Fluid Construction Grammar
Fluid construction grammar (FCG) is a computational construction grammar formalism that allows computational linguists to formally write down the inventory of lexical and grammatical constructions as well as to do experiments in language learning and language evolution. FCG wants to be an open instrument that can be used by construction grammarians who want to formulate their intuitions and data in a precise way and who want to test the implications of their grammar designs for language parsing, production and learning.
FCG integrates many notions from contemporary computational linguistics such as feature structure and unification-based language processing. Rules are considered bi-directional and hence usable both for parsing and production. Processing is flexible in the sense that it can even cope with partially ungrammatical or incomplete sentences. FCG is called 'fluid' because it acknowledges the premise that language users constantly change and update their grammars. The research on FCG is headed by Luc Steels whose team is working at the VUB AI Lab in Brussels and the Sony Computer Science Lab in Paris.

Famous quotes containing the words fluid, construction and/or grammar:
“In place of a world, there is a city, a point, in which the whole life of broad regions is collecting while the rest dries up. In place of a type-true people, born of and grown on the soil, there is a new sort of nomad, cohering unstably in fluid masses, the parasitical city dweller, traditionless, utterly matter-of-fact, religionless, clever, unfruitful, deeply contemptuous of the countryman and especially that highest form of countryman, the country gentleman.”
—Oswald Spengler (1880–1936)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“Literary gentlemen, editors, and critics think that they know how to write, because they have studied grammar and rhetoric; but they are egregiously mistaken. The art of composition is as simple as the discharge of a bullet from a rifle, and its masterpieces imply an infinitely greater force behind them.”
—Henry David Thoreau (1817–1862)
