, , indicating that the vocabulary contains , entries againthe data is stored as scipy sparse matrix let' look at the vocabulary in bit more detail another way to access the vocabulary is using the get_feature_name method of the vectorizerwhich returns convenient list where each entry corresponds to one featurein[ ]feature_names vect get_feature_names(print("number of features{}format(len(feature_names))print("first features:\ {}format(feature_names[: ])print("features to :\ {}format(feature_names[ : ])print("every th feature:\ {}format(feature_names[:: ])out[ ]number of features first features[' '' '' '' '' '' '' '' '' '' '' '' '' '' '' am'' pm'' '' '' pm'' 'features to ['dratted''draub''draught''draughts''draughtswoman''draw''drawback''drawbacks''drawer''drawers''drawing''drawings''drawl''drawled''drawling''drawn''draws''draza''dre''drea'every th feature[' ''aesir''aquarian''barking''blustering''bete''chicanery''condensing''cunning''detox''draper''enshrined''favorit''freezer''goldman''hasan''huitieme''intelligible''kantrowitz''lawful''maars''megalunged''mostey''norrland''padilla''pincher''promisingly''receptionist''rivals''schnaas''shunning''sparse''subset''temptations''treatises''unproven''walkman''xylophonist'as you can seepossibly bit surprisinglythe first entries in the vocabulary are all numbers all these numbers appear somewhere in the reviewsand are therefore extracted as words most of these numbers don' have any immediate semantic meaning--apart from " "which in the particular context of movies is likely to refer to the james bond character weeding out the meaningful from the nonmeaningful "wordsis sometimes tricky looking further along in the vocabularywe find collection of english words starting with "drayou might notice that for "draught""drawback"and "drawerboth the singular and plural forms are contained in the vocabulary as distinct words these words have very closely related semantic meaningsand counting them as different wordscorresponding to different featuresmight not be ideal quick analysis of the data confirms that this is indeed the case try confirming it yourself representing text data as bag of words
