4 GIS as a platform for Po-BASyN A broadly interdisciplinary research project: huge amount of heterogeneous data need for high accuracy and completeness Main GIS functionalities [after Raper and Maguire, 1992]: acquisition structuration manipulation query and analysis presentation and navigation Collaboration among researchers becomes fundamental on two levels: data sharing analytical procedures sharing + the Web = WebGIS geodata sharing Towards a collaborative platform based on Web technologies

7 WebGIS navigation: an example Database search Results list Map Site details

8 WebGIS main Functionalities Digital Library helping users to find information about scientific publications e-library Ceramic types Db Collaborative editing platform for Archaeology researcher and students Online database of ceramic type collections Sites Db WebGIS of Bronze Age sites in northern Italy Web GIS Online database of Bronze Age sites in northern Italy

9 e-library In order to effectively describe contents beyond a keyword based approach, and to support effective forms of information retrieval, users must have available a domain ontology whose elements can be selected as indicators of the topics treated in the publications Example Searching for: Sicily, Bronze Age The system will retrieve the article The early bronze age Village of Mursia annotated as Mursia, Early Bronze Age partof Sicily Bronze Age Pantelleri a partof partof Early Bronze Age Mursia period place Publication: The early bronze age Village of Mursia

10 Historical Historical period period Thing Thing e-library Ontology The ontology has to be designed by archaeology professors and researchers with the aid of knowledge engineers. The e-library provides on-line tool to maintain and evolve the ontology.

11 e-library Web Interface The e-library allows content editors to describe semantically all the publications in a collaborative and simple way, by adopting a simple web-based user interface. In particular this description will be performed manually by the students, while archaeology professors and researchers will supervise the work and will progressively refine/maintain the domain ontology.

12 ArcheoServer.it In 2005, the chair of Prehistory and Protohistory - University of Milan, the Department of Informatics, Systems and Communication - University of Milan- Bicocca and the Department of Archaeology - University of Bologna, have started a long-term project for the creation of a set of Web-oriented services aimed at supporting the sharing of knowledge on prehistory and protohistory in Italy. The main objective is the creation of a Web portal which will provide a collaborative platform for the exchange of scientific information among the communities of Italian archaeology researchers.
