Description of the workshop

The workshop series on Natural Language Processing (NLP) for Computer-Assisted Language Learning (NLP4CALL) is a meeting place for researchers working on the integration of Natural Language Processing and Speech Technologies in CALL systems and exploring the theoretical and methodological issues arising in this connection. The latter includes, among others, insights from Second Language Acquisition (SLA) research, on the one hand, and promote development of “Computational SLA” through setting up Second Language research infrastructure(s), on the other.

The intersection of Natural Language Processing (or Language Technology / Computational Linguistics) and Speech Technology with Computer-Assisted Language Learning (CALL) brings “understanding” of language to CALL tools, thus making CALL intelligent. This fact has given the name for this area of research – Intelligent CALL, ICALL. As the definition suggests, apart from having excellent knowledge of Natural Language Processing and/or Speech Technology, ICALL researchers need good insights into second language acquisition theories and practices, as well as knowledge of second language pedagogy and didactics. This workshop invites therefore a wide range of ICALL-relevant research, including studies where NLP-enriched tools are used for testing SLA and pedagogical theories, and vice versa, where SLA theories, pedagogical practices or empirical data are modeled in ICALL tools.

The NLP4CALL workshop series is aimed at bringing together competences from these areas for sharing experiences and brainstorming around the future of the field.

We welcome papers:

  • that describe research directly aimed at ICALL;
  • that demonstrate actual or discuss the potential use of existing Language and Speech Technologies or resources for language learning;
  • that describe the ongoing development of resources and tools with potential usage in ICALL, either directly in interactive applications, or indirectly in materials, application or curriculum development, e.g. learning material generation, assessment of learner texts and responses, individualized learning solutions, provision of feedback;
  • that discuss challenges and/or research agenda for ICALL
  • that describe empirical studies on language learner data.

This year a special focus is given to work done on second language vocabulary and grammar profiling, as well as the use of crowdsourcing for creating, collecting and curating data in NLP projects.

We encourage paper presentations and software demonstrations describing the above-mentioned themes primarily, but not exclusively, for the Nordic languages.

Submission information

This year we will use the NLP4CALL 2021 stylesheet for submissions. The author kit, containing LaTeX templates as well as Word template, can be downloaded from here:

Authors are invited to submit long papers (8-12 pages) alternatively short or demo papers (4-7 pages), page count not including references. Please indicate one relevant paper type at submission time. Only PDF files will be accepted. Submissions will be managed through the electronic conference management system EasyChair. Final camera-ready versions of accepted papers will be given an additional page to address reviewer comments.

Papers should describe original unpublished work or work-in-progress. Every paper will be reviewed by at least 2 members of the program committee. As reviewing will be blind, please ensure that papers are anonymous. Self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ...", should be avoided. Instead, use citations such as "Smith previously showed (Smith, 1991) ...". Submissions will be judged on appropriateness, clarity, originality/innovativeness, correctness/soundness, meaningful comparison, significance and impact of ideas or results.

All accepted papers will be collected into a proceedings volume to be submitted for publication in the NEALT Proceeding Series (Linköping Electronic Conference Proceedings) and, additionally, double-published through ACL anthology, following experiences from previous workshops, e.g. the 9th NLP4CALL.

IMPORTANT: For licensing reasons, all camera-ready papers must include the following sentence as an unmarked (unnumbered) footnote on the first page of the paper: This work is licensed under a Creative Commons Attribution 4.0 International Licence. Licence details:

NEW: Research note session (expression of interest)
Following last year's success, we continue with a research notes session this year. The research notes session is an opportunity to present and discuss ideas, projects and work-in-progress and is aimed at two different audiences: MA/PhD students and senior researchers. Each student is paired with a senior researcher to discuss their ideas. Senior researchers are not paired.

If you want to participate in the research notes session, please send an email to David Alfter (david dot alfter at gu dot se) with the subject line NLP4CALL 2021 research notes including the title of the presentation, the presenter, whether the presenter is an MA/PhD student, and a short (50 words) description of the talk. The deadline for expressions of interest coincides with the paper submission deadline (March 26) but the notification of acceptance is later (April 27). Research notes presentations are not included in the proceedings of the workshop.

The workshop series has been previously financed by the Centre for Language Technology (University of Gothenburg), the SweLL project (University of Gothenburg) and the Swedish Research Council's conference grant. Currently the funding comes from Språkbanken-Text and the L2 profiling project.

For the past nine years we successfully co-located the NLP4CALL with the two major Language Technology events in Scandinavia, SLTC and NoDaLiDa, thus making this workshop an annual event. We intend to continue this tradition. Through this workshop, we intend to profile ICALL research in Nordic countries and to provide a dissemination venue for researchers active in this area.

ICALL-relevant mailing lists

There are two mailing lists that spread ICALL-relevant information: one run by EuroCALL/CALICO SIG-ICALL group ( // and the other one run by BEA-workshop organizers ( We encourage you to join them to be updated of the events, publications and discussions in the area

  • To join EuroCALL/CALICO list, contact Mathias Schulze ( . You can freely write to the EuroCALL/CALICO list when you want to disseminate some call for papers/information or ask questions.
  • To join BEA-list, contact Ekaterina Kochmar ( . BEA-mailing list spreads information in a digest form approx 4 times a year.
