ISCC Codes for Amazon Book Covers

Amazon book covers enriched with full 256-bit ISCC (International Standard Content Code) identifiers for cover image identification, similarity search, and deduplication research. The image_url field links to cover images on Amazon CDN for preview.

What is ISCC?

The International Standard Content Code (ISO 24138:2024) is a content-derived identifier for digital media assets. Unlike traditional identifiers that are assigned arbitrarily, ISCC codes are generated algorithmically from the content itself, enabling:

Content Identification: Identify content regardless of format or location
Similarity Search: Find visually or semantically similar images
Deduplication: Detect exact and near-duplicate content
Provenance Tracking: Link derived works to their sources

ISCC Units

Each record contains five 256-bit ISCC-UNITs that capture different aspects of the content:

Unit	Field	Description
Meta-Code	`iscc_meta`	Similarity based on embedded metadata (filename, title)
Semantic-Code	`iscc_semantic`	AI-based visual semantic similarity (what the image depicts)
Content-Code	`iscc_content`	Perceptual image similarity (visual appearance)
Data-Code	`iscc_data`	Raw binary data similarity (file structure)
Instance-Code	`iscc_instance`	Cryptographic hash for exact matching (like SHA-256)

The iscc field contains the composite ISCC-CODE combining all units.

Usage

Loading the Dataset

from datasets import load_dataset

ds = load_dataset("iscc/iscc-book-covers")

Viewing a Sample

sample = ds["train"][0]
print(f"ISCC: {sample['iscc']}")
print(f"Title: {sample['title']}")

Similarity Search Example

import iscc_core as ic

# Get two ISCC codes to compare
code1 = ds["train"][0]["iscc_content"]
code2 = ds["train"][1]["iscc_content"]

# Calculate hamming distance (0 = identical, 256 = maximally different)
distance = ic.iscc_distance(code1, code2)
print(f"Hamming distance: {distance}")

# Convert to similarity percentage
similarity = 1 - (distance / 256)
print(f"Similarity: {similarity:.1%}")

Finding Near-Duplicates

import iscc_core as ic

# Threshold for near-duplicates (adjust based on use case)
THRESHOLD = 32  # ~87.5% similarity

reference = ds["train"][0]["iscc_content"]

for i, row in enumerate(ds["train"]):
    distance = ic.iscc_distance(reference, row["iscc_content"])
    if distance <= THRESHOLD and i > 0:
        print(f"Near-duplicate found: row {i}, distance={distance}")

Semantic Similarity Search

import iscc_core as ic

# Find semantically similar images (same subject/concept)
reference = ds["train"][0]["iscc_semantic"]

similar = []
for i, row in enumerate(ds["train"]):
    distance = ic.iscc_distance(reference, row["iscc_semantic"])
    if distance <= 64:  # ~75% semantic similarity
        similar.append((i, distance))

# Sort by similarity
for idx, dist in sorted(similar, key=lambda x: x[1])[:5]:
    print(f"Row {idx} (distance={dist})")

Source Data

This dataset was derived from cogsci13/Amazon-Reviews-2023-Books-Meta.

Source Data

Book metadata from the Amazon Reviews 2023 dataset by McAuley Lab. Cover images hosted by Amazon CDN. This derivative dataset contains ISCC codes and references to the original images, not the images themselves. License: Research use only. Refer to original dataset terms.

Processing

ISCC codes were generated using:

iscc-sdk - High-level ISCC generation
iscc-sci - Semantic image codes (experimental)

All processing was performed on original resolution images downloaded from Amazon CDN.

Considerations

Intended Use

Content identification and matching research
Image similarity search algorithm development
Deduplication system benchmarking
Visual-semantic retrieval experiments
ISCC-based indexing research

Limitations

Semantic codes are generated using experimental AI models and may not capture all semantic nuances
ISCC codes are sensitive to significant image modifications (heavy cropping, overlays, filters)
Image URLs point to Amazon CDN and may become unavailable over time

Privacy

This dataset contains ISCC codes and image URL references derived from the source dataset. Refer to the original dataset documentation for privacy considerations.
