pair_similarity {PsychWordVec}

Compute a matrix of cosine similarity/distance of word pairs.

Description

Compute a matrix of cosine similarity/distance of word pairs.

Usage

pair_similarity(
  data,
  words = NULL,
  pattern = NULL,
  words1 = NULL,
  words2 = NULL,
  distance = FALSE
)

Arguments

data

A wordvec (data.table) or embed (matrix), see data_wordvec_load.

words

[Option 1] Character string(s).

pattern

[Option 2] Regular expression (see str_subset). If neither words nor pattern are specified (i.e., both are NULL), then all words in the data will be extracted.

words1, words2

[Option 3] Two sets of words for only n1 * n2 word pairs. See examples.

distance

Compute cosine distance instead? Defaults to FALSE (cosine similarity).

Value

A matrix of pairwise cosine similarity/distance.
