Text similarity was computed using Ted Pedersen's Text-Similarity module. It measures the similarity of two documents based on the number of shared words scaled by the lengths of the files. Text similarity computes the F-Measure, the Dice Coefficient, the Cosine, and the Lesk measure.
The table above includes the results when running the command: perl ./bin/text_similarity.pl --type Text::Similarity::Overlaps FILE1 FILE2 (Dice Coefficient)
