The PHaSE project is focused on promoting healthier and more sustainable eating habits. While we all know that eating healthy is important for our well-being and disease prevention, there is a growing need to consider the impact of our food choices on the environment. To help guide people towards making better food choices, the project will combine two powerful tools: recommender systems and conversational agents. Recommender systems are already known for influencing users' choices and helping them make better decisions. When combined with conversational agents, which allow users to interact using natural language, the effectiveness of these recommendations can be greatly enhanced. The project will develop innovative methods that integrate natural language generation, question answering, and recommendation algorithms into a conversational agent. This agent will enable users to ask questions about the healthiness and sustainability of recipes, find sustainable ingredient substitutes, and receive personalized recommendations for healthy and sustainable recipes tailored to their needs. The system will use persuasive dialogue strategies to make the recommendations more convincing and transparent. The effectiveness of this approach will be tested through a study involving users, aiming to raise awareness and perceptions about responsible food consumption.

The InDi project aims to develop an open-source search engine that integrates concepts such as explainability, human-in-the-loop, anonymity, fairness, and inclusiveness. Technically, InDi will leverage AI and NLP to re-rank search results and provide textual explanations for these re-rankings. From a human perspective, InDi will depend on a community of voluntary reviewers and validators who will manually assess questionable AI re-rankings and either accept or reject them, enhancing InDi's knowledge base for future queries. A blockchain mechanism will ensure that the review process is both fair and anonymous. To incentivize reviewers, InDi will offer crypto-assets as rewards, initially with a purely moral value but potentially gaining extrinsic value over time, similar to Bitcoin.
