Why Wikipedia Articles Vary So Much In Quality

Hugh Pickens writes "A new study shows that the patterns of collaboration among Wikipedia contributors directly affect the quality of an article. 'These collaboration patterns either help increase quality or are detrimental to data quality,' says Sudha Ram at the University of Arizona. Wikipedia has an internal quality rating system for entries, with featured articles at the top, followed by A, B, and C-level entries. Ram and graduate student Jun Liu randomly collected 400 articles at each quality level. 'We used data mining techniques and identified various patterns of collaboration based on the provenance or, more specifically, who does what to Wikipedia articles,' says Ram. The researchers identified seven specific roles that Wikipedia contributors play (PDF starting on page 175): Casual Contributor, Starter, Cleaner, Copy Editor, Content Justifier, Watchdog, and All-round Editor. Starters, for example, create sentences but seldom engage in other actions. Content justifiers create sentences and justify them with resources and links. The all-round contributors perform many different functions. 'We then clustered the articles based on these roles and examined the collaboration patterns within each cluster to see what kind of quality resulted,' says Ram. 'We found that all-round contributors dominated the best-quality entries. In the entries with the lowest quality, starters and casual contributors dominated.'"

Really?

Articles written by experienced people with a wide array of skills are stronger than those written by novices? Never could have guessed.

Oh.

I always figured that some of the articles were poor because they were written by Americans, rather than much more intelligent Europeans or Asians.

So what? delete it

Quality

Wikipedia is great for anything involving mathematics or Star Wars. Everything else seems kind of suspect to me.

Exactly. And then these people who revert -any- change without even looking at it. What? An anonymous contributor added a few words to make a phrase make since? Revert it!

In January 2010, Apple announced the iPad.
The iPad is a tablet form factor computer due to be released in 2010.

Within one line of each other, one post is talking about the past tense in 2010 and the future tense in 2010... Oh, the horror!

Re:Quality Ratings

[Anonymous Coward]

So your wordy post was just saying that such objective measures work well, but aren't perfect?

Re:Missing role: deleters

[Darkness404]

Reverted. I wrote that so it must be perfect! How dare someone have the -audacity- to change one of my words on -my- article! What is the world coming to? An encyclopedia where the masses can edit it!?

Audacity is open source, so anyone can have it.

You can easily have an extremely high quality, 100% accurate and in-depth Wikipedia article without a single external reference.

At first I thought you were trolling, but then I checked the facts [wikipedia.org]! With how well-written that article was I can only assume it was someone from Hong Kong.
