Overview

Dr. Gianluca Demartini is an Associate Professor 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 Australian Research Council (ARC), 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 100 peer-reviewed scientific publications including papers at major venues such as WWW, ACM SIGIR, VLDBJ, ISWC, and ACM CHI. He has given several invited talks, tutorials, and keynotes at a number of academic conferences (e.g., ISWC, ICWSM, WebScience, and the RuSSIR Summer School), companies (e.g., Facebook), and Dagstuhl seminars. He is an ACM Distinguished Speaker since 2015 and has been a TEDx speaker in 2019.

He serves as co-editor in chief for the Human Computation journal, area editor for the Journal of Web Semantics, and editorial board member for the Information Retrieval journal. He is General co-Chair for the ACM International Conference on Information and Knowledge Management (CIKM) 2021. He has been Senior Program Committee member for, among others, the ACM Conference on Research and Development in Information Retrieval (SIGIR), the ACM Web Search and Data Mining (WSDM) Conference, the AAAI Conference on Human Computation and Crowdsourcing (HCOMP), and the International Conference on Web Engineering (ICWE). He is Program Committee member for several conferences including WWW, SIGIR, KDD, IJCAI, AAAI, ISWC, and ICWSM. He was Crowdsourcing and Human Computation Track co-Chair at WWW 2018 and co-chair for the Human Computation and Crowdsourcing Track at ESWC 2015. He co-organized several workshops and tutorials at international conferences as well as 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

The research led by A/Prof. Demartini focuses on improving the efficiency and effectiveness of human-in-the-loop artificial intelligence systems. The application domains of his research include text analytics and the intersection between structured (e.g., knowledge graphs) and unstructured (e.g., text) digital content. During his research career he has collaborated with colleagues from several industry and governmental organizations like for example, Facebook,m Google, Microsoft, Yahoo!, IBM, SAP, and The National Archives in the UK.
