most_similar: Calculate the words most similar to an input word.

In ajfabry/Statspeare: What the Package Does (One Line, Title Case)

Description

The similarity between two vectors is determined as follows:

cos(x,y) = (a • b) / (||a|| ||b||)

where (a • b) is equal to the dot product of a and b, and (||a|| ||b||) is equal to the magnitude of a and b. This formula returns the angle between the two vectors.

Usage

most_similar(m, word, num_results = 10)

Arguments

m	A matrix.
word	An entry in m.
num_results	Number of results to display.

Value

A data table of words in m most similar to x.
