PNEPS FOR SHALLOW PARSING - NEPs Extended For Parsing Applied To Shallow Parsing

Emilio del Rosal, Alfonso Ortega de la Puente, Diana Perez-Marin

Abstract

PNEPs (Parsing Networks of Evolutionary Processors) extend NEPs with context free (instead of substituting) rules, leftmost derivation, bad terminals check and indexes to rebuild the derivation tree. It is possible to build a PNEP from any context free grammar without additional constraints, able to generate all the different derivations for ambiguous grammars with a temporal performance bound by the depth of the derivation tree. One of the main difficulties encountered by parsing techniques when building complete parsing trees for natural languages is the spatial and temporal performance of the analysis. Shallow parsing tries to overcome these difficulties. The goal of shallow parsing is to analyze the main components of the sentences (for example, noun groups, verb groups, etc.) rather than complete sentences. The current paper is mainly focused on testing the suitability of PNEPs to shallow parsing.
