Requirements

The toolkit requires libsqlite3 development files, header files and static libraries for Python and Cython.

For Ubuntu, these are available as following packages:

• libsqlite3-dev
• python-dev
• cython

The webUI requires the python libraries flask, requests and yaml, and for uWSGI based deployment the uwsgi program and its python plugin. For Ubuntu, these are available as:

• uwsgi
• uwsgi-plugin-python
• python-flask
• python-yaml
• python-requests

You also need a basic build environment (make, C compiler, …):

• build-essential

sudo apt-get install build-essential libsqlite3-dev python-dev cython uwsgi uwsgi-plugin-python python-flask python-yaml python-requests

Python3

The web application, but not (yet) the web API is also compatible with Python3. The support for Python3 for the web API is in the works.

Installation

git clone https://github.com/fginter/dep_search.git   
cd dep_search
git submodule init   
git submodule update   
make

Index and test a treebank

dep_search comes with the file example_en.conllu which contains a handful of sentences from UD English, so you can test the query tool:

cat example_en.conllu | python build_index.py --wipe -d example_en_db
python query.py '_ <nsubj _' --dblist example_en_db/*.db
