Abstract. The Workshop on Legal Data Analysis intends to focus on representation, analysis and reasoning with legal data. Workshop organisers are: Michal Araszkiewicz, Erich Schweighofer and Bernhard Waltl. The workshop at JURIX2018 would be already the 4th.

Deadline extended until 23 November 2018!


The Workshop on Legal Data Analysis of the Central European Institute of Legal Informatics (CEILI) intends to focus on representation, analysis and reasoning with legal data in information systems from a lawyer’s and citizen’s perspective; trying to get support in mastering big data in law but also respecting privacy issues.

The pervasive use of information systems has led to tremendous success in enterprises and businesses. With a user-centric design, information systems (IS) have proven their value in today’s companies on several occasions. Most recent developments have unveiled unexpected possibilities in overcoming the retrieval constraints of access to legal knowledge. In law, the need arises for both legal databases as well as huge data volumes of cases. Market solutions are already available.

However, theoretical work and practical reflection for time-, data-, and knowledge-intensive tasks, which most of the tasks in legal science and legal practice are still highly relevant. Pre-defined formal models of legal knowledge and semantic documents allow semantics of textual and structural information with tools of Natural Language Processing, Named Entity Recognition, Network Analysis, Information Retrieval and additional analysis and measurements. This workshop particularly encourages submissions describing concrete user problems, needs and concerns in the context of legal data and legal analysis and theoretical reflection.

This workshop is intended to 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.

Participation is most welcome on all topics relevant to these research domains, including:

  • Reasoning with legal information and legislative texts (including contracts and patents)
  • Modeling and design of legal information, legislative texts, electronic contracts and SLAs
  • Usage of ontologies in information systems to support representation, analysis and reasoning on legal information
  • Analysis of the network like structure of legal systems and legislations
  • Forecast and prediction models on legal data
  • Big Data analysis of textual information In large legal text corpora
  • Access to Data and Open Data Initiatives
  • User stories and use cases of legal analysis in combination with IS
  • Predictive Coding
  • Natural Language Processing in IS
  • Multi-lingual aspects of NLP in the legal domain
  • Interoperability of logic frameworks and natural language processing
  • Drawbacks and limitations of logic frameworks, natural language processing, usage of ontologies in IS, etc.
  • Measurements, such as quantitative linguistics, and correlations on legal data
  • Information retrieval in IS, including optimization, reformulation, refinement and expansion of queries and facets
  • Semantic relations in electronic files
  • Societal impact of emerging IS technology in the legal domain
  • Argumentation mining
  • Legal interpretation modelling (including judicial interpretation and doctrinal interpretation)
  • Privacy and big data issues

We invite researchers to submit their original papers (drafts 4-10 pages, final papers: 8 pages, 2400 words) on these themes. In case of acceptance, the paper will be included in the workshop materials and later extended versions published in Jusletter IT (http://www.jusletter-it.eu).
