Human-powered Sorts and Joins
This paper describes how crowds are integrated into a declarative workflow engine called Qurk to reduce the burden on workflow designers. The authors focus on how to use humans to compare items for two of the most common operations in DBMSs: sorting and joining data. Basic query interface and the user interface of the tasks posted to Amazon’s Mechanical Turk were described. They also propose a ...
متن کاملHuman-powered Sorts and Joins
Crowdsourcing markets like Amazon’s Mechanical Turk (MTurk) make it possible to task people with small jobs, such as labeling images or looking up phone numbers, via a programmatic interface. MTurk tasks for processing datasets with humans are currently designed with significant reimplementation of common workflows and ad-hoc selection of parameters such as price to pay per task. We describe ho...

متن کاملCritique of Human-powered Sorts & Joins
Marcus et al. (2011) describe using Amazon’s Mechanical Turk (MTurk) systems utilizing crowds for database sorts and joins. Crowdsourcing activities for these types of queries are typical costly in order to ensure accuracy and reliability. The authors present an interface for optimizing these functions in order to determine cost-effectiveness of various methods (simple join, naïve batching, and...
متن کاملWrite-limited sorts and joins for persistent memory
To mitigate the impact of the widening gap between the memory needs of CPUs and what standard memory technology can deliver, system architects have introduced a new class of memory technology termed persistent memory. Persistent memory is byteaddressable, but exhibits asymmetric I/O: writes are typically one order of magnitude more expensive than reads. Byte addressability combined with I/O asy...
