This paper uses CIDOC CRM and CRM-based models (CRMarchaeo, CRMsci) to represent archaeological excavation activities and the observations of archaeologists during their work in the excavation field. These observations are usually recorded in documen

In this paper, we investigate the problem of efficiently evaluating SPARQL queries, over large amount of linked data utilizing distributed NoSQL system. We propose an efficient approach for partitioning large linked data graphs using distributed fram

In this paper, we investigate the problem of efficiently evaluating (Basic Graph Pattern) BGP SPARQL queries over a large amount of RDF data. We propose an effective data model for storing RDF data in a document database using maximum replication fac

In this paper, we investigate the problem of view selection for workloads of conjunctive queries under bag and bag-set semantics. In particular, for both semantics we aim to limit the search space of candidate viewsets. We also start delineating boun

Metadata interoperability requires the development of mappings and crosswalks between different schemas. Crosswalks development is a laborious and complex task especially when metadata of compound objects include hierarchical structures. A typical ca

In this article we analyze the main semantics of archival description, expressed through Encoded Archival Description (EAD). Our main target is to map the semantics of EAD to the CIDOC Conceptual Reference Model (CIDOC CRM) ontology as part of a wide
