Here is a presentation of a recent paper I coauthored with Robert Clarke presented in video form. The presentation muses on the detection opportunities afforded to contract cheating through a consideration of the wider context on which requests on agency sites are made.
The video is also available on the YouTube account for Thomas Lancaster
Automated methods of detecting contract cheating are one of the areas in which there is currently a real need. Whilst people like Robert Clarke provide a human detection process, this can never be 100% successful. For instance, there’s no way that a human can be continually monitoring every post on an agency site such as Freelancer.
Whilst an intelligent system would not be a sole solution to this problem, since it would require human checking, it would also increase the consistency through which posts are monitored, and would allow more information from such sites to be captured.
