Detects personally identifiable information, protected health information, payment card data, and confidential company information across 50+ entity types by analyzing semantic context rather than pattern matching alone. Unlike regex-based approaches, the system reads contextual relationships between tokens to distinguish legitimate uses of PII-like strings (e.g., 'John' as a common noun vs. a person's name) and handles real-world data quality issues including ASR errors, OCR mistakes, handwritten forms, and conversational disfluencies. Supports 52 languages including code-switching scenarios.
Unique: Uses contextual semantic analysis ('reads context' per product claims) rather than pattern matching to detect PII, enabling accurate identification even with ASR errors, OCR mistakes, and conversational disfluencies where regex-based tools fail. Handles code-switching and 52 languages natively.
vs alternatives: Achieves 99.5% accuracy on physician conversations (Providence Health case study) vs. AWS Comprehend, Microsoft Presidio, and Google DLP which reportedly drop to 60-70% accuracy on real-world noisy data.
Redacts, pseudonymizes, or synthetically replaces detected PII entities across text, documents, images, and audio using configurable transformation strategies. The system applies entity-specific redaction rules (e.g., masking credit card numbers with asterisks, replacing names with consistent pseudonyms, generating synthetic replacements) while preserving document structure and downstream usability. Supports batch processing across multiple file formats (PDF, DOCX, XLS, XLSX, PPTX, XML, JSON, CSV) and image formats (TIFF, PNG, JPEG with OCR-based redaction).
Unique: Applies context-aware redaction across multiple modalities (text, documents, images, audio) with entity linking to maintain consistency across related documents — e.g., the same person's name is replaced with the same pseudonym throughout a dataset. Handles structured formats (JSON, CSV, XML) with schema-aware redaction.
vs alternatives: Supports multi-format document redaction (PDF, DOCX, spreadsheets, presentations) in a single API call, whereas most PII tools require separate pipelines for text vs. documents vs. images.
Detects PII across 52 languages including support for code-switching (mixing multiple languages within the same document or conversation). The system handles language-specific entity formats (e.g., different date formats, phone number patterns, address structures across countries) and recognizes PII in multilingual contexts without requiring explicit language specification. Supports real-world multilingual data including conversational transcripts with language mixing.
Unique: Supports PII detection across 52 languages including code-switching (language mixing) without requiring explicit language specification, handling language-specific entity formats and multilingual contexts natively.
vs alternatives: Enables code-switched and multilingual PII detection vs. language-specific tools (AWS Comprehend supports ~10 languages, Google DLP is English-focused) which require separate processing per language or fail on code-switched text.
Detects and redacts PII in images and scanned documents by performing optical character recognition (OCR) to extract text and then applying context-aware PII detection to the extracted content. The system handles real-world image quality issues including poor resolution, skewed text, handwritten annotations, and partial visibility. Supports TIFF, PNG, and JPEG formats and can redact detected PII directly in the image output.
Unique: Combines OCR with context-aware PII detection to handle scanned documents and images, including handwritten forms and poor-quality scans, with direct image redaction output preserving document structure.
vs alternatives: Enables end-to-end image PII detection and redaction vs. separate OCR + text PII tools which require manual integration and intermediate text extraction steps.
Detects PII in audio files and speech transcripts by handling automatic speech recognition (ASR) errors, conversational disfluencies, and real-world speech patterns. The system recognizes that ASR output contains errors and uses contextual analysis to identify PII despite transcription mistakes (e.g., 'John' transcribed as 'Jon', 'Smith' as 'Smyth'). Supports audio file input and transcript text with conversational patterns including filler words, interruptions, and informal speech.
Unique: Detects PII in audio and transcripts while handling ASR errors and conversational disfluencies, achieving 99.5% accuracy on physician conversations (Providence Health case study) despite speech recognition imperfections.
vs alternatives: Handles ASR-corrupted transcripts with context-aware detection vs. text-only PII tools which fail when applied to noisy ASR output with transcription errors.
De-identifies structured data formats (JSON, XML, CSV) by applying schema-aware redaction that preserves data structure and enables downstream processing. The system understands structured data schemas and applies entity-specific redaction rules to relevant fields while maintaining referential integrity and data relationships. Supports nested structures, arrays, and complex data hierarchies.
Unique: Applies schema-aware de-identification to structured data formats (JSON, XML, CSV) preserving data structure and relationships while redacting PII, enabling downstream processing and analytics on de-identified structured data.
vs alternatives: Maintains structured data integrity during de-identification vs. text-based PII tools which treat structured data as plain text and may corrupt structure or break relationships.
Connects related PII entities across multiple documents and extracts relationships between detected entities to maintain data consistency and enable entity resolution. The system identifies when the same person, organization, or account appears across different documents (e.g., matching 'John Smith' in one document with 'J. Smith' in another) and tracks relationships (e.g., 'patient John Smith was treated by Dr. Jane Doe'). This enables consistent pseudonymization where the same entity receives the same replacement across a dataset.
