Why are consumer sentiments important for your search engine rankings? Bing has already done it. They use sentiment analysis for featured snippets and obviously how can Google be left behind?
No one likes negativity even if its online. Don’t worry, I’m not here to give you a self-help guide on spreading positivity, but emphasize that in a digitally driven world, the sentiments (positive or negative) of your consumers are extremely important. Can you imagine that MIT has developed a sentiment algorithm that can analyze sarcasm that is implied when emojis are used. Imagine being able to capture all the reviews about your product or service and being able to know how your consumers feel about what you have to offer.
As per Wikipedia, Opinion mining (sometimes known as sentiment analysis or emotion AI) refers to the use of natural language processing, text analysis, computational linguistics, and biometrics to systematically identify, extract, quantify, and study affective states and subjective information.
