Call for Papers

The 12th International Joint Conference on Knowledge Graphs (IJCKG 2023) is a premium academic forum on Knowledge Graphs. The mission of IJCKG 2023 is to bring together international researchers in the Knowledge Graph community and other related areas to present their innovative research results or novel applications of Knowledge Graphs. IJCKG has evolved from the Joint International Semantic Technology Conference (JIST): a joint event for disseminating research results regarding the Semantic Web, Knowledge Graphs, Linked Data and AI on the Web.

Submission types

One of the main goals of IJCKG is to unify the research community working on diverse aspects of Knowledge Graphs. As well as regular research papers (up to 8 pages ACM format, excluding references), we thus additionally solicit short papers (up to 4 pages ACM format, excluding references) that summarize research results (i.e., concise versions of full research papers).

In addition to regular papers, this year IJCKG 2023 will call foster research papers in the following topics chaired by the following area chairs:

  1. Representation and Reasoning
    (area chair: Markus Kroetzsch, TU Dresden, Germany)
    This area focuses on logical and symbolic approaches for representing and processing graph-based knowledge, including but not limited to ontologies, existential rules, description logics, logic programming, and constraint programming.
  2. Database
    (area chair: Jan Hidders, Birkbeck, University of London, UK)
  3. Information Retrieval
    (area chair: Shubham Chatterjee, University of Glasgow, UK)
  4. Natural Lanauage Processing
    (area chair: Peng Liu, Norwegian University of Science and Technology, Norway)
    This area focuses on knowledge and data extraction from massive textual contents and utilizing semantics and Natural Language Processing for Knowledge Graph development and applications in various domains, including multimedia, e-commerce, finance and healthcare, etc.
  5. Machine Learning
    (area chair: Lemei Zhang, Norwegian University of Science and Technology, Norway)
    This area focuses on theoretical and practical aspects of using machine learning algorithms and deep neural networks for a wide range of Knowledge Graph related topics, including but not limited to knowledge engineering, big knowledge, big data analytics, statistics, machine learning, pattern recognition, data mining, knowledge visualization.


Submissions to IJCKG 2023 should describe original work on Knowledge Graphs. IJCKG 2023 will not accept submissions that are under review for or have already been published or accepted for publication in a journal or another conference (*).

* Non peer-reviewed documents such as theses, technical reports, publications on preprint servers (e.g., or workshops papers without formal proceedings are not considered prior publications. In such cases, IJCKG 2023 authors are not precluded from submitting papers on the same topic by the same authors.

Full research papers submitted to IJCKG 2023 are expected to present their claimed research contribution, with clear evidence to support their claims.

All submissions will be reviewed by at least three members of the Program Committee of the Research Track. These anonymous reviewers will judge each paper’s relevance to the conference, technical soundness, and the readability of the submission.

IJCKG 2023 submissions are not anonymous.

Submissions must be in PDF format, using the latest ACM Proceedings Format (two-column) with the default 9pt font (see sample-sigconf.tex or Interim layout.docx from

Regular research paper submissions must be no longer than 8 pages, excluding references. Short paper submissions must be no longer than 4 pages, excluding references. Unlimited additional pages may be used for references. Submissions that exceed this limit or that do not follow the indicated format may be rejected without review.

At least one author of each accepted paper must register for the conference and present the paper there.

Papers can be submitted electronically via EasyChair. (select a track from regular research papers or foster research papers for five areas).

Papers for which authors do not register and present may be excluded from the proceedings.
