It also provides some very impressive results of what they are capable of. This is a great post, and if you are interested in natural language, machine learning or neural networks you should definitely read it.

The Structure of Apache Lucene
The inestimably noble Apache Software Foundation produces many of the blockbuster products (Ant, CouchDB, Hadoop, JMeter, Maven, OpenOffice, Subversion, etc.) that help build our digital universe.
