Building a Chatbot with Natural Language Processing

Introduction

In this project, we will explore how to build a chatbot that can communicate with websites using natural language. The chatbot will be Based on GPT technology and will utilize Lang Chain, Vector DBQA, web crawling, and Chroma DB to accomplish its tasks. In the following sections, we will discuss the step-by-step process of creating this chatbot and provide a demonstration of its functionality.

1. Overview of the Project

Before diving into the technical details, let's start with an overview of what we aim to achieve with this project. The primary goal is to build a question-answering chatbot that can Interact with websites using natural language. To accomplish this, we will first perform web crawling to extract text from the target website. We will then split and chunk the text into manageable portions. Next, we will generate embeddings for these text pieces using OpenAI. These embeddings will be stored in a Vector DB, specifically Chroma DB, for efficient retrieval. Finally, we will implement Lang Chain to enable the chatbot to provide accurate answers to user queries based on the extracted embeddings.

2. Building a Chatbot with Natural Language Processing

In this section, we will dive into the technical details of building the chatbot. We will cover each step of the process, from web crawling to question-answering capabilities.

2.1. Web Crawling and Text Extraction

The first step in building our chatbot is to perform web crawling and extract text from the target Website. Using web crawling tools like Advert Tools, we will fetch the website's content and store it in a JSON file. We can then use the pandas library to Read the JSON file and focus on the Relevant text columns, such as the body text and metadata. By concatenating these text columns, we can obtain a comprehensive corpus of text for further processing.

2.2. Text Splitting and Chunking

To enable efficient storage and retrieval of text, we need to split and chunk the extracted text. By setting a suitable chunk size and allowing for overlapping, we can divide the text into manageable chunks. This process ensures that no information is missed and allows for better organization of the text data. We can then convert these chunks into documents, ready for further processing.

2.3. Extracting Embeddings and Storing in Vector DB

Once we have the chunked text, we can generate embeddings using OpenAI. Embeddings capture the semantic meaning of the text and will be crucial for accurate question answering. These embeddings, along with the corresponding chunk text, will be stored in a Vector DB, namely Chroma DB. This storage solution allows for efficient retrieval of embeddings during the question-answering process.

2.4. Initializing and Using Lang Chain for Q&A

To enable the chatbot to answer questions based on the extracted text and embeddings, we need to initialize Lang Chain. Lang Chain is a powerful framework capable of performing semantic searches. By providing the Vector DB and specifying the chain Type as "stuff," we can construct a model for question answering. By querying the model with various questions, we can obtain accurate responses based on the stored embeddings.

3. Implementing the Chatbot

In this section, we will walk through the implementation of the chatbot by following the aforementioned steps.

3.1. Setting up Google Drive and Installing Libraries

Before we begin, we need to mount our Google Drive to facilitate text storage during web crawling. We will also need to install necessary libraries such as OpenAI, Lang Chain, Chroma DB, and others. These libraries provide the required functionalities for building our chatbot.

3.2. Specifying OpenAI Key

To use the OpenAI language model, we need to specify our OpenAI key. This key allows us to access the language model and generate embeddings for the extracted text.

3.3. Web Crawling with Advert Tools

Using Advert Tools, we will crawl the target website by providing its URL. We can specify parameters such as follow-link equal to "True" to explore subdomains and extract the desired text content. The resulting text will be stored in a JSON file.

3.4. Loading Data into Lang Chain

To leverage the functionalities of Lang Chain, we need to load the extracted text into Lang Chain's document load. Since we have pandas data frames, we can use the data frame load method and specify the body text as the main content. Any additional metadata can also be included.

3.5. Chunking and Storing Text in Vector DB

After loading the text into Lang Chain, we can proceed with text chunking. By setting appropriate chunk sizes and allowing for overlapping, we can divide the text corpus into smaller chunks for efficient storage. We can store these chunks in the Vector DB, along with their corresponding embeddings.

3.6. Creating and Running the Q&A Model

To Create the question-answering model, we need to initialize the Lang Chain with the vector DB. By specifying the chain type as "stuff" and providing the Vector DB, we can create the model capable of performing semantic searches. We can then use the model to run queries by providing questions and obtain accurate answers based on the extracted embeddings.

4. Conclusion

In this project, we have explored the process of building a chatbot that can communicate with websites using natural language. By leveraging web crawling, text extraction, chunking, and embedding generation, we were able to implement a capable question-answering model using Lang Chain and Vector DB. This chatbot has the potential to provide accurate and relevant answers based on the text from the target website.

5. FAQ
