If you just want to try out the parser on a pre-trained model, you can install the wheel with pip and download a pre-trained parser model. On a Linux machine with Python 2.7 you can install a pre-built wheel:
sudo pip install http://www.jbox.dk/sling/sling-2.0.0-cp27-none-linux_x86_64.whl
and download the pre-trained model:
wget http://www.jbox.dk/sling/caspar.flow
You can then use the parser in Python:
import sling
parser = sling.Parser("caspar.flow")
text = raw_input("text: ")
doc = parser.parse(text)
print doc.frame.data(pretty=True)
for m in doc.mentions:
print "mention", doc.phrase(m.begin, m.end)
If you want to train a parser or use SLING for C++ development, you need to download the source code and build it.
First, clone the GitHub repository.
git clone https://github.com/google/sling.git
cd sling
SLING uses Bazel as the build system, so you need to install Bazel in order to build the SLING parser.
sudo apt-get install pkg-config zip g++ zlib1g-dev unzip python2.7 python2.7-dev
wget -P /tmp https://github.com/bazelbuild/bazel/releases/download/0.13.0/bazel-0.13.0-installer-linux-x86_64.sh
chmod +x /tmp/bazel-0.13.0-installer-linux-x86_64.sh
sudo /tmp/bazel-0.13.0-installer-linux-x86_64.sh
The parser trainer uses Python v2.7 and PyTorch for training, so they need to be installed.
sudo pip install http://download.pytorch.org/whl/cpu/torch-0.3.1-cp27-cp27mu-linux_x86_64.whl
Operating system: Linux
Languages: C++, Python 2.7, assembler
CPU: Intel x64 or compatible
Build system: Bazel
You can use the buildall.sh
script to build all the source code:
tools/buildall.sh
You then need to link the sling Python module directly to the Python source directory to use it in "developer mode":
sudo ln -s $(realpath python) /usr/lib/python2.7/dist-packages/sling
NOTE:
- In case you are using an older version of GCC (< v5), you may want to comment out this cxxopt in .bazelrc.
- We currently do not support OSX, but you can check out issue #189 for help on building on OSX.
- Similarly, we do not support Windows, but you can check out issue #296 for help on building SLING on Windows Subsystem for Linux (WSL).
