@Physikerwelt can you tell me where I can find the respective source code?

EDIT: Found it:

SuggestionsTask: Task for getting suggestions for further reading. Currently powered by full-text search based on the given page title.

https://github.com/wikimedia/apps-android-wikipedia/blob/63749f61f01b4c5eeec9f3d07c537228416e4149/app/src/main/java/org/wikipedia/page/SuggestionsTask.java

@Physikerwelt not sure if "Article-Recommendation" tag is used correctly here. That tag is for article recommendation for creation, and not for read. (which I acknowledge is not clear from the tag alone.)

The current automatic recommendation mechanism uses the MediaWikiApi ("morelike:"-query).

• Is it feasible to modify the MediaWiki API endpoint? (I guess not within our schedule)
• Can we plug in our own API to the Android app?

Clicks on article recommendations are tracked via the Analytics funnel API:

https://github.com/wikimedia/apps-android-wikipedia/blob/4f35821eee6a713afaed0fe764d12841a1e920b9/app/src/main/java/org/wikipedia/analytics/SuggestedPagesFunnel.java

SCHEMA_NAME = "MobileWikiAppArticleSuggestions";
...
    public void logSuggestionClicked(PageTitle currentPageTitle, List<SearchResult> suggestedTitles,
                                     int clickedIndex) {
        log(
                currentPageTitle.getSite(),
                "action", "clicked",
                "pageTitle", currentPageTitle.getDisplayText(),
                "readMoreList", TextUtils.join("|", suggestedTitles),
                "readMoreIndex", clickedIndex
        );
}

@mschwarzer which API is used. If the restbase is used that won't be a problem. Otherwise I'm uncertain.

The Wikipedia API with CirrusSearch extension is used:

• https://phabricator.wikimedia.org/project/profile/209/
• https://github.com/wikimedia/mediawiki-extensions-CirrusSearch
• CirrusSearch.moreLikeThis() https://github.com/wikimedia/mediawiki-extensions-CirrusSearch/blob/caa0a08bb6bfbe829abc4457c582fae68a640059/includes/CirrusSearch.php#L483
• Searcher.moreLikeTheseArticles: https://github.com/wikimedia/mediawiki-extensions-CirrusSearch/blob/d983ef40a5ea615601854a15b1263ab2dd2c228d/includes/Searcher.php#L369

Modifying CirrusSearch might not be possible, thus, I would recommend to develop a custom API extension that makes the citolytics recommendations accessible via API. Then, we can update the Android app to use our API.

Removing the backlog tag for now - let us know when we can help! :)

Removing #research-and-data as this is not officially on our board but please ping us if we can help.
