如何使用gensim从受约束的词汇中过滤出语料库中的单词？

Question

I am using gensim for topic modeling. I've created a corpus using

wordDict = corpora.Dictionary(trimmedTextTokens)

gsCorpus = [wordDict.doc2bow(text) for text in trimmedTextTokens]

where trimmedTextTokens are the result of removing stop words. Now I want to filter out the terms from the corpus that are not in a list of a restricted or constructed vocabulary. Any ideas? Thank you!!

Answer 1

Assuming your restricted vocabulary list is in a variable named restrictedVocabularyList you could do:

wordDict = corpora.Dictionary(trimmedTextTokens)

gsCorpus = [wordDict.doc2bow(text) for text in trimmedTextTokens if text in restrictedVocabularyList]
