Who cares about sentiment analysis?

In this ever increasing technological robotic world we live in then you really should give two hoots about sentiment analysis!

So what is sentiment analysis when it’s a home?

According to Wikipedia…

Sentiment analysis (also known as opinion mining) refers to the use of natural language processing, text analysis and computational linguistics to identify and extract subjective information in source materials. Sentiment analysis is widely applied to reviews and social media for a variety of applications, ranging from marketing to customer service.

Generally speaking, sentiment analysis aims to determine the attitude of a speaker or a writer with respect to some topic or the overall contextual polarity of a document. The attitude may be his or her judgment or evaluation (see appraisal theory), affective state (that is to say, the emotional state of the author when writing), or the intended emotional communication (that is to say, the emotional effect the author wishes to have on the reader).

So can you game this or is that not very sentimental?

Will systems pick up on the fact that you’re a fraud trying to devalue a corporate brand, political career or personal reputation?

Probably… the newspapers do it all the time to us human beings, thinking we’re stupid enough to believe their every word… but let’s focus on the happy side for now and see what’s being said out there in the ether…
