Build a philosophy quote generator with vector search and astra db (part 2)

If you’re ready to dive deeper into building your own philosophy quote generator, this guide (Part 2A) will walk you through the essentials of vector search and Astra DB.

In this article about – Build a philosophy quote generator with vector search and astra db (part 2), we’ll continue exploring how to integrate advanced technologies to create a seamless experience for generating inspiring quotes.

After this one, we will cover Build a Philosophy Quote Generator with Vector Search and Astra DB (Part 3). You can visit and learn about the part 3.

For now, let’s focus on part 2.

Why Vector Search and Astra DB?

Vector search is a powerful method for retrieving contextually relevant data by leveraging embeddings, which capture the semantic meaning of text.

Combined with Astra DB’s scalable and serverless database capabilities, you can build an efficient, high-performing quote generator.

This setup allows you to:

• Quickly retrieve relevant quotes based on user input.
• Scale effortlessly as your quote database grows.
• Maintain a simple yet powerful architecture for your application.

Build a Philosophy Quote Generator with Vector Search and Astra DB (Part 2)

Step 1: Preparing Your Environment

Before you start coding, ensure you have:

• Astra DB account: Sign up if you don’t have one.
• Python installed: For implementing vector search and embedding generation.
• Quote dataset: A collection of philosophical quotes.

Step 2: Database Setup with Astra DB

1. Create a Keyspace: Use Astra DB to create a keyspace for storing your quotes.
2. Define Tables:sqlCopy codeCREATE TABLE philosophy_quotes ( id UUID PRIMARY KEY, quote TEXT, author TEXT, embedding VECTOR<FLOAT, 512> );
3. Insert Data: Populate your table with quotes and their respective embeddings.

Step 3: Implement Vector Search

Use a library like Sentence Transformers to generate embeddings for each quote.

pythonCopy codefrom sentence_transformers import SentenceTransformer  

# Load model  
model = SentenceTransformer('all-MiniLM-L6-v2')  

# Generate embedding  
quote = "The unexamined life is not worth living."
embedding = model.encode(quote)  

Store these embeddings in your Astra DB table.

Step 4: Querying with Vector Search

Implement a search function to retrieve quotes based on user input.

pythonCopy codedef search_quotes(user_input, top_k=5):
    user_embedding = model.encode(user_input)
    query = f"""
    SELECT quote, author FROM philosophy_quotes 
    ORDER BY embedding <-> {user_embedding} ASC LIMIT {top_k};
    """
    results = execute_query(query)
    return results

• Deploying your application to a cloud service.
• Optimizing vector search for better results.

Building your philosophy quote generator with vector search and Astra DB is a rewarding project. Stay tuned for Part 2B, where we’ll bring everything together.

Final Thoughts On build a philosophy quote generator with vector search and astra db (part 2)

Building a philosophy quote generator using vector search and Astra DB combines the power of semantic understanding with the scalability of a serverless database.

By leveraging embeddings, you can create a tool that retrieves contextually relevant quotes with precision, providing users with an enriching experience.

In Part 2A, we covered the foundational steps:

• Setting up Astra DB for storing quotes and embeddings.
• Generating embeddings using Sentence Transformers.
• Implementing vector search for meaningful results.

With these components in place, your project is on solid ground to deliver high performance and scalability.

Stay tuned for Part 2B, where we’ll complete the application by enhancing the user interface, deploying it to the cloud, and optimizing its functionality.
