IWSS-26: International Workshop on Structures to Stories: Multilingual NLP for Semantic Structured Data The 25th International Semantic Web Conference Bari, Italy, October 25-26, 2026

Despite recent advances in LLM-based pipelines, the core multilingual Natural Language Processing (NLP) and Natural Language Generation (NLG) challenges of mapping between structured data and natural language, especially in low-resource and long-tail settings, remain largely unsolved and under-represented within the Semantic Web community.

The International Workshop on Structures to Stories: Multilingual NLP for Semantic Structured Data (IWSS) brings together researchers and practitioners advancing multilingual methods to (i) extract structured representations from text and (ii) generate faithful answers, verbalisations, explanations, and narratives grounded in structured evidence.

IWSS emphasises robust extraction, data-grounded generation, and realistic multilingual evaluation, with particular interest in under-represented languages, long-tail entities, and culturally specific concepts.

We invite full and short papers, position and negative-result papers, datasets, system demos, and resource papers. Topics include faithful multilingual verbalisation and summarisation, entity extraction and linking, schema/ontology alignment, and low-resource benchmarks and evaluation, among others.

Submission Guidelines

All papers must be original and not simultaneously submitted to another journal or conference.

• Submission site: EasyChair
• Format: PDF, using the CEUR-WS (CEURART) template
• Page limits (references excluded):
  • Full research papers: 8–12 pages
  • In-Use and Experience papers: 8–12 pages
  • Short research papers: 4–6 pages
  • System/Demo/Position papers: 4–6 pages
• Repositories: Authors are strongly encouraged to submit accompanying repositories (e.g., code, data, and models) in accordance with FAIR principles. Such materials should be made available via GitHub or a comparable publicly accessible platform.

List of Topics

Topics of interest include (but not limited to):

• Multilingual data-to-text (grounded verbalisation/explanations) and text-to-data (Information Extraction/Semantic Parsing, Entity Linking/normalisation)
• Cross-lingual schema/ontology alignment and lexicalisation
• Faithfulness/robustness for structured data NLP/NLG
• Low-resource benchmarks, datasets, and evaluation for structured data
• Limitations of current metrics in evaluating NLG outputs
• Analysis of biases introduced in data-to-text and debiasing solutions
• Data-to-text solutions for data sources containing long-tail entities

Publication

IWSS-26 proceedings will be published in CEUR Workshop Proceedings.
