Była ona spowodowana rozwojem przestępczości zorganizowanej, dużą liczebnością i skomplikowaną strukturą grup przestępczych oraz transgranicznym charakterem przestępstw, w czym przodowała włoska
As early as in 2009, Gartner predicted that Social Network Analysis (SNA) could be an important tool for detecting business patterns or disruptions and a source of new unprecedented insights for organisations. Today, SNA-based tools, as components of advanced analytic platforms (including predictive platforms), become indispensable for defining long-term strategies and managing
I recently met Mrs. Claus at the INFORMS Annual Meeting, where we got to talking about the social network analysis session she’d just attended. It turns out Mrs. Claus and I are both fans of a book by Alex Pentland, Social Physics: How Social Networks Can Make Us Smarter. Apparently

During my time there,
