The wealth of information available at our fingertips is both a blessing and a challenge. To tackle this, researchers have developed algorithms that assist in summarizing documents efficiently. One notable approach is the method described in the ACL 2018 paper “Neural Document Summarization by Jointly Learning to Score and Select Sentences.” This blog post walks you through how to set up and run the NeuSum code repository.

Step-by-Step Guide to Running NeuSum

1. Prepare the Dataset and Code

First, you need to create a workspace to house your code and the dataset. Follow these steps:

bash
NEUSUM_HOME=~workspaceneusum
mkdir -p $NEUSUM_HOME/code
cd $NEUSUM_HOME/code
git clone --recursive https://github.com/magic282/NeuSum.git

After preparation, your workspace should look like this:

neusum
├── code
│   └── NeuSum
│       ├── neusum_pt
│       └── neusum
├── PyRouge
└── data
    ├── cnndm
    ├── dev
    ├── glove
    ├── models
    └── train

This project uses the CNN Daily Mail dataset, which you can learn more about here: About the CNN Daily Mail Dataset and About the CNN Daily Mail Dataset 2.

2. Setting Up the Environment

Ensure you have the necessary packages:

• nltk
• numpy
• pytorch

Warning: Older versions of NLTK may have a bug in the PorterStemmer, so it is recommended to either install or update NLTK.

3. Using Docker

If you prefer using Docker, you can pull the provided image:

bash
docker pull magic282/pytorch:0.3.0

4. Run Training

Now you’re ready to run the training. There is a script file named run.sh that acts as a model. Adjust it according to your needs. You can run it in two ways:

Without Docker:

bash
$NEUSUM_HOME/code/NeuSum/neusum_pt/run.sh $NEUSUM_HOME/data/cnndm $NEUSUM_HOME/code/NeuSum/neusum_pt

With Docker:

bash
nvidia-docker run --rm -ti -v $NEUSUM_HOME:/workspace magic282/pytorch:0.3.0

Then, inside the Docker container, run:

bash
bash code/NeuSum/neusum_pt/run.sh workspace/data/cnndm workspace/code/NeuSum/neusum_pt

Understanding the Code Setup with an Analogy

Setting up NeuSum is much like organizing a library to maximize efficiency:

• The Workspace: Think of your workspace as a library’s main hall where all the books (data) and resources (code) are housed. You start by creating shelves (folders) for different genres (components of your project).
• Installation of Books: Just like you would ensure all the necessary books are correctly categorized and updated (installing the required packages), you have to gather your resources to avoid confusion later.
• Reading and Research: When you run the training script, it is akin to opening a book to learn new topics efficiently. The script compiles and processes the information just like a librarian organizing borrowed books.

Troubleshooting Tips

If you encounter any issues during the setup process, here are a few things to check:

• Ensure all paths are correctly specified and that you have the necessary permissions.
• If the packages fail to install, check your internet connection or consider a different package manager.
• Keep an eye on error messages. They often provide clues about what went wrong.
• Review the configuration in run.sh. Small misconfigurations can lead to failure.
