Поштоване колегинице и колеге,

Позивам вас на SCL семинар који ће у понедељак, 15. септембра 2014. 
године у 14:00 у читаоници библиотеке Института за физику одржати 
Босиљка Тадић (Одеск за теоријску физику, Институт Јожеф Штефан, 
Љубљана, Словенија). Наслов семинара је:

Physics of Online Social Interactions: Quantitative Study of Collective 
Phenomena

Abstract:

In recent years, interdisciplinary research of massive online 
communication data contributed to the birth of quantitative social 
science; these research activities provided evidence for the emergence 
of new collective phenomena on the Web, from sharing common emotion to 
coordinated efforts and cooperation leading to the collective knowledge. 
The source of all these phenomena is in human-to-human interactions with 
shared ``values'', where multiple factors such as the subject of 
communications, motivation to cooperate as well as technology that 
enables (or limits) it play a significant role. In this 
multidisciplinary strategies, the concepts of statistical physics are of 
fundamental importance. Firstly, physics theory provides with 
understanding the underlying stochastic processes through which the 
collective behavior arises from interactions at microscopic scale, and, 
secondly, the ways to quantify the emergent phenomena in analogy to the 
complex dynamical systems in the physics laboratory.
In this seminar, we illustrate some of the potentials of this approach 
in the actual case of the online chats data that concern a specific 
content (cognition). In the analysed example, the concepts of 
non-equilibrium statistical physics are complemented with the methods of 
text analysis and graph theory. Besides, an agent-based model of the 
online chat systems with an emotional robot is designed in order to 
explain the underlying dynamics further and demonstrate the 
potentialities to manage the collective behaviors by changing the 
parameters or actions at the microscopic level.

Срдачан поздрав,
Марија Митровић
