There are some ‘BASIC’ methods in text analysis and then there are some ’ADVANCED’ ones!
But first, “Get your BASICs right” (lol! No, not needed :P) You can directly jump to reading the Advanced techniques (link at the end of the page) (but, don’t skep THEM!)
The number of times certain words or concepts occur in a text. Simply speaking, it helps you to identify the popular words or expressions used in any sort of conversation.

Now, all those human conversations that you can avail in the form of text including those which can convert from speech-to-text, can be processed by a machine to extract relevant insights.
Wait, what about Gestures? — No!
Pet’s Bow-wow? — No No!!
Text analysis is Natural Language processing (NLP) that processes unstructured text(s) to automatically extract and classify relevant information out of them using different techniques such as Topic extraction, Sentiment analysis, Aspect classification, Named entity extraction, and more. These texts could have been generated in different sources such as survey responses, emails, product reviews, tweets, support tickets, etc. …
Have heard enough about the London Bridge, the Buckingham Palace, Queen, Prince and Princess… but have you ever been to Shanghai !?
If you have a day to spare for a tour, China has immense to offer and Shanghai is definitely a place worth a visit.
