SemanAc IntegraAon experiments Improving Interoperability and Reusability
Unlocking the PotenAal of Digital Archaeological Data Florence, 15 December 2016
Maria Theodoridou FORTH-‐ICS, Greece
The challenge Build an Integrated Knowledge Repository and support innovaAve reasoning on archaeological datasets (relaAng and combining data) preserving the original meaning and the perspecAve of the different data providers. Two main pillars: Ø a global, extensible schema in the form of a formal ontology that allows for
integraAon without loss of meaning.
Ø ARIADNE Reference Model = CIDOC CRM + Extension Suite
Ø Common vocabularies/terminologies Ø Use of well established standard terminologies Ø GeCy AAT Ø Nomisma.org
ARIADNE Reference Model
Few concepts, high recall
Special concepts, high precision
Case Studies Ø NumismaAcs
• tradiAonal science with experience and iniAaAves in standardizaAon so it was chosen as a very good starAng point for item-‐level integraAon
• Nomisma.org serves as a authoritaAve resource
Ø Wood/Dendrochronology • integraAon of informaAon from diverse datasets and (via NLP)
archaeological reports in different languages • GeCy AAT serves as an authoritaAve resource
Ø Sculptures • data integraAon of sources from various disciplines including sculpture informaAon and its archaeological context.
• focuses on the provenance of informaAon according to bibliographic references which leads to advanced literature research
NumismaAcs Case Study Extracts of 5 diverse databases & datasets: Ø OEAW: dFMRO coin archive 72 records
Ø COINS Project: SAR Archive 627 records
Ø COINS Project: FWM Archive
Ø iDAI Coins Pergamon 517 records
Ø CultureItalia: MuseiD-‐Italia 25562 records
Ø NLP data from Heslington East ExcavaAon Archive 37 records
Ø ACDM records
NumismaAcs Case Study
Wood/Dendrochronology Case Study • Extracts of 5 archaeological datasets, output from NLP
on 25 grey literature reports • MulAlingual -‐ English, Dutch and Swedish data • Data integraAon via CIDOC CRM and Geay AAT • 1.09 million RDF triples • 23,594 records • 37,935 objects • DemonstraAon query builder
for easier cross-‐search and browse of integrated datasets

Ø NumismaAcs Case Sudy 1,2M triples Ø Wood/Dendrochronology Case Study 1,5M triples Ø Sculptures Case Study 5,5 M triples Ø AAT thesaurus 4,4M triples
Total ~ 13M triples Contains different levels of informaAon:
Ø Item specific informaAon Ø Document research data Ø NLP data Ø Catalog informaAon

Research quesAons Ø Query mechanisms support innovaAve reasoning on
archaeological datasets
Ø Query power lies in relaAng and combining
Ø data from different providers, preserving the original meaning and their perspecAve
Ø data from grey literature reports Ø item level with catalog info on archaeological datasets
Research quesAons
Ø Find all bronze coins (item level info, retrieves datasets from mulAple providers)
Ø Find the publishers of all collecAons that contain coins (catalog info)
Ø Find all datasets and grey literature reports that contain bronze antonianus (item level, NLP data and catalog info)
