textDistanceMatrix {text} | R Documentation |
Compute semantic distance scores between all combinations in a word embedding
Description
Compute semantic distance scores between all combinations in a word embedding
Usage
textDistanceMatrix(x, method = "euclidean", center = FALSE, scale = FALSE)
Arguments
x |
Word embeddings (from textEmbed). |
method |
(character) Character string describing type of measure to be computed; default is "euclidean" (see also measures from stats:dist() including "maximum", "manhattan", "canberra", "binary" and "minkowski". It is also possible to use "cosine", which computes the cosine distance (i.e., 1 - cosine(x, y)). |
center |
(boolean; from base::scale) If center is TRUE then centering is done by subtracting the embedding mean (omitting NAs) of x from each of its dimension, and if center is FALSE, no centering is done. |
scale |
(boolean; from base::scale) If scale is TRUE then scaling is done by dividing the (centered) embedding dimensions by the standard deviation of the embedding if center is TRUE, and the root mean square otherwise. |
Value
A matrix of semantic distance scores
