Calculate the sum vector of multiple words.

Description

Calculate the sum vector of multiple words.

Usage

sum_wordvec(data, x = NULL, verbose = TRUE)

Arguments

data

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

x

Can be:

• NULL: use the sum of all word vectors in data

• a single word:

  "China"

• a list of words:

  c("king", "queen")

  cc(" king , queen ; man | woman")

• an R formula (~ xxx) specifying words that positively and negatively contribute to the similarity (for word analogy):
