10. A non-transitory computer readable storage medium containing a program in a non-transitory form that when executed in a computer system causes the system to create and use artificial intelligence (AI) clones of respective multiple entities in a computer-implemented process comprising: for each of the multiple AI clones, receiving respective text into the computer system from one or more sources; for each of the multiple AI clones, obtaining respective paragraphs from the text received for the AI clones; at least some of the paragraphs comprising multiple sentences, and at least some of the sentences comprising multiple clauses identified based upon figures of speech and punctuation; obtaining a first set of respective context phrases from the received paragraphs, which context phrases are obtained from the respective clauses and are indicative of the context of the respective paragraphs; obtaining respective weights of the context phrases using parameters related to frequency of occurrence of a context phrase relative to other context phrases or to absolute number of occurrences of a context phrase therein; storing the context phrases and the paragraphs as structured data in one or more tables to thereby create initial respective multiple AI clones; for multiple initial AI clones, improving the AI clones by adding paragraphs and a second set of context phrases from text subsequently supplied to the computer system by the source of the text that was used to create the initial AI clones and from one or more other sources, including one or more instructors, and by selectively deleting data from the one or more tables, to thereby create respective improved AI clones; and using the improved AI clones and any remaining initial AI clones that have not been improved, to answer questions posed by users through a process comprising using a compatibility test matching context phrases related to the respective questions to context phrases related to AI clones through a compatibility algorithm relating weights of context phrases related to a question and weights of context phrases related to AI clones, and to direct advertisements to AI clones, wherein a single advertisement is directed essentially concurrently to multiple AI clones, using for the purpose a matching algorithm that uses selected matching criteria in comparing context phrases obtained from the questions or advertisements with said structured data in said one or more tables, which matching algorithm relates context phrases related to advertisements to context phrases related to AI clones and takes into account respective weights of the context phrases that the matching algorithm relates; wherein the AI clones are configured to replace human sources of information in answering a user's question and assist advertisers in selecting plural AI clones that are likely to be receptive to a single advertisement to thereby direct the advertisement only to some of the AI clones, based on the content of the question and the advertisement.
