ngram_vocab=True ignores single words in vocabulary

[mirorac]

When ngram_vocab=True is used, single words seem to be ignored in the vocabulary. In previous versions, this behavior did not occur, so I wanted to check if this change was intentional or an unintended regression.

Here’s the relevant line in the code:

Top2Vec/top2vec/top2vec.py

Line 890 in 2435731

vocab = phrases

Suggested fix:

vocab += phrases  

Could merging the phrases with the previously built vocabulary resolve the issue, or is this the expected behavior in the latest version?

It was intentional, as single words would often end up as top topic words rather than the ngrams.
