My thesis in the Social Semantic Web
o Investigate Wikipedia discussionso Provide semantic supporto Evaluate the impact on the community
Deletion threatens Wikipedia
o 1 in 4 new Wikipedia articles is deleted – within minutes or hours
o Demotivating! • 1 in 3 newcomers start by writing a new article• 7X less likely to stay if their article is deleted!
o Can we support editor retention?
Article creators
o Misunderstand policy• “I do understand that articles on wikipedia need to
be sourced… it is due to have two [sources] once [our website goes] live”
o Express high levels of emotion• “To be honest it's been a real turn off adding
articles to WP and I don't think I will add articles again. So smile and enjoy.”
o Learn from discussions• “much as it would break my heart … it is perhaps
sensible that the piece is deleted.”
Jodi Schneider, Alexandre Passant, and Stefan Decker. “Deletion Discussions in Wikipedia: Decision Factors and Outcomes.” In WikiSym2012.
Novices’ arguments
o Structurally different to experts’ argumentso More problematic arguments from novices
• Personal preference• Requesting a favor• Analogy to other cases• No harm in keeping an article• Large number of search engine hits
Jodi Schneider, Krystian Samp, Alexandre Passant, Stefan Decker. “Arguments about Deletion: How Experience Improves the Acceptability of Arguments in Ad-hoc Online Task Groups”. In CSCW 2013.
Articulate criteria
4 Factors cover• 91% of
comments• 70% of
discussions
Factor Example (used to justify `keep')
Notability Anyone covered by another encyclopedic reference is considered notable enough for inclusion in Wikipedia.
Sources Basic information about this album at a minimum is certainly verifiable, it's a major label release, and a highly notable band.
Maintenance
…this article is savable but at its current state, needs a lot of improvement.
Bias It is by no means spam (it does not promote the products).
Other I'm advocating a blanket "hangon" for all articles on newly-drafted players
Jodi Schneider, Alexandre Passant, and Stefan Decker. “Deletion Discussions in Wikipedia: Decision Factors and Outcomes.” In WikiSym2012.
Add semantic structure
Implementation based on Jodi Schneider and Krystian Samp “Alternative Interfaces for Deletion Discussions in Wikipedia: Some Proposals Using Decision Factors. [Demo]” In WikiSym2012.
84% prefer our system
“Information is structured and I can quickly get an overview of the key arguments.”
“The ability to navigate the comments made it a bit easier to filter my mind set and to come to a conclusion.”
“It offers the structure needed to consider each factor separately, thus making the decision easier. Also, the number of comments per factor offers a quick indication of the relevance and the deepness of the decision.”
