The SentiLecto API provides NLU (natural language understanding) services for Spanish and Portuguese texts, including methods for sentiment analysis, deep structure analysis, entity extraction, and fact mining. The sentiment analysis feature is relatively unique in that it can handle polarity shifting in the same sentence, within embedded clauses, or even on the same word.
SentiLecto better represents the premise whereby the entities involved in the opinion are syntactically mapped onto SVO (subject-verb-object) slots for their sentiment assignments: 'Mary hates John' (two entities but only the direct object has a negative presentation) vs. 'Mary defames John' (the same two entities but only the subject has negative presentation).
