Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Systems design is complex to begin with but even more so when requirements of ‘sustainable design’ are added. This notion is of particular relevant to communities interested in building systems that contribute to greening the planet, i.e., with environmental sustainability of technology-based systems. The solution potential of such ‘sustainability systems’ is immense but impact to date is sparse....
Science fiction had anticipated the prediction of future occurrence of crimes. In fact, that prediction is actually possible. It can be done with some imprecision and by computer algorithms using available data from various sources. The prediction involves approximate time and risk maps of occurrence of certain type of felonies such as home burglaries, armed robberies and violent thefts. The police...
Nowadays, collaborative editing systems, such Google Docs, Microsoft Office Web Apps, and Codox Wave Apps (for supporting read-time editing in existing Web browser-based editors, including Gmail, Wikipedia, Evernote, and WordPress), are commonly used by hundreds of millions of people around the world. Research on collaborative editing, however, started in the 1980s as a niche area in the field of...
The advance of technology has influenced the relationship between government and citizen. In this scenario, the convergence between digital democracy, crowd computing, information visualization, mining of social media and collaborative information systems can increase citizen participation in solution for social problems. The aim of this paper is to propose an application that provides a collaborative...
Internet access has become a requirement to participate in society; however, the majority of the world's population is not yet online. Citizens can self-organize cooperatively to crowdsource community network infrastructures and achieve Internet access. In order to help address that challenge, this paper provides an analysis of a crowdsourced Internet access mechanism: the distributed Web proxy service...
In this paper, we designed and implemented a lightweight mobile crowdsourcing platform called WeCrowd. What makes it distinct from other mobile crowdsourcing applications is that, it is based on WeChat and enables users to post and work on crowdsourcing tasks without setup process, which can greatly save storage space, speed up crowd work and also be convenient for users to take part in tasks. Based...
It is understood that large quantities and diversity among users of a crowdsourcing system is something to be explored. So that the characterization of these users can aid in the decision-making on aspects related to crowdsourcing systems design, such as user interface design, recruitment strategies, motivating participants, among other specific challenges of crowdsourcing systems. Considering the...
Knowing the future of work is something that we all wish to do in order to be prepared for it. Unfortunately, humans cannot predict precisely the future of anything yet. Nevertheless, in this paper we try to get as close as we can to it by looking at some trends of the future of work. This challenge is undertaken by reviewing the scientific literature on the subject. We elaborate on some insights...
Expertise transfer is a complex, however fundamental process in organizations. To save money and mitigate expertise loss risk, organizations are investigating not only expertise transfer techniques, but also how to accelerate expertise. Our hypothesis is that split expertise from an individual to transfer to a collaborative team constitute a viable and effective accelerated expertise technique. Beyond...
Based on dynamic research perspectives of time slicing, this paper shows an endeavor on mining dynamic features of the scientific teams. Traditionally the static method of network structure analysis can successfully be used to analyze the distribution of network resource structure. But it cannot be used to explore the dynamic features of research groups, because of its lacks on the influence of some...
A study was carried out to compare an integrated HTML5-based real-time video conferencing solution against a separately installed video conferencing solution in the same web-based meeting support application. To carry out this comparison, WebRTC and Skype have been integrated into an existing groupware application. Our study shows that comparing to a separately installed, best of breed video conferencing...
Organisations now frequently rely on virtual collaboration through the use of computer technology. After a sequence of meetings, participants may only need to refer to the most important points rather than the whole meeting proceedings. This paper addresses the need for automated meeting summarisation in virtual meeting systems. An extraction approach to summarisation is adopted and a new algorithm...
High performing teams may benefit the execution efficiency of business processes. In executing a process, the performance of the team is concerned with the individual expertise of team members and the handover relations between executors of adjacent tasks of the process. Team formation problem in the presence of business process can be defined as finding a group of individuals to execute all tasks...
The wide application of Business Process Management has led to the existence of a tremendous amount of process models. Similarity measurement of process models is usually considered a versatile solution to fulfill their effective utilization. Although many researches haves worked on different notions of model similarity, most of them are not precise enough, as there is always a gap between the structural...
