in this paper, we develop two piecewise polynomial methods for the numerical evaluation of cauchy principal value integrals of oscillatory kind. the two piecewisepolynomial quadratures are compact, easy to implement, and are numerically stable. two numerical examples are presented to illustrate the two rules developed, the convergence of the two schemes is proved and some error bounds obtained,

We describe extensions to a scheme for evaluating parse selection accuracy based on named grammatical relations between lemmatised lexical heads. The scheme is intended to directly reflect the task of recovering grammatical and logical relations, rather than more arbitrary details of tree topology. There is a manually annotated test suite of 500 sentences which has been used by several groups t...
