Jesús Camacho-Rodríguez: PAXQuery : Efficient Parallel Processing of Complex XQuery
10.00, room 455, PCRI Abstract Increasing volumes of data are being produced and exchanged over the Web, in particular in tree-structured formats such as XML or JSON. This leads to a need of highly scalable algorithms and tools for processing such data, capable to take advantage of massively parallel processing frameworks. This work considers the …

Dario Colazzo: Processing XML Queries and Updates on Map/Reduce Clusters
14.30, room 435, PCRI Abstract Very large XML documents are generated and processed in several contexts, in particular in those involving scientific data and logs. In order to process such large documents we have designed and implemented techniques based on data partitioning for the evaluation of XQuery queries and updates on Map/Reduce clusters. The proposed …

Melanie Herschel: The Nautilus Analyzer – Understanding and Debugging Data Transformations
14.00, room 445, PCRI Abstract When developing data transformations – a task omnipresent in applications like data integration, data migration, data cleaning, or scientific data processing – developers quickly face the need to verify the semantic correctness of the transformation. Declarative specifications of data transformations, e.g., SQL or ETL~tools, increase developer productivity but usually provide …

Katerina Tzompanaki: Design and Implementation of a tool for formulating recall-oriented structured queries on semantic networks
14.00, room 455, PCRI Abstract In the recent years there is a trend towards the creation of massive metadata repositories, usually based on the RDF/S technology, as in the domain of cultural heritage. ISO21127 (CIDOC Conceptual Reference Model) is a rich conceptual model (or ontology) capable of describing the world stored in such repositories. Simpler …
