Voz is a system that explores techniques for automatic extraction of narrative information from text. Voz combines off-the-shelf NLP tools, common sense knowledge databases and domain knowledge to extract a symbolic representation of a text and compute features related to narrative information.
Voz implements an NLP pipeline reusing several components from open source, readily available NLP toolkits and knowledge bases. Voz is implemented in Java and Python (preview deployment, old version, unstable). Voz relies on several open source NLP toolkits (Parser Services) made available via a webservice (preview deployment, limited old version) available for download as a turnkey solution for Google App Engine (Webapp2).
For additional information or if you use any component from the system, please cite either of the papers below.
