Abstract

In this paper we introduce one application layer for information processing in the DIET platform, a MAS development platform. This application layer is basically formed of three types of agents, here called "infocytes", designed to cater for the information needs of information providers, requesters and brokers. We have also defined and implemented under I-Gaia two separate tasks using the well-known Reuters text-classification corpus: an information-pull and an information-push task, mainly to validate the ability of such layer to effectively retrieve information on demand or spontaneously route it to users. We have also analysed the performance achieved using measurements based on precision/recall. The results show that the I-Gaia environment is completely operative and that can achieve this type of tasks without loosing performance with respect to other centralised, non-agent-based technologies with full information about the task.
