Sentiment ClassificationService

sentiment-classification

Lexicon-based sentiment classification of English text (word lists with intensifiers; not a machine-learning model). POST JSON {"text": "..."} to /v1/sentiment; the response is a JSON object with label (positive, negative or neutral), score (-1 to 1), positive_hits, negative_hits and lexicon. Identical input gives identical output on every supplier.
