The 5th International Conference on Ontologies and Knowledge Graphs 2026 (ICOKG 2026) aims to be an open forum for communication between students and researchers who carry out initial, intermediate, and final research on topics in graph applications, knowledge graphs, machine learning, deep learning, semantic web, natural language processing, data science applications, optimization in Artificial Intelligence Systems, and conference-related topics. We invite researchers in these areas of interest to submit contributions written in Spanish or English.
This 5th edition will be held at the Faculty of Computer Sciences of the Benemérita Universidad Autónoma de Puebla, Mexico on September 25, 2026. In order for the authors to attend the conference, we maintain hybrid participation.

Submission Process
All papers must be submitted in electronic format as PDF files before the submission deadline.
All papers are subject to a double-blind review process by three members of the program committee. We evaluated originality of the work, quality in content, innovation, and contribution to the state of the art. They should not include information that clearly identifies the authors or citations.
They must be not simultaneously submitted to another journal or conference, nor previously published. They will be screened using plagiarism detection tools.
A paper must be submitted via the CMT online submission system:

The Microsoft CMT service was used for managing the peer-reviewing process for this conference. This service was provided for free by Microsoft and they bore all expenses, including costs for Azure cloud services as well as for software development and support.
Submission and acceptance implies that at least one author is willing to register and present the work.
The original accepted works written in Spanish will be published as chapters of a book with ISBN (previous.html). All papers must meet the ethical and quality criteria of the publisher.
All articles accepted written in English will be published by 
The published papers with the highest evaluations will be invited to participate in a special issue, which will be submitted to a double-blind review process, for publication in the IJCOPI journal (ISSN:2007-1558). The papers accepted for the special issue must be written in English and extended at least a 40%.
IJCOPI is an international electronic scientific journal that publishes quality articles from different areas of knowledge related to computer science and combinatorial optimization problems. IJCOPI is recognized and indexed in SECIHTI, Web of Science, SciELO, Redalyc, LatIndex, DBLP, EBSCOhost, ProQuest, DOAJ, Google Scholar, among others (https://www.ijcopi.org/ojs/indexing).
