Welcome to ISA-20, the Twentieth Workshop on Interoperable Semantic Annotation. This is the 2024 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.

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.


The workshop proceedings, in the format in which they will be published in the ACL Anthology, are now available here.


The workshop program is now available here.

Presentation and Poster format:

Oral presentations of long papers may take up to 30 minutes, including at least 5 minutes for questions and discussion.
Oral flash presentations introducing posters have a length of 5 minutes. The poster boards are 90 x 150 cm and have vertical (portrait) format. Posters should be somewhat smaller than the poster boards; recommended is printing the poster in portait format with A0 size (84,1 x 118,9 cm).
