is it just me

After all the buzz around Foursquare, Facebook Places and Co. and my (initially) rather restraining attitude towards such services, I will try Foursquare for a week starting today. In the context of my Ph.d. thesis I am thinking about how such location-awaren systems could be used to enhance researchers awareness and I need to figure out how the systems work. So I will probably spam you (my Twitter followers and Facebook friends) with some check-in stuff. I hope you understand it’s on her majesty’s service for advances in sciences

Btw: You can see my check-ins at Foursquare

Today we had the final presentations of our Future Social Learning Networks (FSLN) seminar. The seminar took place at the University of Paderborn and the University of Augburg (both in Germany). I have to say that I supervised a number of seminars during my time at the University of Paderborn, but what I experienced today was awesome. I supervised the seminar together with my colleague Nina Heinze, who also works at the KMRC in Tübingen.

The seminar was designed to let students experience the power of Social Media in real-life situations, so we decided to have them cooperating with a fellow student from another university in another city, far away from home. So they HAD to use tools for keeping in sync with their partner, to communicate, coordinate and cooperate (you remember the classification of groupware from Teufel et al.?). So we introduced social media tools in higher education to them (thanks again to Cristina Costa for doing the lovely voicethread) and the students started to test Twitter, Delicious, Mendeley, SlideShare, FlashMeeting and Co for their work. We told them that we’d expect a collaborative presentation, a final report and an computer science artifact that represents what they did. After the first week we scheduled team meeting with the student groups where they presented their first ideas on the focus of their work and how the could design or implement the required artifact. The same thing took place 3 weeks later where we focused the topic even further and decided what artifact should be created. Nina and me were surprised by both the creativity, engagement and quality of the results in such an early phase of the seminar – because we knew different from former seminars. During the following weeks, we had two FlashMeetings with the whole group and some individual talks on Skype and gave little advice where help was needed. We could follow the students’ work from their bookmarks on Delicious and the shared articles in Mendeley (thank you guys for the extended shared collection, you really rock), could follow Tweets and had short ad-hoc face-to-face meetings at the coffee machine. All in all a pretty satisfying work load during the semester with pretty motivated students.

Today we had the final presentations; the students in Paderborn were sitting in a room in Paderborn, the students in Augsburg were in Augsburg. We used uStream.tv to stream the presentations from one city to another and Skype desktop sharing to transfer sound and the slides to both places simultaneously. Furthermore we had a Twitter backchannel and my boss was attending from another location via Skype as well. I thought: what a mess, technology will never do this. BUT IT DID. And it did perfectly. Yeehaw. You can see a picture of the Paderbornian setting here:

But then the students started to present their work. All in all we had the following topics:

1. Real-time collaborative learning
2. Media disruptions in Web 2.0 environments
3. Awareness in Learning Networks
4. Interactive Learning Ressources
5. Social Network Analysis in Artefact-Actor-Networks
6. Game-based Learning
7. University 2.0

Our students not only invested a lot of time in their presentations and the writing of well-formulated and substantiated articles, they also presented stunning prototypical implementations and architectural design for IT systems that would really make a difference (see the pictures on Flickr). One team was developing a MashUp real-time collaborative learning environment that combined a whiteboard with video chat, twitter integration and the ability to load any RSS feed. The widget-based environment was running on Django in Python (a language we do not teach in Paderborn) and allows for the creation and storage of differing MashUps that can be used, shared, stored and re-accessed later. Another team analyzed the daily routines of students in Paderborn and Augsburg and modeled the study-related part in EPK models (something we never thought of). The team identified a range of media disruptions during the exam application for example (12 disruption in Paderborn, with 4 different tools involved). Finally, the did paper prototyping for an improved system that could be used at various universities and developed an infrastructure design. Another team was developing an interactive PDF where Flash content from nearly all social media platforms can be integrated. They showed a PDF that incorporated fully functioning SlideShare presentations and YouTube videos, the above-mentioned VoiceThread and even FlashMeeting replays from our meetings. Moreover, they developed an application CommentInAPDF that allows to send tweets from within a PDF (there even was an extended version where they automatically added an a priori defined hashtag to the tweet). The presentation of the PDF was so impressing and opened up so many visions of what to do with such technical options, I’m still stunned. Here is a video of their presentation (in German).

Finally the University 2.0 group did an online survey among 470 German-speaking students regarding their vision of the University in the year 2030 and combined those findings with qualitative interviews with scientific staff. Furthermore they likened their findings with future predictions (e.g. The Horizon Reports) and produced this awesome Prezi presentation.

I have to say that I never had so motivated students, which invested their valuable time and lifeblood into a seminar and produced so cool artifacts. During the feedback session they told us, that the collaboration with others that they couldn’t talk to other than mediated to social software was very motivating for them and that they learned to love the tools we introduced to them. Also they mentioned that the permanent availability of the supervisors via social media tools gave them the feeling safety and encouraged them to ask for help and council.

Students, that was rocket science, thank you so much. I hope to work with you again soon!

After the successful Science 2.0 workshop at last year’s EC-TEL conference, there will be another cool workshop where you can present your cool ideas and applications about what Science 2.0 and Research 2.0 could look like. Spread the word and hand in your stuff. We’re pretty much looking forward to see what you are doing…

Research2.0 is in essence a Web2.0 approach to how we do research. Research2.0 creates conversations between researchers, enables them to discuss their findings and connects them with others. Thus, Research2.0 can accelerate the diffusion of knowledge.

