The S-Space Package is a Natural Language Processing library for
distributional semantics representations. Distributional semantics
representations model the meaning of words, phrases, and sentences as high
dimensional vectors or probability distributions. The library includes common
algorithms such as Latent Semantic Analysis, Random Indexing, and Latent
Dirichlet Allocation. The S-Space package also includes software libraries
for matrices, vectors, graphs, and numerous clustering
algorithms.
