Cooperation Speed of Smartmobs using SMS

Tuesday, March 31st, 2009

Interesting discussion on CooperationCommons:

The average time it takes for someone to respond to an SMS text message would be an interesting indicator of cooperation speed for (SMS) smartmob networks.

From this:  “SMS and mobile IM messages seem to hold a much stricter timetable [than instant messaging]. Almost all participants indicated a punctual 5-15 minutes response time at replying to messages they receive.”

Mark Elliott’s firm is providing advice and strategy to emergency services for enabling smart mobs to quickly spot forest fires using text messages.

Mark said: “It’s interesting to think about the network effects of cascading responses, each taking 5-15 minutes – which actually adds up to sizable delays. However this doesn’t take into consideration sending messages to groups, or even how many individual messages might be sent out after receiving one high priority”

Question/Answers @ RecSys Doctoral Symposium 2008

Friday, November 28th, 2008

I came across an interesting blog post by @HDrachsler, who I started following on twitter after this year’s RecSys conference. The post contains a recording of the question/answer time at the RecSys doctoral symposium (which I unfortunately did not attend). The clearest voice in the recording is Prof. Joseph Konstan, who (obviously, I know) has some very interesting things to say about collaborative filtering, recommender system research, and the state of the field. Here are some notes that I jotted down while I was listening: (more…)

Us Now is a ground-breaking documentary project about the power of mass collaboration and the internet – and its potential impact on society. Directed by Ivo Gormley, the film explores how the web is changing the ways we organise ourselves.

Wednesday, December 10, 2008 from 6:00 PM – 8:00 PM (GMT)

Social Computing @ UCL-CS

Tuesday, November 11th, 2008
Today was the long-awaited follow up to the first introductory mobisys seminar. The theme today was on the social computing research going on in the group, or, more specifically, the overlap between social and pervasive research. Only a handful of speakers gave their pitch, since we have heard from Daniele (slides), Sonia, and myself in the last few weeks. The slides from the session are below:

We followed up the pitches with a brainstorming session on the future of mobisys seminars and collaborative work. Lots of great ideas emerged: we are looking forward to incorporating them into our seminar series in the near future!

Get Ready to Rummble!

Friday, June 20th, 2008

The very last session of the IFIPTM 2008 conference was a demo session; there were 3 demos run and the one that I liked the most was Rummble is a web site that, much like other web2.0 ideas, has as foundations a social network: the interesting addition, though (and what makes it so appropriate for a conference on trust) is that when you add a friend you can say how much you trust their opinions. You then go on to “rummble” different locations (shops/restaurants/clubs), by rating, tagging, and describing them with a comment. The neat thing is that combining trust, rating similarity, and social distance, the site can then predict how much you will like other places that you have not rummbled, and colours them accordingly. The site is also fully mobile! (more…)

Trust Drug

Thursday, May 22nd, 2008

Interesting article on the BBC, found by Mo: A nasal spray which increases our trust for strangers is showing promise as a treatment for social phobia, say scientists from Zurich University.

Web Science: Collaboration and Collective Intelligence

Thursday, May 15th, 2008

So many words that we use in a computer science context come from human interactions: trust, recommendations, reputation. So that is why I was very interested when I read about this workshop:

Web Science is an emerging interdisciplinary field that lies at the boundary of Computer Science, Sociology, Psychology, Media, Economics and Law. Its aim is to understand the Web and its impact on the way people think, behave and interact. This workshop is for people who believe that their work could be part of this new discipline and who are interested in helping to define Web Science. We invite position papers on a variety of technical topics with a human slant, including Social Collaboration, Knowledge Interfaces, Collective Intelligence and Emergent Structures.

The call, however, is closed; see (and read) the list of accepted papers on the link above.

‘Ruthlessness gene’ discovered

Monday, April 7th, 2008

Researchers at the Hebrew University in Jerusalem found a link between a gene called AVPR1a and ruthless behaviour in an economic exercise called the ‘Dictator Game’.

Hands-on Education

Wednesday, October 10th, 2007

The GroupLens blog mentioned something I found very interesting; a Google/IBM partnership is offering university students (from a select number of universities) the chance to develop software for large-scale distributed systems. They will be offering students access to lots of dedicated clusters. The website even offers sample content to help lecturers develop their courses! There is also some stuff on web security. Maybe sometime soon this opportunity will come across the Atlantic..

Can I rent your battering ram?

A very neat slideshow about reputation, made by Rentathing, that I saw on .. I’m not sure if it is working here so click on the link to Paolo’s blog if it isn’t!

Mass collaboration – webcast

Friday, September 28th, 2007

I’m reading a very interesting book: Herds by Mark Earls. Here is a talk the author gave in London last week. The event also featured Howard Rheingold who authored Smart Mobs. Simply brilliant!

Collaborative Filtering is Strange

Friday, September 21st, 2007

I just submitted a paper that includes some very strange results that I got when playing around with the different collaborative filtering techniques on the MovieLens dataset. The work was a direct follow up to the new similarity measure I wrote about in my previous post on privacy in distributed recommender systems, and begins by reshaping the way we think about (and try to visualise) collaborative filtering.

Evolutionary game theory

Thursday, September 13th, 2007

London Evolutionary Research Network’s conference is tomorrow (Friday). The program looks interesting and the registration is free! Plus, Michael is giving a talk titled “Beyond the prisoner’s dilemma: a new model of reciprocal altruism”.

Collaborative computation

Tuesday, July 24th, 2007

An interesting example of mobile surveillance system. Would there be the possibility to introduce collaboration among the robots?


Bio-inspired morphing-wing micro aerial vehicle

“Aerospace engineering students at TU Delft, together with the Department of Experimental Zoology of Wageningen University designed the RoboSwift. RoboSwift is a micro airplane fitted with movable wings, inspired by the common swift, one of nature’s most efficient flyers. The micro airplane will have unprecedented wing characteristics; the wing geometry as well as the wing surface area can be adjusted continuously. This makes RoboSwift more maneuverable and efficient. Resembling the common swift, RoboSwift will be able to go undetected while using its three micro cameras to perform surveillance on vehicles and people on the ground. Furthermore, it can be employed to observe swifts in flight, thus enabling new biological research.”

More details here.

The UltraSwarm project (another intersting project is from the University of Sussex) is another example of a possible application in which mobile collaborative computation can take place among robots (helicopters).

“This study will investigate methods for achieving useful and controlled flocking in a swarm of small co-axial rotor helicopters by developing an accurate model of the vehicles and their aerodynamic interactions, and using this in simulation to optimise flocking performance before real-world testing.
The project combines two key ideas:

* Using biologically inspired rules of group behaviour (flocking) to enable a group of UAVs to control its own motion
* Wirelessly networking the swarm members together to form a single powerful computing resource

The term flocking, derived from flocks of birds, refers to the coordinated movement of a group of individuals such that they move with approximately the same velocity and inter-agent distance.”
