The objective of PRiSMHA (Providing Rich Semantic Metadata for Historical Archives) is to demonstrate how a rich semantic representation of the content of historical archival resources can both:

  • provide a significant enhancement in the possibilities of exploitation of archival resources;
  • be sustainable, as far as the overload imposed by knowledge acquisition (and the consequent bottleneck in the process) is concerned.

A rich semantic representation means a formal representation based on established standards (e.g., OWL, RDF, Linked Open Data), grounded in well-founded reference ontologies (e.g., DOLCE), and supporting the detailed representation of historical events, including their location, temporal information, how the involved entities participate in them, and relations among events themselves.

Such a representation will be designed in collaboration with historians involved in the project, providing the needed domain expertise.

The sustainability of the approach will rely on a crowdsourcing collaborative model, where both experts and trusted users (e.g., students) will participate in the semantic annotation process. In particular, the interaction model will be driven by the underlying ontologies and will be supported with suggestions provided by automatic information extraction techniques.

PRiSMHA is based on a close collaboration with the Polo del '900, a cultural center, headquartered in Torino, co-funded by Compagnia di San Paolo, Comune di Torino and Regione Piemonte. It involves twelve cultural and historical institutions - engaged in research and cultural initiatives about the 20th Century social, economic and political issues in Piemonte, and hosting an extremely rich set of documentary repositories. Besides the mentioned archives, the historical building hosting the Polo del '900 includes a museum, a permanent exhibition, a library, a conference hall and three learning rooms.

In particular, PRiSMHA will mainly rely on resources from the archives and library of the Istituto Piemontese Antonio Gramsci, which - with its 2.5 km of documents - represents the major "contributor" (25%) of the Polo del '900 archives.

The domain selected for the proof-of-concept prototype is represented by documents from the Istituto Gramsci archives, concerning the students and workers protest during the years 1968-1969 in Italy.
