... 3There are also backward rules (<) that are analogous to forward rules (>). Crossing rules where zt is found in the direction opposite of that of y are labelled with 'x'. ... edu Abstract This paper shows that a class of Combinatory Categorial Grammars (CCGs) augmented with a linguistically-motivated form of type raising involving variables is weakly equivalen...

... in the dataset. With POS tags we achieve an F-score of , but with supertags we only achieve an F-score of . This is not sur- prising becuase Srinivas’ supertag was only trained with a trigram ... 20. There is a small problem with the supertag set that we have been using, as far as NP chunking is con- cerned. Two words with different POS tags may be tagged with the same supertag. F...

... hydrogen bond with O2 of C@O2 of Arg-AMP (Fig. 7B), and the sp 2 hybrid orbital on the C therefore changes to an sp 3 hybrid orbital. The C with an sp 3 hybrid orbital has the ability to react with NH 2 OH. ... Arg- AMP reacts with NH 2 OH rather than with tRNA shows that, in the ATP–PP i exchange reaction, tRNA stays preferentially in the position suitable for the formation of a hy...
