If the question'What is sentiment analysis?' popped up in your mind as you clicked on this blog, I think you will find my first blog in this series interesting. Essentially, sentiment analysis is a natural language processing technique used to determine the emotional tone of textual data. It is primarily used to understand customer satisfaction, and gauge brand reputation, call center interactions as well as customer feedback and messages. There are various types of sentiment analysis that are common in the real world. In this part of my blog series, let me walk you through the implementation of sentiment analysis.

We are now privy to a spectacular array of communication tools with the potential to connect us all for greater understanding and tolerance. But SA software is counterproductive for open dialog at best, and fundamentally corrosive at worst. It is sure to infuse discord and distrust, much the way the internet is now viewed--isolating us, dividing us into segmented groups--when, at the net's inception, it was supposed to unite the planet. Even more destructive, SA software for SaaS products, like spying on our kids, or when used for marketing to influence elections by insighting ignorant, angry people to elect the second-coming of Hitler, has, and will continue to put even greater distance between us.

The function for the negation handler is available at my Github repo. An example of the function output is shown below. 'Negation' is the main function being called on the tokenized sentence as shown. In the function, whenever a negation word (like'not', "n't", 'non-', 'un-', etc) is encountered, a set of cognitive synonyms called synsets are generated for the word next to the negation. These synsets are interlinked by conceptual semantic and lexical relations to each other in a lexical database called WordNet.

Call Center sentiment analysis is the processing of data by identifying the natural nuance of customer context and analyzing data to make customer service more empathetic. If you are employed in Call Center, the following scenario might be familiar: You get a call from a client and hear their words with stress. The cause for such a cataclysmic reaction: They got a bad rating for their products or business. Some of those reviews might be negative, formal, and neutral. Knowing what someone meant can be tricky unless you understand their emotional quotient.
