Data-oriented parsing
Appearance
Data-oriented parsing (DOP, also data-oriented processing) is a probabilistic grammar formalism in computational linguistics. DOP was invented by Remko Scha in 1990 with the aim of developing a performance-oriented grammar framework. Unlike other probabilistic formalisms, DOP takes into account all subtrees contained in a treebank rather than being restricted to, for example, 2-level subtrees (like PCFGs).
Several variants of DOP have been developed. The initial version was based on tree-adjoining grammar (TAG), while more recently, DOP has been combined with lexical-functional grammar (LFG). The resulting DOP-LFG finds an application in machine translation.[1]
