Formal Concept Analysis, as a mathematical tool, has been applied successively in diverse fields such as data mining, conceptual modeling, social networks, software engineering, and the semantic web, to cite but a few. The stability is one of the hardest to compute interestingness measures of formal concept. In this talk, we discuss the issue of stability computation efficiency. Then, we highlight the link with the efficient computation of minimal transversals. The latter has been shown to have a countless number of applications in nearly all the fields of computer Science. Then, we present some of the applicative cases, e.g., Vanets, Smart cities, Influencers in Social networks, Data warehouses, etc.
We conclude by presenting the thriving challenges of mining the minimal pattern in the era of Big Data. We both stress on theoretical issues as well as on applicative cases.
Sadok Ben Yahia has been a Professor at the Computer Sciences department of the Faculty of Sciences of Tunis since October 2013. He obtained his Habilitation to lead researches in Computer Sciences from the University of Montpellier in April 2009. His experience in teaching, in Computer Science and Information Systems is around 20 years. He has worked for 3 years as a trainer at a professional educational center, 2 years as a teaching assistant at the Faculty of Sciences of Tunis, 7 years as assistant professor and 4 years as an associate professor. Since 2013, he holds the position of full professor at the same academic Institution. Besides his academic responsibilities, he has participated in several administrative tasks such as student’s projects coordinator and he has been the head of the Computer Science department at the Faculty of Sciences of Tunis for 3 years (2011-2014).
Currently he is the Director of the the Research Laboratory LIPAH (50 permanent members, 55 PhD Students) and his research interests mainly focus on combinatorial aspects in Big Data and their applications to different fields, e.g., Data mining, Social Computing, information aggregation & dissemination in smart cities.
He has supervised 21 PhD Computer Science Students and more than 50 master students. A selected list of his publications is shown at a glance through his DBLP web site http://dblp.uni-trier.de/pers/hd/y/Yahia:Sadok_Ben. The latter witnesses more than 38 international journals and 160 international conference papers: https://scholar.google.com/citations?user=uJwhmiUAAAAJ&hl=fr.
He is currently a member of the steering committee of the International Conference on Concept Lattices and their Applications (CLA) as well as of the International French Spoken Conference on Knowledge Extractions and Management.
