The Cognitive Dimensions of an Artifact vis-a-vis Individual Human Users : Studies with Notations for the Temporal
(2001)
Cognitive Technology explores ways in which the cognitive fit between people and technology may be optimized. If this goal is to be achieved we will require methods of assessing tools and information arftifacts in order ...
Fact and Artifact : Reification and Drift in the History and Growth of Interactive Software Systems
(2001)
We discuss the processes and forces informing artifact design and the subsequent drift in requirements and interests in the long-term growth of reified systems. We describe, following Latour, the strategies of technoscience ...
Specifying Multiple Time Granularities in Interactive Systems
(2001)
Time plays an important role in interactive systems, but can be difficult to specify, particularly where temporal properties exist at several different time granularities. The relationship between different time granularities ...
Cognitive Dimensions of Notations: Design Tools for Cognitive Technology
(2001)
The Cognitive Dimensions of Notations framework has been created to assist the designers of notational systems and information artifacts to evaluate their designs with respect to the impact that they will have on the users ...
The evolution and understanding of hierarchical complexity in biology from an algebraic perspective
(2000)
We develop the rigorous notion of a model for understanding state transition systems by hierarchical coordinate systems. Using this we motivate an algebraic definition of the complexity of biological systems, comparing it ...
The making of meaning in societies: semiotic and information-theoretic background to the evolution of communication
(The Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB), 2000)
Learning how to do things with imitation
(AAAI, 2000)
In this paper we discuss how agents can learn to do things by imitating other agents. Especially we look at how the use of different metrics and sub-goal granularity can affect the imitation results. We use a computer model ...
Meaning for observers and agents
(1999)
Claude Shannon formalized the notion of information transmission rate and capacity for pre-existing channels. Wittgenstein in his later work insisted that linguistic meaning be defined in terms of use in language games. ...