Unique: Performs cross-document entity linking to maintain pseudonymization consistency — the same entity receives the same replacement across a dataset. Extracts relationships between entities to enable knowledge graph construction while preserving privacy through consistent entity replacement.
vs alternatives: Enables consistent de-identification across multi-document datasets where standard PII tools would independently redact each document, potentially creating inconsistent pseudonyms for the same entity.
Deploys the de-identification engine as a containerized service within customer infrastructure (on-premises or customer VPC) ensuring sensitive data never leaves the customer's network. The system runs as a Docker container in the customer's environment, processes data locally, and returns only de-identified results. This architecture enables compliance with strict data residency requirements (HIPAA, GDPR, CCPA) and eliminates data transmission risk to third-party servers.
Unique: Provides containerized on-premises deployment where sensitive data never leaves customer infrastructure — data is processed locally and only de-identified results are returned. Enables compliance with strict data residency and data sovereignty requirements without relying on cloud infrastructure.
vs alternatives: Eliminates data transmission risk vs. cloud-based PII detection services (AWS Comprehend, Google DLP) which require sending sensitive data to external servers, making it suitable for highly regulated industries with strict data residency mandates.

Automated pipeline that scans source code for personally identifiable information (email addresses, API keys, SSH keys, credit card patterns, phone numbers) and removes or redacts them before dataset release. Uses regex patterns, entropy-based detection for secrets, and heuristic rules to identify sensitive data. Operates at file level with configurable sensitivity thresholds to balance data utility against privacy risk.
Unique: Combines regex pattern matching, entropy-based secret detection, and heuristic rules in a unified pipeline with configurable sensitivity — more comprehensive than simple regex-only approaches, but trades off false positive rate against security coverage
vs alternatives: More thorough than GitHub's secret scanning (which only flags known patterns) because it includes entropy-based detection for unknown secret formats, but less accurate than specialized tools like TruffleHog due to language-agnostic approach
Indexes 67 TB of source code across 600+ programming languages with language-aware metadata (syntax, file extension, language family). Enables retrieval by language, license, repository, or code patterns. Uses Software Heritage's existing indexing infrastructure as foundation, augmented with language detection and classification. Supports both bulk download and filtered queries for specific language subsets.
Unique: Leverages Software Heritage's existing language detection and indexing infrastructure, then augments with BigCode-specific language classification and filtering — avoids reinventing language detection while providing dataset-specific query capabilities
vs alternatives: More comprehensive language coverage (600+ languages) than GitHub's Linguist (500+ languages) and more accessible than Software Heritage's raw API because it's pre-filtered for permissive licenses and deduplicated
Removes duplicate code files and repositories using content hashing (SHA-256 or similar) and fuzzy matching for near-duplicates. Operates in two stages: exact deduplication via hash matching, then fuzzy matching (e.g., Jaccard similarity or MinHash) to catch semantically identical code with minor formatting differences. Preserves one canonical copy of each unique code pattern while removing redundant training examples.
Unique: Two-stage deduplication combining exact hash matching with fuzzy similarity matching (likely MinHash or Jaccard) to catch both identical and near-identical code — more thorough than single-stage approaches but computationally expensive
vs alternatives: More aggressive deduplication than CodeSearchNet (which uses simple hash matching) because it catches near-duplicates, but less semantic than clone detection tools (which understand code structure) because it's content-based
Integrates with Software Heritage's comprehensive archive of 200+ million repositories and their full version control history. Extracts source code snapshots from Software Heritage's Git/Mercurial/SVN repositories, preserving repository metadata (commit history, author info, timestamps). Provides access to code at specific points in time, enabling historical analysis or training on code evolution patterns.
Unique: Leverages Software Heritage's universal code archive (200M+ repositories) as data source, providing access to code that would be impossible to collect via GitHub API alone — enables training on archived/deleted repositories and non-GitHub platforms (GitLab, Gitea, etc.)
vs alternatives: More comprehensive than GitHub-only datasets because it includes code from GitLab, Gitea, SourceForge, and other platforms archived by Software Heritage; more legally defensible than web scraping because it uses an established, community-maintained archive
Tracks and validates SPDX license identifiers for each repository, ensuring only permissively licensed code (MIT, Apache 2.0, BSD, etc.) is included. Maintains license metadata alongside code files, enabling downstream users to verify legal compliance. Implements license hierarchy and compatibility checking to handle dual-licensed or complex licensing scenarios.
Unique: Combines automated SPDX detection with manual review and maintains license metadata alongside code, enabling downstream users to verify compliance — more transparent than datasets that simply claim 'permissive licenses' without proof
vs alternatives: More legally rigorous than GitHub's CodeSearchNet (which doesn't validate licenses) and more transparent than Codex training data (which doesn't disclose license filtering at all)
Maintains versioned snapshots of the dataset (e.g., v2.0, v2.1) with documented changes between versions (new repositories added, deduplication improvements, PII removal updates). Provides checksums and manifests for reproducibility, enabling researchers to cite specific dataset versions and reproduce results. Tracks dataset lineage and transformation history.
Unique: Maintains semantic versioning and detailed changelogs for dataset releases, enabling researchers to cite specific versions and understand dataset evolution — more rigorous than one-off dataset releases without versioning
