Abstract

This paper presents the results of an improvement and extension of the Shallow Grammar of Polish, designed for the needs of the Computer-based Methods for Coreference Resolution in Polish Texts (CORE) project. The role of the Grammar was to detect nominal groups (i.e. multi-level nested phrases) that could be considered as mentions in coreference resolution tasks. In this article, the reorganization and changes to the Grammar are described, as well as the results of an evaluation of the Polish Coreference Corpus with manual annotations of mentions and coreferential expressions. A comparison of the second version of the Grammar with an evaluation of the first version reveals an improvement to the recall and F1 measures.
