Re: AI is an approcah, not an outcome
The quality is very important, a paragraph can be equated to a dictionary definition for all its words.
AI technology first of all is a search for information technology, it appeared as the answer to NIST TREC QA challenge. For example Google searches using the earliest version of AI, which had not AI-parsing technology and couldn't convert paragraphs into dictionary definitions. Thus Google cannot search by sense (that is to structure the paragraphs), and completely rely on popularity.
The quality is essential! The better the paragraph the better it defines all its words' meanings/ create right tuples (where a tuple is a finite ordered list of the paragraph's phrases)
