WikiTrust

Friday, June 27th, 2008

Interesting project by the University of California Santa Cruz (UCSC) Wiki Lab: WikiTrust, a project in studying author repuation and text trust on Wikipedia.

How is the trust computed?

The trust of text is computed in two steps:

  • First, we compute the reputation of each author by analyzing the author’s contributions. When an author makes a contribution that is preserved in subsequent edits, the author gains reputation. When an author makes a contribution that is undone or reverted quickly, the author loses reputation.
  • The trust value of a new word is proportional to the reputation of its author. When subsequent authors edit the page, words that are left unchanged gain trust: by leaving them there, the authors implicitly agree with them. Words closer to the edit gain more trust, as the author of the edit is likely to have paid more attention to them. In contrast, text that has been rearranged (new text, text at the border of cut-and-paste, etc) has again a reputation proportional to the author of the edit.

Ameritocracy: new social fact-checking platform

Thursday, June 19th, 2008

I just signed up for Ameritocracy, a new social web app (currently in beta) for collaborative fact-checking.

From their blog:

About Ameritocracy

Ameritocracy is a user generated content site that allows people to rate the credibility of statements made by our leaders and information gatekeepers such as media outlets and businesses. Our reputation system helps to make the information you read more credible, and the succinct nature of the content will help anyone keep up with social and political news.

From the about page:

What is Ameritocracy?

The internet today is pretty neat. It’s given us access to more information than any previous publishing medium, and gives everyone with a connection the tools to broadcast their views to the masses. With so many opinions, we can learn about all sides of any issue, but it still takes a lot of time to do the research. Ameritocracy was born out of this frustration of not knowing who to trust and not having the time to try to figure it out.

Our goal is to help people cut through the noise and gain quick access to the whole picture. We want to encourage a healthy skepticism of all claims, and offer a meaningful way to participate in the dialogue between the people who consume information and the people who own it. We want to give the public a chance to say, “We’re listening”, and demand that we be listened to as well.

How does it work?

The core features of Ameritocracy are adding statements (made by a person or organization) and assessing statements. For example, if you hear Jane Doe say something on tv that you find questionable, you can submit that statement to the site to see what the community has to say about it, or you can add your own assessment. Members can then rate Jane Doe’s statement for credibility and relevancy, add their own assessments, or post a comment.

From this, Jane Doe will develop a reputation based on the community ratings, and you and your sources will develop a positive reputation so long as no one identifies your submission as a misquote or deliberately inaccurate information. The goal is to get a few different perspectives for each statement, so anyone looking to know more about a statement can get a broader picture and make their own assessment.

There will be some really exciting trends to watch during this process, such as what the public feels about certain topics, how public opinion changes over time, and how the government, media and business react to the views of the Ameritocracy community.

Over on the IPDI blog, Julie Germany has an interview with Porter Bayne, one of the co-founders (she’s also giving out invite codes so check it out): Building Ameritocracy one quote at a time

At first glance, this looks very similar to Munich, Germany-based Trupoli (which I looked at briefly back in December).

Following a long year of lackluster garden engagement, the time has come to once again green the backyard.

In an effort to fully maximize value, this year will be herbs only (strawberries didn’t yield enough results, and the vegetables were pretty much all eaten by our little friends on four feet).

Sorry, mates, not this time!

Basil, rosemary, Italian parsley have already been added in large quantities. Mint and a few other weeds will follow shortly.

Tim Russert

Friday, June 13th, 2008

Journalism here in the US suffered a big loss today: NBC’s Tim Russert dead at 58

Of his background as a Democratic political operative, Russert said, “My views are not important.”

“Lawrence Spivak, who founded ‘Meet the Press,’ told me before he died that the job of the host is to learn as much as you can about your guest’s positions and take the other side,” he said in a 2007 interview with Time magazine. “And to do that in a persistent and civil way. And that’s what I try to do every Sunday.”

You did a good job, Tim!
