Workshop Overview

× DEADLINE EXTENSION! Submission due to 22nd August 2022.

About the workshop

The legal domain applies to every aspect of people’s living and evolves continuously, building a huge network of interlinked legal documents. Therefore, it is important for a government to offer services that make legal information easily accessible to the citizens, enabling them to defend their rights, auditing public procurement, or to use legislation as part of their job. It is equally important to have professionals (lawyers, judges, administrations, etc.) access legislation in ways that allow them to do their job easily (e.g., they might need to be able to see the evolution of a law over time). Despite recent efforts to make all this accessible and transparent to both citizens and the companies involved, the level of implementation in different countries and layers of public administration still makes access difficult. For this reason, in the age of the Web it is important to develop applications for citizens and professionals easily, by connecting the available legal information with other kinds of government or private sector information.

The vision of the AI4LEGAL workshop is to bring together Artificial Intelligence and practitioners to discuss the digitization of legal documents, such as legislation and public procurement data, in today’s interconnected world.


The semantic web is gradually gaining ground in the legal domain, which was previously reluctant to incorporate technology in its procedures. Additionally, novel topics are becoming more and more of interest in last years; new legislation concerning COVID19 pandemics, as well as concern regarding public procurement. Although the legal domain has always tried to stay out of the digitization that has already reached other domains, the recent pandemic and the implementation of teleworking have forced the creation of new procedures and the forced digitization of several previously existing procedures. It is time to boost the semantic web in this domain.

Audience and community

The expected audience will be researchers and practitioners from the Semantic Web area working or interested on the legal domain or in public procurement.

There is already a strong community of people interested in the topics of the workshop, that usually attend either semantic web conferences or legal domain-related conferences, such as the International Conference on Artificial Intelligence and Law (ICLAI), or the International Conference on Legal Knowledge and Information Systems (JURIX). The objective is to attract both the intersection of ISWC and these workshop, as well as people working on relevant topics (public sector employees, the legal profession and companies producing relevant software). Recent papers both in public procurement and the legal domain demonstrate the growing interest in the application of the semantic web to these domains.


The topics of interest to be covered by the workshop are the following:
  • Natural language processing techniques for legal documents
  • Legal knowledge graphs
  • Knowledge representation and reasoning techniques for legal documents
  • Explainable AI for legal documents
  • Linked data for legal documents
  • Machine learning techniques for legal documents
  • Scalable deep learning techniques for legal text analytics
  • Machine translation for legal documents
  • Question answering for legal documents
  • Chatbots for legal documents
  • Language resources for digital legal document research and development
  • National or international initiatives and digital platforms for legislation
  • National or international initiatives and digital platformas for public procurement
  • Legal Multilingualism
  • Specific application areas (legislation, judicial decisions, case law, compliance, contracts, public procurement)
