I had a tough evening today trying to convince one of my colleagues that NLP or Natural Language Processing is the super set and Text Analyticsis a sub set of it. At the best probably both are synonymous and can be used interchangeably.
Is that correct? Anybody who has a crystal clarity as to whether these terms have a boundary well defined or can be used interchangeably?
Natural Language Processing is not bound to text only. Consider e.g. speech recognition and processing of speech - or even sign language which is visually communicated.
Simple text analytics may not qualify as natural language processing. E.g. you can use regular expression pattern matching for basic information extraction tasks but that is probably not the kind of linguistics-driven analysis that many people have in mind when thinking of NLP.
