User Modelling for Information Retrieval from Multidatabases

By Lachlan Mackinnon Michael and Michael Wilson


The design options in resolving heterogeneous data source access from a single query, and for a supporting user modelling component are discussed. The MIPS system is used as an example to consider the role of user modelling in automatically generating hypermedia presentations of the information retrieved from such distributed data sources whose semantics are unknown to its users. A user modelling component from a previous system was able to be used, showing its portability. The opportunities for the application of user modelling to tailor the retrieval and presentation process are investigated, not only for query construction and information filtering, but throughout the entire process. Keywords user modelling, multidatabase, intelligent interface INTRODUCTION The traditional use for user modelling in information retrieval [1] and filtering [2] tasks had been to establish a description of users' interests to supplement queries. User models are generally acquired actively by asking ..
