Discover Your Next Read with Book Aura: An AI-Powered Literary Companion Built on MindsDB Knowledge Bases

In a world brimming with books, finding your next captivating read can often feel overwhelming. Traditional search methods often fall short when you're looking for something specific but can only recall a vague theme, a particular mood, or a general concept. This is where Book Aura steps in – an intelligent book discovery platform designed to connect you with your perfect book, effortlessly.

I'm excited to share Book Aura, a project developed for the MindsDB Quest 019, which focuses on stress-testing MindsDB's powerful Knowledge Bases. Book Aura leverages MindsDB's cutting-edge semantic search, AI Tables, and Agents to transform your reading preferences into precise book recommendations and deep literary insights.

Why MindsDB Knowledge Bases?

MindsDB is an AI data solution that empowers users to query data using natural language and SQL across diverse data sources. Their recently released Knowledge Bases are a game-changer, offering semantic search capabilities that allow you to store and retrieve information based on its meaning, rather than just keywords. This semantic understanding is crucial for Book Aura, enabling it to go beyond simple keyword matching and truly understand your reading preferences.

Introducing Book Aura: Your Intelligent Book Companion

Book Aura is more than just a search engine; it's a comprehensive literary experience crafted for book lovers. Here's what makes it unique:

  • AI Layer: MindsDB orchestrates the core AI functionalities, including Knowledge Base queries, Agent interactions, and semantic search.
  • Data Layer: Manages book metadata, category classification, and relevance scoring.

Building Book Aura: A Deep Dive into MindsDB Integration

The integration of MindsDB is fundamental to every intelligent feature within Book Aura. Here’s a glimpse into how different MindsDB capabilities are utilized:

1. Intelligent Book Discovery with Knowledge Bases

At the heart of Book Aura's search is a MindsDB Knowledge Base, which stores over 1,200 book descriptions. This allows the application to understand the context, mood, and preferences of your query, going beyond simple keyword matching.

The FastAPI backend connects to MindsDB and executes semantic queries:

# mindsdb_sdk connection and setup (simplified)
con = mindsdb_sdk.connect('http://127.0.0.1:47334')
project = con.get_project('mindsdb')

@app.post("/book_search", response_model=list[BookSearchResponse])
async def book_search(request: BookSearchRequest):
    try:
        escaped_query = escape_sql_string(request.query)
        query = f"SELECT * FROM book_kb_1000 WHERE content = '{escaped_query}'"
        if request.category:
            query += f" AND category = '{escape_sql_string(request.category)}'"
        query += " LIMIT 3;"

        result = project.query(query)
        rows = result.fetch()
        # ... (response parsing)
        return results
    except Exception as e:
        logger.error(f"Book search failed: {e}")
        raise HTTPException(status_code=500, detail=str(e))
Enter fullscreen mode Exit fullscreen mode

This Python code snippet demonstrates how the FastAPI endpoint constructs a SQL query to the book_kb_1000 Knowledge Base, allowing for semantic search and optional filtering by category.

2. AI-Powered Literary Expert with MindsDB Agents

The interactive "Literary Expert Chat" is powered by a custom conversational agent created within MindsDB. This agent is designed to provide thoughtful analysis, interpretations, and discussions about books, drawing from its deep literary knowledge.

@app.post("/book_bot")
async def book_bot_query(request: BookBotRequest):
    try:
        q = f"""
            SELECT answer
            FROM book_bot
            WHERE
              book_name = '{escape_sql_string(request.book_name)}'
              AND description = '{escape_sql_string(request.summary)}'
              AND question = '{escape_sql_string(request.question)}';
        """
        logger.info(f"Running book_bot query: {q}")
        result = project.query(q)
        rows = result.fetch()
        # ... (response handling)
        return {"answer": rows.iloc[0]["answer"]}
    except Exception as e:
        logger.error(f"Book bot failed: {e}")
        raise HTTPException(status_code=500, detail=str(e))
Enter fullscreen mode Exit fullscreen mode

The /book_bot endpoint in FastAPI queries the book_bot MindsDB Agent, passing the book's name, summary, and the user's question to get a contextual answer.

3. Enriched Book Information with MindsDB AI Tables

To provide comprehensive book details, Book Aura utilizes MindsDB AI Tables. These tables dynamically generate enriched metadata such as author information, publication dates, smart tags, target audience, and more.

@app.post("/enriched_book_info")
async def enriched_book_info_query(request: EnrichedBookInfoRequest):
    try:
        q = f"""
            SELECT response
            FROM enriched_book_info
            WHERE
              book_name = '{escape_sql_string(request.book_name)}'
              AND description = '{escape_sql_string(request.summary)}'
              AND category = '{escape_sql_string(request.category)}';
        """
        logger.info(f"Running enriched_book_info query: {q}")
        result = project.query(q)
        rows = result.fetch()
        # ... (response handling)
        return {"response": rows.iloc[0]["response"]}
    except Exception as e:
        logger.error(f"Enriched book info failed: {e}")
        raise HTTPException(status_code=500, detail=str(e))
Enter fullscreen mode Exit fullscreen mode

The /enriched_book_info endpoint queries the enriched_book_info MindsDB Model (an AI Table), which takes the book's name, description, and category to generate a rich set of details.

4. Data Freshness with MindsDB Jobs

To ensure the Knowledge Base remains up-to-date with new books, a MindsDB JOB is scheduled to periodically check for and ingest new data from the source Google Sheet.
