Natural Language Generation
Natural Language Generation (NLG) is the natural language processing task of generating natural language from a machine representation system such as a knowledge base or a logical form. Psycholinguists prefer the term language production when such formal representations are interpreted as models for mental representations.
It could be said an NLG system is like a translator that converts a computer based representation into a natural language representation. However, the methods to produce the final language are different from those of a compiler due to the inherent expressivity of natural languages.
NLG may be viewed as the opposite of natural language understanding: whereas in natural language understanding the system needs to disambiguate the input sentence to produce the machine representation language, in NLG the system needs to make decisions about how to put a concept into words.
Simple examples are systems that generate form letters. These do not typically involve grammar rules, but may generate a letter to a consumer, e.g. stating that a credit card spending limit was reached. More complex NLG systems dynamically create texts to meet a communicative goal. As in other areas of natural language processing, this can be done using either explicit models of language (e.g., grammars) and the domain, or using statistical models derived by analysing human-written texts.

Famous quotes containing the words natural, language and/or generation:
“If we have come to think that the nursery and the kitchen are the natural sphere of a woman, we have done so exactly as English children come to think that a cage is the natural sphere of a parrot: because they have never seen one anywhere else.”
—George Bernard Shaw (1856–1950)
“There is no such thing as an ugly language. Today I hear every language as if it were the only one, and when I hear of one that is dying, it overwhelms me as though it were the death of the earth.”
—Elias Canetti (b. 1905)
“Generation after generation of women have pledged to raise their daughters differently, only to find that their daughters grow up and fervently pledge the same thing.”
—Elizabeth Debold (20th century)