Topics for this workshop include, but are not limited to:

• Evaluation of existing Research2.0 tools and infrastructures from a TEL perspective
• Development of TEL-related use case scenarios for Research2.0 tools and infrastructures
• Influence of Research2.0 tools and technologies on scientific practices in TEL
• Formats and protocols for Research2.0 data exchange (linked data, RSS, BuRST, …)
• Ownership and privacy of research information
• Practices of the diverse Technology Enhanced Learning disciplines, and how Research2.0 can influence them

Format

Authors are invited to submit original unpublished work. The following types of contributions are possible:

• Short papers (3-5 pages) that state the position of the authors on issues relevant to the workshop or work in progress, even when in very early state.
• Full papers: (8-12 pages) that describe problems, needs, novel approaches and frameworks within the scope of the workshop. In this category, empirical evaluation papers and industrial experience reports are welcome for submission.

Each presenter will be linked to related papers from other presenters and will be asked to compare in the presentation how the works of others relates to their own work.

The presentation of unfinished ideas, tools under development and especially failures is explicitly encouraged. This includes the presentation and discussion of tools and their real-world usability.

Prior to the workshop, a dedicated group on TEL Europe will be opened to:

• facilitate discussions among participants before and after the conference;
• post submitted papers for an open peer review;
• publish information and news about the workshop;
• collect reactions through social media on the workshop.

All presentations and discussions will be broadcast via Flashmeeting to attract more feedback, and to document the event. Online questions and comments will be explicitly taken into account during the workshop.

Important Dates

• Paper submission: 27 June 2010
• Paper acceptance: 11 July 2010
• Main Conference: 28 September-1 October 2010

Paper submission and questions

Please submit your paper at http://www.easychair.org/conferences/?conf=research20.

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 scales up in order to support it. The company hopes to have it end up “around 2K,” says Molina. How developers use that extra space is entirely up to them – there can be one giant piece of extra data attached to a tweet or a thousand tiny ones.

In a blog post Raffi Krikorian posted a useful map of the topography of a tweet. The picture could serve as cheat sheet for any developer dealing with Twitter… See also Raffi’s first ideas on what to do with annotations:

Next week I’ll be in Innsbruck at Grillhof for the JTEL WinterSchool 2010. Luckily I received a funding of the STELLAR Network of Excellence (thx for that) and can enjoy the exchange of ideas with a lot of like-minded Ph.D. students and the crème de la crème of the TEL researchers.

One of our preparation tasks was to prepare a mini Pecha Kucha talk consisting of 6 slides where each of the slides is shown exactly 30 seconds – no matter if you finished what you wanted to say or not. Cristina has uploaded her slides already here.

I hope people will understand what I’m about with Artefact-Actor-Networks and ask good questions. Here are my slides:

Tags are the new classification systems for nearly all current web applications. But how do you keep track on where you posted, linked, commented or uploaded stuff. Florian Bailey posted a simple but effective idea to do this (HT to René Sprotte for linking me to this):

My problem is how to aggregate everything I publish easily. I tried various ways to do this. For comments there are services like disqus but sadly only a few sites actually integrate it, Facebook and Friendfeed are partly an answer to it but even with them I can only add sites where I have an account ( or that allow me to use my facebook account) or a public RSS Feed is available.

At the end, all of these services only work with some sites, the only global services that work on every site are search engines.

So I’m now trying to aggregate everything I publish with google.

For this I created my personal tag, it’s a unique string I will add to every kind of content I publish anywhere on the internet. And Google will do the rest.

My Personal Tag is: #ptfjib80
# – as identifier of a tag
pt – personal tag
fjib80 – as unique string

I like the idea because it so simple, clean and pretty straightforward. I’ll try to use my personal tag #ptwollepb999 from now on. What about you?

This week I had the opportunity to present the idea of Artefact-Actor-Networks at the CollaborateCom 2009 conference in Washington D.C. – a conference mainly focussing on collaborative computing and its applications in networking and at the workplace.
Abstract:

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.

There is much going on these days at Twitter. After they introduced the new lists feature last week and a spanish version of Twitter, today they roll out a limited access to the new re-tweet feature. I can’t wait to see it in action and implemented in Artefact-Actor-Networks – re-tweets will be the next step of mooring Twitter in the Semantic Web. Hopefully they will allow the geolocation for single tweets soon, which would be another great step in a better connected and semantically annotated web world.

The lists feature obtained mixed feedback. Some people like it that they can put their followers in lists according to their location, community, language or any other criterium, others are saying it was a snapshot of the Twitter team. If you look at the profile of Tim Berners-Lee you’ll see he is listed nearly 1200 times. A lot of these lists are  related to technology, the WWW and semantic web. Unfortunately (or luckily) there is not the One technology lists where anyone you get started (mainly because such a list is pure imagination). On the other hand, if you look at the lists that Stephen Downes is on, you’ll get 90 lists, all dealing with education and learning in the web 2.0. Like so often each coin has to sides and we will need to sit and wait what Twitter lists will be useful for. For me I like it that now I can sync my lists with several tools and the Twitter website – a great gain in mobility and consistency.

If you are developing applications built on the Twitter API maybe the experimental Twitter Streaming API is interesting for you.
