An Information Cascade

I’ve been reading Networks, Crowds, and Markets, a great textbook by David Easley and Jon Kleinberg. I’m very grateful to Cambridge University Press for surprising me with an unsolicited review copy. I’m more than halfway through its 700+ pages. Much of the material is familiar in this “interdisciplinary look at economics, sociology, computing and information [...] → Read More: An Information Cascade

Learning to apply the DMCA

Panos Ipeirotis posted a great, (unintentionally) funny letter one of his students received from some clueless person claiming that the student’s site warrants a DMCA take-down because it allegedly deprived another similar site of $0.52/day in revenue by affecting its page ranking in some search results.

Political discourse in Italian over the period shows marked use of negative emoticons, and in Swedish, positive emoticons. → Read More: Emoticonsciousness

Relative status of journal and conference publications in computer science

Though computer scientists agree that conference publications enjoy greater status in computer science than in other disciplines, there is little quantitative evidence to support this view. The importance of journal publication in academic promotion makes it a highly personal issue, since focusing exclusively on journal papers misses many significant papers published by CS conferences. → Read More: Relative status of journal and conference publications in computer science

Preliminary Call – MASoc 2011

This workshop focuses on Information Retrieval (IR) challenges for dynamic, mobile adhoc societies (MASocs). Current social networks are based on the typical web paradigm where support from fixed infrastructures is required, and therefore interactions are largely based on users’ permanent information needs and characteristics. On the other hand, due to the increasing popularity and technological advances in mobile devices (increased dependability, connectivity, user-friendliness, battery life) we can envision a new type of decentralised social network able to directly address ephemeral information needs and interactions. IR and related technologies will be at the core of this new paradigm due to its inherent lack of fixed points of reference. → Read More: Preliminary Call – MASoc 2011
