Abstract: The emerging field of food computing tackles, among others, problems of knowledge acquisition, modeling, and processing within the culinary domain. Food-related knowledge is often implicit, contextual, or culture-dependent. Making at least part of it explicit, with some formalization, opens up possibilities to develop intelligent knowledge-based solutions to assist humans in preparing and optimizing food. An interesting and relevant problem is searching for substitutions in food recipes, a task motivated by different constraints and goals of a person, and leveraging the knowledge of dieticians and/or food technologists.

Addressing this challenge, the following questions emerge: What is relevant knowledge when it comes to food recommendations and AI-based decision support for ingredient substitution? Is there space for knowledge-based systems in the age of large language models? How to formally represent and reason about diets, allergies, and other restrictions? What food-related knowledge graphs and ontologies are there and are they useful for practical applications? In this seminar, I will share my experience from the TAISTI project (“Development of a Technology based on Artificial Intelligence for inferring SubsTitutable recipe Ingredients”, https://www.taisti.eu/), in particular ontology and knowledge graph engineering, and logical reasoning over integrated knowledge. Apart from practical challenges, I will also discuss interesting questions about the similarity of entities -- a problem that goes beyond the domain of food. I will present the entity set expansion problem and discuss recent proposals for formally describing the similarity of instances in knowledge bases and retrieving more entities ``of the same kind.
