Our mission is to help computational modelers develop, document, and share their computational models in accordance with community standards and good open science and software engineering practices. Model authors can publish their model source code in the Computational Model Library with narrative documentation as well as metadata that supports open science and emerging norms that facilitate software citation, computational reproducibility / frictionless reuse, and interoperability. Model authors can also request private peer review of their computational models. Models that pass peer review receive a DOI once published.
All users of models published in the library must cite model authors when they use and benefit from their code.
Please check out our model publishing tutorial and feel free to contact us if you have any questions or concerns about publishing your model(s) in the Computational Model Library.

From Population Diversity to Contact Diversity: A Network-Based Generalization of the Greenberg Index
Marco Civico | Published Tuesday, October 13, 2026This repository contains a Python simulation script for studying network-based linguistic diversity. The model extends the classic Greenberg Diversity Index by introducing diversity measures defined over social ties rather than only over population shares. It also includes two extensions: a competence-conditioned version and a multilayer version.
