одржаће др Марија Миторовић Данкулов (Лабораторија за примену рачунара у науци, Центар за изучавање комплексних система, Институт за физику у Београду).

Апстракт:

Collective knowledge building is an example of cooperative human dynamics, which requires meaningful and logically coordinated interactions, and as such it represents a challenging problem to physics and social dynamics modeling. Question and Answers (Q&A) sites are an excellent example of a human dynamics system where knowledge advances trough a collaborative problem solving. In this talk we will demonstrate how dynamics of collective knowledge building can be studied in a quantitative manner using methods and tools from statistical physics and complex network theory [1]. Specifically, we will combine empirical analysis and a two-scale dynamics model and show that this process occurs as a collective phenomenon in a large network of actors and artifacts. This emergent behavior will be quantified trough the analysis of the characteristic self-organizational patterns, topological properties of evolving networks and measuring of advancement of knowledge in time. Our results show that the level of individual expertise plays a substantial role in this self-organized dynamics by influencing both the structure of interacting networks and the temporal patterns of knowledge advancement.
