Babble!

Generate random text based on Stupid Back-off language model.

babble(model, input = NA, n_max = 100L, L = attr(model, "L"))

Arguments

• model: a sbo_predictor object.
• input: a length one character vector. Starting point for babbling! If NA, as by default, a random word is sampled from the model's dictionary.
• n_max: a length one integer. Maximum number of words to generate.
• L: a length one integer. Number of next-word suggestions from which to sample (see details).

Returns

A character vector of length one.

Details

This function generates random text from a Stupid Back-off language model. babble randomly samples one of the top L next word predictions. Text generation stops when an End-Of-Sentence token is encountered, or when the number of generated words exceeds n_max.

Examples

p <- sbo_predictor(twitter_predtable)
set.seed(840) # Set seed for reproducibility
babble(p)
