Structured Data Across Wikimedia/Section-level Image Suggestions

This page describes the work underway to design and generate image suggestion for sections of articles and build features using those, which is currently in development by the sdaw>Special:MyLanguage/Structured Data Across Wikimedia|Structured Data Across Wikimedia team.

Section-level image suggestion is an extension of the imgsugg>Special:MyLanguage/Structured Data Across Wikimedia/Image Suggestions|article-level image suggestions feature, that recommends images for articles on contributors' watchlists that are a good match for individual sections of those articles. This work will build on the work already done on the imgsugg>Special:MyLanguage/Structured Data Across Wikimedia/Image Suggestions|Image Suggestions feature, in combination with the work currently in development about sectopics>Special:MyLanguage/Structured Data Across Wikimedia/Section Topics|Section Topics.

How it works
The project is currently experimenting with an approach based on notifications. The goal is to embed the suggestions in the user’s existing Wikipedia activities through weekly notifications, thus increasing the likelihood they will review such suggestions and add selected images as part of their current editing workflow. Contributors can choose to edit via Wikitext or Visual Editor, and can review the image and the article information in the notification.

Similarly to what already happens with the imgsugg>Special:MyLanguage/Structured Data Across Wikimedia/Image Suggestions|article-level image suggestions feature, a contributor who has at least 500 edits will receive up to two notifications per week, selected from the list of matched recent images to unillustrated sections of articles. The articles will be chosen combining the results of the Image Suggestions Algorithm, of MediaSearch and of sectopics>Special:MyLanguage/Structured Data Across Wikimedia/Section Topics|Section Topics.

Based on the information provided in the notification, the user can:
 * 1) go through their normal image addition workflow (e.g. choose to insert the image with wikitext or Visual Editor insert flow)
 * 2) * in this case, just the opportunity to review the match will be provided to the user - no additional help or feature will be provided
 * 3) click on “Review image” in the notification
 * 4) * this will redirect the user to the image on Commons
 * 5) click on “Review article” in the notification
 * 6) * this will redirect the user to the article on Wikipedia

Metrics and analytics
We are planning on measuring the following metrics, to analyze the performance of the current testing and determine whether the tool is successful:
 * 1) Number of notifications sent
 * 2) Number of image suggestions notifications opened (measuring engagement with notifications)
 * 3) Number of opt-outs (low number of opt-outs = notifications are useful)
 * 4) Number of images suggested that are added to the matched section within a month of receiving the notification
 * 5) Number of suggested images not reverted from their matched section (low revert rate = good quality of suggested matches)
