Estimate how much two texts overlap using shared vocabulary.
The shared word set is measured against combined and union counts to express how much the texts overlap proportionally. Spotting overlap early catches accidental repetition or near-duplicate sections before content gets flagged as recycled.
Text Similarity
Dice similarity = 2 x overlap / (A + B); Jaccard = overlap / (A + B - overlap)
