PUMA PROGRAMMABLE USER MODELLING APPLICATIONS A basis for modelling knowledge

PUMA PROGRAMMABLE USER MODELLING APPLICATIONS Programmable user models: The story so far

This papers looks in detail at the Programmable User Modelling (PUM) approach to interactive system design. The theoretical background of PUM is discussed and a history of PUM work is outlined. Other related issues such as formal notations, other user modelling techniques used in HCI, and integration are also discussed. An agenda for further work is then proposed.

PUMA PRACTICAL USER MODELLING APPLICATIONS A basis for modelling knowledge

An agenda for modelling knowledge is set down. We argue that for PUM a model that allows for less than perfect behaviour is required. Gärdenfors’ [3] approach is looked at and we explain why we consider that the notion of rationality that underlies Gärdenfors’ approach is too strict for our purposes. It is suggested how we can import epistemic logics based on local reasoning and explicit and im...

Users as rational interacting agents: formalising assumptions about cognition and interaction

One way of assessing the usability of a computer system is to make reasonable assumptions about users' cognition and to analyse how they can be expected to work with the system, using their knowledge and information from the display to achieve their goals. This is the approach taken in Programmable User Modelling Analysis, a technique for predictive usability evaluation of interactive systems. ...

PUMA PRACTICAL USER MODELLING APPLICATIONS The question of abstraction and complexity in user modelling

PUMA PROGRAMMABLE USER MODELLING APPLICATIONS Two prototype architectures for rational interacting agents

Two of the central features that determine how an agent reasons and acts in the world are its attitudes (knowledge, beliefs, goals, values, etc.) and its architecture. In this paper, we present and discuss two alternative agent architectures than have been implemented for different purposes — one as a tool to help designers to think about systems from a user's perspective, and the other as an a...
