Function lnt_similarity [LexisNexisTools v0.3.3]
keywords
similarity
title
Check for highly similar articles.
description
Check for highly similar articles by comparing all articles published on the same date. This function implements two measures to test if articles are almost identical. The function textstat_simil, which compares the word similarity of two given texts; and a relative modification of the generalized Levenshtein (edit) distance implementation in stringdist. The relative distance is calculated by dividing the string distance by the number of characters in the longer article (resulting in a minimum of 0 if articles are exactly alike and 1 if strings are completely different). Using both methods cancels out the disadvantages of each method: the similarity measure is fast but does not take the word order into account. Two widely different texts could, therefore, be identified as the same, if they employ the exact same vocabulary for some reason. The generalized Levenshtein distance is more accurate but is very computationally demanding, especially if more than two texts are compared at once.
