Embedding Coherence Test

Description

This function estimate the Embedding Coherence Test (ECT) of word embeddings (Dev & Philips, 2019). If possible, please use query() instead.

Usage

ect(w, S_words, A_words, B_words, verbose = FALSE)

Arguments

w	a numeric matrix of word embeddings, e.g. from read_word2vec()
S_words	a character vector of the first set of target words. In an example of studying gender stereotype, it can include occupations such as programmer, engineer, scientists...
A_words	a character vector of the first set of attribute words. In an example of studying gender stereotype, it can include words such as man, male, he, his.
B_words	a character vector of the second set of attribute words. In an example of studying gender stereotype, it can include words such as woman, female, she, her.
verbose	logical, whether to display information

Value

A list with class "ect" containing the following components:

• ⁠$A_words⁠ the input A_words

• ⁠$B_words⁠ the input B_words

• ⁠$S_words⁠ the input S_words

• ⁠$u_a⁠ Cosine similarity between each word vector of S_words and average vector of A_words

• ⁠$u_b⁠ Cosine similarity between each word vector of S_words and average vector of B_words
