This presentation explores the role that context can play in the detection of contract cheating. The paper looks at how context can be identified, both directly on the posts made on agency websites, and through wider observation of the contract cheating landscape and makes some initial proposals as to how intelligent software to detect contract cheating could be developed.

Transcript

  • 1. @DrLancaster slideshare.net/ThomasLancaster 1ThomasLancaster.co.uk An Initial Analysis Of The Contextual Information Available Within Auction Posts On Contract Cheating Agency Websites Thomas Lancaster and Robert Clarke Birmingham City University ICAES 2014
  • 2. @DrLancaster slideshare.net/ThomasLancaster 2ThomasLancaster.co.uk Background
  • 3. @DrLancaster slideshare.net/ThomasLancaster 3ThomasLancaster.co.uk The Role Of The Authors In Contract Cheating Research Dr. Thomas Lancaster Senior Lecturer in Computing PhD “Effective And Efficient Plagiarism Detection” Programme Leader BSc Computer Science Lead of Innovations in Computing Education Group Robert Clarke Educational Consultant Current Visiting Lecturer/Former Principal Lecturer 30 Years Experience Teaching At BCU 19,000 Attempts at Contract Cheating Found
  • 4. @DrLancaster slideshare.net/ThomasLancaster 4ThomasLancaster.co.uk “Originators” Of Contract Cheating http://news.bbc.co.uk/1/hi/education/5071886.stm
  • 5. @DrLancaster slideshare.net/ThomasLancaster 5ThomasLancaster.co.uk
  • 6. @DrLancaster slideshare.net/ThomasLancaster 6ThomasLancaster.co.uk Not Turnitin Turnitin is a text similarity detection engine, which determines when two pieces of text share commonality Contract Cheating produces original work, so will not be detected using Turnitin
  • 7. @DrLancaster slideshare.net/ThomasLancaster 7ThomasLancaster.co.uk The Role Of Context
  • 8. @DrLancaster slideshare.net/ThomasLancaster 8ThomasLancaster.co.uk Can Context Help? The paper hypothesis: Knowing the context of a request placed online by a student looking to cheat will help to attribute the cheating student
  • 9. @DrLancaster slideshare.net/ThomasLancaster 9ThomasLancaster.co.uk Two Stages Of Attribution 1. Identify from which university/academic institution an attempt at cheating has been taken from 2. Identify which individual student out of a larger cohort attempted to cheat
  • 10. @DrLancaster slideshare.net/ThomasLancaster 10ThomasLancaster.co.uk Examples
  • 11. @DrLancaster slideshare.net/ThomasLancaster 11ThomasLancaster.co.uk Example Of Contract Cheating (1)
  • 12. @DrLancaster slideshare.net/ThomasLancaster 12ThomasLancaster.co.uk Example Of Contract Cheating (2)
  • 13. @DrLancaster slideshare.net/ThomasLancaster 13ThomasLancaster.co.uk Towards Intelligent Detection
  • 14. @DrLancaster slideshare.net/ThomasLancaster 14ThomasLancaster.co.uk Automated Detection An automated system to detect contract cheating using agency sites, such as Freelancer.com, would need to scrape/automatically collect as much contextual information as possible Context is largely used in this way by current manual detection methods (by a detective)
  • 15. @DrLancaster slideshare.net/ThomasLancaster 15ThomasLancaster.co.uk Examples Of Available Context The text of the cheating request (does this match known assignment content? does this contain institutional identifiers?) The username/history/photo/stated location of the requester (does this match information on other sites?)
  • 16. @DrLancaster slideshare.net/ThomasLancaster 16ThomasLancaster.co.uk Missing Context (Can This Be Gathered?) Copies of all assignment briefs provided worldwide, in all subjects Full profiles of all students worldwide, with identifying/characteristic information
  • 17. @DrLancaster slideshare.net/ThomasLancaster 17ThomasLancaster.co.uk An Approximation Of These Databases Suggestion, use Google to approximate the necessary searches for images, assignment information, contact information Use Facebook for social media searches for student information Augment this using Turnitin, which contains some assignment briefs (e.g. embedded within student uploads)
  • 18. @DrLancaster slideshare.net/ThomasLancaster 18ThomasLancaster.co.uk Recommendations
  • 19. @DrLancaster slideshare.net/ThomasLancaster 19ThomasLancaster.co.uk Partial Solutions The Contract Cheating proposes multiple partial solutions: Six-Stage Contract Cheating Detection Process Use of Stylometrics Watermarking of assignments to allow cheating students to be identified
  • 20. @DrLancaster slideshare.net/ThomasLancaster 20ThomasLancaster.co.uk The Community Role The wider community can support Contract Cheating detection by developing fully and partially automated tools Student and research projects have a role to play here Embedding the use of contextual information within these tools should aid in the detective process
  • 21. @DrLancaster slideshare.net/ThomasLancaster 21ThomasLancaster.co.uk Continued Awareness There are still academics who are unaware that students can cheat, or who seem tempted to “turn a blind eye” Changes to pedagogy and to staff attitudes are needed to continue to preserve the value of academic qualifications
  • 22. @DrLancaster slideshare.net/ThomasLancaster 22ThomasLancaster.co.uk More Information
  • 23. @DrLancaster slideshare.net/ThomasLancaster 23ThomasLancaster.co.uk For More Information Thomas Lancaster: http://thomaslancaster.co.uk thomas.lancaster@bcu.ac.uk Robert Clarke: robert.clarke@bcu.ac.uk Slides Available At: http://slideshare.net/ThomasLancaster Video Discussion Available At: http://youtube.com/DrThomasLancaster
  • 24. @DrLancaster slideshare.net/ThomasLancaster 24ThomasLancaster.co.uk Discussion How can context for contract cheating on agency sites be automatically gathered? Can existing systems be used to augment automatically gathered contextual information? What algorithmic techniques are most suited for the detection of contract cheating?
