Wikibu, rating Wikipedia articles on statistical information

I just discovered this great tool called Wikibu. Wikibu is an initiative and research project form the Zentrum für Bildungsinformatik of the Pädagogischen Hochschule PHBern in Switzerland. It is only available for the German Wikipedia, but it looks promising.

The principle is quite simple (well, it might be technically difficult, but that's another story): its goal is to rate the potential quality of Wikipedia articles on a few objective markers, including: Wikibu, ratings for the Michael Jackson article

  • Number of visits
  • Number of authors having participated to the construction of the article
  • Number of backlinks within Wikipedia
  • Number of sources used in the article [1]

It also takes into account whether the article is being heavily worked on, and if the discussion page is being used, which allows to see if the topic is either "hot in the news" or maybe "heavily discussed" due to disagreements. It also takes into account the ratings given by the Wikipedia Community (good article - lesenswert- or a featured article - exzellenter Artikel). Wikibu also lists the different authors of the article, assessing their participation in writing it.

Finally, it lists the necessary links to the different pages of the article (discussion, history) and a link which prompts to work on the article, as an incentive to make it better.

Wikibu is meant to be a tool for education. It does not pretend to be able to rate the quality of the content, but rather aims at giving a few pointers as to what makes a potentially good article in Wikipedia. Based on statistical analysis, it provides a good starting point to evaluate the content and most important, gives a good overview of how an article is built, taking into account the most symptomatic pieces of the community process and making them clear for readers who might not know where to look for discussion or authors.

I am looking forward to seeing it extended to other wikipedias, I think it can help both the readers and the contributors to look at Wikipedia in a different way.

See below the ratings on the article "Dolphin" in the German Wikipedia.

There Are Way Too Many Beautiful Pictures...

...on Wikimedia Commons. The vote for the Picture of the Year 2008 has begun and like every year, I am flabbergasted with the amount of amazing pictures that Commons reveals.

I thought I would list here my criteria for choosing the pictures I supported this year. This is how I proceed:

  • Look at the gallery
  • Click on the pictures that catch my eye
  • Enlarge them to see them at full resolution
  • Go back to the credits page to see where the picture comes from.
  • Vote

And these are the criteria I keep in mind when choosing to support a picture or not.

  1. The picture needs to catch my eye. This starts with a thumbnail, so any picture that does not have enough contrast or does not present something "different" does not go past the first page.
  2. The picture needs to be of "good quality". This means a high resolution to start with, but also a picture with as little grain as possible and with details as sharp as possible. In the case of diagrams and animations, the smoothness of the animation or the fact that the diagram is in svg will prevail.Ammonite lamp post at dusk, Lyme Regis - © MichaelMaggs - License CC-BY-SA 3.0
  3. The picture should be of "encyclopedic nature". There are lots of debates about what is an encyclopedic picture, but I guess that for me it means that the picture should find its place as an illustration in one of the Wikimedia projects.
  4. The picture should be clear in its subject. This means that I pay attention to how the picture is cropped, what frame was chosen and whether it illustrates well the subject it is about.
  5. The technical skills that the picture entails. This goes especially for panoramas or macros.
  6. Who took the picture. I must say that I give plus points for pictures taken by "normal contributors" as opposed to pictures imported from Public Domain repositories (such as US governmental organisations). This is my little way of promoting the individual contributor. Mind you, I have supported some "imported" pictures when they were particularly to the point, or when they represent historical views or art pieces.
  7. My subjective opinion or emotion also plays a role, there are pictures I simply love, others I just like. This is the personal factor to my vote. However, there are a few pictures I love but which are in my opinion too far from all of the other criteria to catch my vote as "picture of the year".

You'll find on Commons the list of pics I voted for in the first round.

It's the curse of knowledge, you cannot unlearn it.

For people not working with MediaWiki outside Wikipedia, it is hard to imagine what learning curve you went through when you first started editing.
It's the curse of knowledge; you cannot unlearn it.
Marjon Bakker, in a post to foundation-l

I love that last line! It is so true. And not just for wiki-knowledge. For all knowledge. Getting back to a time you "didn't know" is just impossible.

Why I don't always go for free

Résumé en français : Pourquoi je choisis pas toujours le libre. J'ai peu de photos sur Flickr, comparé aux nombres impressionnants de quelques-uns. La plupart de mes photos sont sous licence Creative Commons, cc-by-sa (paternité-partage à l'identique), mais pas toutes. Je garde la totalité de mes droits par défaut sur toutes les photos où l'on voit et peut reconnaître quelqu'un (que je connais ou pas), pour une raison qui vient d'être illustrée par l'utilisation par l'agence de pub de Virgin Mobile en Australie, qui a utilisé des photos de Flickr sous licence CC-BY (paternité) et en a fait... ce qu'elle a voulu, sans plus se soucier de demander quoi que ce soit, à qui que ce soit. Bien sûr, c'est "libre". Mais dans ces cas-là, je suis pour l'adage qui dit "la liberté des uns s'arrête où commence celle des autres.'"

Wikimedia logo highjacking

Where I am reassured that there are still people with imagination in the Wikimedia projects

I am one of those tedious defenders of the integrity of the Wikimedia logo. It is not, in itself, the best logo ever, but well, the Wikimedia Foundation has enough problems as is trying to differentiate itself from Wikipedia, it deserves at least its own visual identity.

At the beginning, there was the English Wikipedia

And it was good

Hmmm, I am not even sure that this title reflects the utter irony with which I write those words. There has been of late a fantastic number of amazing threads on various Wikimedia mailing lists. Those all started because a team of good-willing people decided they would clean up meta.

Nobody knows everything, but everybody knows something

You just have to find out who knows what

Well, the Nobody knows everything, but everybody knows something has been a long standing slogan for the construction of Wikipedia. However, I am not going to linger on the Wikipedia aspect of it, but rather on the applications I see in other areas, and especially on the organisational area of Wikimedia.

There are people behind nicknames

Where you learn that well...there are people behind nicknames.

A very long time ago, when I started chatting on Yahoo!, I met a whole bunch of people. I was very naive, and the first time I entered a channel, with this notafish nickname, I actually said who I was, where I came from, in short, I did not hide behind the nickname, because I did not know to, and because I suppose I did not see any reason to.

What about the reader ?

Or how Wikipedia addresses its "customers" and how the form reflects the content

N.B. I started this post more than a year ago and never put it on line, so some of the information is somewhat obsolete, but I decided today to take it up again and leave the first part as I had written it then.

Intégristes du copyright

Où l'on se rend compte que le libre n'est pas toujours compris, parfois même par ses plus virulents défenseurs

Il fait pas beau. il fait même carrément froid. Il neige, pour tout vous dire. Et puis je me sens d'humeur trollesque. Donc j'ai pointé mon nez ce matin sur le bistrot Wikipédia. Depuis un certain temps déjà, mes activités au niveau organisationnel (Wikimedia Foundation, Wikimedia France) me laissent peu de temps pour contribuer.

Mais quelle est donc la mission de Wikipédia ?

Où comment se prendre la tête avec un truc qui devrait être évident

Voilà une question que l'on m'a posée trois fois au cours de mon séjour à Paris. Et trois fois dans des circonstances légitimes. Trois fois, je n'ai pas su vraiment répondre. Ou plutôt, la première fois, j'ai fait la sourde oreille, la deuxième, j'ai posé la question à l'envers "Que pensez-vous que soit notre mission ?" et la troisième, j'ai dû convenir du fait que je ne savais pas. Ou plutôt, si. Moi, je sais ce que je fais dans cette organisation, je sais pourquoi je suis là.
