🎯 Special Feature: RAG-Optimized Field

What is canonical_embedding_text?

This dataset includes a custom-engineered semantic field specifically optimized for modern Retrieval-Augmented Generation (RAG) systems, vector databases, and embedding models.

Instead of raw columns, this field contains:

✨ A carefully blended, context-rich representation of each anime entry, built from multiple metadata sources and structured for maximum semantic clarity.

Why this field is special

• Embedding-ready out of the box - no preprocessing required
• Built using a proprietary formatting pipeline used in AiMi (愛視) Recommendation System
• Balances plot, characterization, genre cues, and contextual metadata
• Consistent across all 8,248+ anime entries
• Significantly boosts similarity accuracy compared to plain synopsis or tags

🛠️ How to Create RAG Embeddings

While the commercial version of AiMi includes a pre-engineered canonical_embedding_text field (optimized via a proprietary 12-step prompt pipeline), you can easily build your own high-quality embedding context using the metadata provided in this sample.

To get excellent results with models like Nomic v1.5 or OpenAI text-embedding-3, I recommend concatenating the core metadata columns into a structured string.

Python Example:

# 1. Create a rich context string for each anime
# This combines the Title, Visual Description, and Semantic Tags
df['rag_context'] = (
    "Title: " + df['Main Title'] + " | " +
    "Studio: " + df['Animation Work'].fillna('Unknown') + " | " +
    "Tags: " + df['processed_tags'].fillna('') + " | " +
    "Synopsis: " + df['Synopsis'].fillna('')
)

# 2. Inspect the result
print(df['rag_context'].iloc[0])
# Output: "Title: Attack on Titan | Studio: Wit Studio | Tags: action, military... | Synopsis: Humanity lives..."

# 3. Pass this new column to your embedding model!
embeddings = model.encode(df['rag_context'].tolist())

Use Cases

canonical_embedding_text allows you to:

• Build a semantic anime search engine
• Create embeddings directly with your preferred model
• Construct vector databases (FAISS, hnswlib, Pinecone, Weaviate, ChromaDB)
• Train retrieval or recommendation systems
• Experiment with natural language–based similarity querying

And all of this is possible without knowing the internal data fusion method.

💡 Creative Applications

1. 🎟️ Anime Receipt Generator (Trending Idea!)

Create beautiful two-sided anime "receipts" like movie tickets - a viral social media trend!

Front Side (Receipts):

Back Side (Receipts):

Implementation tip: Use Python's PIL/Pillow or web canvas to generate these programmatically. Perfect for a viral Twitter bot or Instagram account!

🛠️ Example Usage

Quick Start: Load the Data

import pandas as pd

# Load sample dataset
df = pd.read_csv('anime_sample_500.parquet')

# Basic exploration
print(f"Total anime: {len(df)}")
print(f"Columns: {df.columns.tolist()}")
print(f"Date range: {df['filter_year'].min()} - {df['filter_year'].max()}")

# View a sample entry
df.iloc[0][['Main Title', 'synopsis', 'Max Rating']]

Example 1: Simple Filtering

# Find highly-rated modern anime
modern_classics = df[
    (df['filter_year'] >= 2015) & 
    (df['Max Rating'] >= 8.0)
]

print(f"Found {len(modern_classics)} highly-rated modern anime")

Example 2: Text Analysis

from collections import Counter

# Most common tags
all_tags = []
for tags in df['processed_tags'].dropna():
    all_tags.extend([t.strip() for t in tags.split(',')])

top_10_tags = Counter(all_tags).most_common(10)
print("Most common anime themes:")
for tag, count in top_10_tags:
    print(f"  {tag}: {count}")

Example 3: Building Embeddings (RAG)

from sentence_transformers import SentenceTransformer

# Load embedding model
model = SentenceTransformer('nomic-ai--nomic-embed-text-v1.5')

# Use the RAG-optimized field
# Build your own embedding text from descriptive columns
# Example: df['canonical_embedding_text'] = df['Main Title'] + " " + df['Synopsis']
embedding_texts = df['canonical_embedding_text'].tolist()

# Generate embeddings
embeddings = model.encode(embedding_texts, show_progress_bar=True)

print(f"Generated {len(embeddings)} embeddings of dimension {embeddings.shape[1]}")

Example 4: Semantic Search

import numpy as np
from sklearn.metrics.pairwise import cosine_similarity

# User query
query = "dark fantasy anime with strong female protagonist"
query_embedding = model.encode([query])

# Find most similar anime
similarities = cosine_similarity(query_embedding, embeddings)[0]
top_indices = np.argsort(similarities)[-10:][::-1]

print("Top 10 recommendations:")
for idx in top_indices:
    print(f"  {df.iloc[idx]['Main Title']} (similarity: {similarities[idx]:.2f})")
