Events Extractor for Polish Based on Semantics-Driven Extraction Templates

摘要

The paper presents a certain paradigm of extracting events from Polish free texts. We call it semantics-driven because the extraction templates are generated from the specification of a domain knowledge that is expressed in the form of a well-founded ontology. The considered method is equipped with the supporting tool that has two components: the first one is domain-dependent and serves to generate extraction templates on the basis of an ontology. The second part is linguistic and domain-independent and may be used whenever templates are supplied, not necessarily via the generator. We checked the quality performance of our generator on a basis of a case study.
