Semantic Question Matching

A Tensorflow implementation of a BiLSTM-MaxPooling Siamese Network [1] for Paraphrase Detection on the Quora question pairs dataset [2]. The encoder can be pretrained with a Sequential Denoising Autoencoder (SDAE) to tackle the semi-supervised setting (as in [3]).

Requirements

The code is written in Python 3 with the following dependencies:

  • Tensorflow (== 1.4)
  • numpy
  • pandas
  • NLTK
  • Gensim

Docker

A Dockerfile with the corresponding GPU environment and jupyterlab is provided in /docker.

cd docker
nvidia-docker build -t sqm .
nvidia-docker run -it -p 8888:8888 -v <absolute_path>/:notebooks/ sqm

Data

cd data
unzip data.zip -d .
./get_glove.sh

This will unzip Quora's dataset and download GloVE.6B.
The provided split is the standard partition from [4] in the original Quora format.
None of question id and pair id match the original release from Quora.

Training

Supervised Siamese Network:

python training.py -m siamese

Semi-supervised SDAE-Siamese Network:

# -res is the size of the labeled seed of question pairs
python training.py -m hybrid -res 1000
