The system integrates an NLP pipeline, a keyphrase extractor and an entity linking module. On the basis of results from those components, the system extracts propositions relating an actor and an actor's negotiation point, using rules and a model with actors and predicates.
While the output of the rules and model were evaluated in the paper, evaluation results for the basic NLP pipeline were omitted, for space reasons. For convenience, at the links below, we reproduce evaluation results for the pipeline's modules, as available from the literature.
As for the evaluation for the analysis rules to extract propositions, reported on in the paper, the manually created reference set and information about its creation are also accessible from the links below.
