Recently, it has been shown by Calladine (1982) and Dickerson (1983) that DNA distortions due to steric clashes between opposing purines and pyrimidines can be quantitated based upon four sum functions. The distortions involve helical twist, roll, torsion angle variations and propeller twist. It is the contention of the authors that these perturbations in structure act as information carriers f...

We describe the SUPERSENSELEARNER system that participated in the English allwords disambiguation task. The system relies on automatically-learned semantic models using collocational features coupled with features extracted from the annotations of coarse-grained semantic categories generated by an HMM tagger.

A collocation is a habitual word combination. Collocational knowledge is essential for many tasks in natural language processing. We present a method for extracting collocations from text corpora. By comparison with the SUSANNE corpus, we show that both high precision and broad coverage can be achieved with our method. Finally, we describe an application of the automatically extracted collocati...

The aim of this study is to examine some aspects of the prosodic system of Central African French, a variety of French spoken by L1 speaker of Sango, an African tone language. On the basis of a comparison of acoustic correlates of syllables involved in clashes in corpora of spontaneous Central African French and Standard French, we argue that the former has a hybrid prosodic system that contain...
