Sentimental analysis tool definition

As the name suggested, a sentiment analysis tool is a piece of software used to analyze people’s feelings. It accesses the intent, tone, and emotion revealing from the text to define whether they are in good or bad moods.

In marketing, a sentiment analysis tool helps marketers understand their audience’s reaction to their brand, products, or services. This tool is aware of how people feel about your business, whether it is positive or negative.

Based on machine learning and natural language processing, sentiment analysis tools are equipped to scan strings of text. It then evaluates the positive and negative connotations and scores the sentiment level of the text. Besides, with just one sentence, sentiment analysis tools can label whether it is positive or negative, regardless of its topics.

For instance, when analyzing the sentence “I love your service, but I’m not a fan of their current ads campaign”, After scanning, this tool analyzes that this sentence can be divided into two parts: the first clause is positive, but the second one is negative. Therefore, the conclusion will be a neutral statement.
