CAREER: Real-Time Crowd-Oriented Search and Computation Systems

National Science Foundation Award Number IIS 1149383
CAREER: Real-Time Crowd-Oriented Search and Computation Systems
PI: James Caverlee
Duration (expected): February 2012 - January 2018

Project Overview

This project is focused on highly-dynamic, ad-hoc crowd formation in emerging real-time socio-computational systems. While long-lived communities have been one of the key organizing principles of Web-based systems, these crowds are dynamically formed and potentially short-lived, often with only implicit signals of their formation and evolution. The goal of this research project is to develop the framework, algorithms, and systems for lightweight crowd-oriented search and computation so that stakeholders can distill high-quality information from bursty social systems and actively engage with the crowds generating this information.

Distilling high-quality information from bursty social systems and actively engaging with the crowds generating this information will result in improved real-time decision-making, impacting a wide range of stakeholders from areas such as epidemiology, law enforcement, government, finance, politics, among many others.
