Positive and Negative list

Is there a sentiment words list? It will be more useful if the words are classified into the sub sentiment values (-ve, +ve, very +ve, very -ve, etc)?

Hi @ahmed_gomaa -

In some of the example workflows (like this one, which uses a lexicon based approach), we use positive and negative sentiment words from the MPQA Corpus (https://mpqa.cs.pitt.edu/corpora/mpqa_corpus/). But this is not built into a node by default.

Yes, I note that from the labs. So, I should build my own list for each one of them, shouldn’t I?

Why isn’t there a built-in list for that type of tagging like as the POS tagging, NE tagging, or stop word filter?

As for why, I’m not exactly sure. If that would be useful for you, we could consider implementing something like a Sentiment Assignment node.

(Note that we recently released the Amazon Comprehend node, which uses an external Amazon service to classify text according to sentiment.)
