DipInfo si racconta 2019 Goy et al. 5PRiSMHA: semantic layer - I
General goal: building a "smart digital
archivist" by enhancing the access to
historical archives through Semantic
Web technologies
Semantic layer: semantic metadata describing
the content of historical documents (events,
(
people, places, etc.) by means of:
Computational ontology =
system domain knowledge
RDF triplestore = KB containing
semantic metadata,
based on the
vocabulary provided
by the ontology

HERO − Historical Event Representation Ontology
1. Top/core ontology
◦ is a common vocabulary = shared between:
the system, users of the crowdsourcing platform,
and final users querying the "smart archivist"
computer scientists/ontologists (designing and
implementing the system) and historians
(providing a historical perspective on the docs)
◦ is the result of the integration of
an analysis of existing models
the outcomes of the dialogg between
computer scientists
and historians

HERO-TOP: very general classes and properties
