What Can Machine Learning & Crowdsourcing Do for You? Exploring New Tools for Scalable Data Processing
1 like208 views
The document discusses the intersection of machine learning, crowdsourcing, and human computation, highlighting how these technologies automate tasks and improve data collection efficiency. It emphasizes the value of crowdsourcing for creating labeled data essential for effective machine learning applications and mentions platforms like Amazon Mechanical Turk that facilitate this process. Ethical considerations surrounding these technologies and the implications for worker conditions are also addressed.

- 18. • Marketplace for paid crowd work (“micro-tasks”) – Created in 2005 (remains in “beta” today) • On-demand, scalable, 24/7 global workforce • API lets human labor be integrated into software – “You’ve heard of software-as-a-service. Now this is human-as-a-service.” Amazon Mechanical Turk (MTurk)

Collecting Data from Crowds 2008: MTurk sparks “gold rush” for ML training data • Information Retrieval: Alonso et al., SIGIR Forum • Human-Computer Interaction: Kittur et al., CHI • Computer Vision: Sorokin & Forsythe, CVPR • NLP: Snow et al, EMNLP – Annotating human language – 22,000 labels for only US $26 – Crowd’s consensus labels can replace traditional expert labels

ACM Queue, May 2006 22 “Software developers with innovative ideas for businesses and technologies are constrained by the limits of artificial intelligence… If software developers could programmatically access and incorporate human intelligence into their applications, a whole new class of innovative businesses and applications would be possible. This is the goal of Amazon Mechanical Turk… people are freer to innovate because they can now imbue software with real human intelligence.”

What about ethics? • Silberman, Irani, and Ross (2010) – “How should we… conceptualize the role of these people who we ask to power our computing?” • Irani and Silberman (2013) – “…by hiding workers behind web forms and APIs… employers see themselves as builders of innovative technologies, rather than… unconcerned with working conditions… redirecting focus to the innovation of human computation as a field of technological achievement.” • Fort, Adda, and Cohen (2011) – “…opportunities for our community to deliberately value ethics above cost savings.” 27
