Sentiment Detection in the World of AI
Sentiment detection and analysis is difficult without AI tools and algorithms. For example, the phrase “the battery life is too short” does not by itself indicate positive or negative emotion. In context and through human understanding, it is easy to understand that this is negative, however.
With over 80% of the world’s data in an unstructured form, analyzing the information by hand is an impossible task. By using AI systems, however, the task becomes more straightforward. AI algorithms can tag and label this unstructured data so that companies and businesses understand what actions they need to take.
Sentiment detection and analysis is not easy, though. Human languages are complex and have their own rules with unique grammar structures and cultural connotations that need to be accounted for. For example, the sentence: “I lost the game. Amazing!” could to a machine sound like a positive statement. However, you or I read the phrase understand the sarcastic connotations and tone. The word “Amazing” by itself is generally positive, but in context, the sentence is actually negative.
