edu.umd.cloud9.example.cooccur.ComputeCooccurrenceMatrixStripes

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

public class ComputeCooccurrenceMatrixStripes
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

Implementation of the "pairs" algorithm for computing co-occurrence matrices from a large text collection. This algorithm is described in Chapter 3 of "Data-Intensive Text Processing with MapReduce" by Lin & Dyer, as well as the following paper:

Jimmy Lin. Scalable Language Processing Algorithms for the Masses: A Case Study in Computing Word Co-occurrence Matrices with MapReduce. Proceedings of the 2008 Conference on Empirical Methods in Natural Language Processing (EMNLP 2008), pages 419-428.
