These are some implementations of text clustering algorithms, though only the implementation of Incremental Hierarchical Agglomerative Clustering (IHAC) has been polished and completed.

This project was put together specifically for Argos so some of the setup is tailored to that, though I eventually hope to make it a bit more general.

There is some prep you need to do for Pytables (the tables package):

pip install numexpr cython

# On OSX
brew tap homebrew/science
brew install hdf5

# On Linux
sudo apt-get install libhdf5-dev

There are other additional dependencies which you can install using the provided setup script.

Then you can install galaxy with either:

pip install git+git://github.com/ftzeng/galaxy

or clone this repo and then install it from there (useful if you are actively working on this project):

pip install --editable .

Note that you many need to manually upgrade the topia.termextract module to this git fork which is Py3 compatible:

 pip install -U git+git://github.com/BowdoinOrient/topia.termextract.git

Then you should configure things as needed (see the next section) and then train your pipelines:

$ python run.py train /path/to/training/data.json

This expects that the data is a list of dictionaries, with title and text keys. Depending on how much data you have, this could take a long time.

You can configure a few things by setting them on galaxy.conf:

conf.PIPELINE_PATH = where you pickled pipelines are stored.
conf.STANFORD      = a dict specifying the host & port of your Stanford NER server.
conf.SPOTLIGHT     = a dict specifying the host & port of your DBpedia Spotlight server.

You should set these before you load any of the other galaxy modules.

# Train the feature pipelines (text and concepts):
$ python run.py train /path/to/training/data.json

# Evaluate event clustering (on labeled data):
# The `--incremental` flag will break the input into chunks of random sizes.
$ python run.py eval /path/to/eval/data.json <approach> [--incremental]

# Run clustering on unlabeled data:
$ python run.py cluster /path/to/test/data.json

# Fix up encoding errors in data:
$ python run.py clean /path/to/data.json

Using the line_profiler package.

To measure speed, add the @profile decorator to any function you want to measure. Then run then script:

$ kernprof -lv run.py <your args>

Using the memory_profiler and psutil packages.

To measure memory usage, add the @profile decorator to any function you want to measure. Then run the script:

$ python -m memory_profiler run.py <your args>
