Querying Custom Text and PDF Files Using Pinecone Lang Chain and OpenAI

In this article, we will explore how to query our own custom text and PDF files using Pinecone Lang Chain and OpenAI. By following the steps outlined below, You will be able to Create embeddings for your files and search for semantically similar documents using natural language models.

Step 1: Creating Embeddings for Custom Files

1. Splitting the File into Multiple Documents

When dealing with large files that exceed the token limit for OpenAI, the first step is to split the file into smaller chunks. By doing so, we ensure that our files can be processed effectively.

2. Creating Vector Embeddings with OpenAI's Embedding API

Once the file is split into smaller documents, we can use OpenAI's Embedding API to convert each document into vector embeddings. These embeddings capture the semantic meaning of the text and allow for efficient similarity searches.

3. Saving Vector Embeddings into Pinecone Vector Database

The next step is to save the vector embeddings into a Pinecone Vector Database. This allows us to store and retrieve the embeddings for querying purposes. By saving the embeddings in a database, we can easily search for similar documents Based on the embeddings' similarity.

Step 2: Querying Custom Files Using Natural Language Models

1. Converting Queries into Embeddings with OpenAI's Embedding API

To query our custom files using natural language models, we need to convert our queries into embeddings. This can be done using OpenAI's Embedding API. By converting the query into an embedding, we can search for semantically similar documents.

2. Searching for Similar Documents in Pinecone Database

After converting the query into an embedding, we can search the Pinecone Vector Database for documents that are semantically similar. This allows us to retrieve contextually aware results that match the query's intent.

3. Returning Contextually Aware Results with OpenAI LLM API

Finally, we can use the OpenAI LLM (Language Model) API to return contextually aware results. The LLM API responds using natural language, providing information that is Relevant and Meaningful to the query. This allows for a more interactive and human-like query experience.

Setting Up the Environment and Dependencies

Before getting started, ensure that you have installed the necessary dependencies such as Lang Chain, OpenAI, and Pinecone client. Additionally, make sure you have your OpenAI API Key and Pinecone API key handy, as they will be required for the setup.

Example: Querying a Text File

In the provided code notebook, you will find an example of how to query a text file using Lang Chain, Pinecone, and OpenAI. The example demonstrates the process of splitting the document into smaller chunks, creating vector embeddings, setting up the Pinecone index, and querying the file using natural language models.

Example: Querying a PDF File

Similarly, the code notebook also includes an example of how to query a PDF file. The process is quite similar to querying a text file but involves using the PDF loader from Lang Chain to load the PDF file. The rest of the steps, such as splitting the document, creating embeddings, and querying using natural language models, remain the same.

Conclusion

Querying custom text and PDF files using Pinecone Lang Chain and OpenAI is a powerful and efficient way to retrieve relevant information from large volumes of text. By following the steps outlined in this article, you can create embeddings for your files, search for semantically similar documents, and get contextually aware results using natural language models. Start using this approach today to enhance your text analysis and retrieval capabilities.
