Bernard LANG INRIA B.P. 105, 78153 Le Chesnay, France lang@inria.inria.fr The intent of this presentation is to exhibit the commonalities between the following syntactic problems: 1. parsing ambiguous or incomplete input, often known as word lattice parsing; 2. parsing illformed input, i.e. input that does not belong to the language formally defined by a grammar; 3. syntactic disambiguation of ambiguous sentences; 4. accounting for deviant syntactic structures in grammatical language descriptions. The key idea behind this work is that of a weighted grammar. For simplicity we consider here only a special case of the more general definition given in [Teitelbaum 73], which could lead to other interesting variations (e.g. probabilities as weights, using multiplication instead of addition as below). We define a weighted grammar as a ContextFree (CF) grammar with a numeric weight attached to each of its rules. We attach to any derivation tree a weight that is the sum of the weights of a...
