    Music is traditionally retrieved by title, composer or subject classification. It is possible, with current technology, to retrieve music from a database on the basis of a few notes sung or hummed into a microphone. This ...
  • Teaching novice conceptual data modellers to become experts

    Venable, John R. (University of Waikato, Department of Computer Science, 1995-09)
    This paper describes teaching practices designed to help novice data modellers become expert data modellers. We base these practices on extant empirical research which highlights the strengths of expert data modellers and ...
  • A logic for specifying and reasoning about cooperative environments

    Reeves, Steve (University of Waikato, Department of Computer Science, 1995-08)
    In this paper we describe the current progress of an attempt to develop a logic which will allow us to specify required properties of systems which typically consist of a single interactive program being used, probably ...
  • Towards an integrated refinement environment for formal program development

    Reeves, Steve; Grundy, John C. (University of Waikato, Department of Computer Science, 1995-08)
    One of the main hurdles to the general adoption of formal program development techniques is a lack of tools to support their use in combination with more traditional development techniques. This paper describes an integrated ...
  • Writing anxiety in computer science students

    Cunningham, Sally Jo; Holmes, Geoffrey (University of Waikato, Department of Computer Science, 1995-08)
    Effective written communication skills are recognized as essential for computing professions, but are notoriously difficult to impart to our students. One problem in teaching computing students to write may be their attitudes ...
  • Building a public digital library based on full-text retrieval

    Witten, Ian H.; Nevill-Manning, Craig G.; Cunningham, Sally Jo (University of Waikato, Department of Computer Science, 1995-08)
    Digital libraries are expensive to create and maintain, and generally restricted to a particular corporation or group of paying subscribers. While many indexes to the World Wide Web are freely available, the quality of ...
  • An investigation into the use of machine learning for determining oestrus in cows

    Mitchell, R. Scott; Sherlock, Robert A.; Smith, Lloyd A. (University of Waikato, Department of Computer Science, 1995-08)
    A preliminary investigation of the application of two well-known machine learning schemes—C4.5 and FOIL—to detection of oestrus in dairy cows has been made. This is a problem of practical economic significance as each ...
  • Signal processing for melody transcription

    McNab, Rodger J.; Smith, Lloyd A.; Witten, Ian H. (University of Waikato, Department of Computer Science, 1995-08)
    MT is a melody transcription system that accepts acoustic input, typically sung by the user, and displays it in standard music notation. It tracks the pitch of the input and segments the pitch stream into musical notes, ...
  • A teaching and support tool for building formal models of graphical user-interfaces

    Reeves, Steve (University of Waikato, Department of Computer Science, 1995-08)
    In this paper we propose the design of a tool that will allow the construction of a formal, textual description of a software system even if it has a graphical user-interface as a component. An important aspect of this ...
  • Applying machine learning to subject classification and subject description for information retrieval

    Cunningham, Sally Jo; Summers, Brent (University of Waikato, Department of Computer Science, 1995-06)
    This paper describes an experiment in applying standard supervised machine learning algorithms (C4.5 and Induct) to the problem of developing subject classification rules for documents. These algorithms are found to produce ...
  • The development of Holte's 1R Classifier

    Nevill-Manning, Craig G.; Holmes, Geoffrey; Witten, Ian H. (University of Waikato, Department of Computer Science, 1995-06)
    The 1R procedure for machine learning is a very simple one that proves surprisingly effective on the standard datasets commonly used for evaluation. This paper describes the method and discusses two areas that can be ...
  • Instance-based learning: nearest neighbour with generalisation

    Martin, Brent (University of Waikato, Department of Computer Science, 1995-05)
    Instance-based learning is a machine learning method that classifies new examples by comparing them to those already seen and in memory. There are two types of instance-based learning; nearest neighbour and case-based ...
  • Applications for bibliometric research in the emerging digital library

    Cunningham, Sally Jo; Vallabh, Mahendra (University of Waikato, Department of Computer Science, 1995-05)
    A large amount of research literature has recently become available on the Internet through "digital libraries". This migration of information from paper to electronic media promises to have a huge impact on the way that ...
