For example, for product reviews of a laptop you might be interested in processor speed. An aspect-based algorithm can be used to determine whether a sentence is negative, positive or neutral when it talks about processor speed. Fine-grained sentiment analysis focuses on identifying the polarity of the opinion. Or it can be taken to a heightened level of specificity through identifiers such as very good, good, neutral, bad, very bad. Lexicon-based sentiment analysis is an easy approach to implement and can be customized without much effort. The formula for calculating sentiment scores could, for example, be adjusted to include frequencies of neutral words and then verified to see if this has a positive impact on performance.

Sentiment analysis solutions apply consistent criteria to generate more accurate insights. For example, a machine learning model can be trained to recognise that there are two aspects with two different sentiments. It would average the overall sentiment as neutral, but also keep track of the details. Fine-grained sentiment analysis provides a more precise level of polarity by breaking it down into further categories, usually very positive to very negative.
For example, if a product reviewer writes “I can’t not buy another Apple Mac” they are stating a positive intention. Machines need to be trained to recognize that two negatives in a sentence cancel out. With irony and sarcasm people use positive words to describe negative experiences. It can be tough for machines to understand the sentiment here without knowledge of what people expect from airlines. In the example above words like ‘considerate” and “magnificent” would be classified as positive in sentiment. But for a human it’s obvious that the overall sentiment is negative.
We periodically train new versions of the sentiment analysis solution as new high-quality data appears. This means that our model’s efficiency constantly increases over time. With this in place, learning begins sentiment analysis definition and continues as a semi-automatic process.
