    Rogers, Bill; Masoodian, Masood; Apperley, Mark (ACM, 2018)
    Whilst the primary purpose of conferences is work — formal exchange and sharing of information — they almost always also include elements of play: Informal social and entertainment elements, such as receptions, dinners, ...
  • Mining algorithmic complexity in full-text scholarly documents

    Bakar, Abu; Safder, Iqra; Hassan, Saeed-Ul (The University of Waikato, 2018)
    Non-textual document elements (NTDE) like charts, diagrams, algorithms play an important role to present key information in scientific documents [1]. Recent advancements in information retrieval systems tap this information ...
  • Mining scientific trends based on topics in conference call for papers

    Bakar, Abu; Arshad, Noor; Safder, Iqra; Hassan, Saeed-Ul (The University of Waikato, 2018)
    Ever since analyzing scientific topics and evolution of technology have become vital for researchers, academics, funding institutes and research administration departments, there is a crucial need to mine scientific trends ...
  • Exploring research data management from a data user’s perspective

    Wu, Yejun (The University of Waikato, 2018)
    Current research data management practices focus more on data col-lecting, curating and sharing than on supporting data use and reuse. This re-search studies research data management from a data user’s perspective and aims ...
  • Deep feature engineering using full-text publications

    Safder, Iqra; Batool, Hafsa; Hassan, Saeed-Ul (The University of Waikato, 2018)
    We have observed a rapid proliferation in scientific literature and advancements in web technologies has shifted information dissemination to digital libraries [1]. In general, the research conducted by scientific community ...
  • A framework for bibliographic recommendation system based on Heterogeneous Retrieval Model?

    Anthony, Poonam; Bhowmick, Plaban Kumar (The University of Waikato, 2018)
    In this paper, we propose an architectural framework for recommending heterogeneous resources in a digital library.We present an outline of our proposed recommendation framework, and discuss brie its performance over ...
  • Clustering of research papers based on sentence roles

    Fukuda, Satoshi; Tomiura, Yoichi (The University of Waikato, 2018)
    In an academic paper search, particularly a search to confirm the originality of a us-er’s research and to create survey articles, it is important that the search returns com-prehensive results related to the user’s ...
  • Using topic modeling to understand workplace health and safety ownership

    Goh, Dion Hoe-Lian; Lee, Chei Sian; Theng, Yin Leng; Zheng, Han; Aung, Htet Htet; Aroor, Megha Rani; Lee, Edmund Wei Jian; Li, Chen (The University of Waikato, 2018)
