FIRST CALL FOR PAPERS ————————————- ISA-21, 2025 Joint ACL - ISO Workshop on Interoperable Semantic Annotation Workshop at the 2025 International Conference on Computational Semantics (IWCS 2025), Düsseldorf, Germany, September 22-24 Workshop date: Wednesday, September 24 Venue: Haus der Universität, Düsseldorf Submission deadline: June 13, Website: https://sigsem.uvt.nl/isa21/ 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. SUBMISSIONS Topics for submissions include, but are not limited to: * methodological aspects of semantic annotation * design and evaluation of semantic annotation schemas * innovative methods for automated and manual annotation * integration of semantic annotation and other linguistic annotations * considerations for merging annotations of distinct phenomena * multi-layered annotations and representations * semantic annotation, representation, and their interrelatedness * context-aware annotation learning * levels of granularity in annotation schemes * use of context in semantic annotation procedures * uncertainty and ambiguity in semantic annotations * semantic annotation and ontologies * comparison of semantic annotation schemes * alternative approaches to the syntax and semantics of annotations * annotator agreement and other metrics for evaluating semantic annotations * qualitative evaluation of semantic annotations * experiments in semantic annotation * applications of semantic annotation * best practices for semantic annotation procedures * application and evaluation of standards for semantic annotation * language- or application-specific aspects of semantic annotation * capturing semantic information in images and video * issues in the annotation of specific domains of semantic information, such as: - events, states, processes, circumstances, facts - relations in discourse and dialogue - time, space and motion - modality, polarity and factuality - quantification and modification - coreference relations - semantic roles and predicate-argument structures - reference and named entities - attribution, sentiment, attitudes and emotions SUBMISSION DETAILS: We invite two types of submission: 1. Research papers, describing original research; these can be either: a. long (6-8 pages, with additional pages for references if needed) or b. short (3-5 pages plus references); Accepted long papers are allowed one additional page of content to accommodate review comments. 2. Project notes, describing recent, ongoing or planned projects (3-5 pages including references). Submission of papers is in PDF form to the IWCS/ISA-21 submission page. All submissions should be formatted following the instructions on the IWCS 2025 website, which will be available soon. Reviewing will be double blind, so please make sure to anonymise your submission.
