Twitter open sources Storm-Hadoop hybrid called Summingbird

Twitter open sources Storm-Hadoop hybrid called Summingbird | Bits 'n Pieces on Big Data R&D | Scoop.it
Twitter has open sourced a “streaming MapReduce” system called Summingbird that makes Hadoop and Storm play nicer together so applications that require both batch and stream processing can do their jobs with as little complexity as possible.

webDEVILopers's curator insight, September 4, 2013 5:56 AM

In the case of Twitter, Hadoop handles batch processing, Storm handles stream processing, and the hybrid system is called Summingbird. It’s not a tool for every job, but it sounds pretty handy for those it’s designed to address. Hybrid systems like this are actually becoming more common as companies realize they can’t survive in a real-time world with Hadoop alone.

Crowdsourcing and Human Computation

Crowdsourcing and Human Computation | Bits 'n Pieces on Big Data R&D | Scoop.it

"Crowdsourcing and human computation are emerging fields that sit squarely at the intersection of economics and computer science. They examine how people can be used to solve complex tasks that are currently beyond the capabilities of artificial intelligence algorithms. Online marketplaces like Mechanical Turk provide an infrastructure that allows micropayments to be given to people in return for completing human intelligence tasks. This opens up previously unthinkable possibilities like people being used as function calls in software. We will investigate how crowdsourcing can be used for computer science applications like machine learning, next-generation interfaces, and data mining. Beyond these computer science aspects, we will also delve into topics like prediction markets, how businesses can capitalize on collective intelligence, and the fundamental principles that underly democracy and other group decision-making processes."

Twitter Data Analytics (Book & Code Examples)

Twitter Data Analytics (Book & Code Examples) | Bits 'n Pieces on Big Data R&D | Scoop.it

Social media has become a major platform for information sharing. Due to its openness in sharing data, Twitter is a prime example of social media in which researchers can verify their hypotheses, and practitioners can mine interesting patterns and build realworld applications. This book takes a reader through the process of harnessing Twitter data to find answers to intriguing questions. We begin with an introduction to the process of collecting data through Twitter's APIs and proceed to discuss strategies for curating large datasets. We then guide the reader through the process of visualizing Twitter data with realworld examples, present challenges and complexities of building visual analytic tools, and provide strategies to address these issues. We show by example how some powerful measures can be computed using various Twitter data sources. This book is designed to provide researchers, practitioners, project managers, and graduate students new to the field with an entry point to jump start their endeavors. It also serves as a convenient reference for readers seasoned in Twitter data analysis.
