In R, I can get a matrix representation of the lsaspace using as.textmatrix(lsaspace). Is there a way to get the same using weka's lsa package?
In R:
lsaspace = lsa(matrix)
m2 = as.textmatrix(lsaspace)
Looking to do the same using weka/lsa.
Thanks

Hi Sudhakar,
I don't know how it works in R or exactly what that will give you, but
if you use LSA's toString() function it will print out information on
the singular values and the left and right singular vectors.

Thank you for the response Amri.
I can compute the resulting matrix, if I can get access to the singular values and the left/right singular vectors. Essentially looking for methods that give me access to the private vars m_s, m_v and m_u.

I updated it to include getU(), getV(), and getSigma() functions to
return those matrices. It hasn't been added to the official list yet
but I think you can install it now using the command line version of
the package manager (I've never done it before but this page:
http://weka.wikispaces.com/How+do+I+use+the+package+manager%3F talks
about it). The URL for the package is below.

The package has been updated on the official list now also.
