Dimension Independent Similarity Computation (DISCO)
MapReduce is a programming model for processing large data sets, typically used to do distributed computing on clusters of commodity computers. With large amount of processing power at hand, it’s very tempting to solve problems by brute force. However, we often combine clever sampling techniques with the power of MapReduce to extend its utility. Consider the problem of finding all pairs of similar
Efficient Parallel Set-Similarity Joins Using MapReduce
Department of Computer Science University of California, Irvine Abstract In this paper we study how to efficiently perform set-similarity joins in parallel using the popular MapReduce framework. We propose a 3-stage approach for end-to-end set-similarity joins. We take as input a set of records and output a set of joined records based on a set-similarity condition. We efficiently partition the dat
