A highly adaptive recommender system based on fuzzy logic for B2C e-commerce portals
TL;DR: A prototype of e-commerce portal, called e-Zoco, is introduced, of which main features are a catalogue service intended to arrange product categories hierarchically and describe them through sets of attributes, and a rule-based knowledge learning service to provide the users with knowledge about the existing relationships among the attributes that describe a given product category.
Journal ArticleDOI
A cognitive surveillance system for detecting incorrect traffic behaviors
TL;DR: The multi-agent system paradigm embodies this approach, together with the use of FIPA standards, and a traffic ontology formalizes the domain knowledge, obtaining a high-scalable and flexible system which can be adapted to other domains.
Journal ArticleDOI
Multi-agent architecture for information retrieval and intelligent monitoring by UAVs in known environments affected by catastrophes
TL;DR: The design of a multi-agent architecture which enables the deployment of systems made up of intelligent agents that can monitor environments affected by a catastrophe and provide support to human staff in the decision-making process is proposed.
Journal ArticleDOI
A multi-agent architecture for supporting distributed normality-based intelligent surveillance
TL;DR: This paper discusses the architecture devised by means of a set of autonomous agents that are responsible for the management of different surveillance tasks and for cooperating to monitor complex environments and uses the architecture to deploy a surveillance system to monitor an urban traffic scenario.
