• Atomic components

    Reeves, Steve; Streader, David (University of Waikato, Department of Computer Science, 2004-02)
    There has been much interest in components that combine the best of state-based and event-based approaches. The interface of a component can be thought of as its specification and substituting components with the same ...
  • Unifying state and process determinism

    Reeves, Steve; Streader, David (University of Waikato, Department of Computer Science, 2004-02)
    If a coin is given to a deterministic robot that interacts with a deterministic vending machine then is the drink that the robot is delivered determined? Using process definitions of determinism from CSP, CCS or ACP the ...
  • The syntax and semantics of μ-Charts

    Reeve, Greg; Reeves, Steve (University of Waikato, Department of Computer Science, 2004-02)
    μ-Charts is a language for specifying the behaviour of reactive systems. The language is a simplified variant of the well-known language Statecharts that was introduced by Harel. Development of the μ-Charts language is ...
  • DeepDocument: use of a multi-layered display to provide context awareness in text editing

    Masoodian, Masood; McKoy, Sam; Rogers, Bill; Ware, David (University of Waikato, Department of Computer Science, 2004-02)
    The most commonly used view in word processing software shows only the paragraphs of text immediately adjacent to the cursor position. Generally this is appropriate, for example when composing a single paragraph. However, ...
  • Ensembles of nested dichotomies for multi-class problems

    Frank, Eibe; Kramer, Stefan (University of Waikato, Department of Computer Science, 2004-02)
    Nested dichotomies are a standard statistical technique for tackling certain polytomous classification problems with logistic regression. They can be represented as binary trees that recursively split a multi-class ...
  • "Please turn ON your mobile phone" - first impressions of text-messaging in lectures

    Jones, Matt; Marsden, Gary (University of Waikato, Department of Computer Science, 2004-05)
    Previous work by Draper and Brown investigated the use of specialized handsets in increate interactivity in lecture settings. Inspired by their encouraging findings we have been exploring the use of conventional mobile ...
  • Analyzing library collections with starfield visualizations

    Sánchez, J. Alfredo; Twidale, Michael B.; Nichols, David M.; Silva, Nabani N. (Department of Computer Science, 2004-01-01)
    This paper presents a qualitative and formative study of the uses of a starfield-based visualization interface for analysis of library collections. The evaluation process has produced feedback that suggests ways to ...
  • Design and analysis of an efficient distributed event notification service

    Bittner, Sven; Hinze, Annika (Department of Computer Science, University of Waikato, 2004-01-01)
    Event Notification Services (ENS) use the publish/subscribe paradigm to continuously inform subscribers about events they are interested in. Subscribers define their interest in so-called profiles. The event information ...
  • Bayesian network classifiers in Weka

    Bouckaert, Remco R. (Department of Computer Science, 2004-09-01)
    Various Bayesian network classifier learning algorithms are implemented in Weka [10].This note provides some user documentation and implementation details. Summary of main capabilities: _Structure learning of Bayesian ...
  • Language switching in a digital library; does it make a difference if the default language is set to Maori?

    Keegan, Te Taka Adrian Gregory; Cunningham, Sally Jo; Don, Katherine J. (2004-01-01)
    In this paper we investigate the effect of default interface language on usage patterns of the Niupepa digital library (a collection of historic Māori language newspapers), by switching the default interface language between ...
  • Open issues in semantic query optimization in relational DBMS

    Genet, Bryan Howard; Hinze, Annika (Department of Computer Science, University of Waikato, 2004-01-01)
    After two decades of research into Semantic Query Optimization (SQO) there is clear agreement as to the efficacy of SQO. However, although there are some experimental implementations there are still no commercial ...
  • Usability discussions in open source development

    Nichols, David M.; Twidale, Michael B. (Department of Computer Science, 2004-01-01)
    The public nature of discussion in open source projects provides a valuable resource for understanding the mechanisms of open source software development. In this paper we explore how open source projects address issues ...
  • Event notification services: analysis and transformation of profile definition languages

    Jung, Doris; Hinze, Annika (Department of Computer Science, University of Waikato, 2004-01-01)
    The integration of event information from diverse event notification sources is, as with meta-searching over heterogeneous search engines, a challenging task. Due to the complexity of profile definition languages, known ...
  • Mining data streams using option trees (revised edition, 2004)

    Holmes, Geoffrey; Kirkby, Richard Brendon; Pfahringer, Bernhard (Department of Computer Science, The University of Waikato, 2004-01-01)
    The data stream model for data mining places harsh restrictions on a learning algorithm. A model must be induced following the briefest interrogation of the data, must use only available memory and must update itself over ...
