Overview

Dr. Gianluca Demartini is a Senior Lecturer in Data Science at the University of Queensland, School of Information Technology and Electrical Engineering. His main research interests are Information Retrieval, Semantic Web, and Human Computation. His research has been supported by the UK Engineering and Physical Sciences Research Council (EPSRC) and by the EU H2020 framework program. He received Best Paper Awards at the AAAI Conference on Human Computation and Crowdsourcing (HCOMP) in 2018 and at the European Conference on Information Retrieval (ECIR) in 2016 and the Best Demo Award at the International Semantic Web Conference (ISWC) in 2011. He has published more than 80 peer-reviewed scientific publications (10 of which in venues with acceptance rate of 20% or lower) including papers at major venues such as WWW, ACM SIGIR, VLDBJ, ISWC, and ACM CHI. He serves as area editor for the Journal of Web Semantics, editorial board member for the Information Retrieval journal, as Crowdsourcing and Human Computation Track co-Chair at WWW 2018.

He has been Senior Program Committee member for HCOMP, the International Conference on Web Engineering (ICWE), and the ACM International Conference on Information and Knowledge Management (CIKM). He is Program Committee member for several conferences including WWW, SIGIR, KDD, IJCAI, ISWC, and ICWSM. He co-organized the Entity Ranking Track at the Initiative for the Evaluation of XML Retrieval in 2008 and 2009.

Before joining the University of Queensland, he was Lecturer at the University of Sheffield in UK, post-doctoral researcher at the eXascale Infolab at the University of Fribourg in Switzerland, visiting researcher at UC Berkeley, junior researcher at the L3S Research Center in Germany, and intern at Yahoo! Research in Spain. In 2011, he obtained a Ph.D. in Computer Science at the Leibniz University of Hanover focusing on Semantic Search.

Research Interests

  • Big Data Analytics
    Designing algorithms and systems that can scale-out to large amounts of data.
  • Crowdsourcing and Human Computation
    Improving the efficiency and effectiveness of human-in-the-loop systems.
  • Knowledge Graphs
    Leveraging structured information in combination with unstructured text to improve the Web user experience.

Research Impacts

My research is focussing on improving the efficiency and effectiveness of human-in-the-loop Web-based information systems. The application domains of my research include text analytics and the intersection between structured (e.g., knowledge graphs) and unstructured (e.g., text) digital content. During my research career I have collaborated with colleagues from several industry and governmental organizations like for example, Google, Microsoft, Yahoo!, IBM, SAP, and The National Archives in UK.
