Content Analytics API is a component of Azure Machine Learning-powered content examination web administrations. The API may be used to do activities like sentiment analysis and key extraction on unstructured information.
The API returns a numeric score ranging from 0 to 1. Positive emotion is represented by a score near 1, while negative sentiment is represented by a score around 0.
The advantage of this API is that it eliminates the need to design and build a new model; instead, the user only has to supply the data and use the service to obtain the sentiment results.
