Use of OWL and Semantic Web Technologies at Pinterest

Pinterest is a popular Web application that has over 250 million active users. It is a visual discovery engine for finding ideas for recipes, fashion, weddings, home decoration, and much more. In the last year, the company decided to create a knowledge graph that aims to represent the vast amount of content and users on Pinterest, to help both content recommendation and ads targeting. In this talk, we present the engineering of an ontology--the Pinterest Taxonomy--that forms the core of Pinterest's knowledge graph, the Pinterest Taste Graph. We describe modeling choices and enhancements to the cloud-based WebProtégé tool that we used for the creation of the ontology. In two months, eight Pinterest engineers, without prior experience of ontologies, knowledge graphs, and WebProtégé, revamped an existing taxonomy of noisy terms into an OWL ontology, which they then combine with additional structured information and machinery to form the Pinterest Taste Graph. We share our experience and present the key aspects of our work that we believe will be useful for others working in this area.

Lightening talks from the Main Stage along with speaker Q&A sessions

May 4-7, 2020


Knowledge Graphs form an organized and curated set of facts that provide support for models to help understand the world. This conference gathers technology leaders, researchers, academics, vendors — and most importantly, practitioners, who know the discipline. For KGC 2020, attendees can participate from wherever they want in the world, from the comfort of their homes. We will stream the content, provide access to our speakers and support chat and networking as well as give access to all of the content live and on-demand after the event.
