Machine learning for marketing (briefly) explained
Machine learning machine learning (ML) is helping humans solve problems in a more efficient way.
Text and sentiment analysis are two related methods that are useful for marketers.
Here’s a quick definition for each:
What is text analysis?
A big portion of the internet is
cat pictures text content. Everything from instant messages, blog comments, articles, reddit posts and so on.
Text analysis takes those texts and allows you to automatically extract and classify information from text content.
Anything text based can be analyzed. Things like tweets, emails, support tickets, product reviews, and survey responses and more to provide information like keywords, geographical information, SEO statistics or sentiment.
What is sentiment analysis?
Sentiment analysis is a more advanced form of text analysis API.It is the interpretation and classification of emotions (positive, negative and neutral) in text..
Using sentiment analysis allows you to identify customer sentiment (feelings) toward products, brands or services by taking their online conversations and feedback.
Instead of just looking for things like keyword topics, sentiment analysis goes a little deeper and is able to tell you exactly how users may feel towards a thing.
