Needle in a 930M Member Haystack: People Search AI @LinkedIn

Thursday Jun 15 / 11:50AM EDT, Dumbo / Navy Yard

Abstract

LinkedIn's search functionality is one of its oldest capabilities, allowing members to search for people they know, or to discover new connections. With 900 million members on the platform, LinkedIn faces the challenging task for every search you make: who are the most relevant people to show you?

Unlike other recommendation systems, machine learning systems contain one key component not found elsewhere: the query. User intent is textually explicit through the query, and search results must conform accordingly.

In this presentation, we'll explore how LinkedIn's People Search system uses ML to surface the right person that you're looking for, including but not limited to:
1. Retrieval: determining the profiles relevant to your search intent
2. Ranking: selecting the most relevant profiles to show you

Expertise in ML is not a pre-requisite to enjoy this presentation, and while some background is helpful, all are encouraged to attend.
