    • Assessing FAIR data principles against the 5-Star open data principles 

      Hasnain, Ali; Rebholz-Schuhmann, Dietrich (Springer Verlag, 2018-08-02)
      Access to biomedical data is increasingly important to enable data driven science in the research community. The Linked Open Data (LOD) principles (by Tim Berner-Lee) have been suggested to judge the quality of data by its ...

    • Biofed: federated query processing over life sciences linked open data 

      Hasnain, Ali; Mehmood, Qaiser; Sana e Zainab, Syeda; Saleem, Muhammad; Warren, Claude; Zehra, Durre; Decker, Stefan; Rebholz-Schuhmann, Dietrich (Springer Nature, 2017-03-15)
      Background: Biomedical data, e. g. from knowledge bases and ontologies, is increasingly made available following open linked data principles, at best as RDF triple data. This is a necessary step towards unified access to ...

    • Biomedical semantic resources for drug discovery platforms 

      Hasnain, Ali; Rebholz-Schuhmann, Dietrich (Springer Verlag, 2017-11-08)
      The biomedical research community is providing large-scale data sources to enable knowledge discovery from the data alone, or from novel scientific experiments in combination with the existing knowledge. Increasingly ...

    • Cataloguing and Linking Life Sciences LOD 

      Hasnain, Ali; Fox, Ronan; Deus, Helena F.; Decker, Stefan (2012)
      The Life Sciences Linked Open Data (LSLOD) Cloud is currently comprised of multiple datasets that add high value to biomedical research. The ability to navigate through these datasets in order to derive and discover new ...

    • A collaborative methodology for developing a semantic model for interlinking Cancer Chemoprevention linked-data sources 

      Zeginis, Dimitris; Hasnain, Ali; Loutas, Nikolaos; Deus, Helena; Fox, Ronan; Tarabanisa, Konstantinos (IOS press, 2013)
                                 This paper proposes a collaborative methodology for developing semantic data models. The proposed methodology for the semantic model development follows a meet-in-the-middle approach. On the ...

    • An evaluation of SPARQL federation engines over multiple endpoints 

      Saleem, Muhammad; Khan, Yasar; Hasnain, Ali; Ermilov, Ivan; Ngonga Ngomo, Axel-Cyrille (NUI Galway, 2018-04-23)
      Due to decentralized and linked architecture underlying Linking Data, running complex queries often require collecting data from multiple RDF datasets. The optimization of the runtime of such queries, called federated ...

    • Extending largeRDFBench for multi-source data at scale for SPARQL endpoint federation 

      Hasnain, Ali; Saleem, Muhammad; Ngomo, Axel-Cyrille Ngonga; Rebholz-Schuhmann, Dietrich (IOS Press, 2018)
      Querying the Web of Data is highly motivated by the use of federation approaches mainly SPARQL query federation when the data is available through endpoints. Different benchmarks have been proposed to exploit the full ...

    • LargeRDFBench: A billion triples benchmark for SPARQL endpoint federation 

      Saleem, Muhammad; Hasnain, Ali; Ngonga Ngomo, Axel-Cyrille (Elsevier, 2018-01-12)
      Gathering information from the distributed Web of Data is commonly carried out by using SPARQL query federation approaches. However, the fitness of current SPARQL query federation approaches for real applications is difficult ...

    • Linked Biomedical Dataspace: Lessons Learned integrating Data for Drug Discovery 

      Hasnain, Ali; Kamdar, Maulik; Deus, Helena; Mehdi, Muntazir; Decker, Stefan (Springer, 2014)
      The increase in the volume and heterogeneity of biomedical data sources has motivated researchers to embrace Linked Data (LD) technologies to solve the ensuing integration challenges and enhance information discovery. As ...

    • Querying over Federated SPARQL Endpoints - A State of the Art Survey 

      Rakhmawati, Nur; Umbrich, Jürgen; Karnstedt, Marcel; Hasnain, Ali; Hausenblas, Michael (2013)
      The increasing amount of Linked Data and its inherent distributed nature have attracted significant attention throughout the research community and amongst practitioners to search data, in the past years. Inspired by ...

    • ReVeaLD: A user-driven domain-specific interactive search platform for biomedical research 

      Kamdar, Maulik; Hasnain, Ali; Decker, Stefan; Deus, Helena F. (2013)

    • Reveald: a user-driven domain-specific interactive search platform for biomedical research 

      Kamdar, Maulik R.; Zeginis, Dimitris; Hasnain, Ali; Decker, Stefan; Deus, Helena F. (Elsevier BV, 2014-02-01)

    • A Roadmap for navigating the Life Sciences Linked Open Data Cloud 

      Hasnain, Ali; Sana e Zainab, Syeda; Kamdar, Maulik; Mehmood, Qaiser; Deus, Helena; Mehdi, Muntazir; Decker, Stefan (2014)
      Multiple datasets that add high value to biomedical research have been exposed on the web as a part of the Life Sciences Linked Open Data (LSLOD) Cloud. The ability to easily navigate through these datasets is crucial for ...

    • SPORTAL: Profiling the Content of Public SPARQL Endpoints 

      Hasnain, Ali; Mehmood, Qaiser; Sana e Zainab, Syeda; Hogan, Aidan (IGI Global, 2016)
      Access to hundreds of knowledge bases has been made available on the Web through public SPARQL endpoints. Unfortunately, few endpoints publish descriptions of their content (e.g., using VoID). It is thus unclear how agents ...

    • SPORTAL: Searching for Public SPARQL Endpoints 

      Hasnain, Ali; Mehmood, Qaiser; Zainab, Syeda Sana e; Hogan, Aidan (NUI Galway, 2016-10)
      There are hundreds of SPARQL endpoints on the Web, but finding an endpoint relevant to a client s needs is difficult: each endpoint acts like a black box, often without a description of its content. Herein we briefly ...
