Sentiment Analysis

Zia Sentiment Analysis is a part of Text Analytics that processes textual content to recognize the tone of the message, and the sentiments conveyed through it. It analyses each sentence in the text to determine if its tone is positive, negative, or neutral. It then determines the tone of the overall text as one of the these three sentiments, based on the sentiments recognized in each sentence.

The response also returns the confidence scores for the sentiments detected in each sentence, to showcase the accuracy of the analysis. The confidence score lies in the range of 0 to 1. A confidence score for the overall analysis is also returned.

You can pass a block of text as the input of upto 1500 characters in a single request. The input text is passed to getSentimentAnalysis().

You can also pass optional keywords for the text. This will enable Sentiment Analysis to process only those sentences that contain these keywords, and determine their sentiments. Other sentences will be ignored.
