Rapport: Can Social Bookmarking Improve Web Search?

Paul Heymann, Georgia Koutrika, Hector Garcia-Molina, Can Social Bookmarking Improve Web Search? (source: Stanford InfoLab):

"Social bookmarking is a recent phenomenon which has the potential to give us a great deal of data about pages on the web. One major question is whether that data can be used to augment systems like web search. To answer this question, over the past year we have gathered what we believe to be the largest dataset from a social bookmarking site yet analyzed by academic researchers. Our dataset represents about forty million bookmarks from the social bookmarking site del.icio.us. We contribute a characterization of posts to del.icio.us: how many bookmarks exist (about 115 million), how fast is it growing, and how active are the URLs being posted about (quite active). We also contribute a characterization of tags used by bookmarkers. We found that certain tags tend to gravitate towards certain domains, and vice versa. We also found that tags occur in over 50 percent of the pages that they annotate, and in only 20 percent of cases do they not occur in the page text, backlink page text, or forward link page text of the pages they annotate. We conclude that social bookmarking can provide search data not currently provided by other sources, though it may currently lack the size and distribution of tags necessary to make a significant impact."

Veropedia

"What is Veropedia?
Veropedia is a collaborative effort by a group of Wikipedians to collect the best of Wikipedia's content, clean it up, vet it, and save it for all time. These articles are stable and cannot be edited, The result is a quality stable version that can be trusted by students, teachers, and anyone else who is looking for top-notch, reliable information.

So is this just another mirror?
Absolutely not! In order to be included in Veropedia, articles must meet very strict criteria of our own. There can be no cleanup tags, no "citation needed" tags, no disambiguation links, no dead external links, and no fair use images. In addition, each article will be given to recognized academics and experts to review. These experts can either provide their stamp of approval or make suggestions as to how the article can be improved further. In that way, users will know that the article is reliable.

So is this an expert-driven project, like Citizendium?
Not at all. Our material is written by Wikipedia contributors. The role of experts and academics will be to check it and, ideally, approve it. Their comments will be given back to our contributors to incorporate back into the articles to make them even better. We provide a meta-layer for Wikipedia, or in simpler terms, if you think of Wikipedia as a diamond mine, we think of ourselves as jewelers who provide a finished product to the public. We think of this as true collaboration.

Can Veropedia articles be improved?
Certainly, but the work to improve the article takes place on Wikipedia, and the newer version is imported back to Veropedia. In that way, both Wikipedia and Veropedia benefit from better quality content.

Does Veropedia have all of Wikipedia's articles?
No, in fact, at this early stage, we have a very small fraction of the articles in Wikipedia. While we are growing every day, our focus is on the core articles of a good set of encyclopedias, that will be most useful to students and teachers. Our focus is and always will be on the quality of our articles, rather than on their number." [ suite ]

A propos de Facebook

Dans la série "7 things you should know about..." d'Educause, voici celui consacré à Facebook "nouvelle" version:

"Since ELI's first brief on Facebook, the social networking site originally developed for college and university students has become available to anyone. It now offers new ways of organizing social networks as well as extensive new features and access to other Web applications. Users can now manage online identities and engage other users much more easily. They also enjoy privacy policies that give them unprecedented control over how their personal information is handled on the site."

Socialpoint pour MS SharePoint

Au lendemain de l'annonce du rachat de JotSpot par Google, Socialtext lance Socialpoint, une solution wiki d'entreprise pour les utilisateurs de Microsoft SharePoint (plateforme collaborative). Socialtext offre également aux ex-clients de JotSpot une migration gratuite vers sa plateforme et un an d'utilisation gratuite. Pour rappel, JotSpot-Google sera, lui, gratuit. Mais le CEO de Socialtext, Ross Mayfield, explique que les ex-clients de JotSpot ont tout à gagner en passant chez lui (fiabilité, stabilité, professionnalisme).

Citizendium

Un des co-fondateurs de Wikipedia, Larry Sanger, a lancé le projet Citizendium: un outil wiki et très très proche de Wikipedia, à la différence que les contributeurs de Citizendium sont parrainnés et responsables de ce qu'ils écrivent: "to allow regular people a place to work under the direction of experts, and in which personal accountability--including the use of real names--is expected. In short, we want to create a responsible community and a good global citizen".

Màj (23 oct.): cf. aussi cet article dans TechNewsWorld, "Wikipedia and the trust factor", où il est également question de l'initiative de L. Sanger.
