In order for enterprises to quickly form a VE and perfectly achieve interactions among the VE's members, a conceptual model based-on enterprise core capability and an agent-based architecture are proposed...
E-learning technologies such as Web-CT, Blackboard, Moodle and Sakai are the common learning management systems used in teaching these days. Using technology to support group work is a more recent practice than using it for teaching material delivery. Research in preparing students to use technology for online group work especially in distance education is limited. This research is a case study that...
We propose a framework for discovery of collaborative community structure in Wiki-based knowledge repositories based on raw-content generation analysis. We leverage topic modelling in order to capture agreement and opposition of contributors and analyze these multi-modal relations to map communities in the contributor base. The key steps of our approach include (i) modeling of pair wise variable-strength...
Wiki is a collaborative tool for designing web communications allowing users to edit, add or revise content through a web browser. Despite of various benefits offered by the wikis use, there is no guarantee of a good structure of its content. This occurs especially by the difficulty to graphically visualize the information architecture. In this paper is proposed a Model-Driven Development (MDD) approach...
This article presents the method Cyclus to collaboration process improvement, based on collaborative filtering and Action Research, and the Modus system, developed to support Cyclus applying. The method was developed along 2 years of research and was evaluated 2 times: in a pilot case study, and in an explanatory case study. This article communicates the results of the second study, the explanatory...
Most recently, the use of collaboration element within information behavior research namely Collaborative Information Behavior (CIB) has been increasing. In addition, the success of wiki-based, large-scale, open collaborative content creation systems such as Wikipedia has aroused increasing interests of studies on their collaborative model. In contrast to previous related work, this paper focuses...
This paper describes an approach to evaluating teams of contributors in Wikipedia based on social network analysis. We present the idea of creating an implicit social network based on characteristics of pages' edit history and collaboration between contributors. This network consists of four dimensions: trust, distrust, acquaintance and knowledge. Trust and distrust are based on content modifications...
The digital age has brought about new platforms for collaboration which have provided interesting and effective ways of enabling people to engage in a wide variety of socially-driven activities. One only needs to observe the many free/libre open source software projects on the web, where millions of connected individuals actively participate in the development and deployment of a wide range of software...
Software development is fundamentally a collaborative task. Developers, sometimes geographically distributed, collectively work on different parts of a project. The challenge of ensuring that their contributions consistently build on one another is a major concern for collaborative development and implies concerns with effective communication, task administration and exchange of documents and information...
A pilot web application for collaborative georeferencing of Slovenian works of literature was developed. Problems in georeferencing in general and georeferencing works of literature are discussed. The pilot system can be a model for establishing web sites for georeferencing literature for different languages. The application is based on Google Maps and implemented using PHP, JavaScript and MySQL....
Adaptive Educational Hypermedia systems (AEH) enhance learning by adaptation and personalisation. As a consequence, wide ranging knowledge and learning content are needed. Problems then emerge in the provision of suitable authoring tools to carry out the authoring process which is complex and time consuming. Based on the fact that former research studies on authoring have identified drawbacks in collaboration,...
Wikis, best represented by the popular and highly successful Wikipedia system, have established themselves as important components of a collaboration infrastructure. We suggest that the complex network of user-contributors in volunteer-contributed wikis constitutes a digital ecosystem that bears all the characteristics typical of such systems. This paper presents an analysis supporting this notion...
Tagging is one of the most popular services in Web 2.0 and folksonomy is a representation of collaborative tagging. Tag cloud has been the one and only visualization of the folksonomy. The tag cloud, however, provides no information about the relations between tags. In this paper, targeting del.icio.us tag data, we propose a technique, FolksoViz, for automatically deriving semantic relations between...
Information systems are subject to a perpetual evolution, which is particularly pressing in Web information systems, due to their distributed and often collaborative nature. Such continuous adaptation process, comes with a very high cost, because of the intrinsic complexity of the task and the serious ramifications of such changes upon database-centric information system softwares. Therefore, there...
Our research question concerns the usefulness of wikis in corporate settings. The answer to this question is not clear. On one hand, business firms are aware of the impact wikis have had on the Internet, and perceive wikis as an up-and-coming technology for supporting collaborative work. On the other hand, the fundamental principles underlying wikis - openness, non-attribution, egalitarianism, and...
This paper explores the design and evaluation of a trust model to establish trust management in an open source collaborative information repository for an emergency response environment. The proposed model is an instantiation of the SECURE framework and it is based on the characteristics of trust defined by recent information systems research. Evaluation of the model is based on a case study of a...
According to Tim Berners-Lee, wiki technology represents an instantiation of how the World Wide Web was planned to work: a platform that users can use both to retrieve content (read) and contribute content (write). Wiki technology lends itself to many uses. One of the main features of wiki technology is its support for collaborative editing of content. In this paper, we introduce briefly wiki technology,...
