The Collective Awareness Platforms for Sustainability and Social Innovation (CAPS) are ICT systems leveraging the emerging "network effect" by combining open online social media, distributed knowledge creation and data from real environments (Internet of Things), in order to create new forms of social innovation.
They are expected to support environmentally aware, grassroots processes and practices to share knowledge, to achieve changes in lifestyle, production and consumption patterns, and to set up more participatory democratic processes.
Web spam pages use various techniques to achieve
higher-than-deserved rankings in a search engine’s
results. While human experts can identify
spam, it is too expensive to manually evaluate a
large number of pages. Instead, we propose techniques
to semi-automatically separate reputable,
good pages from spam. We first select a small set
of seed pages to be evaluated by an expert. Once
we manually identify the reputable seed pages, we
use the link structure of the web to discover other
pages that are likely to be good. In this paper
we discuss possible ways to implement the seed
selection and the discovery of good pages. We
present results of experiments run on the World
Wide Web indexed by AltaVista and evaluate the
performance of our techniques. Our results show
that we can effectively filter out spam from a significant
fraction of the web, based on a good seed
set of less than 200 sites.
Twitter recently transitioned to OAuth, but the social network's implementation of the new authentication system has some serious flaws. Ars shows how easy it was to compromise the secret key of Twitter's own official client application for Android.
[updated with Tagommenders paper – thanks Shilad.] The organizers of the World Wide Web conference recently announced the list of accepted papers for this year’s event. In the Social Networks and Web 2.0 track (chaired by Elisa Bertino and Lada...

Lately, we've been working hard to improve BibSonomy's social features. With the recent release we introduced another unique feature that was not announced until now. Following the intuition that secrets are always shared among best friends, our idea is to connect you to people who have the same login password for BibSonomy as you.
This is an outstanding feature that other social networking sites lack up to now - usually, you only get buddies recommended by some black-box algorithm. Our solution is more targeted towards the idea that great minds think alike, and hence choose the same password.
So if you have the same password as other users in BibSonomy, you'll see them in the sidebar in the new "your password buddies" section:
Just have a look at your personal page to get to know your possible new buddies.
Please note that it is possible that some of your password buddies have another password than you because of the possible hash collisions of the MD5 algorithm. Unfortunately we can not solve this issue because we don't store the plain text password, but we are working on an extension of the MD5 algorithm that produces no collisions.
Happy secret sharing!
Your BibSonomy team
