  • A graphical user interface for Boolean query specification

    Jones, Steve; McInnes, Shona (Computer Science, University of Waikato, 1997-12)
    On-line information repositories commonly provide keyword search facilities via textual query languages based on Boolean logic. However, there is evidence to suggest that the syntactical demands of such languages can lead ...

  • Adaptive models of English text

    Teahan, W.J.; Cleary, John G. (Department of Computer Science, The University of Waikato, 1997-11)
    High quality models of English text with performance approaching that of humans is important for many applications including spelling correction, speech recognition, OCR, and encryption. A number of different statistical ...

  • OZCHI‘96 Industry Session: Sixth Australian Conference on Human-Computer Interaction

    Phillips, Chris; McKauge, Janis (Computer Science, University of Waikato, 1997-11)
    The idea for a specific industry session at OZCHI was first mooted at the 1995 conference in Wollongong, during questions following a session of short papers which happened (serendipitously) to be presented by people from ...

  • Effects of re-ordered memory operations on parallelism

    Littin, Richard H.; Cleary, John G. (Computer Science, University of Waikato, 1997-11)
    The performance effect of permitting different memory operations to be re-ordered is examined. The available parallelism is computed using a machine code simulator. A range of possible restrictions on the re-ordering of ...

  • Constraints on parallelism beyond 10 instructions per cycle

    Cleary, John G.; Littin, Richard H.; McWha, David J.A.; Pearson, Murray W. (Computer Science, University of Waikato, 1997-11)
    The problem of extracting Instruction Level Parallelism at levels of 10 instructions per clock and higher is considered. Two different architectures which use speculation on memory accesses to achieve this level of performance ...

  • Correcting English text using PPM models

    Teahan, W.J.; Inglis, Stuart J.; Cleary, John G.; Holmes, Geoffrey (Computer Science, University of Waikato, 1997-11)
    An essential component of many applications in natural language processing is a language modeler able to correct errors in the text being processed. For optical character recognition (OCR), poor scanning quality or extraneous ...

  • Musical image compression

    Bainbridge, David; Inglis, Stuart J. (Computer Science, University of Waikato, 1997-11)
    Optical music recognition aims to convert the vast repositories of sheet music in the world into an on-line digital format [Bai97]. In the near future it will be possible to assimilate music into digital libraries and users ...

  • Tag based models of English text

    Teahan, W.J.; Cleary, John G. (1997-11)
    The problem of compressing English text is important both because of the ubiquity of English as a target for compression and because of the light that compression can shed on the structure of English. English text is ...

  • Fast convergence with a greedy tag-phrase dictionary

    Peeters, Ross; Smith, Tony C. (1997-11)
    The best general-purpose compression schemes make their gains by estimating a probability distribution over all possible next symbols given the context established by some number of previous symbols. Such context models ...

  • Inducing cost-sensitive trees via instance-weighting

    Ting, Kai Ming (Computer Science, University of Waikato, 1997-09)
    We introduce an instance-weighting method to induce cost-sensitive trees in this paper. It is a generalization of the standard tree induction process where only the initial instance weights determine the type of tree (i.e., ...

  • Usability testing: a Malaysian study

    Yeo, Alvin; Barbour, Robert H.; Apperley, Mark (Computer Science, University of Waikato, 1997-07)
    An exploratory study of software assessment techniques is conducted in Malaysia. Subjects in the study comprised staff members of a Malaysian university with a high Information Technology (IT) presence. The subjects assessed ...

  • Language use in software

    Yeo, Alvin; Barbour, Robert H. (1997-07)
    Many of the popular software we use today are in English. Very few software applications are available in minority languages. Besides economic goals, we justify why software should be made available to smaller cultures. ...

  • Strategies of internationalisation and localisation: a postmodernist’s perspective

    Barbour, Robert H.; Yeo, Alvin (Department of Computer Science, University of Waik, 1997-07)
    Many software companies today are developing software not only for local consumption but for the rest of the world. We introduce the concepts of internationalisation and localisation and discuss some techniques using these ...

  • Localising a spreadsheet: an Iban example

    Yeo, Alvin; Barbour, Robert H. (1997-07)
    Presently, there is little localisation of software to smaller cultures if it is not economically viable. We believe software should also be localised to the languages of small cultures in order to sustain and preserve ...

  • Internationalising a spreadsheet for Pacific Basin languages

    Barbour, Robert H.; Yeo, Alvin (Department of Computer Science, University of Waik, 1997-07)
    As people trade and engage in commerce, an economically dominant culture tends to migrate language into other recently contacted cultures. Information technology (IT) can accelerate enculturation and promote the expansion ...

  • Proceedings of the INTERACT97 Combined Workshop on CSCW in HCI-Worldwide

    Rauterberg, Matthias; Oestreicher, Lars; Grundy, John C. (Department of Computer Science, University of Waik, 1997-07)
    This is the proceedings for the INTERACT97 combined workshop on “CSCW in HCI-worldwide”. The position papers in this proceedings are those selected from topics relating to HCI community development worldwide and to CSCW ...

  • Information seeking retrieval, reading and storing behaviour of library users

    Turner, Kristine (Computer Science, University of Waikato, 1997-06)
    In the interest of digital libraries, it is advisable that designers be aware of the potential behaviour of the users of such a system. There are two distinct parts under investigation, the interaction between traditional ...

  • Learning from batched data: model combination vs data combination

    Ting, Kai Ming; Low, Boon Toh; Witten, Ian H. (Department of Computer Science, University of Waik, 1997-05)
    When presented with multiple batches of data, one can either combine them into a single batch before applying a machine learning procedure or learn from each batch independently and combine the resulting models. The former ...

  • Discovering inter-attribute relationships

    Holmes, Geoffrey (1997-04)
    It is important to discover relationships between attributes being used to predict a class attribute in supervised learning situations for two reasons. First, any such relationship will be potentially interesting to the ...
