BookNLP is an advanced natural language processing pipeline designed to work with books and lengthy documents. It encompasses a variety of functionalities like part-of-speech tagging, dependency parsing, entity recognition, and more. This article will guide you step-by-step on how to set up and use BookNLP effectively.

Installation of BookNLP

Before diving into the usage, let’s get BookNLP installed on your machine:

1. Create an Anaconda environment (optional). First, download and install Anaconda, then create and activate a fresh environment using:

sh
conda create --name booknlp python=3.7
conda activate booknlp

2. If you plan to use a GPU, ensure you have PyTorch installed for your system and CUDA version.
3. Next, install BookNLP and download the SpaCy model by executing:

sh
pip install booknlp
python -m spacy download en_core_web_sm

How to Utilize BookNLP

With the installation out of the way, it’s time to put BookNLP into action:

1. Start by importing BookNLP:

python
from booknlp.booknlp import BookNLP

2. Define your model parameters:

python
model_params = {
    'pipeline': 'entity,quote,supersense,event,coref',
    'model': 'big'
}

3. Create an instance of BookNLP and load your input and output directories:

python
booknlp = BookNLP('en', model_params)
input_file = 'input_dir/bartleby_the_scrivener.txt'
output_directory = 'output_dir/bartleby'
book_id = 'bartleby'
booknlp.process(input_file, output_directory, book_id)

Understanding the Output

Upon processing your text, BookNLP generates several files in the specified output directory. Each file serves a distinct purpose:

• $book_id.tokens: Contains core word-level information like token ID, POS tags, and more.
• $book_id.entities: Lists typed entities and their coreferences in the document.
• $book_id.supersense: Stores supersense tagging information.
• $book_id.quotes: Records identified quotations and their attributed speakers.
• $book_id.bookJSON: Information on characters including references and actions.
• $book_id.book.html: Full text of the document with annotations.

Code Analogy: Processing of Text as a Library System

Think of using BookNLP like running a library system:

Each step of processing is akin to sorting books in a library. When you check a book (the input text), you first place it in a specific section (defining model parameters), then librarians (BookNLP) carefully catalog the details (tokens, entities) into designated folders (output files). Just as librarians can extract particular information from books, you can specify which part of the analysis to run based on the needs of your research.

Troubleshooting Common Issues

While setting up and using BookNLP, you might encounter issues. Here are some troubleshooting tips:

• Ensure that your Python and Anaconda version is compatible, especially when creating environments.
• If your GPU isn’t being utilized, double-check your PyTorch installation and CUDA compatibility.
• For slower performance, consider switching to the smaller BookNLP model if the big model is not essential for your task.
• Make sure that the input file and output directory paths are correct and accessible.
