The Jaccard Similarity Coefficient is a statistical formula used to measure the structural similarity between two sets.
J(A,B) = |A ∩ B| / |A ∪ B|
In this search engine;
Set A represents the unique keywords of the first course, and
Set B represents the second course's unique keywords found in the catalog (excluding conjunctions).
The algorithm calculates a deterministic overlap ratio by dividing the
number of common words by the
total number of unique words in both courses. This method does not perform semantic analysis; it is directly based on the terminological intersection of the curriculum.
