Calculations:
Matching Percentage % = M(10681345, 10676324) / N(11) × 100 = (2/11) × 100 = 18.18%
Matching Percentage % = M(O1, O2) / N(O1) × 100% (1)
Matching Percentage % = M(10681345, 10671473) / N(11) × 100 = (11/11) × 100 = 100%






Difficulties

 Some course descriptions did not express the course
 topics clearly and explicitly but were rather vague.

 Some of the course descriptions were short and I was
 unable to extract various terms from them.

Some course descriptions were full of stop words. 

Sometimes two courses offer the same academic material, but one of them has a weak description.





Thank you for listening
