This paper reports some experiments that com- pare the accuracy and performance of two stochastic parsing systems. The currently pop- ular Collins parser is a shallow parser whose output contains more detailed semantically- relevant information than other such parsers. The XLE parser is a deep-parsing system that couples a Lexical Functional Grammar to a log- linear disambiguation component and provides much richer representations theory. We mea- sured the accuracy of both systems against a gold standard of the PARC 700 dependency bank, and also measured their processing times.
