A segmental CRF (SCRF) is a model that defines a probability distribution on a set of paths between two vertices. An edge in a path is often considered as a segment, hence the name.
You can read more about the experiments done with this toolkit in "A comparison of training approaches for discriminative segmental models."
The scrf package depends on ebt and fst. You need to download all three of them.
You need GCC 4.8.2 or above to compile.
Download the package, and follow the steps.
