A geo-temporal information extraction service for processing descriptive metadata in digital libraries

In the context of digital map libraries, resources are usually described according to metadata records that define the relevant subject, location, time-span, format and keywords. On what concerns locations and time-spans, metadata records are often incomplete or they provide information in a way that is not machine-understandable (e.g. textual descriptions). This paper presents techniques for extracting geotemporal information from text, using relatively simple text mining methods that leverage on a Web gazetteer service. The idea is to go from human-made geotemporal referencing (i.e. using place and period names in textual expressions) into geo-spatial coordinates and time-spans. A prototype system, implementing the proposed methods, is described in detail. Experimental results demonstrate the efficiency and accuracy of the proposed approaches

Enabling European archaeological research: The ARIADNE E-infrastructure

Research e-infrastructures, digital archives and data services have become important pillars of scientific enterprise that in recent decades has become ever more collaborative, distributed and data-intensive. The archaeological research community has been an early adopter of digital tools for data acquisition, organisation, analysis and presentation of research results of individual projects. However, the provision of einfrastructure and services for data sharing, discovery, access and re-use has lagged behind. This situation is being addressed by ARIADNE: the Advanced Research Infrastructure for Archaeological Dataset Networking in Europe. This EUfunded network has developed an einfrastructure that enables data providers to register and provide access to their resources (datasets, collections) through the ARIADNE data portal, facilitating discovery, access and other services across the integrated resources. This article describes the current landscape of data repositories and services for archaeologists in Europe, and the issues that make interoperability between them difficult to realise. The results of the ARIADNE surveys on users' expectations and requirements are also presented. The main section of the article describes the architecture of the einfrastructure, core services (data registration, discovery and access) and various other extant or experimental services. The ongoing evaluation of the data integration and services is also discussed. Finally, the article summarises lessons learned, and outlines the prospects for the wider engagement of the archaeological research community in sharing data through ARIADNE

Trends in Digital Cultural Heritage Management and Applications

We present some recent trends in the field of digital cultural heritage management and applications including digital cultural data curation, interoperability, open linked data publishing, crowd sourcing, visualization, platforms for digital cultural heritage, and applications. We present some examples from research and development projects of MUSIC/TUC in those areas.The Fourth International Conference on Digital Presentation and Preservation of Cultural and Scientific Heritage—DiPP2014 is supported by the Ministry of Education and Science and is under the patronage of UNESCO

Thesauri Design to improve access to Cartographic Heritage in the context of the Spatial Data Infrastructures

Tecnologías de la Información Geográfica, ontologías, Información Geográfica, interoperabilidad. The access of historians and document management specialists to documentary funds and old cartography is at times arduous due to the scattering of maps throughout different map libraries. Thus, it would be of interest to be able to access all available information remotely, following the Spatial Data Infrastructures (SDI) guidelines. DIGMAP is a cooperative project between six European countries that proposes to develop a solution for indexing, searching and browsing, through a thesaurus, in the European collections of digitized historical maps. It will be possible to match them with the geographic areas covered by each map in the collection and to find it on them, based on standard and open data models. These results will be useful for local digital map libraries, especially if it is of historical – cultural importance, or as interoperable components for wider and distributed systems. This project takes advantage of thesauri technologies to develop three major subsystems: On one hand, the gazetteer for managing and providing access to multilingual information relating to geographic features like geographic coordinates, names of places or areas and historical events related with the geographic points, places or areas (with dates or time intervals); The authority file to maintain and provide easy access to the author’s information and identification and disambiguating from similar and duplicate authors; and on the other hand, the map services for providing access to map information in raster and vector formats. The paper presents an early overview on the DIGMAP project, particularly focusing on the multilingual Thesauri aspects with the aim of providing solutions for the cartographic heritage framework, applying the main Spatial Data Infrastructures guidelines. ISO 19112 (Spatial Reference by Geographic Identifiers) will also be considered and its geographic identifiers issues

The European Landscape of Qualitative Social Research Archives: Methodological and Practical Issues

In this article I set about describing current practices in archiving and reusing qualitative data. I discuss where can you find archived sources of qualitative data, and discuss some of the debates surrounding methodological, ethical and theoretical considerations relating to re-using data. I then address more pragmatic issues involved acquiring, preserving, providing access to and supporting the use of the data. Where best do qualitative data collections sit?in traditional libraries or archives alongside historical documents or as part of more holistic digital collections of contemporary social science research resources? This question relates to accessibility, resource discovery and cataloging methods, data preparation and documentation and promotional and outreach efforts to encourage data use. The ESDS Qualidata unit at the UK Data Archive is used as case study for showcasing archival practices, and is situated within the broader European landscape of social science-oriented data archives. Infrastructure requirements for running an archive are discussed and a look forward future developments
