Page Previews/GreekCatalanTest

''We ran a test where hovercards were turned on by default for Greek and Catalan Wikipedia for a period of 4 months. We have both quantitative and qualitative data for this experiment.''

Qualtrics Survey Results
In April of 2015, hovercards were rolled out to all users on Catalan and Greek Wikipedias. They also continued to be a beta feature on english and other wikipedias. During this time, a survey was shown to all hovercards users using a banner recruitment. There were over 1,700 responses, heavily dominated by non-logged in users on Catalan and Greek and logged in users (probably mostly editors) on English. Below are the aggregated results

Questions 2-6 are the qualitative text answers to whatever the user chose for open feedback. We cannot share these answers on wiki, as they have not been vetted to remove potentially personally identifiable information.

Here are some random, contiguous sample rows from those answers:
 * positive feedback:
 * bug:
 * other problem:


 * suggestion for improvement:

Known & documented issues:

 * Cutting sentences randomly - tracked in https://phabricator.wikimedia.org/T67845
 * Info in parenthesis ignored - tracked in https://phabricator.wikimedia.org/T91344
 * Period problem with TextExtracts  (send email to Gergo and Prateek)
 * Hovercards not going away - fixed in https://phabricator.wikimedia.org/T143051

Unknown and need more information:

 * Text alignment issue in certain scripts
 * Disambiguation text showing in some cases - this is when a page is just using plain indented/italic text instead of a template (e.g.). Or, if the hatnote template doesn't include.
 * Half sentences are annoying, people want more text - tracked in https://phabricator.wikimedia.org/T67845
 * People are unhappy with animation speed, some want it faster, some slower (replicating the existing Reference Tooltips options, would be best) - implemented as setting of hovercards, more info here Extension:Popups

Known and hard to solve for

 * Issues with PageImages (…) - tracked in https://phabricator.wikimedia.org/T132605
 * Map shown without dot (This should be fixed once Max and Yuri are done with the tile server)
 * Reference hovercards (user and special pages too) (Prateek and Bene* are working on a restructure) - for future implementation
 * Sub-section links (TextExtracts) - for future implementation
 * Make it work with Wikidata - tracked in https://phabricator.wikimedia.org/T69434
