Abstract

This paper attempts to construct a flexible and effective organisation involving users and middle agents in distributed information systems. In particular, middle agents are employed to organise users according to users" expressed characteristics (e.g. behaviour). Due to the distributed and dynamically changing properties of users, middle agents are used to search suitable information resources in response to user requests. During search, middle agents also monitor and recognise user behaviour, and group users that have matching behaviour together. So eventually users with similar preferences or interests can be clustered into the same community. Self-organising communities reduce the difficulties of human design work on organisation and user similarity calculation, and avoid the constraints due to the design. The user preferences, at the same time, are reflected accurately. Simulated experiments have shown that self-organising communities can organise users properly, and have continuously improved search speed and search efficiency as the communities are correctly formed. In addition, the formation of communities was scalable as number of users increased.
