Phase 2a) Combining platform article lists

← Phase 2) | Phase 2b) →

After the lists have been extracted from the NewsWhip Insights database, a single sample of articles will be extracted, following a protocol of alternating between the two lists and eliminating duplicates. A study administrator will be responsible for combining the two lists into one, following the procedure below.

The detailed sampling steps are the following:

  1. Each of the NewsWhip Insights lists are ordered in descending order of popularity (defined as number of Facebook shares or Twitter retweets).
  2. The first list from which an article is selected is chosen randomly between the two lists (Facebook or Twitter) by coin flip.
  3. The most popular article in the currently selected social media platform list, defined as the one receiving the largest number of shares in its media platform within a month of publication, among the remaining ones in that platform list is selected into the sample.
  4. The newly added article is removed from both platforms’ lists of potential review articles.
  5. Steps 3 to 4 get repeated, alternating the social media platform at each iteration, until the sample list has enough articles to complete the selection and review phases.
