Returns a variety that suggests the best similarity in between the set of trigrams in the 1st string and any continual extent of an requested set of trigrams in the next string. For specifics, begin to see the rationalization under.
Returns a variety that suggests how comparable the two arguments are. The variety of The end result is zero (indicating the two strings are fully dissimilar) to 1 (indicating which the two strings are identical).
very same as word_similarity, but forces extent boundaries to match word boundaries. because we don't have cross-phrase trigrams, this function basically returns finest similarity in between very first string and any steady extent of phrases of the 2nd string.
on the other hand, this purpose isn't going to incorporate padding to the boundaries on the extent. Hence, the quantity of added figures existing in the next string is not regarded, aside from the mismatched phrase boundaries.
