This archive contains data and code for the analysis presented in
(Platt & Romero, 2018). This study analyzed relationships between structural
properties of WikiProject co-editor networks and the performance/efficiency
of those WikiProjects. Co-editor networks were constructed from the entire
Wikipedia edit history by creating an edge between two editors if they had
edited the same article. The performance and efficiency of a WikiProject was
determined from the history of WikiProject article quality assessments.

In addition to the co-editor network, the project included agent-based model
simulations, which did not rely on any empirical data. The code for these
simulations is included in `agent_based_model_code_git.tgz`.

The code and data for the empirical WikiProject analysis are contained in
the `wikiproject_code_git.tgz` and `wikiproject_data.tgz` files respectively.
For convenience, the co-editor networks are also included by themselves in
the `coeditor_networks.tgz` file, using adjacency list format.
Reproducing the analysis also relies on external data sources that
have been archived elsewhere, linked below.

The data and code is organized into several directories, each containing a
Readme.md file with adittional information.

## Contents

* `agent_based_model_code_git.tgz`: git repository containing code for
agent-based models. This repository includes a copy of the `logbook` module
released under the 3-clause BSD license.
* `coeditor_networks.tgz`: English-lanaguage WikiProject coeditor networks
in adjacency-list format. Node ids are Wikipedia editor ids. WikiProject ids
are mapped to titles in `wikiproject_data.tgz`.
* `wikiproject_code_git.tgz`: git repository containing code for empirical
analysis of performance and efficiency of WikiProject co-editor networks.
* `wikiproject_data.tgz`: Data sets used by empirical analysis scripts.
