We utilize a variety of methods from mining data on social media to conducting controlled experiments to interviewing users. Our work aims to understand the significance of people’s digital traces and to leverage this information for positive social good.

As part of the AOL Connected Experiences Laboratory, we look at how data from mobile devices, sensors, as well as new cryptographic techniques and protocols can enable a socio-technical infrastructure to provide awareness, trust and meaningful connections between physically co-located individuals, including buildings, offices, and public spaces. Such infrastructure will empower people to make better connections and communication in their local communities, with long term impact on participation and democracy.
The goal of this project is to advance our understanding of the psychological mechanisms behind people's attention, as reflected through their interactions with digital content. In particular, we focus on the context of actions that people take online without any experimental intervention and examine how context affects behavior. We draw on theories from a wide range of fields to address questions that pertain to individual's attention to content, expectations for attention from others and the value in getting that attention. To that end, we harness machine learning methods as well as language and statistical modeling to analyze signals of human attention as they occurs naturally outside of lab settings.

NEWSROOM: A Dataset of 1.3 Million Summaries with Diverse Extractive Strategies
We present NEWSROOM, a summarization dataset of 1.3 million articles and summaries written by authors and editors in newsrooms of 38 major news publications. Extracted from search and social media metadata between 1998 and 2017, these high-quality summaries demonstrate high diversity of summarization styles. In particular, the summaries combine abstractive and extractive strategies, borrowing words and phrases from articles at varying rates. We analyze the extraction strategies used in NEWSROOM summaries against other datasets to quantify the diversity and difficulty of our new data, and train existing methods on the data to evaluate its utility and challenges. The dataset is available online at summari.es

ShareBox: Designing A Physical System to Support Resource Exchange in Local Communities.
ShareBox is a technology probe that facilitates local borrowing and lending of physical items using a chatbot and smart lockbox. We describe the design of ShareBox and evaluate a set of design guidelines, including the physical-virtual nature of the system, anonymity and asynchronous exchange, through three short deployments. Our findings, based on semi-structured interviews with community members, highlight the potential and remaining challenges in our design.

We build on the increasing availability of Virtual Reality (VR) devices and Web technologies to conduct behavioral experiments in VR using crowdsourcing techniques. A new recruiting and validation method allows us to create a panel of eligible experiment participants recruited from Amazon Mechanical Turk. Using this panel, we ran three different crowdsourced VR experiments, each reproducing one of three VR illusions: place illusion, embodiment illusion, and plausibility illusion. Our experience and worker feedback on these experiments show that conducting Web-based VR experiments using crowdsourcing is already feasible, though some challenges---including scale---remain. Such crowdsourced VR experiments on the Web have the potential to finally support replicable VR experiments with diverse populations at a low cost.

A Multi-site Investigation of Community Awareness Through Passive Location Sharing
We aim to understand if and how passive location sharing might be socially beneficial for communities. We conducted a deployment of MoveMeant (see Sun et al. CHI 2017) and 45 interviews with users of the system and community leaders across three different communities. We discuss the issues that communities face and the potential positive and negative repercussions of surfacing passive location information.

A Computational Approach to Perceived Trustworthiness of Airbnb Host Profiles
Building on our previous work (see below by Ma et al. CSCW 2017), we developed a novel computational framework to predict the perceived trustworthiness of host profile texts in the context of online lodging marketplaces. We developed a dataset of 4,180 Airbnb host profiles annotated with perceived trustworthiness, and also provide insights into the linguistic factors that contribute to higher and lower perceived trustworthiness for profiles of different lengths.

Website measures of engagement captured from millions of users, such as in-page scrolling and viewport position, can provide deeper understanding of attention than possible with simpler measures, such as dwell time. Using data from 1.2M news reading sessions, we examine and evaluate three increasingly sophisticated models of sub-document attention computed from viewport time, the time a page component is visible on the user display. Our approach supports refined large-scale measurement of user engagement at a level previously available only from lab-based eye-tracking studies.

MoveMeant: Anonymously Building Community Through Shared Location Histories

“People Are Either Too Fake or Too Real”: Opportunities and Challenges in Tie-Based Anonymity
We interviewed users of two anonymous social applications, Secret and Mimi, both of which allowed people to share information anonymously with friends. Our findings show that although users feel more comfortable sharing information on these “tie-based” anonymous applications, they are still concerned about being identified, and at the same time, engage in sometimes elaborate attempts to uncover the identities of others.
Nir Grinberg, Shankar Kalyanaraman, Lada Adamic, and Mor Naaman. Understanding Feedback Expectation on Facebook. In Proceedings, ACM International Conference on Computer-Supported Cooperative Work. (CSCW 2017), February 2017, Portland, USA
In this study, we quantitatively examined the factors contributing to feedback expectations and find that fulfilling expectations is linked to connectedness, an important ingredient for well-being. By conducting two large surveys on Facebook.com we find that people report higher expectations on posts they evaluated as more important, and to a lesser extent more personal. Expectations varied across people and friendships, most notably by recency of communication, geographical proximity, and the type of relationship (e.g. family, co-worker). The study provides a conceptual framework for thinking about feedback expectations in social media settings and a computational model for utilizing expectations in the design of social systems.

Self-Disclosure and Perceived Trustworthiness of Airbnb Host Profiles
Best Paper Honorable Mention
We conducted the first large-scale mixed-method analysis of Airbnb host profiles, by categorizing the types of information hosts share in their profiles, and assessing how trustworthy their profiles are perceived to be. We found that hosts do not always follow the prompts by Airbnb website, but instead disclose information that reduces the uncertainty of anticipated future interaction. The language of hospitality, i.e., making direct promises to take care of guests, was found to be the most effective in establishing perceived trustworthiness.

TAMIES: A Study and Model of Adoption in P2P Resource Sharing and Indirect Exchange Systems
Peer-to-peer indirect exchange services, such as Peerby and NeighborGoods, do not seem to have been as widely adopted as direct exchange systems, such as Uber and AirBnb. Building upon the results of interviews with 37 residents of New York City, a survey with 195 respondents, previous technology acceptance models, critical mass theory, and prior research on peer economies, we propose a technology acceptance model for indirect exchange systems that includes generalized trust and ease of coordination.

What Happens in happn: The Warranting Power of Location History in Online Dating
We interviewed users of a novel mobile dating application, happn, which shows users the number of times they crossed path with potential matches. We show that users assigned significant meaning to the minimal cues available from location history information. At the same time, users have concerns about security and recognition by known others as a result of sharing personal location history.

Changes in Engagement Before and After Posting to Facebook

The study identified a unique pattern of engagement that accompanies posting on Facebook. Using observational data analysis we show that after posting content, people visit the site more often, are more attentive to content from friends, and even interact more with friends content.
