Cyras and Lachmayer on Visualization of Hajime Yoshino's Logical Jurisprudence

Vytautas Cyras, Vilnius University, and Friedrich Lachmayer, University of Innsbruck, have published Visualization of Hajime Yoshino's Logical Jurisprudence, at Trends and Communities of Legal Informatics: Proceedings of the 20th International Legal Informatics Symposium (IRIS) 2017 349 (E. Schweighofer, F. Kummer, W. Hoetzendorfer, and C. Sorge, eds., OCG, Vienna, 2017). Here is the abstract.
Hajime Yoshino’s Logical Jurisprudence (LJ) is an important concept in legal informatics. Yoshino aims for a logic-based systematization in the legal domain. He focuses on legal reasoning and systematization. Inevitably, embracing law as a whole brings us to Hans Kelsen’s Pure Theory of Law. In sum, three issues are important in LJ: logic, Kelsen and legal informatics. In this paper we aim to visualize the architecture of LJ. We suggest expanding this with legal ontologies and words. The granularity of word-phrase-sentence-text is about different methods which apply to different units.
