Design and Implementation of Parallel Term Contribution Algorithm Based on Mapreduce Model

MapReduce is a software framework introduced by Google in 2004 to support distributed computing on large datasets on clusters of computers[1]. The term contribution (TC) algorithm is a relatively new algorithm in text mining to select features for clustering. In this paper, we design and implement a parallel term contribution (PTC) algorithm based on MapReduce model. By experiment, we come to the conclusion that the performance of TC is greatly enhanced using MapReduce framework.
