Digital Humanist

I focus on knowledge extraction and ontological modeling of how people make sense of the world, and represent it in machine readable format.

Post‑doctoral researcher at the University of Bologna, working in Knowledge Representation, the Semantic Web, and AI. I build ontologies that formalize commonsense knowledge: moral and cultural values, emotions, social norms, and embodied cognition.

Values Ontology import schema

Values Ontology

Moral & cultural values — modular ontology

A modular ontology of moral and cultural values, integrating Schwartz's Basic Human Values, Graham and Haidt's Moral Foundations Theory, and Curry's Moral Molecules. Each value is modeled as a conceptual frame, aligned to DOLCE, and built with reusable Ontology Design Patterns as part of the Framester knowledge graph.

Emotion Frame Ontology schema

Emotion Frame Ontology (EFO)

Emotions as semantic frames

An OWL, frame-based ontology that treats emotions as semantic frames with roles capturing the different facets of emotional experience. EFO integrates multiple emotion theories as cross-linked modules and supports multimodal datasets, including emotional speech and facial expression.

ISAAC

Image schemas & embodied cognition

The Image Schema Abstraction And Cognition modular ontology formalizes Image Schemas — dynamic conceptual building blocks arising from recurring sensorimotor interaction with the physical world — and integrates them with linguistic and factual knowledge.

Knowledge graph extracted from a sample sentence

Ethics in the Flesh

PhD thesis — values, emotions & embodied cognition

An explainable detector, built on the FRED tool, that exploits knowledge graph patterns to extract emotions, values, and image schemas from text and infer how they combine. The example above is generated automatically from the sentence “The police finally stopped the awful killer.”

Dungeons and Dragons ontology

D&D 5e Ontology

Side project — knowledge graph for tabletop rules

A knowledge graph formalizing the Dungeons & Dragons 5th edition rule system, built out of genuine nerd necessity: character bonuses, monster stats, and rules, all queryable in one place.

About

Hi, I’m Stefano. I’m a Digital Humanist and currently a post-doctoral researcher at the University of Bologna. My main research areas are Knowledge Representation, the Semantic Web, and AI — with a particular focus on emotions, moral and cultural values, commonsense knowledge, social norms, and embodied cognition.

I was born in Turin, Italy, in 1993. An early interest in language and semantic technologies led me to Alma Mater Studiorum in Bologna, where I graduated in Linguistics Sciences with a thesis on Post-truth, populism and knowledge extraction — A frame semantics approach to Indirect Hate Speech. My PhD thesis in Digital Humanities, Ethics in the Flesh — Formalizing Moral Values with Frame Semantics and Embodied Cognition, focuses on cognitive semantics and the formalization of moral values through frame semantics and embodied cognition.

I firmly believe in empathy: the cognitive, imaginative ability to put oneself in someone else’s shoes. The unknown is just an entity not yet framed in a network of meaningful semantic relationships — and every conversation, personal or professional, is a chance to practice framing it.
