Efficient generation from packed input

 

Kay (1996) introduces chart generation, a simple and relatively efficient algorithm for generating strings from an unambiguous meaning representation. This paper extends Kay's algorithm to efficiently generate strings from packed meaning representations which encode a large number of meanings in a small amount of data. This is useful when trying to efficiently translate all of the possible meanings of a source sentence into a target language, or when trying to present a user with alternate paraphrases that distinguish the different meanings of a sentence. The new algorithm will typically generate in polynomial time in the size of the packed input when the grammar is context-free, the number of dependencies per semantic variable is bounded, and the disjunctions are relatively independent.
