1 Semantic Technologies for Archaeology Resources: Results from the STAR Project C. Binding, K. May 1, R. Souza, D. Tudhope, A. Vlachidis Hypermedia Research Unit, University of Glamorgan 1 English Heritage

2 STAR Project - Aims Investigate semantic technologies for integrating and cross searching datasets and associated grey literature Current situation is one of fragmented datasets and applications, with different terminology systems Need for integrative metadata framework EH have designed an upper ontology based on CRM standard

3 STAR Project - General Architecture Applications Server Side, Rich Client, Browser Web Services, SQL, SPARQL RDF Based Semantic Layer (CRM / CRMEH / SKOS) Indexing Conversion Data Mapping / Normalisation Grey literature EH thesauri, glossaries STAN RRAD MoLAS LEAP RPRE

4 Grey Literature Information Extraction (Andreas Vlachidis, Renato Souza) Looking to extract CRM-EH period, context, find, sample entities Aim to cross search within data

5 Semantic Annotations to RDF triples Example: layers were found to contain a relatively large amount of broken, unabraded pottery The phrase generates three Semantic Annotation types aligned to CRM-EH ontology: EHE1004.ContextFindDepositionEvent, EHE0005.Group, EHE0009.ContextFind <crmeh:ehe0005.group rdf:about=" <dc:source rdf:resource=" /> <crm:p2f.has_type> <crm:e55.type> <rdf:value>layers</rdf:value> <crmeh:ehp10f.is_represented_by rdf:resource=" </crm:e55.type> </crm:p2f.has_type> <crm:p3f.has_note> <crm:e62.string> <rdf:value>...this deposit. These layers were found to cont...</rdf:value> </crm:e62.string> </crm:p3f.has_note> </crmeh:ehe0005.group>

6 Multiple views possible on underlying model Previous prototype offered point to point browsing of full CRM-EH ontology Current prototype presents a different search/browsing model in user interface based on use scenarios from STAR workshops Retains the benefits of CRM standard for inter-operability,
