How Social Ties Influence Hurricane Evacuation Behavior

Conference on Computer-Supported Cooperative Work and Social Computing (CSCW)

This work is the first of its kind, examining these phenomena across three major disasters in the United States—Hurricane Harvey, Hurricane Irma, and Hurricane Maria—using aggregated, de-identified data from over 1.5 million Facebook users.

The Effect of Computer-Generated Descriptions on Photo-Sharing Experiences of People with Visual Impairments

Conference on Computer-Supported Cooperative Work and Social Computing (CSCW)

Like sighted people, visually impaired people want to share photographs on social networking services, but find it difficult to identify and select photos from their albums. We aimed to address this problem by incorporating state-of-the-art computer-generated descriptions into Facebook’s photo-sharing feature.

Social media governance: Can companies motivate voluntary rule following behavior among their users

Social Media Governance Workshop

The question of how to effectively enforce rules on social media mirrors the general question of how to enforce laws in society. One model for both governments and private companies is incapacitation—preventing people from taking particular actions.

Neural Compositional Denotational Semantics for Question Answering

Conference on Empirical Methods in Natural Language Processing (EMNLP)

Answering compositional questions requiring multi-step reasoning is challenging. We introduce an end-to-end differentiable model for interpreting questions about a knowledge graph (KG), which is inspired by formal approaches to semantics.

The effects of natural scene statistics on text readability in additive displays

Human Factors and Ergonomics Society

The minimum contrast needed for optimal text readability with additive displays (e.g. AR devices) will depend on the spatial structure of the background and text. Natural scenes and text follow similar spectral patterns. Therefore, natural scenes can mask low contrast text – making it difficult to read. In a set of experiments, we determine the minimum viable contrast for readability on an additive display.

Low-Dose-Rate Cobalt-60 Testing Results for Kaman KD-5100 Differential Inductive Position Measuring Systems

Journal, IEEE Radiation Effects Data Workshop (REDW)

We report 60Co gamma radiation testing of a Kaman KD-5100 position measuring system to a total ionizing dose of 10 kRad(Si) at a rate of 5 mRad(Si)/s.

From Start-ups to Scale-ups: Opportunities and Open Problems for Static and Dynamic Program Analysis

IEEE International Working Conference on Source Code Analysis and Manipulation (SCAM)

This paper describes some of the challenges and opportunities when deploying static and dynamic analysis at scale, drawing on the authors’ experience with the Infer and Sapienz Technologies at Facebook, each of which started life as a research-led start-up that was subsequently deployed at scale, impacting billions of people worldwide.
