Welcome to ISA-17, the Seventeenth Workshop on Interoperable Semantic Annotation. This is the 2021 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 experts in the annotation 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, motion, dialogue acts, discourse relations, semantic roles, coreference, and quantification phenomena, for which the ISO organization pursues the establishment of standardised annotation methods and representation schemes, to support the creation of interoperable semantic resources.

Accepted Papers and Proceedings

The accepted papers will be published in the ISA-17 proceedings, which will be included in the ACL Anthology.

Call For Papers

Besides a main track, ISA-17 features two specialised tracks, focused on:

  1. the annotation of quantification (and quantified modification) in natural language, and
  2. the design and representation of data structures for generating visualisations of linguistically represented objects, properties, and events.

These topics are inspired by a recently started project on developing an ISO standard for the annotation of quantification (ISO/WD 24617-12, 'QuantML'), and a proposal for developing an ISO standard for the representation of visual information ('VoxML').

Both specialised tracks consist of a pre-conference on-line portion and an on-site portion during the IWCS 2021 conference in Groningen. For the pre-conference on-line portion participants are invited to take part in a shared task, submitting their commented annotations and observations for a batch of example items that are provided with documentation and guidelines of the envisaged annotation and representation schemes.

Types of Submission

The following types of submission are invited:
  • Research papers, describing original research in the area of semantic annotation; these can be either:
    • long (6-8 pages, with additional pages for references references), or
    • short (3-5 pages, plus references)
  • Project notes:
    • describing recent, ongoing or planned projects involving semantic annotation (2-4 pages including references);
    • discussing observations and analyses relating to the participation in the shared task of one of the specialised tracks (up to 4 pages), with accompanying annotations.


The ISA-17 workshop is hosted by the IWCS 2021 conference in Groningen.
