Tonight: Is internet-based social networking antisocial?

Monday, June 15th, 2009

Peter Bentley of CS UCL is hosting the Royal Institution’s cafe scientifique at 7pm at the RI cafe.

Sociologists and data miners come together to advance social computing

Tuesday, April 28th, 2009

(from here) From: Gregory Piatetsky-Shapiro; SBP09 Second Workshop on Social Computing, Behavioral Modeling, and Prediction

  • keynote presentation by Phillip Bonacich (UCLA, Emeritus), about Power and Exploitation in Exchange Networks: A Social-Psychological Model.
  • Mary Lou Maher (NSF) talked about Research Challenges for Computationally Enabled Social and Collective Intelligence.She gave a number of collective intelligence examples, including open source systems, recommender systems, search engines, and Wikipedia.
  • William H. Batchelder, a leading expert on psychology and social sciences, talked about Cultural Consensus Theory, which is an approach to pooling information from different sources.Batchelder showed that a social network model, with a good deal of math, a Bayesian formulation and MCMC methods, can be used to estimate the consensus answers.
  • Shade Shutters (ASU) talked about Punishment, Rational Expectations, and Relative Payoffs.
  • Many posters were presented during a workshop dinner the first night 
  • On the second workshop day, Alex Penland from MIT Media Lab gave a keynote talk on Reality Mining: From Profiles and Demographics to Behavior .Dr. Penland is very sensitive to privacy issues and says these sensors should not be used to spy on employees. He suggests that deployment should be on voluntary data with individuals owning the data and have the opportunity to review their data each day. Learning can be done effectively from anonymized profiles. Dr. Penland company Sense Networks is now commercializing these applications in macrosense™ and Citysense™

Some Results on Coding for Flash Memory

11:15 AM, Thursday, 16th April
Roberts G06 (Sir Ambrose Fleming LT)

Abstract: Flash memory is rapidly becoming the technology of choice for storage in several settings. But flash memory behaves differently than other memory systems, making us rethink the basic ways we represent data. In this talk we’ll consider the question of how to code data for flash memory systems. Although our framework will be primarily theoretical, it will shed light on some of the basic issues underlying the use of flash memory systems, including what considerations need to be kept in mind when designing algorithms or data structures for such systems.

Bio: Michael Mitzenmacher is a Professor of Computer Science in the School of Engineering and Applied Sciences at Harvard University. Michael has authored or co-authored over 140 conference and journal publications on a variety of topics, including Internet algorithms, hashing, load-balancing, erasure codes, error-correcting codes, compression, bin-packing, and power laws. His work on low-density parity-check codes shared the 2002 IEEE Information Theory Society Best Paper Award. His textbook on probabilistic techniques in computer science, co-written with Eli Upfal, was published in 2005 by Cambridge University Press. This year, he is serving as chair of STOC 2009 and on the PC of SIGCOMM 2009.

Michael Mitzenmacher graduated summa cum laude with a degree in mathematics and computer science from Harvard in 1991. After studying math for a year in Cambridge, England, on the Churchill Scholarship, he obtained his Ph. D. in computer science at U.C. Berkeley in 1996. He then worked at Digital Systems Research Center until joining the Harvard faculty in 1999.

The Internet for Activists: The Good and The Ugly

Saturday, March 14th, 2009

I just got back from the Internet for Activists conference. It was a very stimulating experience: Tim Ireland of Bloggerheads spoke about the importance of SEO techniques for activists who wish to get their message out there. Laurie Penny who writes on Penny Red gave activist bloggers two main recommendations:

  • Engage in comments (openly accept comments and REPLY to them; however, don’t let stalkers take over your blog and do so by moderating comments with clear guidelines)
  • Go for quality not quantity (write less posts but write them well)

who does her PhD at UCL recounted her experience of using Facebook for rescuing Guy Njike from deportation. Finally, Karin Robinson talked about how she coordinated the activities of the Americans Abroad for Obama campaign. Interestingly, people earned points on the Obama social net website only if they didn’t sit in front of their computers but went out there.

These examples of online activism show that social net websites reduce communication and coordination costs and, as such, help people to organize off-line activities as well: people who live in the same neighborhood physically meet for the first time because of shared interests on the Internet (e.g., activism). Those examples also show that there is little merit in Susan Greenfield’s contemptible campaign. Frankly I don’t blame those who think she should go.

During these presentations I was thinking about a student project idea:

  • Design a platform for building campaigns. Ideally, such platforms should be easy to use and should allow people to not only engage in online activities but also to easily coordinate their off-line activities (e.g., street demonstrations, writing letters to MPs)

The dark side of activism: The Ugly Mask

The representative of Anonymous was also invited, and his (?) intervention was quite controversial. He concealed his identity with a mask and spoke on behalf of Anonymous. Here is what Anonymous is:

  • (from The Economist) Now Scientology is under attack from a group of internet activists known only as Anonymous. Organised from a Wikipedia-style website (editable by anyone) and through anonymous internet chat rooms, “Project Chanology”, as the initiative is known, presents no easy target for Scientology’s lawyers. It is promoting cyberwarfare techniques normally associated with extortionists, spies and terrorists. Called “distributed denial of service attacks”, these typically involve using networks of infected computers to bombard the target’s websites and servers with bogus requests for data, causing them to crash. Even governments find this troublesome.

The campaign against Scientology may all be very well. However, the assumption behind these self-organizing activists is that they are always right (they are anonymous and, as such, they are not accountable). Unfortunately, this assumption does not always hold. Indeed, most of the activities the Mask presented were either jokes the audience failed to understand or Internet bullying activities. Worringly, this self-organizing entity finds it acceptable to launch DoS attacks against websites that happen to disagree with the entity’s views. Is this the right way to go? Can this be even called activism?

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…)

A Pitch on Future Recommender Systems

Thursday, November 27th, 2008

Yesterday I attended a workshop that was aimed at fostering research collaboration between our department and BSkyB. After a short introduction by the head of the department, a number of members of staff gave short (10 minute) pitches about their past and current research, and areas they are interested in for potential collaboration. The range of work being done in the department is huge- perhaps this deserves a post of its own.
