HACID 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 (HACID-DSS) is proposed that is based on structured domain knowledge, semi-automatically assembled in a domain knowledge graph (DKG) 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) provide supporting evidence and enrich it, generating a case knowledge graph (CKG) as a refinement 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. Demonstrations are provided in two compelling case studies contributing to the UN Sustainable Development Goals: crowd-sourcing medical diagnostics and climate services for urban adaptation.

HACID aims at harnessing the hybrid collective intelligence of human experts and AI systems to address open-ended problems—i.e., problems in which the solutions are not constrained to a (predefined, limited) set of alternatives. We aim to develop a general methodology and apply it to medical diagnostics and climate services.
In medical diagnostics, the identification of a disease from a set of symptoms may be particularly complex, as it deals with a large variety of possible diseases. Climate services represent a relatively new area of decision-making but already supported by large formal and informal bodies of knowledge, demanding the integration of multiple knowledge domains into local contexts.

A promising way to improve decision making in complex open-ended problems is exploiting collective intelligence (CI). HACID aims at developing a hybrid collective intelligence decision support system capable of providing support to evidence-based decision-making, and aggregating and expanding the solutions provided by multiple experts, ultimately providing higher efficacy and efficiency, as well as higher user satisfaction, explainability and trust. The proposed system leverages complementarities between domain expertise from humans and the AI ability of reasoning on and analyzing vast amounts of data. Using a participatory approach, HACID aims at deploying an AI system capable to deal with complex, high stakes application domains and decision-making contexts.
