Robust, Scalable Detection of Text Containment in Large Web-Crawled Corpora
FindMyText is an open-source Python package designed for robust and scalable detection of text containment within large corpora. It utilizes a novel mechanism that captures sequences of matching document fingerprints to identify near-verbatim copies rather than just general textual similarity. The system leverages a distributed, disk-based indexing framework, enabling it to scale effectively to massive web-crawled datasets. Benchmarks across ArXiv, Wikipedia, and generic web content demonstrate

Why It Matters
This development provides a critical tool for copyright verification and plagiarism detection, addressing the growing need to monitor large-scale digital content for unauthorized use. For AI practitioners and researchers, it offers a scalable solution to ensure compliance and integrity when working with extensive web-crawled datasets.
Technical Details
- Core Mechanism: Extends traditional document fingerprinting by explicitly capturing chains of matching fingerprints, allowing for reliable identification of near-verbatim text segments.
- Scalability Architecture: Employs a distributed, disk-based indexing framework to handle the computational and storage demands of large web-crawled corpora.
- Performance Validation: Evaluated against a new benchmark dataset, showing superior performance compared to other methods across diverse sources including academic papers (ArXiv), encyclopedic content (Wikipedia), and general web text.
- Implementation: Delivered as an open-source Python package, facilitating integration into existing data processing pipelines.
Industry Insight
- Organizations managing large-scale data ingestion should adopt robust containment detection tools like FindMyText to mitigate legal risks associated with copyrighted material.
- The shift from simple similarity metrics to chain-based fingerprinting represents a significant improvement in precision for automated content moderation systems.
- As web crawls grow larger, disk-based distributed indexing will become a standard requirement for real-time or near-real-time text verification tasks.
