LD4LT Workshop on Linguistic Annotations on the Web

Minutes / Agenda / Brainstorming document

Detailed description

The workshop is focused on challenging issues of web annotation and to share and enhance the state-of-the-art of linguistic annotation on the web involving cross-discipline and cross-linguistic audiences. It provides background information on major community standards, their benefits and shortcomings, with the specific aim to contribute to and to consolidate an on-going discussion within the W3C Community Group Linked Data for Language Technology (LD4LT) on developing a consolidated LOD vocabulary for linguistic annotations for applications across language technology, empirical linguistics, computational lexicography, digital humanities, etc.

The numerous existing vocabularies that exist for the purpose are neither interoperable with each other, nor do they cover all relevant use cases. Since 2019, LD4LT is thus working towards the harmonization and extension of existing standards for creating, publishing, sharing, accessing and processing linguistic annotations on the web. The goals are to (a) provide a survey about standards, challenges and requirements, to (b) work towards a W3C community report that provides either best practices for annotations or extensions to existing standards, and, ultimately, to (c) inform subsequent standardization efforts.

We aim to provide a general introduction into the topic, to consolidate this discussion, and to discuss directions, goals, and concrete strategies.

List of topics

  • interoperability
  • linguistic annotation
  • linked data
  • web standards
  • knowledge graphs
  • natural language processing
  • digital methods in linguistics
  • Digital Humanities

Past events

As an LD4LT community meeting, this workshop is the first of its kind. However, the organizers have been involved in organizing numerous workshops, summer schools and conference on the topic, including:

  • Seven international workshops on Linked Data in Linguistics (LDL-2013, 2014, 2015, 2016, 2018, 2020): 40-90 participants each
  • Two Summer Datathons on Linguistic Linked Open Data (SD-LLOD 2017, SD-LLOD 2019): 40-50 participants
  • Language Resources and Linked Data tutorial (EKAW-2014)
  • Two conferences on Language, Data and Knowledge (LDK-2017, LDK-2019): 100-120 participants

This meeting builds on this experience, but is dedicated to a more narrowly defined aspect. The LD4LT community group currently has more than 100 members, but for a presence meeting, we adopt a conservative estimate about the expected number of participants (see below).



The workshop will be conducted as hybrid half-day workshop in the morning session of the [W3C Day at LDK-2021|http://2021.ldk-conf.org/post-conference-w3c-day/]</span>. On-site participation is possible for attendants of the LDK main conference, external participants (and virtual attendants of LDK) are welcome. For virtual participation, we use Zoom. Attendance is free of charge, but participants have to register at the LDK Registration Page.

The workshop is both a general assembly of the W3C community group Linked Data for Language Technology, and organized in conjunction with the COST Action Nexus Linguarum. In that sense, the format is less a classical workshop with formal paper submission but rather an informal discussion round with invited presentations, but focusing on discussion. It will be a mixture of presentations, use cases and discussion, with a focus on both providing the necessary background for harmonizing linguistic annotations on the web, and discussing the prospective directions, subtasks and possible milestones of such an enterprise as well as use cases.


We plan a four hour event 09:00 - 13:00 CET with a 30 minute coffee break 10:30 - 11:00 CET.

As for the brainstorming session, please feel free to us contribute with questions and ideas, and bring in your perspectives already during background and use case sessions: Minutes / Agenda / Brainstorming document

Who should join

We expect the mixed audience coming from the LD4LT, from Nexus Linguarum and also from outside these networks. Anyone willing to present their state-of-the-art research or participate in the discussions is kindly welcome to join as the workshop expects cross-fertilization both across the project Nexus Linguarum domains and the research coming outside the project with the view joining the project if there is an interest. Depending on Covid-19 situation we expect 15-20 on-site participants and about 50 online participants if the workshop has to be organized in a mixed mode.


The workshop is a joint activity of the LD4LT W3C and the Cost Action Nexus Linguarum. It will provide a mixture of background presentations, descriptions of use cases and requirements and open discussion.
