... Likelihood approach to grammatical analysis, and CLAWS in particular, can be used to analyse text including ill-formed syntax. More importantly, it can also be adapted to flag syntactic errors ... the best tag for each word, as before, and then measuring ABSOLUTE LIKELIHOODS of tag- pairs. Instead of a separate tag-pair error likelihood table to assess the grammaticality, t...

... The match between a boundary and a document break was accepted if the boundary was no fur- ther than 9 words (after pre-processing). Globally, our results are not as good as Hearst's ... slowly. The decrease actually becomes significant only when Nb becomes larger than N. It means that the weights associated to the boundaries are not very significant. We have validated th...

... tech- nique has been presented as a way to derive automata from certain bilinear grammars. We found that the Earley algorithm is intimately re- lated to an automaton that simulates non-deterministic ... original grammar. For many grammars, however, the number of LR(0)-states, may be considerably smaller than the number of items. This seems to be the case for the nat- ural...
