I am able to build a LDA model using Mahout 0.9 CVB implementation. I now need to infer a new document using this model. I was wondering if there is any already existing method/implementation to do the same?

Any help will be highly appreciated. Thanks.

There's not yet a command line mahout algorithm for inferring a single new document with existing lda topic model. Fortunately there are some nice but not-so-well documented tools in mahout library.

I found this blog post that seems to have a working Java example. Inferring should also be quite straight forward to implement with CVB0DocInferenceMapper.
