In this repo we implemented a pointer generator network (see figure below) from the paper Get To The Point: Summarization with Pointer-Generator Networks.

We provide here some of the main obtained results and not in a Jupyter Notebook since the most meaningful results are shown in here and running a model inside of a notebook, is impossible due to its size and the size of the dataset.

In order to install the needed packages run:

pip install -r requirements.txt

However in order to be able to compute the ROUGE score you will need to install it (instructions can be found here).

To get the data, download the CNN_STORIES_TOKENIZED and DM_STORIES_TOKENIZED from here. Then prepare the data by running preprocess_data.py.

The vocab file used can be downloaded here.

The pointer generator can be found in the file model.py. However, note that the model is composed of an encoder and decoder that are then used inside the object PointerGenerator.

_{Note that the data we used to evaluate the model hasn't been prepared like in the paper so the results cannot be compared.}
