Research:Modeling monthly active editors

Terms

Editor Classes

Monthly Active Editors (MAE)

Editors who save at least 5 revisions within one month.

New Active Editors (NAE)

Newly registered users who save at least 5 revisions in the month that they registered.

Surviving New Active Editors (SNAE)

New Active Editors from the previous month who continued to make at least 5 edits in the current month.

Recurring Old Active Editors (ROAE)

Non-new Active Editors from the previous month who continued to make at least 5 edits in the current month.

Reactivated Editors (RAE)

All other active editors who (1) were not active in the previous month and (2) were not a Newly registered user in the current month.

Basic equation

${\text{MAE}}_m={\text{NAE}}_m+{\text{SNAE}}_m+{\text{ROAE}}_m+{\text{RAE}}_m$

Rates

New Editor Activation Rate (NEAR)

The proportion of Newly registered users who save at least 5 revisions in the current month

New Active Survival Rate (NASR)

The proportion of New Active Editors the previous month who save at least 5 revisions in the current month

Old Active Survival Rate (OASR)

The proportion of Active Editors from the previous month (who were not Newly registered users) who save at least 5 revisions in the current month

Expanded equation with rates

${\text{NAE}}_m={\text{NRU}}_m\times {\text{NEAR}}_m$

${\text{SNAE}}_m={\text{NAE}}_{m-1}\times {\text{NASR}}_m$

${\text{ROAE}}_m=({\text{SNAE}}_{m-1}+{\text{ROAE}}_{m-1}+{\text{RAE}}_{m-1})\times {\text{OASR}}_m$

${\text{MAE}}_m={\text{NRU}}_m\times {\text{NEAR}}_m+{\text{NAE}}_{m-1}\times {\text{NASR}}_m+({\text{SNAE}}_{m-1}+{\text{ROAE}}_{m-1}+{\text{RAE}}_{m-1})\times {\text{OASR}}_m+\text{RAE}$

Analysis

Comparison with legacy definition

In order to explore the implications of the relatively simplistic definition of active editor used in this model (5 revisions to any page), we compare counts of active editors with those generated by the historical definition (5 revisions to countable pages).

• dump ns=0 -- Legacy definition based on XML dump processing within wikistats. Does not include edits to deleted pages and also filters by countable pages
• archive ns=0 -- All edits to pages in the article namespace (ns=0) count.
• archive ns=all -- All edits to any page count. This is the definition used in the analysis above.
