Aims and Scope

The exponential increase in scientific, technical, and legal data available on the Web, including research articles, patents, standards, and technical reports, has made their large-scale semantic processing, interlinking, and knowledge extraction a central challenge for the Web community. These data sources are heterogeneous, semi-structured, and domain-specific, containing complex elements such as text, tables, equations, and diagrams that make traditional data integration and analysis difficult. Yet, they hold immense potential for advancing knowledge discovery, open science, and evidence-based innovation. As the Web evolves into a vast ecosystem of human- and machine-generated content, there is a growing need to develop scalable AI models and semantic interoperable representations that transform this fragmented information into interconnected, machine-interpretable knowledge..

In this context, the SemTech 2026 workshop focuses on methods that combine Semantic Web technologies, Natural Language Processing, Large Language Models (LLMs), and other AI technologies to model knowledge across scientific, technical, and legal domains. The workshop invites research on knowledge graph creation, semantic annotation, LLM–KG hybrid reasoning, and trustworthy AI pipelines that enhance the reliability, interpretability, and reuse of Web data. This is particularly timely as the Web community seeks robust approaches to integrate symbolic and sub-symbolic methods for managing and understanding the growing body of domain-specific knowledge on the Web.

Workshop Topics

The workshop accepts contributions in all topics related to semantic web technologies and deep learning focused (but not limited) to:

  • Data Collection
    • Leveraging LLMs for generating scientific, technical, and legal data.
    • New tools and systems for capturing scientific, technical, and legal data such as scientific articles, patent publications, etc.
    • Procedures and tools for storing, sharing, and preserving data on the Web.
    • Collecting and sharing data sets such as benchmarks, etc.
    • Pipelines and protocols to capture peculiarities from Web data.
    • Employing Semantic Web Technologies to represent and preserve sensitive data in terms of ethics, privacy, security, trust, on the Web.
  • Novel AI technologies for scientific, technical, and legal data
    • Ontologies and annotation schema to model such data.
    • Annotation, linking and disambiguation of the data.
    • Knowledge graph construction.
    • LLMs to generate metadata, vocabularies, ontologies, and semantic models for specific data.
  • Applications for patents, scientific, technical and legal data by exploiting semantic technologies
    • Exploiting knowledge graphs to drive document similarity, question answering, search etc.
    • Semantic content-based retrieval.
    • Natural language processing techniques for classification, summarization, etc.
    • Exploratory search using semantic technologies on scientific, technical, and legal data.
    • Key enabling tools (also based on LLMs) for accessing and using data on the Web.
    • Applications based on Generative AI and LLMs.
    • Lessons learned or/and use cases both from academia and industry around semantic models and LLMs for data in specific domains.

Submission

There have been changes due to the conference policy

Formatting Requirements. Submissions must be written in English, in double-column format, and must adhere to the ACM template and format (also available in Overleaf ). Word users may use the Word Interim Template. The recommended setting for LaTeX is: \documentclass[sigconf, review]{acmart}. The papers must be submitted as PDF files to EasyChair

We will consider three different submission types:

  • Full Research Papers (6-8 pages maximum) , should be clearly placed with respect to the state of the art and state the contribution of the proposal in the domain of application, even if presenting preliminary results. In particular, research papers should describe the methodology in detail, experiments should be repeatable, and a comparison with the existing approaches in the literature is encouraged.
  • Replicability/Reproducibility papers (4 pages) should involve repeating prior experiments using the original source code and datasets to analyze existing methods and their limitations. Alternatively, authors may assess the robustness of previous work by applying the original code in new contexts, such as different domains or datasets.
  • Short Papers (4 pages), should describe significant novel work in progress. Compared to full papers, their contribution may be narrower in scope, be applied to a narrower set of application domains, or have weaker empirical support than that expected for a full paper. Submissions likely to generate discussions in new and emerging areas of legal data are encouraged.

Submissions should not exceed the indicated number of pages, including any diagrams and references.

The accepted papers will be available on the Workshop website. The proceedings shall be published in a CEUR-WS.org volume, which is free of charge for ALL authors. This publication is a "Diamond Open Access" service, meaning it is also free for all readers. The proceedings will be indexed on Google Scholar, DBLP, and Scopus as for the previous workshop editions.

CHANGE TO PROCEEDINGS PUBLICATION Due to conference policy, papers accepted by the workshop will be included in the Companion Proceedings of the Web Conference 2026 which are archived in the ACM Digital Library, subject to meeting the ACM open-access, formatting guidelines, and camera-ready timeline as provided and observed by the ACM Web Conference. See the section Important update on ACM's new open access publishing model for 2026 ACM Conferences! on the conference website.

Each submission will be reviewed by three independent reviewers on the basis of relevance for the workshop, novelty/originality, significance, technical quality and correctness, quality and clarity of presentation, quality of references and reproducibility. The review process will be single-blind.
