RV4JaCa -- Runtime Verification for Multi-Agent Systems

TL;DR

This paper introduces RV4JaCa, a runtime verification approach for multi-agent systems using JaCaMo, enhancing security by controlling events during execution without altering agent behavior, demonstrated in a hospital bed allocation scenario.

Contribution

It presents a novel runtime verification method for MAS in JaCaMo, enabling event control without modifying agent code, especially for natural language communication in hybrid intelligence contexts.

Findings

Successfully implemented a dialogue flow monitor in a hospital bed allocation MAS.

Demonstrated the approach's effectiveness in controlling natural language interactions.

Enhanced security and reasoning stability in MAS through runtime event control.

Abstract

This paper presents a Runtime Verification (RV) approach for Multi-Agent Systems (MAS) using the JaCaMo framework. Our objective is to bring a layer of security to the MAS. This layer is capable of controlling events during the execution of the system without needing a specific implementation in the behaviour of each agent to recognise the events. MAS have been used in the context of hybrid intelligence. This use requires communication between software agents and human beings. In some cases, communication takes place via natural language dialogues. However, this kind of communication brings us to a concern related to controlling the flow of dialogue so that agents can prevent any change in the topic of discussion that could impair their reasoning. We demonstrate the implementation of a monitor that aims to control this dialogue flow in a MAS that communicates with the user through natural language to aid decision-making in hospital bed allocation.
