The Ellogon Pattern Engine: Context-free Grammars over Annotations

Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC 2014)

Abstract

This paper presents the pattern engine that is offered by the Ellogon language engineering platform. This pattern engine allows the application of context-free grammars over annotations, which are metadata generated during the processing of documents by natural language tools. In addition, grammar development is aided by a graphical grammar editor, giving grammar authors the capability to test and debug grammars.
