Research Guide
What is Mobile Crowdsensing and Crowdsourcing?
Mobile Crowdsensing and Crowdsourcing is the use of mobile devices and online crowdsourcing platforms like Amazon's Mechanical Turk to collect data, perform participatory sensing, and conduct research while addressing challenges in data quality, incentive mechanisms, and truth discovery.
The field encompasses 21,085 works focused on crowdsourcing platforms for research and data collection. Key areas include data quality assessment, incentive mechanisms, mobile sensing, truth discovery, and applications in behavioral research and participatory sensing. Studies highlight platforms such as Amazon's Mechanical Turk and alternatives like Prolific.ac for experimental subject recruitment.
Topic Hierarchy
Research Sub-Topics
Amazon Mechanical Turk for Research
Researchers evaluate Mechanical Turk (MTurk) as a platform for scalable behavioral experiments, assessing participant demographics, response quality, and replicability compared to lab studies. Studies develop best practices for task design and validation.
Crowdsourcing Data Quality Assessment
This sub-topic develops metrics, algorithms, and gold standard methods to detect bots, careless responses, and biases in crowdsourced datasets. Research focuses on statistical models for worker reliability and aggregation.
Incentive Mechanisms in Crowdsourcing
Studies design payment schemes, gamification, and reputation systems to optimize worker participation, effort, and truthfulness in online labor markets. Includes economic modeling of worker behavior under varying incentives.
Mobile Crowdsensing Applications
Researchers deploy smartphone-based sensing for urban monitoring, environmental data collection, and participatory mapping via crowdsourced mobile networks. Focuses on privacy-preserving aggregation and real-world deployment.
Truth Discovery in Crowdsourcing
This area develops probabilistic models and algorithms to aggregate conflicting crowd labels or judgments into reliable consensus truths. Applications span entity resolution, sentiment analysis, and multi-source data fusion.
Why It Matters
Mobile Crowdsensing and Crowdsourcing enables low-cost, scalable data collection for experimental research, as demonstrated by Berinsky et al. (2012) who evaluated Amazon's Mechanical Turk for subject recruitment, showing its internal and external validity comparable to traditional methods with 4008 citations. Paolacci et al. (2010) confirmed MTurk's data quality through demographic analysis and experimental results, facilitating behavioral studies with 3752 citations. These platforms support participatory sensing and truth discovery in mobile contexts, with Meade and Craig (2012) providing methods to detect careless responses in survey data, improving reliability across 3295 cited works. Palan and Schitter (2017) introduced Prolific.ac as an alternative subject pool, expanding access for online experiments with 3089 citations.
Reading Guide
Where to Start
"Evaluating Online Labor Markets for Experimental Research: Amazon.com's Mechanical Turk" by Berinsky et al. (2012), as it provides a foundational assessment of MTurk's validity for research recruitment, central to understanding crowdsourcing platforms.
Key Papers Explained
Berinsky et al. (2012) in "Evaluating Online Labor Markets for Experimental Research: Amazon.com's Mechanical Turk" establishes MTurk's experimental validity, which Paolacci et al. (2010) in "Running experiments on Amazon Mechanical Turk" builds upon by validating data quality and demographics. Meade and Craig (2012) in "Identifying careless responses in survey data" extends this by offering detection methods for MTurk data issues. Palan and Schitter (2017) in "Prolific.ac—A subject pool for online experiments" connects as an alternative, addressing MTurk limitations. Gubbi et al. (2013) in "Internet of Things (IoT): A vision, architectural elements, and future directions" provides IoT context for mobile sensing integration.

Frequently Asked Questions
What is Amazon's Mechanical Turk used for in research?
Amazon's Mechanical Turk serves as a platform for recruiting subjects in experimental research, offering low-cost and easy-to-field experiments. Berinsky et al. (2012) assessed its internal and external validity, finding it suitable for political analysis studies. Paolacci et al. (2010) validated data quality through demographic data and attention checks.
How is data quality ensured in crowdsourcing surveys?
Data quality in crowdsourcing surveys is maintained by identifying careless responses using techniques like consistency checks and attention questions. Meade and Craig (2012) outlined methods for detecting such responses in anonymous Internet surveys, particularly under obligatory participation conditions. These approaches enhance reliability in behavioral research.
What role does mobile sensing play in crowdsourcing?
Mobile sensing leverages devices for participatory data collection in crowdsourcing, integrated with platforms like Mechanical Turk. The field description notes its focus on mobile sensing alongside incentive mechanisms and truth discovery. Gubbi et al.
