Learn how to run a sentiment analysis in under two minutes with GYANA, the no-code data science notebook!
Sentiment analysis is the stuff a marketer’s dreams are made of. Gauging sentiment is valuable for any organisation looking to understand the public opinion of a product, event, brand, entity, or person.
At its core, sentiment analysis tells us how people feel about something. It studies the subjective information within a piece of writing, classifying each expression as positive, negative, or neutral.
Organisations can then take their findings and made decisions based on the insight, to shape its output, tailor a product, or refine an identity to reach the desired result.
Normally, running sentiment analysis on a particular data set has been a long-winded, complicated affair.
It’s traditionally been a process reserved for skilled data scientists, given that it requires complex programming languages and an understanding of Natural Language Processing (NLP).
Not anymore! It’s so simple with VAYU that we ran one in under two minutes.
