Simple Way to Integrate LLMs into spaCy NLP Pipeline

Natural language processing(NLP) gets a major boost with the rise of Large language models(LLMs). Large language models can understand and generate human language opening doors for complex tasks like summarization and information extraction. In addition, it can be prompted to perform custom NLP tasks such as text categorization, named entity recognition, coreference resolution, information extraction, and many more.

The integration of LLMs into spaCy NLP Pipeline, we can use the power of LLM models in our NLP workflow. Here, in this blog, we explore the integration of LLMs into your spaCy pipeline. spaCy, a popular NLP library, offers robust tools for various language processing requirements. Combine spaCy's strengths with the flexibility of LLM prompting using the 'spacy-llm' library for rapid prototyping and enhanced NLP capabilities.

What is Large Language Models

Large Language Models are a type of Artificial Intelligence(AI) trained on massive amounts of text data. This data can include books, articles, code, and even conversations. With the vast amounts of information, LLMs learn the patterns and structures of language. It performs a variety of tasks, including:

• Text Generation: LLMS can generate various types of creative text, such as poems, code, scripts, music, emails, and letters.

• Machine Translation: LLMs can translate languages with greater accuracy and fluency than traditional machine translation methods.

• Answer the Question: LLMs can provide comprehensive answers to questions, even when the answer is not present in the trained text.

• Text Summarization: LLMs help to create concise summaries of lengthy pieces of text.

Basics of spaCy NLP Library

spaCy is a free, open-source, well-established NLP library in Python. It helps build systems that work with language in various ways. It can streamline the development of NLP pipelined. And it’s built-in components are powered by supervised learning or rule-based approaches.

"spaCy-llm" allows you to connect statistical models that are trained using popular machine-learning libraries such as TensorFlow, PyTorch, and MXNet. With its machine learning library, spaCy provides convolutional neural network models that are specifically designed for part-of-speech tagging, dependency parsing, text categorization, and named entity recognition.

spaCy-llm: The Bridge Between spaCy and LLMs

spaCy-llm is a library that bridges the gap between spaCy, a popular natural language processing (NLP) library, and Large Language Models (LLMs). It allows you to create pipelines with a mix of components. You can use LLMs for flexible tasks and other established spaCy components for efficient and accurate tasks.

As your project grows with mature data, you can refine your pipeline. You might replace LLM-powered components with custom-trained models for specific tasks if the data allows. This can improve performance and potentially reduce costs associated with LLM usage.

spaCy provides a mature and well-developed library with various components. These components are often more efficient and interpretable than LLMs which makes them ideal for pre-processing or refining LLM outputs.

Overall, it empowers you to find the right balance between the flexibility of LLMs and the efficiency of traditional NLP techniques. This can lead to cost-effective and high-performing NLP systems.

How to Integrate LLMs into spaCy NLP Pipeline

Let’s explore how to LLMs into spaCy NLP Pipeline. To achieve this, we will make use of the spaCy-llm library. In this example LLM provider will be OpenAI, however, it's important to note that other LLMs with compatible APIs can also be used with this approach.

Step 1: Install Required Libraries

Ensure you have spaCy (pip install spacy) and the spacy-llm extension (pip install spacy-llm) installed in your Python environment.

Step 2: Import Necessary Modules

For our example, we need to import spacy and os modules.

import spacy
import os

Step 3: Set Up Your LLM API Key

If you intend to use a cloud-based LLM, obtain an API key from the provider (e.g., OpenAI) and set the OPENAI_API_KEY environment variable:

os.environ["OPENAI_API_KEY"] = "your_api_key"  # Replace with your actual key

Step 4: Load a Blank spaCy Model (or Create a Custom One)

Create a blank spaCy nlp object to serve as the foundation for your custom pipeline:

try:
    nlp = spacy.blank("en")

Step 5: Create the NER Component and Add it to the Pipeline

Extend the nlp pipeline by adding the llm_ner component using nlp.add_pipe()

llm_ner = nlp.add_pipe("llm_ner")

Step 6: Define Entity Labels

Create a list of entity labels (labels) you want the LLM to identify in the text. Common examples include PERSON, LOCATION, ORG, etc. You can customize this list based on your specific use case.

labels = [ "PERSON", "LOCATION", "ORG", "DATE", "TIME", "MONEY", "PERCENT", "FAC", "GPE", "EVENT", "LAW", "LANGUAGE", "WORK_OF_ART", "PRODUCT", "QUANTITY" ]

Add each label to the llm_ner component using the add_label method

for label in labels:
        llm_ner.add_label(label)

Step 7: Initialize the spaCy Model

Execute nlp.initialize() to complete the configuration and ensure all components are ready for processing.

nlp.initialize()

Step 8: Prepare Your Text Input

Define the text you want to analyze (text). Ensure it's a string containing the content you wish to extract entities from.

text = "Pichai completed schooling in Jawahar Vidyalaya Senior Secondary School in Ashok Nagar, Chennai, and completed the Class XII from Vana Vani school at IIT Madras. He earned his degree from IIT Kharagpur in metallurgical engineering and is a distinguished alumnus of that institution. He holds an M.S. from Stanford University in materials science and engineering, and an MBA from the Wharton School of the University of Pennsylvania, where he was named a Siebel Scholar and a Palmer Scholar, respectively."

Now, Apply the nlp(text) function to process the input text using the spaCy pipeline, including the newly added LLM NER component. This will generate a Doc object containing the processed text and extracted entities.

doc = nlp(text)

Step 9: Extract and Print Entities

If desired, iterate through the doc.ents to retrieve the detected entities and their labels, printing them:

entities = [(ent.text, ent.label_) for ent in doc.ents]
 if entities:
     print(entities)
  else:
     print("No entities found in the text.")

Step 10: Error Handling

It is recommended to implement exception handling, such as try-except blocks, to gracefully handle potential errors that may occur during the LLM interaction or spaCy processing.

except Exception as e:
    print("An error occurred:", e)

By following these steps and considering these factors, you can effectively integrate LLMs into your spaCy pipeline for enhanced named entity recognition capabilities.

Benefits of Integrating LLMs into the spaCy NLP Pipeline
