    • Double chain-star: An RDF indexing scheme for fast processing of SPARQL joins 

      Meimaris M., Papastefanatos G. (2016)
      State of the art RDF stores often rely on exhaustive indexing and sequential (self-)joins for SPARQL query processing. However, query execution is dependent on, and often limited by the underlying storage and indexing ...

    • Effective cache management and performance limits in information-centric networks 

      Sourlas, V.; Tassiulas, L. (2013)
      Proliferation of content distribution traffic in the Internet is changing the requirements on the networking infrastructure to the extent that radical new architectures are envisioned, where information is addressed by ...

    • Efficient computation of containment and complementarity in RDF data cubes 

      Meimaris M., Papastefanatos G., Anagnostopoulos I., Vassiliadis P. (2016)
      Multidimensional data are published in the web of data under common directives, such as the Resource Description Framework (RDF). The increasing volume and diversity of these data pose the challenge of finding relations ...

    • The eLOD ontology: Modeling economic open data 

      Vafopoulos M., Razis G., Anagnostopoulos I., Vafeiadis G., Negkas D., Galanos E., Tzani A., Skaros I., Glykos K. (2016)
      For decades, valuable economic data was out of reach for most of the people. Gradually, public budgets and tenders are becoming openly available and global initiatives promote financial transparency and data innovation. ...

    • The EvoGen benchmark suite for evolving RDF data 

      Meimaris M., Papastefanatos G. (2016)
      Artificial and synthetic data are widely used for benchmarking and evaluating database, storage and query engines. This is usually performed in static contexts with no evolution in the data. In the context of evolution ...

    • Federation of internet of things testbeds for the realization of a semantically-enabled multi-domain data marketplace 

      Sánchez L., Lanza J., Santana J.R., Agarwal R., Raverdy P.G., Elsaleh T., Fathy Y., Jeong S., Dadoukis A., Korakis T., Keranidis S., O’brien P., Horgan J., Sacchetti A., Mastandrea G., Fragkiadakis A., Charalampidis P., Seydoux N., Ecrepont C., Zhao M. (2018)
      The Internet of Things (IoT) concept has attracted a lot of attention from the research and innovation community for a number of years already. One of the key drivers for this hype towards the IoT is its applicability to ...

    • Learning objects and learning services in the semantic web 

      Hartonas, C.; Gana, E. (2008)
      With the development of the web and the intense research for a semantic web, the need arises for standardized and rigorous semantic specification both of Services on the semantic web and of the objects and processes that ...

    • Modeling influence with semantics in social networks: A survey 

      Razis G., Anagnostopoulos I., Zeadally S. (2020)
      The discovery of influential entities in all kinds of networks (e.g., social, digital, or computer) has always been an important field of study. In recent years, Online Social Networks (OSNs) have been established as a ...

    • On-line storage management with distributed decision making for content-centric networks 

      Sourlas, V.; Gkatzikis, L.; Tassiulas, L. (2011)
      Content traffic proliferation in Internet makes more dire than ever the development of radical new network architectures, where information will be addressed by semantic attributes rather than the origin and destination ...
