Abstract:

The use of microblogging applications (especially Twitter) is becoming increasingly commonplace in a variety of settings. Today, active conference participants can post messages on microblogging platforms to exchange information quickly and in real-time. Recent research work was based on quantitative analyses in terms of the number of tweets or active Twitter users within a specific time period. In this paper, we examine the content of the contributions and aim to analyze how useful posts are for the “listening” Internet auditorium. It can be shown that only a few microblogs are of interest for non-participants of the specific event and that meaningful usage of a microblogging application requires greater care than previously anticipated.

Getting Granular on Twitter: Tweets from a Conference and their Limited Usefulness for Non-Participants

Wissensarbeit zeichnet sich dadurch aus, dass sie größtenteils aus der Nutzung, Verwaltung und Erzeugung von Information besteht. Die Studie beschäftigt sich mit Wissensarbeitern, den Rollen die sie während der regelmäßigen Arbeit einnehmen und den Aktivitäten die sie zur Durchführung Ihrer Arbeit ausführen. Weiterhin wird versucht typische Tätigkeiten in der Wissensarbeit mit Applikationen zu verknüpfen.

Wir freuen uns über Eure Teilnahme an der Studie, die auf deutsch und englisch verfügbar ist. Insbesondere wollen wir Euch bitten, diesen Aufruf in Euren Communities zu verteilen. Die Umfrage ist selbstverständlich anonym.

In the focus of the study are knowledge workers, the multiple roles they take on during their regular work and the actions they perform during accomplishing their work. A knowledge worker is anyone who develops or uses knowledge in his or her daily working tasks. Furthermore we try to associate application types with the knowledge actions.

We would like to ask you for your participation in the study which will take approximately 25 minutes. Your participation is anonymous and all answers will be treated confidentially.

You can access the survey at http://bit.ly/KWRStudy

Please feel free to forward the link to the survey to your colleagues, retweet or blog about this call for participation.I count on the power of my social network…

We will keep you updated about the results of the study.

Social networks reflect communication, cooperation and loose acquaintances in networked communities. Numerous metrics allow to expose connections, important persons or clusters within these communities. Furthermore, networks can be spanned to connect documents, blog entries or wiki articles. We call such a network an artefact network. In this paper we introduce the approach of Artefact-Actor-Networks that tries to connect social networks and artefact networks in order to make claims on the semantical connections between persons and manifold artefacts. We present practical use cases for Artefact- Actor-Networks and discuss generic and specific semantical requirements and added values through the existence of Artefact-Actor-Networks.

Curious about what’s an AAN?

Artefact-Actor-Networks (AANs) are a theoretical model to link social networks and artefact network in order to make claims about the semantic relatedness between users and their respective artefacts. The general goal of AANs is to ease the understanding of how these to knowledge entities (Trier, 2005) are interconnected, how they influence each other and how we can make use of semantic technologies in this field of research

I missed the morning session of the TEL-CoPs workshop but the afternoon session was very interesting and Manolis Tzagarakis gave a really interesting talk about “Practical Lessons Learned while Developing Web 2.0 Collaboration Services for Communities of Practice“. One of the major findings was that you have to develop the UI at first and test this with your users and afterwards focus on the architecture. As we are computer scientists, we tend to do it the other way around. The other thing he pointed out is that the later you introduce features to a tool, the more unlikely it is to be used. There I presented my second paper about how to support CoPs with Twitter. I received mostly positive feedback back there was a heavy discussion about the way we visualize things. I take this critics and will improve future visualizations using visual analytics methods.

Abstract:

Classical tools for supporting software engineering teams (collaborative development environment, CDE) are designed to support one team during the development of a product. Often the required data sources or experts reside outside of the internal project team and thus not provided by these CDEs. This paper describes an approach for a community-embedded CDE (CCDE), which is capable of handling multiple projects of several organizations, providing inter-project knowledge sharing and developer awareness. The presented approach uses the mashup pattern to integrate multiple data sources in order to provide software teams with an exactingly development environment.
