WebBag-of-words. Bag-of-words (BoW) is a statistical language model used to analyze text and documents based on word count. The model does not account for word order within a document. BoW can be implemented as a Python dictionary with each key set to a word and each value set to the number of times that word appears in a text. WebIn document classification, a bag of words is a sparse vector of occurrence counts of words; that is, a sparse histogram over the vocabulary. In computer vision, a bag of …
