Natural language understanding is a subtopic of natural language processing in artificial intelligence that deals with machine reading comprehension.
The process of disassembling and parsing input is more complex than the reverse process of assembling output in natural language generation because of the occurrence of unknown and unexpected features in the input and the need to determine the appropriate syntactic and semantic schemes to apply to it, factors which are pre-determined when outputting language.
There is considerable commercial interest in the field because of its application to news-gathering, text categorization, voice-activation, archiving and large-scale content-analysis.

Famous quotes containing the words natural and/or language:
“The great man knew not that he was great. It took a century or two for that fact to appear. What he did, he did because he must; it was the most natural thing in the world, and grew out of the circumstances of the moment. But now, every thing he did, even to the lifting of his finger or the eating of bread, looks large, all-related, and is called an institution.”
—Ralph Waldo Emerson (1803–1882)
“Neither Aristotelian nor Russellian rules give the exact logic of any expression of ordinary language; for ordinary language has no exact logic.”
—Sir Peter Frederick Strawson (b. 1919)
