<abstract>The semantic annotation of clinical narratives is particularly challenging due to the complexity of medical discourse and the need to integrate linguistic, semantic, and domain-specific information within a unified framework. Existing schemes tend to fall into two categories: general-purpose frameworks, which offer robust linguistic modelling but lack specialised medical representation, and domain-specific schemes, which capture clinical content yet often fail to distinguish fundamental semantic types, especially eventive expressions and referential entities. To address this gap, this study proposes Med2Story Referential, a new extension of the Text2Story annotation scheme (Silvano et al., 2021; Leal et al., 2022) (based on ISO 24617-9: 2019 ) dedicated to referential entities in clinical narratives.
