gensim.utils.dict_from_corpus()¶

gensim.utils.dict_from_corpus(corpus)[source]¶

Scan corpus for all word ids that appear in it, then construct and return a mapping which maps each wordId -> str(wordId).

This function is used whenever words need to be displayed (as opposed to just their ids) but no wordId->word mapping was provided. The resulting mapping only covers words actually used in the corpus, up to the highest wordId found.
