Motivation
The 9th Workshop on Legal Data Analysis (LDA2026) of the Vienna Centre for Legal Informatics and Benn Ibler Attorneys at Law will be held in conjunction with JURIX2026 Wednesday December 8th, 2026, Toulouse, France. It is, with interruptions, a continuation of the successful LDA workshops since 2015.
This workshop intends to focus on representation, analysis and reasoning with legal data from a lawyer’s and citizen’s perspective; trying to get support in mastering big data in law. It should be a forum for discussion of research ideas, questions and developments addressing all kind of concrete user support in processes related to the representation, analysis and reasoning on legal information and data analysis.
Short description
The focus of legal data analysis are large data corpora, like in particular the legal text corpus, but also data on case law, factual documentation, legal files, contracts, litigations, compliance, and access to justice.
The particularities of legal language have not been properly represented in traditional legal retrieval systems, giving strong importance to methods of information and data science, like citations, thesauri, classifications, knowledge graphs, ontologies and additional structural information. With Large Language Models (LLMs), all these efforts seem to be outdated as these models can master the legal language of a legal order. LLMs have greatly eased the search formulation and also the summarisation and analysis of the search results. However, inconsistencies and hallucinations remain. Thus, the “old methodology” using structural knowledge has still some relevance, in particular for improving and checking the quality of LLMs. As an example, information retrieval solves legal validity and applicability of rules much better than LLMs. The proper mix between information retrieval, formal models of semantic legal knowledge and LLMs remains a major research topic and a practical challenge, resulting in a hybrid model or a neuro-symbolic approach.
This workshop particularly encourages submissions describing concrete user problems, needs and concerns in the context of legal data and legal analysis and theoretical reflection.
Participation is most welcome on all topics relevant to these research domains, including:
- Modeling and design of legal information, legislative texts, electronic contracts etc.
- Knowledge extraction of facts, citations, concepts, classifications and legal data, also with LLMs
- Experiences of LLMs in legal search, including RAGs
- Usage of ontologies to support representation, analysis and reasoning on legal information
- Usage of semantic graphs to support representation, analysis and reasoning on legal information
- Analysis of the network like structure of legal systems
- Forecast and prediction models on legal data
- Multi-lingual aspects of NLP in the legal domain
- Measurements, such as quantitative linguistics, and correlations on legal data
- Argumentation mining
- Legal interpretation modeling (including judicial interpretation and doctrinal interpretation)
- Quality control in legal information systems
