i found link multinomial naive bayes classifier

multinomial naive bayes link

how calculate b' or |v|?

the page said number of terms in vocabulary. in example, how 6 b? counting of term?

"chinese", "beijing", "shanghai", "meacao", "tokyo", "japan"

one more question, if new term appear in testing document? example, in doc 6 appears "bangkok" or new word never appear before. how count probability of new term ?

you right. it's total number of words in vocabulary, since there can 1 entry term in vocabulary.
