Sentiment analysis, or opinion mining, is a technique used in natural language processing (NLP) to identify the sentiment or emotional tone expressed in a piece of text, including tweets, customer reviews, and news articles.
The Sentiment Analysis API accepts text as input and provides an analysis of the sentiment in the output. The API uses machine learning algorithms and linguistic analysis to classify the sentiment as positive, negative, or neutral. Some sophisticated APIs are capable of providing sentiment intensity scores or fine-grained sentiment analysis, which capture subtle nuances in expressed emotions.
For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of the best Sentiment Analysis Open Source Models:
