Therefore, we downsampled the tokens of ACWs in the Games Corpus to obtain a balanced data set, with instances of each word and function coming in similar proportions from as many speakers as possible.
we downsampled our data using the following procedure: First, we discarded all word/function pairs with tokens from fewer than four different speakers; second, for each of the remaining word/function pairs, we discarded tokens (at random) from speakers who contributed more than 25% of its tokens.
