Computing Weighted Jaccard Distance — wgt_jaccard

#' wgt_jaccard_distance computes the Weighted Jaccard Distance between two strings. It is vectorized, and accepts only two equal-length string vectors.

wgt_jaccard_distance(string_1, string_2, corpus, nthreads = 1)

Arguments

string_1: character vector
string_2: character vector
corpus: corpus data.table, constructed with fedmatch::build_corpus
nthreads: number of threads to use in the underlying C++ code

Value

numeric vector with the Weighted Jaccard distances for each element of string_1 and string_2.

Details

See the vignette fuzzy_matching for details on how the Weighted Jaccard similarity is computed.
