Positive sentiment

The biggest use case of sentiment analysis in industry today is in call centers, analyzing customer communications and call transcripts. This approach restricts you to manually defined words, and it is unlikely that every possible word for each sentiment will be thought of and added to the dictionary. Instead of calculating only words selected by domain experts, we can calculate the occurrences of every word that we have in our language (or every word that occurs at least once in all of our data). This will cause our vectors to be much longer, but we can be sure that we will not miss any word that is important for prediction of sentiment. Before analyzing the text, some preprocessing steps usually need to be performed.

However, rule-based approaches are limited to the specific rules that are defined, and may not be able to handle complex data or new cases that are not covered by the rules. It can be difficult to anticipate and account for all the different ways that people express sentiment in a natural language only using rules. Acquiring an existing software as a service (SaaS) sentiment analysis tool requires less initial investment and allows businesses to deploy a pre-trained machine learning model rather than create one from scratch.
