ISA-21 will be the 2025 edition of a series of joint workshops of the ACL Special Interest Group in Semantics (SIGSEM) and the International Organisation for Standardisation ISO. The latest editions were held as part of the IWCS conference 2023 in Nancy (ISA-19), and as part of the LREC=COLING 2025 conference in Turin (ISA-20).

The annual ISA workshops bring together researchers who produce or consume annotations of semantic information as expressed in text, speech, gestures, graphics, video, images, and in communicative behaviour where multiple modalities are combined. Examples of semantic annotation include the markup of time and events, dialogue acts, discourse relations, semantic roles, coreference, space and motion, and people and objects participating in activities and events.

The ISO organisation pursues the establishment and exploitation of standardised annotation methods and representation schemes in 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 semantic annotation and to critically examine and compare existing approaches and frameworks.
