About

PIKES is a Java-based suite that extracts knowledge from textual resources. The tool implements a rule-based strategy that reinterprets the output of semantic role labelling (SRL) tools in light of other linguistic analyses, such as dependency parsing or co-reference resolution, thus properly capturing and formalizing in RDF important linguistic aspects such as argument nominalization, frame-frame relations, and group entities.

Features

  • Argument nominalization using SRL
  • Frame-frame relations extractions
  • Entity grouping exploiting linking and co-reference
  • Extensible and replaceable NLP pipeline
  • Interlinked three-layer representation model exposed as RDF
  • Instance RDF triples annotated with detailed information of the mentions (via named graph)
  • REST API service included, built on top of Grizzly
  • Based on Java 8 and RDFpro
