Practical Session

Concrete description of work assignment for students for the second one-hour part of the lecture. The work will consist of tasks connected with practical implementations of algorithms connected with the current topic (probably not the state-of-the-art algorithms mentioned in the first part) and with real data. Students can test the algorithms, evaluate them and possibly try some short adaptations for various subtasks.

Students can also be required to generate some results of their work and hand them in to prove completing the tasks.

Resources:

  • A set of documents and plagiates !TODO
  • A frame script in Python for plagiarism detection !TODO
  • A description of several basic methods for plagiarism detection evaluated by HaCohen?-Kerner et al. !TODO

The task:

  • !TODO instructions
  • The student will choose a method for plagiarism detection and implement it as a function in the frame script.
  • Evaluation: precision, recall, F1 (the calculaton will be a part of the frame script).
