Scope and Topics

The first aim of this workshop is to enhance our understanding of the links between individuals, social structure, and language usage. These questions should be addressed by the detailed analysis of recently available large digital datasets, like ones collected in Twitter and other systems. These datasets include the social interactions and the utterances of a large number of individuals, which allows for the coupled analysis of the social network and language variation and change as a function of time. Our goal is to contribute to the interdisciplinary fields of computational sociolinguistics, network science, data-driven and computational approaches to language and social network. We will bring together researchers focusing on network linguistics, from different fields: machine learning, data analytics, data mining, computational modeling, large-scale graph-structured high-dimensional data, low-dimensional representations by dimensionality reduction. A second objective of 
the workshop will be to discuss about these types of methods, which follow often from a data driven approach, especially for their application to social media dataset.
 
 

Network Science Thematic Semester

The thematic semester on Network Science is organized by the DANTE Inria team (Ecole Normale Supérieure de Lyon, Université Claude Bernard (Lyon 1), CNRS, Laboratoire de l’Informatique du Parallélisme -- UMR5668), the SiSyPhe team (Ecole normale supérieure de Lyon, Université Claude Bernard (Lyon 1), CNRS, Laboratoire de Physique -- UMR5672), the Centre de Physique Théorique -- UMR-7332, the Excellence Laboratory MILYON — Mathematics and Fundamental Computer Science in Lyon, the Institute of Scientific Interchange -- (ISI) and the IXXI (Complex Systems Institute in Rhône-Alpes). 
 
This program intends to cover both the basics of and recent advances in Network Science and Data Analytics for Networks. In this program, we aim to bring together world-known experts from the fields of mathematics, physics, signal processing, computer science, social science, epidemiology and linguistic to discuss and enhance our understanding about the interaction between the structure, evolution, and coupled dynamical processes of complex networks. 
 
We welcome participants from graduate student level to the level of experts in the subject. Limited number of travelling support for students is available (through the organizers).
