19 What's in CVC-like things

Natural Language Processing Enabling machines to understand and respond to what people mean, so they can interact with a computer naturally – without having to adapt their behavior to a computer's limitations.
Resolving ambiguities in written and spoken language requires analyzing grammar, concepts, context, and human knowledge. For example:
"The company is ready to sell” is not easy for a computer to understand because the sentence is syntactically ambiguous – is the company opening for business, or does it want to be acquired?
Resolving this ambiguity requires understanding the context: is the sentence in the middle of an article on mergers and acquisitions? Or is the sentence followed by “Its shelves are stocked with all the hot products"? This succeeding sentence is helpful only if the computer understands that the possessive pronoun “its” refers to the company, and that “stocked” and “products” are more relevant to selling goods than to being acquired.
