Configuring Mahout Clustering Jobs, Frank Scholten, JTeam, Eurocon 2011 from Lucene Revolution on Vimeo.

For more than a decade internet search engines have helped users find documents they are looking for. However, what if users aren't looking for anything specific but want a summary of a large document collection and want to be surprised? One solution to this problem is document clustering. Clustering algorithms group documents that have similar content. Real-life examples of clustering are clustered search results of Google news, or tag clouds which group documents under a shared label. Apache Mahout is a framework for scalable machine learning on top of Apache Hadoop and can be used for large scale document clustering. This talk introduces clustering in general and shows you step-by-step how to configure Mahout clustering jobs to create a tag cloud from a document collection. This talk is suitable for people who have some experience with Hadoop and perhaps Mahout. Knowledge of clustering is not required.

Topics include

  • Clustering introduction
  • Clustering in Mahout
  • Text pre-processing & analysis
  • Tag cloud demo
  • Tips & tricks
