HACID is an Innovation Action funded under the Horizon Europe Programme (Grant Agreement ID: 101070588). It develops a novel hybrid collective intelligence for decision support to professionals facing complex open-ended problems, promoting engagement, fairness and trust.

A decision support system is proposed that is based on structured domain knowledge, semi-automatically assembled in a domain knowledge graph from available data sources, such as scientific and gray literature.

Given a specific case within the addressed domain, a pool of experts is consulted to (i) extract supporting evidence and enrich it, generating a case knowledge graph (CKG) as a subset of the DKG, and (ii) provide one or more solutions to the problem. Exploiting the CKG, the HACID-DSS gathers the expert advice in a collective solution that aggregates the individual opinions and expands them with machine-generated suggestions. In this way, HACID harnesses the wisdom of the crowd in open-ended problems, relying on a traceable process based on supporting evidence for better explainability.

A set of evaluation methods is proposed to deal with domains where ground truth is not available, demonstrating the suitability of the proposed approach in a wide range of application domains. Two case studies have been selected for initial demonstration: medical diagnostics and climate change adaptation management.

Vito Trianni

Research director at the ISTC-CNR, studies collective intelligence in natural and artificial systems. He is the coordinator of the HACID project.

His research mainly involves collective intelligence and swarm robotics studies, with particular emphasis on the design and analysis of complex self-organising systems and distributed cognitive processes. He pioneered the domain of Evolutionary Swarm Robotics, that is, the synthesis of collective behaviours for robotic swarms through the exploitation of evolutionary robotics techniques. He is also conducting research on the analysis and design of large-scale decentralised systems, not limited to swarm robotics systems (e.g., cyber-physical and socio-technical systems). Finally, he is pursuing the development of hybrid collective intelligence, where humans and machines interact to collectively solve complex problems (e.g., decision support to medical diagnostics and policy making). Updated publications can be found on his Google Scholar page.

Nesta CCID

Nesta’s Centre for Collective Intelligence Design helps create new ways for communities to use technology to harness their insights, ideas and power to act on the problems that matter to them and create the futures they want. We design tools and projects that allow communities to respond collectively to challenges, and that help public and voluntary sector institutions strengthen trust and collaboration with citizens. We use rigorous research methods to test, learn and evaluate each solution. Our flagship Collective Intelligence Design Playbook helped to define the field and is used by practitioners around the world and we were one of the first to experiment with participatory methods to design AI systems. We have worked with organisations from the UN to the BBC. To learn more, visit nesta.org.uk/project/centre-collective-intelligence-design or email the team at collective.intelligence@nesta.org.uk
