Andronikos
Andronikos is a web-portal closely associated with the STAR project that makes available the semantic indices of the OASIS corpus that have been provided by the Archaeology Data Service. These semantic indices have been produced by the STAR NLP Information Extraction phase using the GATE tool and driven by the English Heritage glossaries, thesauri and archaeological extension of the CIDOC CRM core ontology (the CRM-EH).
The Information Extraction phase produces annotations in two formats: as XML files coupled with content and as RDF triples decoupled from content, both based on CRM-EH based RDF representation of some key grey literature concepts.
The representation as RDF triples enables cross search of both datasets and OASIS reports in the STAR Demonstrator. The XML files show the annotations in context of the original grey literature documents and provides a fuller set of associated information.
The main objective of the web-portal development is to make available the semantic indices and to utilise the resulting semantic annotation files in the form of HTML hypertext documents and associated overview statistics of the annotations abstracted from the XML documents. The portal also makes available a set of Thesauri overlapping tools and evaluation results which, are not given public access but access may be given upon request to avlachid (at) glam.ac.uk.
The portal makes available HTML pages that demonstrate the abstractions that have been produced during the 3 main stages of the Information Extraction Process
- OASIS Metadata: Author submitted metadata
- Preprocess: Summary section, Table of Content, and Heading sections
- CRM (Named Entity Recognition): CIDOC CRM oriented entity metadata. E19_Physical Object, E49_Time Appellation, E53_Place and E57_Material
- CRM-EH (Events Recognition): CRM-EH oriented event metadata. EHE0007_Context, EHE0009_Context Find, EHE0030_Material, EHE1001_ContextEvent, EHE1002_ContextFindProductionEvent and EHE1004_ContextFindDepositionEvent
Andreas Vlachidis
Andreas Vlachidis is a Research Assistant in the Hypermedia Research unit at the University of Glamorgan and is currently writing up his PhD in the area of natural language processing, producing semantic annotations conforming to the CIDOC CRM ontology. He has presented his research on information extraction at various international conferences and workshops, including the 1st ISKO-UK Conference at UCL, the MTSR'11 at Yasar University (Izmir)and the CLA'11 and has published in the ASLIB Proceedings journal. He was awarded the prize for Best Overall Presentation at the 4th Research Students Workshop of the Faculty of Advanced Technology at Glamorgan University and the prize for Best Paper on the Semantics Track of the CLA'11 conference. He has previously worked as Division Leader for Computing Courses at North College in Thessaloniki and as ICT Developments Manager in the eCommerce domain.
