===============================================================

The 10th International Joint Conference on Knowledge Graphs (IJCKG 2021, 
in cooperation with ACM/SIGAI) is an academic forum on Knowledge Graphs. 
The mission of IJCKG 2021 is to bring together international researchers 
in the Knowledge Graph community and other related areas to present 
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.

Accepted papers will be published in the ACM Digital Library as part of 
its International Conference Proceedings Series (ICPS), and will appear 
in the ACM Digital Library. Extended versions of the best papers will be 
invited for Special Issues of the Knowledge-Based Systems and Data 
Intelligence Journals.

IJCKG solicits a variety of different types of submissions. Please see 
below for further details.

Submission types
===============================================================

One of the main goals of IJCKG is to be an innovative forum that brings 
together the research community working on diverse aspects of Knowledge 
Graphs. As well as full research papers (up to 8 pages ACM format, 
excluding references), we thus additionally solicit short papers (up to 
4 pages ACM format, excluding references) relating to the aforementioned 
topics, of the following form:

+ **Resource papers** describing artefacts that are relevant in the 
context of research on Knowledge Graphs, such as Open Knowledge Graphs, 
benchmarks, ontologies, machine learning models, systems, tools, etc. 
These resources must be published online under open licenses, and the 
paper must indicate how they can be retrieved and used. (See In-Use 
papers for resources that cannot be made available online.) Such papers 
will be judged based on the potential impact of the resource on the 
research and practice of Knowledge Graphs, taking into account aspects 
such as availability, documentation, etc.

+ **Demo papers** that illustrate the functionalities of novel Knowledge 
Graph-based systems and applications. Ideally such papers incorporate 
state-of-the-art research techniques, illustrating their use in a 
practical setting. Such papers will be judged based on the maturity, 
novelty and potential impact of the system described on the research and 
practice of Knowledge Graphs.

+ **Experimental and analysis papers** that provide statistics or 
results that help to better understand (and potentially compare) key 
aspects of prominent Knowledge Graphs, as well as systems and techniques 
used in the context of Knowledge Graphs (e.g., for querying, reasoning, 
learning, etc.). Papers that reproduce (or fail to reproduce) existing 
results or claims/hypotheses are welcome here. Such papers do not 
require technical novelty, but rather will be judged based on the 
appropriateness of the experiments and analyses, as well as the 
importance and clarity of the conclusions gained. Ideally resources will 
be published online to replicate the experiments or analyses, and/or to 
provide more fine-grained data supporting the experiments or analyses.

+ **In-Use papers** that describe how Knowledge Graphs are being used in 
practice. Use-cases involving Enterprise Knowledge Graphs are welcome. 
Such papers should include some lessons learnt through the real-world 
adoption of Knowledge Graphs, and ideally should stimulate future 
research. These papers may provide a description of the Knowledge Graph 
itself, the applications that use the Knowledge Graph, the key 
techniques enabling those applications, statistics regarding the 
adoption and impact, etc. Such papers will be judged based on the impact 
of the work described, and the clarity and importance of the lessons 
learnt through the adoption described. In the case of Enterprise 
Knowledge Graphs and other commercial use-cases, it is not expected that 
resources are made available online.

+ **Vision papers** that clearly articulate important directions for 
future research on Knowledge Graphs. Such papers should identify key 
problem areas for Knowledge Graphs, and propose potential solutions or 
strategies that could be developed to address such problems. Ideally the 
papers should highlight open research questions for Knowledge Graphs, 
and should stimulate future research. These papers will be judged on how 
convincingly the vision is articulated, which ideally will include 
first-hand experiences or concrete examples and analyses to illustrate 
the problem, as well as the clarity with which the open challenges and 
research problems are described.

+ **Preliminary research papers** that describe ongoing work towards 
solving a research problem relating to Knowledge Graphs. Such papers 
must contain the typical elements of a research paper, including 
discussion of related works, the novelty of the current work (preferably 
with a hypothesis), and a description of how the work will be evaluated, 
but detailed results and conclusions are not expected. The paper may 
optionally include some preliminary evaluation results and conclusions, 
if available. Such papers will be judged in terms of novelty, potential 
impact, clarity, etc.

+ **Negative results papers** that summarise novel lines of research 
that have thus far yielded negative results (negative results for 
existing research can be submitted as an experimental/analysis paper). 
Such papers must contain the typical elements of a research paper, 
including discussion of related works, the novelty of the current work 
(preferably with a hypothesis), and an evaluation that yields negative 
results, i.e., results that do not appear to support the original 
hypothesis. In its conclusions, the paper should reflect why the results 
observed are negative in order to summarise the lessons learnt. Such 
papers will be judged in terms of clarity, novelty, and impact. Papers 
whose negative results contradict expectations are particularly welcome.

+ **Research proposals** that may include, for example, topics for 
Masters and PhD theses pursued by the author, or proposed by a 
supervisor who seeks a student or other collaborators interested in the 
topic. Such papers should provide a general context that identifies the 
research problem, related works and the gap that they leave, a 
hypothesis or concrete research questions, and some proposed research 
lines in order to test the hypothesis or address the research questions, 
including strategies for evaluation.

+ **Short research papers** that summarise research results (i.e., 
concise versions of full research papers).

All such papers should be clearly written, technically sound, and 
include discussion of related works. Authors should clearly indicate in 
the abstract and the introduction what type of paper they are 
submitting, for example, adding a phrase "In this vision paper, we ...".

Submission
===============================================================

Submissions to IJCKG 2021 should describe original work on Knowledge 
Graphs. IJCKG 2021 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. arXiv.org) or workshops papers 
without formal proceedings are not considered prior publications. In 
such cases, IJCKG 2021 authors are not precluded from submitting papers 
on the same topic by the same authors.

Full research papers submitted to IJCKG 2021 are expected to present 
their claimed research contribution, with clear evidence to support 
their claims. Short papers are expected to satisfy the criteria for the 
particular submission type (as described previously).

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; papers will also be judged according 
to the criteria specified for the submission type.

IJCKG 2021 submissions are not anonymous.

Submissions must be in PDF format, using the latest ACM Proceedings 
Format with the default 9pt font (see sample-sigconf.tex or Interim 
layout.docx from https://www.acm.org/publications/proceedings-template). 
Regular 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 for which authors do not 
register and present may be excluded from the proceedings.

Papers can be submitted electronically via EasyChair 
(https://easychair.org/conferences/?conf=ijckg2021).

Accepted papers will be published in the ACM Digital Library within its 
International Conference Proceedings Series (ICPS).
