plagiarism_test.rb

To see the original code please go to this link.

The main responsibility of Plagiarism_Check is to determine whether the reviews are just copied from other sources.

Basically, there are four kinds of plagiarism need to be check :

1. whether the review is copied from the submissions of the assignment

2. whether the review is copied from the review questions

3. whether the review is copied from other reviews

4. whether the review is copied from the Internet or other sources, this may be detected through google search

For example, in the test file: expertiza/test/unit/automated_metareview/plagiarism_check_test.rb

the 1st test shows:

test "check for plagiarism true match" do
   review_text = ["The sweet potatoes in the vegetable bin are green with mold. These sweet potatoes in the vegetable bin are fresh."]
   subm_text = ["The sweet potatoes in the vegetable bin are green with mold. These sweet potatoes in the vegetable bin are fresh."]
  
   instance = PlagiarismChecker.new
   assert_equal(true, instance.check_for_plagiarism(review_text, subm_text))
end

Link to VCL

The purpose of running the VCL server is to let you make sure that expertiza is still working properly using our refactored code. The first VCL link is seeded with the expertiza-scrubbed.sql file which includes questionnaires and courses and assignments so that it is easy to verify that reviews work. You only need to make users and then have them do reviews on one another. 1. http://152.46.20.30:3000/ Username: admin, password:password 2. If the first one does not work, please use this one. http://vclv99-129.hpc.ncsu.edu:3000 Username: admin, password: admin 3. If none of these work, please do not do your review in a hurry, shoot us an email, we will fix it as soon as possible. (yhuang25@ncsu.edu, ysun6@ncsu.edu, grimes.caroline@gmail.com). Thank you so much!
