How Vox Media built a bot for discovering related content

After talking to editors and hearing a need for a tool to find older articles that people may have forgotten about, the Vox Media product team built a bot to solve the problem. The team chose to build a Slack bot, making it easier for editors to use the bot within their existing workflows. An editor sends a direct message to the bot with a specific article URL and a number of desired results, and the bots returns a ranked list of articles that are most similar in content to the provided article.
