Endorsements are a one-click system to recognize someone for their skills and expertise on LinkedIn, the largest professional online social network. This is one of the latest “data features” in LinkedIn’s portfolio, and the endorsement ecosystem generates a large graph of reputation signals and viral user activity.
In this talk, we’ll examine the practical aspects of building a data feature like Endorsements. We’ll talk about marrying product design and data, deep diving into several of the lessons we’ve learned along the way - all using skills & endorsements as an empirical case study. We’ll include technical detail on our approaches and how we combine crowdsourcing, machine learning, and large scale distributed systems to recommend topics to users.
