This work studies quantitative measures for ranking judicial decisions by the Brazilian Supreme Court [Supremo Tribunal Federal (STF)] and selecting leading cases, which are understood as those with broadness of influence on different legal fields. The measures are based on a network built over decisions whose cases were finalized in the Brazilian Supreme Court between 01/2001 and 12/2019, which were obtained by crawling publicly available STF records. Three ranking measures are proposed; two are adaptations of the PageRank algorithm, and one adapts Kleinberg’s algorithm. Such measures are compared with respect to agreement on top 100 rankings; we also analyze each robustness measure based on self-agreement under perturbation. We examine whether the resulting quantitative ranking is congenial to a qualitative intuition of what the legal community usually considers as relevant precedents. We also discuss some possible criteria of relevance in the seek for patterns that suggest how quantitative and qualitative measures would better align. The ranking of leading cases and relevant decisions improved after building decision networks without irrelevant appeals and decisions that overflow the court offers a starting point to discuss the role of STF in the Brazilian judicial system. In our last work, both versions of PageRank and Kleinberg algorithms produced different rankings and all of them were robust with respect to 10% and 20%-perturbation levels, but none of them retrieved leading cases at the top of these rankings. Then, we took a further step in the studies of the STF decision network and we introduced better filtering of network nodes guided by legal expertise on the works of the Supreme Court. We also introduced more fine-grained perturbance levels to understand the impact of such filters in the STF decision network. We concluded that after filtering low-relevance decision types, the STF decision network is still robust under 10%-perturbation, but it presents higher degradation by increasing perturbation levels. The two versions of PageRank still produce different rankings. Kleinberg’s algorithm provides a different ranking, with many relevant criminal cases. Although we improved algorithms rankings filtering decisions from the network, which represents an important methodological step, there is still room for improvement. Given that relevant decisions are well ranked after filtering out a large amount of irrelevant decisions, the results set a starting point to discuss the role of STF in the Brazilian judicial system.
RESUMOA última reformulação na grade curricular do bacharelado em Ciência da Computação (BCC) do IME-USP deu-se em 1998. Há seis anos, um grupo de alunas, alunos, ex-alunas, ex-alunos, professoras e professores do BCC iniciou um estudo com o objetivo de propor atualizações para a grade curricular do curso. Entre as principais mudanças propostas por este grupo estão a criação de trilhas e o aumento do número de disciplinas optativas eletivas, permitindo, inclusive, que os alunos cursem mais disciplinas de outras áreas e mesmo de outras universidades. Neste texto, apresentamos o processo de mudança da grade, a nova grade curricular, bem como as diferenças entre as estruturas curriculares antiga, anterior e nova. A nova grade curricular entrou em vigor no ano de 2016. É importante observar que o processo contou fortemente com a participação de alunas, alunos, ex-alunas e ex-alunos. Um efeito colateral positivo dessa participação é o aumento do envolvimento das alunas e dos alunos no curso, que pode ser observado pela criação espontânea de diversos grupos de atividades extracurriculares. Palavras-chave:Ciência da Computação; Reforma Curricular; Alumni. ABSTRACTThe last curriculum reform of the undergraduate degree Program in Computer Science (BCC) of the IME-USP took place in 1998. Six years ago, a group of BCC students, alumni, and professors began a study aiming to propose updates to the BCC curriculum. Among the main changes proposed by this group are the creation of tracks and the increase in the number of elective courses, allowing students to attend more courses from other areas and even from other universities. In this paper we present the update process of the curriculum, the new curriculum, as well as the differences between old, previous and new curricula. The new curriculum became valid in 2016. It is important to note that the process relied on the participation of students and former students. A positive side effect of this participation is the increase of the students' involvement in the Program, which can be observed by the spontaneous creation of various extracurricular activities groups.
