Welcome to ISA-22, the Twenty-second Workshop on Interoperable Semantic Annotation and Representation. This is the 2026 edition of a series of joint workshops of the ACL Special Interest Group on Computational Semantics (SIGSEM) and ISO TC 37/SC 4 (Language Resources) WG 2: Semantic annotation and representation.
These workshops bring together researchers who produce or consume annotations of semantic information as expressed in text, speech, gestures, graphics, video, images, and in multiple modalities combined. Examples of semantic annotation include the markup of events, time, space, dialogue acts, discourse relations, semantic roles, coreference, quantification, visualisation and motion, and people and objects participating in activities and events. The ISO organization pursues the establishment of standardised annotation methods and representation schemes for these and related areas, in support of the creation of interoperable semantic resources.
The ISA workshops provide a forum for researchers to identify and discuss challenges in effective manual or automatic semantic annotation, and to critically examine and compare new and existing approaches and frameworks.
