# the sentence "Squealing suitcase squids are not like regular squids." could be changed into the following BoW dictionary:
{'squeal': 1, 'like': 1, 'not': 1, 'suitcase': 1, 'be': 1, 'regular': 1, 'squid': 2}
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.
