Hi!

I'm trying to run ZGen on my OSX. ./configure works quite well, but than when I run make, I get this:
[ 3%] Linking CXX executable bin/unittest ld: library not found for -lboost_thread clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: *** [bin/unittest] Error 1 make[1]: *** [CMakeFiles/unittest.dir/all] Error 2 make: *** [all] Error 2

Any ideas how I can fix it? I have Boost installed of course.

If no ngram LM is used, the code fails in decoder.cc file in below lines:
if(model->ngram != NULL)
ctx->lattice[0].ngstate = (model->ngram)->BeginSentenceState();

Here ngram is not NULL and it goes inside the control structure and throws a Segmentation fault

Generated build files are checked in. They are not needed. build/ directory can be empty

Hello all,

We would like to use ZGen to linearise dependency trees, that is, our input is an unordered tree, for example:

<NODE lem="love" si="root">
  <NODE lem="Mary" si="nsubj"/>
  <NODE lem="beer" si="obj"/>
</NODE>

And the output is a sequence of tokens in order, e.g. "Mary love beer".

I have read the documentation, but I can't find out how I would train such a model.

Some specific questions:

1. What does -1 and 1 mean in the constraints format ? Is -1 = head and 1 = dependent?
2. Could the constraints be extracted from a treebank ?

If there is some other documentation and I've missed it, apologies!

I just try the code, but I get the error as:

What is the problem?

When compling with gcc 5.2 and boost 1.58.0, I get the following error:

Any idea where it comes from?

Hello,

I'm trying to run ZGen with this as my input.in file:

__Ms._Haag__ _ 1 N
plays _ -1 N
__Elianti__ NP -1 _
. . 1 N

Using this command:
./bin/ZGen_SR test \
--type none \
--model /path/to/your/model \
--input /path/to/your/input_file \
--posdict /path/to/your/postag_dict

Using the model linked in the documentation.

And my output is this:
2017-01-06 23:11:21 [warning] parseopt: postag dict is specified.

Do you have any ideas how to fix it? Am I doing something wrong?
