WikiTrust 2.0

The WikiTrust 2.0 project aims at computing a reputation value for Wikipedia text that indicates the extent to which Wikipedia text has withstood revision. This index of text reputation can be used to spot new, and as yet unrevised, contributions, and it can also be used to automatically select a good-quality, recent revision for a Wikipedia page.

The old WikiTrust project was written in Ocaml, a language that made it difficult for many to contribute, and was based on a rather monolithic analysis of whole Wikipedias at a time. WikiTrust 2.0 will be written in Python, and will be a scalable and flexible service, where the analysis can start from particularly relevant sets of pages (e.g., pages on candidates to political elections, medical pages, and so forth), and then gradually expand.

Among the outputs we aim at providing are:

• Text trust, which can be used to spot recent unrevised changes to pages.
• Selection of high-quality, recent revisions of Wikipedia pages, for instance for inclusion in internet-in-a-box type devices, or for use in schools.

Resources

• Git repository, containing code and documentation
• Google discussion group (project members only; you can apply for membership)
