Kolline: a task-oriented system for collaborative information seeking

This paper presents results of an exploratory study which observed Linux novice users performing complex technical tasks using Googles search engine. In this study we observed that information triage is a difficult process for unexperienced users unless well structured information is provided which results in better satisfaction and search effectiveness. Providing a well structured information allows users to browse through different pieces of documentation without depending exclusively on the keyword search. Based on these observations, this research prototyped Kolline, a system that aims to facilitate information seeking for unexperienced users by allowing more experienced users to collaborate together. Users in Kolline create a task-oriented navigation structure based on web annotations. In this paper we discuss the potential benefits of this technique on helping unexperienced users to solve complex search tasks and present improvements for future work.

A service-oriented framework to promote interoperability among DRM systems

Through the past years, several digital rights management (DRM) solutions for controlled dissemination of digital information have been developed using cryptography and other technologies. Within so many different solutions, however, interoperability problems arise, which increase the interest on integrated design and management of these technologies. Pursuing these goals, this paper presents a framework which aims at promoting interoperability among DRM systems, using a service-oriented architecture (SOA) and a high-level policy modeling approach.

A Policy-Based Framework for Interoperable Digital Content Management

Going Beyond The Challenge!: Investigating The Aspects That Attract People to Participate in Hackathons

Hackathons are events where their participants face the challenge of working intensively and collaboratively with other people. In these events, the participants have the opportunity to develop functional prototypes and solutions to real problems in a short time period (one to three days). Those kind of events have become increasingly popular and spread to several fields of knowledge. Also, they have been adopted by many organizations over the world. However, there is little scientific data that explains why people have participated in hackathons. In this paper, we report findings from an exploratory study in two hackathons organized by a big IT company. We aim to understand why their participants have voluntarily participated in such events. We identified four sets of motivational factors: technical, social, individual and business motivations. Technical motivations are associated with skill acquisition, while social motivations are related to the interaction between people during the event. Also, individual motivations are associated with a sense of autonomy and enjoyment of work. Finally, business motivations include the opportunity of publicizing work and the possibility of establishing partnerships. Our findings contributes to a broader understanding of the motivations for participating in hackathons, as well as providing recommendations for the organization of such events.
