Call For Papers

Third Biennial Conference on Language, Data and Knowledge
Dates: 14 June 2021 (Workshop/Tutorials day), 15-16
June 2021 (Main Conference)
Location: Zaragoza, Spain
Submission Deadline: 29 January 2021

We invite submissions to the third biennial conference on
Language, Data and Knowledge (LDK 2021), which will be held
in Zaragoza, Spain in June 2021. This conference aims at
bringing together researchers from across disciplines
concerned with the acquisition, curation and use of language
data in the context of data science and knowledge-based
applications. This builds upon the success of the inaugural
event held in Galway, Ireland in 2017 and the second LDK in
Leipzig, Germany in 2019.

Paper submission
We welcome submission of relevance to the topics listed
below. Submissions can be in the form of:

• Long research papers: 10-15 pages;
• Short research or position papers: 6-8 pages;
• Short scientific abstract submissions: be 4-6 pages.
• Short abstracts on new challenges and research ideas
(“Crazy New Ideas”): 1-4 pages

This year, we would like to propose a “Crazy New Ideas”
session that will be the occasion to present challenging
research ideas that have not yet been fully explored, or you
would like to see in ten years from now. Such ideas should
be briefly presented in the form of a short abstract of one
to four pages to initiate the discussions, which will also
be included in the conference proceedings if permitted by
the authors. This is your chance to be creative without
censorship. Reviews for these abstract will focus on the
potential of ideas to spark interesting discussions.

All submissions lengths are given including references and
optional appendices. Accepted submissions will be published
by OASIcs in an open-access conference proceedings volume
free of charge for authors.

The OASIcs layout templates to be used for submissions are
available for download from :
As the reviewing process is single-blind, submissions should
not be anonymized.

Papers should be submitted via EasyChair at the following

For each submitted paper, one author is expected to attend
the conference and present their work. There will be no
registration fee administered for LDK 2021.

Presentation format
Accepted submissions will be selected for oral or poster
presentation based on recommendations from the reviewers.
This decision will not reflect any difference in the quality
of the papers, and there will be no distinction in the
published volumes.
Authors of accepted short papers and scientific abstract are
welcome to present their work as a demo in addition to the
regular presentation.
At least one author of each accepted paper must register to
present the paper at the conference.
