Internet Archaeology 30

Experimenting with hyperlinked media, the 'Ye Devill Among Ym' Project explores the potential of interactive media to communicate a data-rich study to a wider audience, still including archaeologists but simultaneously penetrable by scholars from other disciplines and non-academics. Using new research into the material culture of discipline employed by the early post-Reformation Scottish church as a case study, the project strives not only to describe experiences in the past, but also to translate both those experiences and elements of the archaeological interpretative process.

Differing terminology and database structure hinders meaningful cross search of excavation datasets. Matching free text grey literature reports with datasets poses yet more challenges. Conventional search techniques are unable to cross search between archaeological datasets and Web-based grey literature.Results are reported from two AHRC funded research projects that investigated the use of semantic techniques to link digital archive databases, vocabularies and associated grey literature. STAR (Semantic Technologies for Archaeological Resources) was a collaboration between the University of Glamorgan, Hypermedia Research Unit and English Heritage (EH). The main outcome is a research Demonstrator (available online), which cross searches over excavation datasets from different database schemas, including Raunds Roman, Raunds Prehistoric, Museum of London, Silchester Roman and Stanwick sampling. The system additionally cross searches over an extract of excavation reports from the OASIS index of grey literature, operated by the Archaeology Data Service (ADS).A conceptual framework provided by the CIDOC Conceptual Reference Model (CRM) integrates the different database structures and the metadata automatically generated from the OASIS reports by natural language processing techniques. The methods employed for extracting semantic RDF representations from the datasets and the information extraction from grey literature are described. The STELLAR project provides freely available tools to reduce the costs of mapping and extracting data to semantic search systems such as the Demonstrator and to linked data representation generally. Detailed use scenarios (and a screen capture video) provide a basis for a discussion of key issues, including cost-benefits, ontology modelling, mapping, terminology control, semantic implementation and information extraction issues.The scenarios show that semantic interoperability can be achieved by mapping and extracting different datasets and key concepts from OASIS reports to a central RDF based triple store. It is not necessary to expose the full detail of the ontological model; the Demonstrator shows that user interfaces for retrieval (or mapping) systems can be expressed using familiar archaeological concepts. Working with the CRM-EH archaeological extension of the CIDOC CRM ontology allows specific archaeological queries, while permitting interoperability at the more general CRM level, potentially extending to other areas of cultural heritage. The ability to connect published datasets with the hitherto under-utilised grey literature holds potential for meta studies, where aggregate patterns can be compared and hypotheses for future detailed investigation uncovered. Connecting the interpretation with the underlying context data via the semantic model facilitates the revisiting of previous interpretations by third parties, the possibility of juxtaposing parallel interpretations, or exposing the data to new research questions.

It is often stated that trying to deal with information on the internet is like drinking from a firehose. But trying to put together a book about the current state of digital anything must be rather more like trying to paint a landscape from the window of a moving train. By the time the painting is complete, the scenery has changed dramatically. This puts books on digital approaches to academic disciplines in an interesting position: by the time a volume makes it into the hands of its readers, it is already a historical document as well as a scholarly work. The editors of Digital Research in the Study of Classical Antiquity are very aware of this: as they state, the book seeks "to create a snapshot of the research activities of Digital Classicist members as represented by a selection of the papers given at our Summer seminars and conference panels in one particular year, 2007" (p10). When one considers that the printed volume went to press in 2010, and is being reviewed in 2011, this means that almost four years—a digital eternity—have passed since most of the papers were first composed. I think, therefore, it will be most useful to discuss Digital Research from two perspectives: first, in terms of its scholarly contribution, and second, in terms of what the framing of this work and the identity of its contributors tell us about a particular moment in the history of the field of 'digital humanities
