Sentiment Analysis Services

Organisations have often found it tricky to accurately figure out what emotions their customers go through when they come in contact with their brand, use their products or experience their services. Now, with multiple online customer interaction platforms, understanding customers’ sentiments has become difficult as well. Sentiment Analysis is also known as opinion mining or emotion AI. It allows you to determine whether the customer’s mood is positive, negative or neutral by analysing their comments or responses on social media platforms, user feedback channels, customer support, chatbots and user reviews platforms. Accurate sentiment analysis generates extremely valuable insights for both businesses and advertisers. These insights or feedback help them formulate better business strategies and take informed business decisions. AI-based sentiment analysing models often find it difficult to ascertain the nuances of human language. Such analysers first need to be trained on high-quality annotated data to accurately analyse sentiments. With a team of highly skilled data annotators and access to a large crowd of data contributors, SunTec.AI is well-positioned to provide quality training data for sentiment analysis services to its clients.
