Title: Between Words and Worlds: Natural Language, Ontology, and the Challenge of Ground Truth

Abstract: This lecture explores the tension between ontological modeling and human language semantics, focusing on the challenges of transforming text into ontology-based knowledge representations. 
Using examples from the biomedical domain, the lecture encompasses three use cases, (i) the mapping of multilingual terms and expressions to domain ontology IDs, (ii) the construction of interoperable knowledge graphs from text, and (iii) the filling of pre-defined templates.
A central theme is the difficulty of establishing reliable ground truth through guideline-based annotation, particularly the  assignment of ontology codes to text spans, as well as the specification of relations between them. Different, yet semantically plausible, representations can diverge structurally, raising critical questions about what constitutes a “correct” annotation.
