An adaptable framework for integrating and querying sensor data
(2011)Sensor data generated by pervasive applications are very diverse and are rarely described in standard or established formats. Consequently, one of the greatest challenges in pervasive systems is to integrate heterogeneous ... -
Aggregating Metadata for Europeana: the Greek paradigm
(2011)Europeana is an evolving service that tries to be a single access point for Europe’s cultural heritage. The metadata aggregation for Europeana is a procedure that needs interoperability and software tools for transforming ... -
Automatic Generation of Crosswalks through CIDOC CRM
(2012)In this paper, we propose an algorithm that automatically generates crosswalks between metadata schemas. The algorithm exploits the mappings between the schemas and the CIDOC Conceptual Reference Model (CRM), defined as ... -
Benchmarking library and application software with Data Envelopment Analysis
(2011)Library software is generally believed to be well-structured and follows certain design guidelines due to the need of continuous evolution and stability of the respective APIs. We perform an empirical study to investigate ... -
Building Digital Collections for Archeological Sites: metadata Requirements and CIDOC CRM Extension
(2011)Cultural heritage information management and provision can be improved by the usage of Internet and related technologies. The research effort presented in this paper focuses on the creation of a digital collec- tion representing ... -
Building Standardized Digital Collections: resCarta Tools, a Demo
(2009)ResCarta Tools are a suite of open source software applications which can assist in the creation of standardized digital objects. ResCarta Tools are open and modular in their design. Modules for creating digital objects ... -
Cataloging for a billion word library of Greek and Latin
(2014)This paper reports work on a catalog that includes not only standard metadata but also a complete reference transcription for each work so that users can explicitly cite not only every version but also every word in every ... -
Comparing metadata quality in the Europeana context
(2012)The quality of the metadata affects the interoperability of the collections and the quality of all search results, and is important to the success of Europeana. It is not obvious how to define quality metrics, on different ... -
Data Brokers: building collections through automated negotiation
(2004)Collecting digital materials is time-consuming and can gain from automation. Since each source - and even each acquisition - may involve a separate negotiation of terms, a collector may prefer to use a broker to represent ... -
A decentralized infrastructure for the efficient management of resources in the web of data
(2012)A key requirement in linking open data refers to the rendering of such data easy to explore and consume. Such a requirement is critical for the overall quality of linked data in terms of consistency and interlinking. ... -
Defining a semantic mapping of VRA Core 4.0 to the CIDOC conceptual reference model
(2012)In the recent decades, we have witnessed a tremendous proliferation of metadata schemas, particularly in the cultural heritage domain. As a consequence, cultural heritage communities face a growing need to integrate these ... -
Describing immovable monuments with metadata standards
(2012)Collections with immovable monuments are less researched than other material of our culture from the aspect of description. This led us to study the metadata elements hosted in various heterogeneous schemas by local ... -
Discovering the structure and impact of the digital library evaluation domain
(2017-06)The multidimensional nature of digital libraries evaluation domain poses several challenges to the research communities that intend to assess criteria, methods, products and tools, and also practice them. The amount of ... -
Discovering the Topical Evolution of the Digital Library Evaluation Community
(2015)The successful management of textual information is a rising challenge for all the researchers’ communities, in order firstly to assess its current and previous statuses and secondly to enrich the level of their metadata ... -

Exploratory Web Searching with Dynamic Taxonomies and Results Clustering
(2009)This paper proposes exploiting both explicit and mined metadata for enriching Web searching with exploration services. On-line results clustering is useful for providing users with overviews of the results and thus allowing ... -
Exploratory Web Searching with Dynamic Taxonomies, Results Clustering and Visualization
(2009)The general objective of this dissertation is to elaborate on methods and techniques for exploring and progressively refining large volumes of heterogeneous information, through the provision of appropriate models of ...
