Project VBI ERAT LVPAThe Internet Tracks of the Roman She-Wolf

  • Traditional corpora:

  • very high quality, difficult to maintain, difficult to search, uncorrelated to complementary resources

  • New Database Projects:

  • varying quality, overlapping contents, continuously updated, easy to search, uncorrelated between each other.

  • Altogether:

  • A conglomerate of highly interrelated archaeological sources

  • of overwhelming detail and volume

  • Ubi-erat-lupa: A European “Culture 2000” Project

  • An aggregation of complementary scientific databases and corpora describing finds with inscriptions and iconography of the Roman era

  • to create a body of unique archaeological knowledge in digital form.


Vbi erat lvpa objective

VBI ERAT LVPA Objective

  • creation of a global index about a set of semi-autonomous sources for global access to the unified knowledge

  • integration of complementary information under a common ontology/schema and identification of common elements in different sources

  • development of an integration algorithm that converges to the best state of knowledge und continuous update

  • creation of a research tool for formulating queries of archaeological content to detect contextual relationships that cannot be derived from interpreting the sources in isolation


Approach

Approach

  • Develop a semantic network based on the CIDOC CRM model to integrate the complementary archaeological sources

  • Data, relevant to global querying over all contents, are extracted, transformed and stored in an RDF repository, that is incrementally updated over time.

  • Integration in two phases:

  • source schema is intellectually interpreted in terms of the CIDOC model

    • “non canonical” data reported to respective source

    • mistakes in sources removed, quality of source improved

  • actual data automatically transformed and stored into an RDF repository

    • an a posteriori data cleaning process removes as many duplicates as can be (semi-) automatically detected

Integration of complementary archaeological sources

Identity Problem

Two approaches:

a) avoid taking two different items for the same => use local id, where uniqueness is guaranteed

b) try to find global names with a high chance to match.

  • Lupa solution is a):

    • We give a serial number to any new object we insert

    • We use the serial number of the source database.

      • Example: P.O: arachne.45305

      • or : P.O: lupa.4501

  • We maintain local id in the global index as valid names and remove detected duplicates continuously.

  • Cost-benefit optimization of over- and under-identification!

    Integration of complementary archaeological sources

    VBI ERAT LVPA Results

    • A method and architecture for integration of diverse archaeological copora on the Roman stone monuments under the CIDOC CRM model.

    • We developed an efficient way for place name recognition

    • We are developing a research tool suitable for formulating queries and drawing conclusions on archaeological data

      • detection of contextual relationships that cannot be derived from interpreting the sources in isolation

      • a method of identifying epigraphic references and finds

    • test bed for the CIDOC CRM model - proved its adequacy

    • First large scale integration project of multiple complementary resources as a global index to the original sources


    Integration of complementary archaeological sources

    Future work

    • integrate more data sources

    • support a mechanism to visualize a source

    • support an automatic mapping process so that archaeologists will be able to maintain the system b themselves.
