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.

A Face Recognition Application for People with Visual Impairments: Understanding Use Beyond the Lab
Conference on Human Factors in Computing Systems (CHI)
We present Accessibility Bot, a research prototype bot on Facebook Messenger, which leverages state-of-the-art computer vision algorithms and the existing set of tagged photos of a user’s friends on Facebook to help people with visually impairments recognize their friends.

Social Structure and Trust in Massive Digital Markets
International Conference on Information Systems (ICIS)
In this paper we measure the extent to which situating transactions in networks can generate trust in online marketplaces with an empirical approach that provides external validity while eliminating many potential confounds.

Social Hash Partitioner: A Scalable Distributed Hypergraph Partitioner
Very Large Data Bases Conference (VLDB)
We design and implement a distributed algorithm for balanced k-way hypergraph partitioning that minimizes fanout, a fundamental hypergraph quantity also known as the communication volume and (k − 1)-cut metric, by optimizing a novel objective called probabilistic fanout. This choice allows a simple local search heuristic to achieve comparable solution quality to the best existing hypergraph partitioners.

Untagging on Social Media: Who Untags, What do they Untag, and Why?
Journal: Computers in Human Behavior
Using de-identified, aggregated behavioral data from Facebook and a survey of 802 people, this paper aims to explore untagging by asking whether untagging occurs similarly to other self-presentation behavior and how people view this strategy.

Is smoke on your mind? Using social media to improve smoke exposure estimates – Atmospheric Chemistry and Physics Discussions (ACPD)
Journal: Atmospheric Chemistry and Physics Discussions
In this work, we explore using daily social media posts from Facebook regarding smoke, haze, and air quality to assess population-level exposure for the summer of 2015 in the western US. We compare this de-identified, aggregated Facebook dataset to several other datasets that are commonly used for estimating exposure, such as satellite observations (MODIS aerosol optical depth and Hazard Mapping System smoke plumes), daily (24 h) average surface particulate matter measurements, and model-simulated (WRF-Chem) surface concentrations.

Cultural Diffusion and Trends in Facebook Photographs
The International AAAI Conference on Web and Social Media (ICWSM)
Online social media is a social vehicle in which people share various moments of their lives with their friends, such as playing sports, cooking dinner or just taking a selfie for fun, via visual means, i.e., photographs. Our study takes a closer look at the popular visual concepts illustrating various cultural lifestyles from aggregated, de-identified photographs.

Connective recovery in social networks after the death of a friend
Nature Human Behavior
Most individuals have few close friends, leading to potential isolation after a friend’s death. Do social networks heal to fill the space left by the loss? We conduct such a study of self-healing and resilience in social networks.
