Sharp transition towards shared vocabularies in multi-agent systems

- 9 September 2005
A microscopic model of communicating autonomous agents performing language games without any central control is introduced and it is shown that the system undergoes a disorder/order transition, going through a sharp symmetry breaking process to reach a shared set of conventions.
The Twitter of Babel: Mapping World Languages through Microblogging Platforms

It is shown that available data allow for the study of language geography at scales ranging from country-level aggregation to specific city neighborhoods, and highlights the potential of geolocalized studies of open data sources to improve current analysis and develop indicators for major social phenomena in specific communities.

Topology Induced Coarsening in Language Games

- 6 December 2005
It is highlighted that in low dimensions consensus is reached through a coarsening process that requires less cognitive effort of the agents, with respect to the mean-field case, but takes longer to complete.
Quantifying the effect of temporal resolution on time-varying networks
This work quantifies the impact of an arbitrary Δt on the description of a dynamical process taking place upon a time-varying network, and focuses on the elementary random walk, and puts forth a simple mathematical framework that well describes the behavior observed on real datasets.
Cultural route to the emergence of linguistic categories

- PsychologyProceedings of the National Academy of Sciences
- 15 March 2007
This work addresses the question of whether categories simply mirror an underlying structure of nature or instead come from the complex interactions of human beings among themselves and with the environment by modeling a population of individuals who co-evolve their own system of symbols and meanings by playing elementary language games.
Nonequilibrium dynamics of language games on complex networks.

- 6 July 2006
An extensive study of the naming game dynamics on complex networks is presented, that can be considered as the most natural topological embedding for agents involved in language games and opinion dynamics.
Mapping the NFT revolution: market trends, trade networks, and visual features
- Matthieu Nadini, Laura Alessandretti, F. D. Giacinto, Mauro Martino, L. Aiello, A. Baronchelli
- Computer ScienceScientific reports
- 1 June 2021
This work analyzes data concerning 6.1 million trades of 4.7 million NFTs between June 23, 2017 and April 27, 2021 and finds that sale history and, secondarily, visual features are good predictors for price.
#Bigbirds Never Die: Understanding Social Dynamics of Emergent Hashtags
This is the first study on the lifecycle of hashtag adoption and use in response to purely exogenous shocks and proposes a "conversational vibrancy" framework to capture dynamics of hashtags based on their topicality, interactivity, diversity, and prominence.
Random walks and search in time-varying networks.
- N. Perra, A. Baronchelli, D. Mocanu, B. Gonçalves, R. Pastor-Satorras, Alessandro Vespignani
- MathematicsPhysical review letters
- 13 June 2012
This work considers a model for time-varying networks created from the activity potential of the nodes and derives solutions of the asymptotic behavior of random walks and the mean first passage time in undirected and directed networks.
