This is a C++ library for making and modifying n-gram language models encoded as weighted finite-state transducers. It uses OpenFst finite-state transducers (FSTs) and FST archives (FARs) as inputs and outputs.
This library is primarily developed by Brian Roark
This library depends on:
- A standards-compliant C++17 compiler (GCC >= 7 or Clang >= 700)
- The most recent version of OpenFst built with the
grmextensions (i.e., built with./configure --enable-grm) and headers
This library uses GNU autotools so one can simply use the standard ./configure; make; make install conventions for compilation and installation.
Alternatively, one can use Bazel to compile the libraries
by running bazel build //:all anywhere in the source tree.
- Binaries will normally be installed in
/usr/local/bin - Libraries will normally be installed in
/usr/local/lib - Headers will normally be installed in
/usr/local/include/ngram
Linking is, by default, dynamic so that theFst and Arc type DSO extensions
can be used correctly if desired.
