Parsing paradigms based on context free grammars fail to resolve problems like inefficient reparsing of trees, left-recursive rules and ambiguity in context. Probabilistic natural language processing methods aim
325 strained model. The results on English parsing rather suggest that it is the similarity in degrees of freedom (e.g., INHERIT with L=3x3x3 and PCFGLA with L=2x2) that produces comparable results...
