Huddler

publication: Huddler: Convening Stable and Familiar Crowd Teams Despite Unpredictable Availability, CSCW'17
Niloufar Salehi, Andrew McCabe, Melissa Valentine, Michael S. Bernstein

Distributed, parallel crowd workers can accomplish simple tasks through workflows. However, as shown in the process knowledge spectrum below, teams of collaborating crowd workers are necessary for complex goals. Unfortunately, a fundamental condition for effective teams — familiarity with other members — stands in contrast to crowd work’s flexible, on-demand nature.

We enable effective crowd teams with Huddler, a system for workers to assemble familiar teams even under unpredictable availability and strict time constraints. Huddler utilizes a dynamic programming algorithm to optimize for highly familiar teammates when individual availability is unknown. We first present a field experiment that demonstrates the value of familiarity for crowd teams: familiar crowd teams doubled the performance of ad-hoc (unfamiliar) teams on a collaborative task. We then report a two-week field deployment wherein Huddler enabled crowd workers to convene highly familiar teams in 18 minutes on average. This research advances the goal of supporting long-term, team-based collaborations without sacrificing the flexibility of crowd work.


Communicating Context to the Crowd

publication: Communicating Context to the Crowd for Complex Writing Tasks, CSCW'17
Best Paper Honorable Mention
Niloufar Salehi, Jaime Teevan, Shamsi Iqbal, Ece Kamar

Crowd work is typically limited to simple, context-free tasks because they are easy to describe and understand. In contrast, complex tasks require communication between the requester and workers to achieve mutual understanding, which can be more work than it is worth. We explore the notion of communication using structured microtasks in the domain of writing. Using an iterative design process we designed the following 5 mechanisms for communicating context:

Our studies compare these mechanisms with respect to the costs to the requester in providing information and the value of that information to workers while performing the task. We find that different mechanisms are effective at different stages of writing. For early drafts, asking the requester to state the biggest problem in the current write-up is valuable and low cost, while later it is more useful for the worker if the requester highlights the text that needs to be improved. These findings can be used to enable richer, more interactive crowd work than what currently seems possible. We incorporate the findings in a workflow for crowdsourcing written content using appropriately timed mechanisms for communicating with the crowd.

Best Paper Honorable Mention

Dynamo is a platform to support the Mechanical Turk community in forming publics around issues and then mobilizing. We are researching new approaches, systems, and labor mechanisms for collective action online.

"Despite their variety, Turkers have something in common—a lack of power. They operate in a realm largely untouched by legislation, unions, and guilds. As a result, the inexperienced can find themselves earning well below minimum wage, or abused by underhanded employers. But a project out of Stanford University [and UC San Diego] is hoping to grant Turkers agency—and might begin to revolutionize the industry. Dynamo is a platform that gives Turkers a collective voice and, consequently, the chance to drive change." -The Daily Beast

Campaigns

1. Have you signed the guidelines for ethical research on MTurk?

Plenty of academic research passes through AMT or is about Turkers, but ethics boards (IRBs) who review and approve research protocols often don't know how workers want to be treated. Turkers have collectively authored these guidelines to help educate researchers and let Turkers hold them accountable to a higher standard.
Email us at info@wearedynamo.org to add your support.


2. Letter writing campaign to Jeff Bezos: I am a human being not an algorithm
All around the world, people are writing letters about themselves to a distant, all-powerful figure who can make their dreams come true. But this year, many of those letters will be addressed to Amazon boss Jeff Bezos rather than Father Christmas. - The Guardian
The goals of this campaign are to publicly state that:
  • Turkers are human beings, not algorithms, and should be marketed accordingly.
  • Turkers should not be sold as cheap labour, but instead skilled, flexible labour which needs to be respected.
  • Turkers need to have a method of representing themselves to Requesters and the world via Amazon.

The Many Faces of Facebook

publication: The Many Faces of Facebook: Experiencing Social Media as Performance, Exhibition, and​ Personal Archive, CHI'13
Best Paper
Xuan Zhao, Niloufar Salehi, Sasha Naranjit, Sara Alwaalan, Stephen Voida, Dan Cosley

How does the relationship between users and their personal collection of social media data shift over time as this “digital trace” is formed? We explored these relationships, tensions, and management strategies involved. User culture of social networks has long been considered as “right here, right now”; However, we believe Facebook Timeline -explicitly supporting access to past data- has created a unique opportunity to rethink the nature of social media, the information it affords, and the user culture around it. We conducted a user study and discussed models and design ideas to address what we found.

Our study shows that people experience the Facebook platform as consisting of three different functional regions: a performance region for managing recent data and impression management, an exhibition region for longer term presentation of self-image, and a personal region for archiving meaningful facets of life. Further, users' need for presenting and archiving data in these three regions is mediated by temporality. These findings trigger a discussion of how to design social media that support these dynamic and sometimes conflicting needs.
