Tool/System Report
This paper describes a toolset to transform a legal decision in English language into a collection of events represented in RDF supported by an ontology. Two different sources for judgments have been used for demonstration: the European Court of Human Rights (ECHR) and the European Court of Justice (ECJ). Text documents, preferably structured, go through a pipeline where they are analyzed, annotated and finally ingested in a triple store that can be queried through an open SPARQL endpoint. A translation service permits transforming time related information from/to different formats. The related ontology is publicly available online, the source code is accesible in an open modality and a web portal demonstrates the toolset. The adoption of standards and the service-oriented architecture favor the interoperability and extensibility of this framework respectively. A set of predefined queries facilities retrieving information from the knowledge graph.
