a model for semantic ties

We are relying on Twitter as one of the most used service for sharing links and news with colleagues and friends. Twitter is thus a good example for the power of the Artefact-Actor-Network model. In my personal blog I published the following article that is also interesting for this audience: With the recent announcement from Twitter to allow arbitrary metadata attached to each tweet (so-called annotations), the Twitter platform is getting even more interesting for tool developers. ReadWriteWeb writes: With annotations, third-party Twitter developers can add any additional metadata to a Twitter post. [...] And a tweet can have more than one annotation attached to it. This extra data will initially start off small - Twitter developer Marcel Molina said it will "probably" be around 512 bytes. But over time, it will gradually grow larger as Twitter rolls out the feature and ...

In the coming months we will apply Artefact-Actor-Networks to several scientific conferences in order to enhance the attendees' awareness of what is going on at the conference. These small-scale studies are being carried out under the umbrella of the STELLAR network of excellence. For doing so we will ask attendees of scientific conferences (e.g. EC-TEL 2010 and ED-MEDIA 2010) to submit some of their online handles during the registration process. The organizers of the conferences will then send those online handles to our team so we can feed the AANalyzer application with the data. All data submitted will be exclusively used for the purpose of analyzing the structure and dynamics of a scientific community. Furthermore we will give all conference attendees access to the AANalyzer tool. For now we are asking conference attendees for the following online handles: Twitter account Delicious account Slideshare account LinkedIn account Facebook account URL of ...

Happy New Year. Happy Easter. It's already spring. Well, it took me some time to finish with this blog entry but as you may have noticed via Twitter or my personal blog, there is pretty much going on with Artefact-Actor-Networks right now. After we presented the AAN model at the CollaborateCom 2009 in Washington, our first implementation of the AAN backend was extended, so we're now able to analyse Twitter and Wikipedia. Furthermore we're working on the integration of Delicious, Slideshare and Scribd. Moreover, we're developing a rating scheme for social media tools in order to find out how well they'd fit into the AAN backend. Regarding the similarity of artefacts, actors and groups we spent many hours of finding the right algorithm and storage mechanism for doing so and found out that it will take tons of storage space and ...

At CollaborateCom 2009 in Washington D.C. I gave a talk about Artefact-Actor-Networks and introduced the model to experts in the field of collaboration and cooperation in networks. I received very good feedback regarding the semantic relations that can be applied and some additional vocabularities to use. Furthermore there were poeple that saw other concrete usage scenarios for AANs (e.g. Pedestrian Social Networks) that I'd never thought of. Here are the slides from the talk. If you have any questions or comments, just let me know. Artefact-Actor-Networks as tie between social networks and artefact networks View more documents from Wolfgang Reinhardt.

Our paper about Artefact-Actor-Networks has been accepted at the CollaborateCom 2009 in Washington D.C. in november.Matthias and I will go there and introduce the idea to a wider public and ask for feedback for our concepts. I presented some rough sketches about AAN at the ICL 2009 and EC-TEL 2009 conferences and the possibilities to visualize dynamics in communication and collaboration and received very possitive feedback and requests for integration in some projects.

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. AANs are meant to extend social networks through a layered approach of data storage and the linkage to so called artefact networks. Artefact networks basically represent bits of data from different data sources with some semantical links between them. We hypothesize that we can use the same metrics from social network analysis in artefact networks. In Artefact-Actor-Networks we take a closer look at the multiple levels where communication and collaboration takes place in technology ...
