Returns an array of every one of the trigrams while in the offered string. (In exercise This really is seldom valuable apart from debugging.)
Returns a amount that indicates the greatest similarity concerning the list of trigrams in the main string and any constant extent of an purchased set of trigrams in the 2nd string. For information, see the explanation underneath.
Returns a variety that implies how comparable the two arguments are. The array of The end result is zero (indicating that the two strings are absolutely dissimilar) to one (indicating that the two strings are similar).
exact same as word_similarity, but forces extent boundaries to match word boundaries. because we don't have cross-word trigrams, this purpose truly returns biggest similarity amongst to start with string and any steady extent of phrases of the second string.
nonetheless, this perform would not add padding to your boundaries of your extent. Consequently, the quantity of added characters existing in the next string is not regarded, apart from the mismatched term boundaries.
