Structured Data Across Wikimedia/Image Suggestions/it

Questa pagina descrive il lavoro in corso per progettare e costruire funzioni di suggerimento di immagini per utenti esperti, che il team di Structured Data Across Wikimedia sta attualmente sviluppando.

Questo lavoro si baserà sul lavoro già svolto per il task "aggiungi un'immagine". Tuttavia, la sua attenzione sarà maggiormente volta al miglioramento dei processi per gli utenti esperti. In particolare, ci rivolgeremo agli utenti che hanno curato o messo nei propri osservati speciali una particolare voce o un gruppo di voci, poiché è probabile che siano esperti nell'argomento e che abbiano interesse a vedere quella voce o quelle voci migliorare.

Dopo aver raccolto un feedback iniziale da varie comunità, il progetto è adesso in una prima fase di test, che prevedrà di sperimentare delle notifiche per annunciare agli utenti potenziali immagini utili per le voci di Wikipedia.

Contesto
L'interfaccia di suggerimento delle immagini è una componente fondamentale del progetto SDAW, che intende sviluppare un sistema di dati strutturati attraverso tutti i progetti Wikimedia.

Le immagini sono fondamentali per illustrare i concetti e aiutare le persone a capire gli argomenti. Considerando che Wikimedia Commons contiene oltre 65 milioni di immagini, crediamo che sia possibile rendere le versioni di Wikipedia maggiormente più illustrate con le immagini di Commons. Crediamo che i dati strutturati possano aprire una forma di scambio duratura tra Commons e Wikipedia per arricchire contenuti. Questo ci aiuterà, a sua volta, a far crescere e diversificare gli utenti, migliorare il contenuto per i lettori e ridurre le lacune nei contenuti.

Nonostante ciò, in molte Wikipedia più della metà delle voci non ha immagini. Questo è dovuto primariamente alla complessità dell'attuale processo di aggiunta di immagini e di connessione fra contenuto e immagini. Noi vogliamo rendere questo processo più semplice.

Il nostro punto di partenza
Come abbiamo già detto, questo strumento si baserà sul lavoro già svolto per il task "aggiungi un'immagine". La API di suggerimento delle immagini, costruita dal team di Platform Engineering, combina i risultati dell'algoritmo di suggerimento delle immagini e di MediaSearch, per fornire suggerimenti di potenziali combinazioni di immagini e voci non illustrate, seguendo il seguente approccio:
 * 1) Controlla l'elemento Wikidata di una voce.
 * 2) If it has, suggest that image.
 * 3) If it has, suggest an image from the category.
 * 4) Look at the articles about the same topic in other language Wikipedias. Suggest a lead image from those articles.
 * 5) Search MediaSearch on Commons for the title of the article, which combines traditional text-based search with structured data from Commons and Wikidata. If an image ranks high enough in the results, suggest that image.

In initial tests, the combined algorithms can suggest images for up to 40% of all unillustrated articles on a given Wikipedia. We are currently doing further testing of the accuracy of the matches. Also, the Android and Growth teams are testing ideas that use the Image Suggestion API to allow newcomers to add images to articles via the suggested tasks interface.

We are also experimenting with adding the results from the Image Suggestions Algorithm directly to MediaSearch. We hope that will simplify the process technically and improve MediaSearch results. See on Phabricator for more information.

What we want to do
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.

Tentative workflow
The following is the current tentative workflow we defined for this stage of testing. Wherever appropriate, there is a link to the related task on Phabricator.
 * 1) Notifications are sent weekly to all users who have at least 500 edits at a predefined day and time (e.g. every Monday at 08:00 AM UTC), all across the globe → see  on Phabricator
 * 2) Notification includes a link to user’s preferences to allow users to opt out of the notifications → about opting-out, see  on Phabricator
 * 3) * “Image Suggestions” options would be added to bottom of the list of users’ opt-in/opt-out notifications
 * 4) Suggestions are selected randomly from the list of matched recent images to unillustrated articles, using the algorithms explained above
 * 5) Users are selected randomly from a group of users that:
 * 6) * have at least 500 edits on the project
 * 7) * did not opt-out of the notification
 * 8) * have received up to 2 image notifications in a given week
 * 9) The tool will check the user’s watchlist for articles edited in the last 30 days
 * 10) * If the user has already received a notification for the article ID, the tool skips to the next article
 * 11) * Otherwise, it matches one suggestion and sends the notification
 * 12) If image matches remain, then the tool checks for other articles on users watchlist
 * 13) The notification process will be generated weekly, until image matches are exhausted or applicable users are exhausted
 * 14) * Notifications for a particular article-image match notification will only be shown once to a particular user
 * 15) * The same match can be sent to multiple users to review (except in the case the image has been inserted)

User experience
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

Ideas for the future
The following bullet list lists all the ideas that are out of scope of the current test stage, but might be worked upon in the future:
 * Suggestions to users who have uploaded images on Commons that match articles
 * Suggestions given in other ways besides via notifications (e.g. suggestions in the image search dialogue in VisualEditor)
 * Illustrated articles
 * Section level image suggestions
 * A tool to help users add images to the article
 * A landing page that lets users review multiple suggestions at once
 * Limiting notifications only to users who have a history of adding images to articles in the last 30 days

Metrics and analytics
We are planning on measuring the following metrics, to analyse 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 article within a month of receiving the notification
 * 5) Number of suggested images not reverted from their matched article (low revert rate = good quality of suggested matches)

What we don’t want to do

 * Create a new tool that will go unused due to lack of incentive for use
 * Annoy users with too many notifications
 * Encourage edits that will overwhelmingly be reverted
 * Encourage edits that go against existing policies and/or practises (NPOV, original research...)
 * Encourage edits that introduce additional bias in the article

Feedback
Project feedback is and will always be welcome. We are especially interested in your ideas, and we are looking forward to hearing from you on the talk page about the following open questions:
 * 1) What is your opinion about the approaches outlined above?
 * 2) Should we be helping editors with image placement location?
 * 3) How can we help users make sure they are following the conventions of a particular wiki when choosing and placing an image?
 * 4) How can we help users add appropriate captions?
 * 5) How can we help users add appropriate alt-text?

What is the Image suggestion tool about?
The image suggestion tool is a key component of the Structured Data Across Wikimedia project, and it aims to make it easier for users to find potential images and media for currently unillustrated articles.

Does the Image suggestion tool somehow intersect with the “Add an image” tool from the Growth Team?
Technically yes. The two tools share the same algorithm, but they also serve different purposes:
 * the “Add an image” tool is intended for newcomers and less experienced users, who have little to no experience with adding images;
 * the Image suggestion tool is intended for more established users, who already have experience with adding images and other media to articles (i.e. users with more than 500 edits).

What is the relation between the Image suggestion tool and Wikidata/Structured Data on Commons?
This tool will leverage the data coming from Wikidata and Structured Data on Commons to find potential media to add on unillustrated Wikipedia articles.

More specifically, the tool will look at the relative Wikidata item, and will check if it has an image (through Wikidata property P18) or an associated Commons category (through Wikidata property P373). If in both cases no potential images are found, it will look at other Wikipedia articles in other languages to see if there is a lead image to be found. Finally, the tool will search MediaSearch on Commons for the title of the article, and if an image ranks high enough in the results, the tool will choose that image.
