The implementation is described in this [paper](https://ufal.mff.cuni.cz/pbml/102/art-baltescu-blunsom.pdf). The original cython extractor is described in [Adam Lopez](http://www.cs.jhu.edu/~alopez/)'s PhD [thesis](http://www.cs.jhu.edu/~alopez/papers/adam.lopez.dissertation.pdf). The grammar extraction takes place in two steps: (a) precomputing a number of data structures and (b) actually extracting the grammars. All the flags below have the same meaning as in the cython implementation. To compile the data structures you need to run: - cdec/extractor/compile -a <alignment> -b <parallel_corpus> -c <compile_config_file> -o <compile_directory> + cdec/extractor/sacompile -a <alignment> -b <parallel_corpus> -c <compile_config_file> -o <compile_directory> To extract the grammars you need to run: diff --git a/extractor/sacompile.cc b/extractor/sacompile.cc index 3ee668ce..d80ab64d 100644 --- a/extractor/sacompile.cc +++ b/extractor/sacompile.cc @@ -114,6 +114,7 @@ int main(int argc, char** argv) { stop_write = Clock::now(); write_duration += GetDuration(start_write, stop_write); + stop_time = Clock::now(); cerr << "Constructing suffix array took " << GetDuration(start_time, stop_time) << " seconds" << endl; |
