Optimized Crowdsourcing Systems for Advanced Structured Query Language Operators

S. Y. Shelar | A. B. Rajmane ^[2]

Abstract: Query optimization plays an important role in crowdsourcing system. We study the optimized crowdsourcing system which is SQL opeartors based crowdsourceing system, in which user submits the query. Crowdsourcing system compiles query and creates the evaluation plans, then excutes selected plan on crowdsourcing platform. A submitted query has many execution plans but selected best query plan gives siginificant effect on overall performance of crowdsource system. For this purpose, we present OptimizedCrowd system in which query optimization is based on latency. In the developed system for query optimization purpose, we use select and join queries.
