paraphrase-id-tensorflow

Various models and code for paraphrase identification implemented in Tensorflow (1.1.0).

I took great care to document the code and explain what I'm doing at various steps throughout the models; hopefully it'll be didactic example code for those looking to get started with Tensorflow!

So far, this repo has implemented:

PR's to add more models / optimize or patch existing ones are more than welcome! The bulk of the model code resides in duplicate_questions/models

A lot of the data processing code is taken from / inspired by allenai/deep_qa, go check them out if you like how this project is structured!

Installation

This project was developed in and has been tested on Python 3.5 (it likely doesn't work with other versions of Python), and the package requirements are in requirements.txt.

To install the requirements:

pip install -r requirements.txt

Note that after installing the requirements, you have to download the necessary NLTK data by running (in your shell):

python -m nltk.downloader punkt

GPU Training and Inference

Note that the requirements.txt file specify tensorflow as a dependency, which is a CPU-bound version of tensorflow. If you have a GPU, you should uninstall this CPU TensorFlow and install the GPU version by running:

pip uninstall tensorflow
pip install tensorflow-gpu

Getting / Processing The Data

To begin, run the following to generate the auxiliary directories for storing data, trained models, and logs:

make aux_dirs

In addition, if you want to use pretrained GloVe vectors, run:

make glove

which will download pretrained Glove vectors to data/external/. Extract the files in that same directory.

Quora Question Pairs

To use the Quora Question Pairs data, download the dataset from Kaggle (may require an account). Place the downloaded zip archives in data/raw/, and extract the files to that same directory.

Then, run:

make quora_data

to automatically clean and process the data with the scripts in scripts/data/quora.

Running models

To train a model or load + predict with a model, then run the scripts in scripts/run_model/ with python <script_path>. You can get additional documentation about the parameters they take by running python <script_path> -h

Here's an example run command for the baseline Siamese BiLSTM:

python scripts/run_model/run_siamese.py train --share_encoder_weights --model_name=baseline_siamese --run_id=0

Here's an example run command for the Siamese BiLSTM with matching layer:

python scripts/run_model/run_siamese_matching_bilstm.py train --share_encoder_weights --model_name=siamese_matching --run_id=0

Here's an example run command for the BiMPM model:

python scripts/run_model/run_bimpm.py train --early_stopping_patience=5 --model_name=biMPM --run_id=0

Note that the defaults might not be ideal for your use, so feel free to turn the knobs however you like.
