The main idea that triggered the description change was that for the automatic spam detection based on content there are third party tools, which are tested and optimized by extensive usage. Starting from scratch with a new algorithm implementation would only waste time in the wrong place. However, there are other places that still need intelligent data processing, like detecting what is a spam bot and what is a productive user, and I don't know if there is a tool for checking content updates; a third party spam detection tool is good for checking added comments, but it will fail to detect evil edits, like adding cursing to pages. Note that the objective is to have an effective vandalism detection and recovery system in XWiki. How we do this is still a subject open to discussions. If you do have some ideas and you want to use your machine learning knowledge to make a smart tool for this purpose, we'd be happy to hear and discuss your vision on this project. So, please let us know how you would like to approach the problem. This is one of the more open projects, where lots of ideas are expected from the student. Looking forward to hearing your proposal, -- Sergiu Dumitriu http://purl.org/net/sergiu/
