The shape of online meetings

Live videoconferencing has become an integral part of international virtual learning and working with professionals, educators and students using online meetings to enhance their collaboration from different parts of the world. This paper explores the visualization of a set of different online meetings produced by the FlashMeeting' videoconferencing system. Our polar area visualization analysis reveals interesting patterns in participant dominance in online meetings: seminars, interviews, moderated project meetings, peer-to-peer meetings, web-casts and video lectures. Visualizing patterns in the use of foreground and background communication channels is a promising way to help us to start to explore individual user roles in different communities and in different meeting types

Collective Hermeneutics in a Systems Development Process

The inherent complexity of information systems development presents significant impediments to the achievement of shared meaning among the members of a development team. In addition to the technical requirements of systems development, its intensely social nature challenges project teams to unite around a collective understanding of the processes and objectives that they pursue. How then do software development teams resolve questions of shared meaning in the development process? In this study, we build upon observations of a large platform development team to identify the ways in which team members converge around shared meanings through a repertoire of interpretive techniques. Specifically, we develop a model of interpretive team interaction that is based on the concept of a collective hermeneutic process. The collective hermeneutic model extends the hermeneutic tradition in IS research by addressing the ways in which an interpretation takes shape not simply within the mind of an individual but also through collaboration with others. Finally, we discuss implications of this theoretical perspective for the design of systems development environments and the prospect for additional research on the interpretive processes of development teams

A tool for supporting the communication in distributed software development environment

In the Distributed Software Development (DSD) is fundamental the use of methodologies, techniques and tools to support the communication and help teams physically distributed in the activities accomplishment. The adequate communication in the cooperative work aids in the activities management, allows the identification of flaws and deviations in the planning accomplishment, it facilitates the conflicts solution, offers support to the decision making process and also contributes to maintain the cohesion of the team. This paper presents a tool that provides synchronous, explicit and formal communication, for a Distributed Software Development Environment. This tool, named VIMEE (Virtual Distributed Meeting), allows relate to CSCW (Computer Supported Cooperative Work) and DSD areas; it defines a common workspace to manage the virtual meeting, it supports the project management and the decision making in group.Facultad de Informátic

Expert Finding Using Social Networking

In today’s world, knowledge transfer is considered an important and essential activity for the success of an enterprise. Large corporations have realized the need to reuse existing knowledge rather than spend time and effort on solving the same problems again. For these reasons, most corporations now have knowledge repositories. These repositories are visited for possible solutions whenever there is a problem that cannot be easily resolved by using the expertise of the existing team. Apart from this, the problems faced by the people in the company can also be resolved by asking for help from expert in that problem domain. This approach proves to be more efficient in terms of time and manual efforts, while also saving resources. This report proposes a strategy of finding an expert in a required domain by analyzing a company’s social network i.e. communication amongst its employees. Efficiently finding an expert is one of the most important tasks currently faced by the information industry and this problem has not been sufficiently addressed in the past. Conducting further research in this field can improve the time required to solve critical time-sensitive problems in an enterprise environment, thereby improving the overall efficiency of the enterpris

Um modelo para gerenciar a comunicação em um ambiente distribuído de desenvolvimento de software

Entre equipes fisicamente distribuídas prover apoio a comunicação e a tomada de decisão em grupo é fundamental para que haja cooperação e coordenação nas tarefas que necessitam ser realizadas de forma colaborativa. Abordagens técnicas e comportamentais são essenciais para a definição dos requisitos necessários ao desenvolvimento de tecnologias que auxiliem equipes geograficamente distantes. Este artigo apresenta um modelo para gerenciar a comunicação em um ambiente distribuído de desenvolvimento de software. O modelo propõe a comunicação síncrona, explícita e formal e define uma área de trabalho comum para gerenciar reuniões permitindo que os usuários possam interagir e encontrar um consenso para assuntos relevantes ao gerenciamento de projetos. Apresenta principalmente duas grandes funcionalidades: apoio à comunicação e edição cooperativa. Para a elaboração do modelo foram abordados aspectos relevantes relativos a Gerenciamento de Comunicação, CSCW (Computer Supported Cooperative Work) e Desenvolvimento Distribuído de Software.Between physically distributed teams, provide support to the communication and the group decision making is basic to establish the cooperative and coordination to realize tasks that need to be carried in a collaborative way. Technical and behavior approaches are essential for the definition of the necessary requirements to the development of technologies that assist teams dispenses geographically. This article presents a proposal to manager the communication in distributed software development environment. The model proposes the synchronous, explicit and formal communication and defines an area of common work to manage meetings allowing that the users could interact and find a consensus for relevant subjects to the management of projects. It presents principally two great functions: support to the communication and cooperative edition.

Collaborative geographic visualization

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para a obtenção do grau de Mestre em Engenharia do Ambiente, perfil Gestão e Sistemas AmbientaisThe present document is a revision of essential references to take into account when developing ubiquitous Geographical Information Systems (GIS) with collaborative visualization purposes. Its chapters focus, respectively, on general principles of GIS, its multimedia components and ubiquitous practices; geo-referenced information visualization and its graphical components of virtual and augmented reality; collaborative environments, its technological requirements, architectural specificities, and models for collective information management; and some final considerations about the future and challenges of collaborative visualization of GIS in ubiquitous environment

Negotiation of software requirements in an asynchronous collaborative environment

The effect of task structure and negotiation sequence on collaborative software requirements negotiation is investigated. This work began with an extensive literature review that focused on current research in collaborative software engineering and, in particular, on the negotiation of software requirements and the requisite collaboration for the development of such requirements. A formal detailed experiment was then conducted to evaluate the effects of negotiation sequence and task structure in an asynchronous group meeting environment. The experiment tested the impact of these structures on groups negotiating the requirements for an emergency response information system. The results reported here show that these structures can have a positive impact on solution quality but a negative impact on process satisfaction, although following a negotiation sequence and task structure can help asynchronous groups come to agreement faster. Details of the experimental procedures, statistical analysis, and discussion of the results of the experiment are also presented, as are suggestions for improving this work and a plan for future research
