vc_leven: VC-sensitive edit distance for Dialectometry

In dialectR: Doing Dialectometry in R

Description

An edit distance that is sensitive to vowel and consonant alignment. If the aligned segments are a vowel-consonant pair, the difference is penalized as a score of 2; if not, 1. Allows for normalization by dividing alignment length, and for accommodating multiple responses with Bilbao distance, as proposed by Aurrekoetxea et al (2020).

Usage

vc_leven(vec1, vec2, alignment_normalization = FALSE, delim = NULL)

Arguments

vec1	A vector of words.
vec2	A vector of words to be compared against.
alignment_normalization	A logical value, indicating whether or not the difference scores are to be normalized by alignment length.
delim	An optional delimiter, in situations where multiple responses exist in the data.

Value

A number indicating the number of operations to transform a string to the other, which optionally may undergo length normalization.
