`R/3_1_textSimilarity.R`

`textSimilarity.Rd`

Compute the semantic similarity between two text variables.

`textSimilarity(x, y, method = "cosine")`

- x
Word embeddings from textEmbed.

- y
Word embeddings from textEmbed.

- method
Character string describing type of measure to be computed. Default is "cosine" (see also measures from textDistance() (which here is computed as 1 - textDistance) including "euclidean", "maximum", "manhattan", "canberra", "binary" and "minkowski").

A vector comprising semantic similarity scores.
