Approach

Our aim is to evaluate sentiment polarity (Negative/Positive) at several levels of granularity:

  • document (overall sentiment): appropriate for blog posts or technical review articles, estimated whether the author's opinion on the topic is generally positive or negative. Strong polarity means the author is very subjective.
  • paragraph (aspect oriented)
  • entity (very specific target)

Pipeline for document sentiment:
