Once we name the functionality, we elect a note (such as 'living') as our preliminary context. Then, as soon as contained in the loop, we print the present price of the variable notice, and reset be aware to be the main most probably token in that context (using max()); subsequent time during the loop, we use that observe as our new context. As you'll discover through examining the output, this straightforward method of textual content new release has a tendency to get caught in loops. one other strategy will be to randomly opt for the subsequent note from one of the to be had phrases. instance 2-1. producing random textual content: This application obtains all bigrams from the textual content of the ebook of Genesis, then constructs a conditional frequency distribution to list which phrases are probably to keep on with a given note; e. g. , after the note dwelling, the main most likely be aware is creature; the generate_model() functionality makes use of this information, and a seed notice, to generate random textual content. def generate_model(cfdist, observe, num=15): for i in range(num): print notice, be aware = cfdist[word]. max() textual content = nltk. corpus. genesis. words('english-kjv. txt') bigrams = nltk. bigrams(text) cfd = nltk. ConditionalFreqDist(bigrams) >>> print cfd['living']
