Thank you for any advice!

Answer 1

Not really sure of what you're looking for. Perhaps something like Lucene?

Answer 2

Apache Mahout is an OpenSource Machile Learning library, that can be used with or without MapReduce (Apache Hadoop).

It provides the folloeing algorithms implementation in Java:

• Collaborative Filtering
• User and Item based recommenders
• K-Means, Fuzzy K-Means clustering
• Mean Shift clustering
• Dirichlet process clustering
• Latent Dirichlet Allocation
• Singular value decomposition
• Parallel Frequent Pattern mining
• Complementary Naive Bayes classifier
• Random forest decision tree based classifier

Answer 3

RapidMiner is free and open source and runs on windows, mac, linux, and is a nice graphical workflow based program. It runs all Weka code, and integrates with R.

Answer 4

Weka and Rapidminer aren't that strong on clustering. They mostly do classification and similar predictions, but very little clustering. Have a look at ELKI, which is like WEKA a university project, but has tons of clustering and outlier detection methods.
