Abstract:
A method and apparatus are provided to infer, from monitored user activity, appropriate updates to a respective user profile. The method and apparatus are suitable for use with applications programs that customise services based upon data and attributes stored in a user profile. The apparatus is arranged to personalise various aspects of a preferred profile updating process on the basis of stored user preferences, applying meta-rules to apply those user preferences to the definition of a set of personalised rule weights to be applied in a fuzzy inference process that infers profile updates by applying fuzzy rules and fuzzy sets to the analysis of event statistics derived from the results of user monitoring. The personalised rule weights are applied to selectively adjust the effect of particular fuzzy rules. In addition, mapping of event statistics to fuzzy rule premises in the fuzzy inference process may be personalised through the use of user-defined fuzzy sets.
