The In-Use track of ESWC 2026 is looking for contributions that apply state-of-the-art semantic technologies or resources in real-world settings. Submissions to the In-Use track should primarily be focused on an application domain, and are expected to either

1. discuss the merits and challenges of using semantic technologies or resources to address the problems of that application domain or
2. detail the technical adaptations and/or improvements that are necessary to apply the semantic technologies or resources in that domain.

Moreover, submissions must demonstrate the fitness for purpose of the proposed approach, be it through use by a user community, or through a principled evaluation.

Scope

The following is a non-exhaustive list of types of submissions we encourage to the In-Use track:

• Applications of semantic technologies or resources (e.g. knowledge graphs, linked data, ontologies, neuro-symbolic techniques, knowledge graph embeddings) to implement a solution for a particular problem.
• Adaptations or enhancements of semantic technologies for ease of deployment, or interoperability with other technologies (e.g., natural language processing, Large Language Models, etc.) or other enterprise systems (e.g., relational databases).
• Descriptions of experiences integrating semantic resources such as large public knowledge graphs (e.g. Wikidata, DBpedia) into deployed applications.
• Descriptions and analyses of a concrete application problem and user requirements for applying semantic technology to tackle that problem (including scalability analysis in large scale deployment).
• Analyses and evaluations of usability and uptake of semantic technologies in a particular application domain.
• Assessments of costs and benefits of implementing, deploying, using, and managing particular semantic technologies.
• Analyses of risks and opportunities of using semantic technologies in organisations with respect to their businesses and customers.

Delineation from the other Tracks

We strongly recommend that prospective authors carefully check the calls of the other main tracks of the conference in order to identify the optimal track for their submission.

Papers that contribute novel theoretical, analytical or empirical insights to the Semantic Web, knowledge graphs or semantic technologies in general should be submitted to the Research Track.

Authors who want to present an interesting industry application but who do not want to submit a full paper should submit to the Industry Track.

Papers describing concrete resources (datasets, ontologies, vocabularies, annotated corpora, workflows, knowledge graphs, evaluation benchmarks, etc.) should be submitted to the Resource Track.

Note that Research, In-Use and Resource papers are published within the same proceedings by Springer’s Lecture Notes in Computer Science series.

Review Criteria

Papers in the In-Use track will be reviewed according to the following criteria:

• Novelty and significance of the application presented
• Relevance and impact of the contributions
• Soundness and rigour in the methodology
• Fitness for purpose of the proposed approach
• Impact of the solution / use case, particularly in demonstrating benefits of semantic technologies and promoting their adoption
• Adoption by domain practitioners and general members of the public or application in specific settings
• Clarity and quality of presentation

Important Dates

All deadlines are 23:59 anywhere on earth (UTC-12).

Submission Guidelines

• ESWC will not accept work that is under review or has already been published or accepted for publication in a journal, in another conference, or in another ESWC track. A pre-print of the article may be made publicly available by the authors in a preprint server such as Arxiv.org.
• Authors of papers must pre-submit an abstract by the abstract deadline.
• The proceedings of this conference will be published in Springer’s Lecture Notes in Computer Science series. The preprints of the accepted papers will be available openly.
• Papers must not exceed 15 pages (plus unlimited references) and be in English. Annexes will be considered to count towards the page limit.
• The review process for the In-Use track will be single anonymous (i.e., reviewers remain anonymous, while the authors’ identity is visible to the reviewers). Hence, submissions to the In-Use track should not be anonymized.
• Submissions must be either in PDF or in HTML, formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). For details on the LNCS style, see Springer’s Author Instructions. For HTML submission guidance, see the HTML submission guide.
• Authors will have the opportunity to submit a rebuttal to the reviews to clarify questions posed by program committee members.
• At least one author per contribution must register for the conference for an in-person presentation.
• Submission is done through EasyChair. When logging in, select the appropriate track.
• It is highly recommended that authors ensure access to the code, data and application during the review process, ideally by citing these research artifacts at a permanent location. See the guidelines for resources for examples and guidance on how to cite your code and datasets.
