Shop The Look: Building a Large Scale Visual Shopping System at Pinterest

As online content becomes ever more visual, the demand for searching by visual queries grows correspondingly stronger. Shop The Look is an online shopping discovery service at Pinterest, leveraging visual search to enable users to find and buy products within an image. In this work, we provide a holistic view of how we built Shop The Look, a shopping oriented visual search system, along with lessons learned from addressing shopping needs. We discuss topics including core technology across object detection and visual embeddings, serving infrastructure for realtime inference, and data labeling methodology for training/evaluation data collection and human evaluation. The user-facing impacts of our system design choices are measured through offline evaluations, human relevance judgements, and online A/B experiments. The collective improvements amount to cumulative relative gains of over 160% in end-to-end human relevance judgements and over 80% in engagement. Shop The Look is deployed in production at Pinterest.Comment: 10 pages, 7 figures, Accepted to KDD'2

Examining Pinterest as a Curriculum Resource for Negative Integers: An Initial Investigation

This paper reports an investigation of mathematical resources available on the social media site Pinterest. Pinterest is an online bulletin board where users create visual bookmarks called pins in order to share digital content (e.g., webpages, images, videos). Although recent surveys have shown that Pinterest is a popular reference for teachers, understanding of the mathematical resources available on the site is lacking. To take initial steps in investigating the curriculum resources provided by Pinterest, we used keyword searches to gather a database of pins related to the topic of negative integers. A content analysis was conducted on the pins with a focus on several characteristics including mathematical operations, mathematical models, use of real-world context, and whether mathematical errors were present in source material. Results show a dominance of addition and subtraction over other operations, use of mathematical models in half of pins, infrequent use of real-world context, and mathematical errors in roughly one-third of pins. We provide a breakdown of these results and discuss implications of the findings for mathematics teacher education and professional development

Pinning it down: An evaluation of Pinterest’s function in the British academic library

University libraries have found a useful resource for themselves in many social media platforms. At Leeds Beckett University Library (formerly Leeds Metropolitan University), Twitter has proved a popular way to connect with students, other libraries and universities. Our Twitter following has exceeded 3,800, and our library Facebook had over 1,100 followers by May 2014. While we continue to develop these two sites, however, we acknowledge that we are not part of a stable environment. Social media is faddish; the favoured platforms change frequently. Facebook has largely taken custom away from Myspace, while Myspace used to tussle for users with Bebo, and Google Plus has taken their share of professional networks away from other platforms. With this in mind, any organisation using social media has to think about whether they should use – and if so, how to use – emerging virtual social networks

Reflective case study. My ‘Pinteresting’ project: Using Pinterest to increase student engagement, promote inclusivity and develop employability skills

This article will give an overview of my Pinterest project, outlining a rationale for using social bookmarking sites and specifically Pinterest. It will then outline the aims of my practice, linking to research and implementation by other educators, before describing the boards I have set up with visuals and finally evaluating its impact and looking forward to future possibilities for research
