TermSimilarity constructor

TermSimilarity(String term, String other, { int k = 2, })

Returns a immutable TermSimilarity for term and other.

• k is the k-gram length used to calculate jaccardSimilarity, defaults to 2.

Not case-sensitive.

Implementation

factory TermSimilarity(String term, String other, {int k = 2}) {
  final editDistance = term.editDistance(other);
  final editSimilarity = _getEditSimilarity(term, other, editDistance);
  final jaccardSimilarity = term.jaccardSimilarity(other, k);
  final lengthDistance = term.lengthDistance(other);
  final lengthSimilarity = term.lengthSimilarity(other);
  final characterSimilarity = term.characterSimilarity(other);
  final startsWithSimilarity = term.startsWithSimilarity(other);
  final similarity = editSimilarity *
      jaccardSimilarity *
      lengthSimilarity *
      characterSimilarity;
  return _TermSimilarityImpl(
      term,
      other,
      similarity,
      lengthDistance,
      lengthSimilarity,
      editDistance,
      editSimilarity,
      jaccardSimilarity,
      characterSimilarity,
      startsWithSimilarity);
