... AN EXTENDED LR PARSING ALGORITHM FOR GRAMMARS USING FEATURE-BASED SYNTACTIC CATEGORIES Tsuneko Nakazawa Beckman Institute for Advanced Science and Technology ... tsuneko@grice.cogsci.uiuc.edu ABSTRACT This paper proposes an LR parsing algorithm modified for grammars with feature-based categories. The proposed algorithm does not instantiate categories...

... elimination algorithm: REDUNDANCY-ELIMINATION(Ch, R) 1 for each split S in Ch 2 do if S is eliminable with respect to R 3 then remove S from Ch Prop. 3 shows that the algorithm is a correct algorithm for ... reduc- tion factor for an individual USR is 666.240. We also measured the ratio of USRs for which the algorithm achieves complete reduction (Fig. 6): The algorithm is co...

... alternative LR algorithm for TAGs Mark-Jan Nederhof DFKI Stuhlsatzenhausweg 3 D-66123 Saarbr/icken, Germany E-marl: nederhof@dfki.de Abstract We present a new LR algorithm for tree- adjoining grammars. ... alternative to an existing algorithm that is shown to be incorrect. Furthermore, the new algorithm is much sim- pler, being very close to traditional LR parsi...

... HTH functions could be performed by both isoforms, although for antenna development only full-length HTH was sufficient. It may therefore be that Meis2e- like proteins are functional for some activities, ... represents a naturally occurring dominant negative form of Meis2 that might be able to interfere by competing with other Meis isoforms for binding to Pbx1, for example. Our attempt...
