Introduction

In recent months, the integration of charity chatbots on websites has become increasingly popular. However, finding reliable resources for training chatbots, especially ones that can be trained on specific documents like PDFs, has proven to be a challenge. In this article, we will explore how to Create a chatbot that can be trained on your own documents, such as PDFs, using Python and OpenAI API.

The Need for Training Chatbots on Documents

Chatbots have become an essential tool for many businesses and organizations to provide information and support to their users. However, the ability to train these chatbots on specific documents, such as PDFs, allows for more accurate and targeted responses. Training chatbots on documents enables them to provide detailed information, answer specific questions, and even summarize the content of the documents.

Creating a PDF Chatbot

To create a PDF chatbot, we will be using Python and the OpenAI API. The first step is to extract the text from the PDF and split it into manageable chunks. This is necessary because the OpenAI API has a token limit, and we need to split the text into chunks to fit within this limit.

Extracting Text from a PDF

To extract text from a PDF, we will use the Lang Chain library. This library allows us to load the PDF and split the text into chunks. By specifying the chunk size, overlap, and length, we can ensure that the Context is not lost within the chunks.

Splitting Text into Chunks

Splitting the text into chunks is important because the OpenAI API has a token limit. By splitting the text into smaller chunks, we can pass the Relevant chunks to the API to get accurate answers. The chunk size and overlap can be adjusted Based on the requirements of your chatbot.

Embedding Text using OpenAI API

Once we have the chunks of text, the next step is to embed the text using the OpenAI API. Embedding the text converts it into a numerical vector representation. We will iterate through each chunk, call the OpenAI API's get embedding function, and store the embeddings in a dictionary.

Vector Similarity Calculation

To determine the similarity between two vectors, we can calculate their dot product. This will allow us to compare the similarity between the embeddings of different chunks and find the most relevant sections of the document for a given query.

Ordering Document Sections by Query Similarity

After calculating the similarity between the vectors, we can order the document sections based on their similarity to the query. This will provide us with the most relevant sections of the document that can be used to construct the prompt for the chatbot.

Set Parameters for OpenAI Completions API

Before using the OpenAI completions API, we need to set certain parameters. These parameters include the temperature, max token limit, and the model to be used. By adjusting these parameters, we can control the creativity and accuracy of the chatbot's responses.

Constructing the Prompt

To construct the prompt for the chatbot, we combine the query with the relevant context sections from the PDF. This prompt is then passed to the OpenAI completions API to generate a response.

Uploading and Using the PDF Chatbot Interface

The final step is to upload the PDF file and use the chatbot interface. The interface will display the uploaded file and provide a chatbot-like experience. When a query is submitted, the chatbot will retrieve the relevant context from the PDF and generate a response based on the query.

Conclusion

Creating a chatbot that can be trained on specific documents, like PDFs, opens up a world of possibilities for businesses and organizations. By following the steps outlined in this article, You can create your own PDF chatbot using Python and the OpenAI API. This chatbot will be able to provide accurate and detailed responses based on the content of the documents.
