clssck	69358d830d	test(lightrag,examples,api): comprehensive ruff formatting and type hints ... Format entire codebase with ruff and add type hints across all modules: - Apply ruff formatting to all Python files (121 files, 17K insertions) - Add type hints to function signatures throughout lightrag core and API - Update test suite with improved type annotations and docstrings - Add pyrightconfig.json for static type checking configuration - Create prompt_optimized.py and test_extraction_prompt_ab.py test files - Update ruff.toml and .gitignore for improved linting configuration - Standardize code style across examples, reproduce scripts, and utilities	2025-12-05 15:17:06 +01:00
clssck	48c7732edc	feat: add automatic entity resolution with 3-layer matching ... Implement automatic entity resolution to prevent duplicate nodes in the knowledge graph. The system uses a 3-layer approach: 1. Case-insensitive exact matching (free, instant) 2. Fuzzy string matching >85% threshold (free, instant) 3. Vector similarity + LLM verification (for acronyms/synonyms) Key features: - Pre-resolution phase prevents race conditions in parallel processing - Numeric suffix detection blocks false matches (IL-4 ≠ IL-13) - PostgreSQL alias cache for fast lookups on subsequent ingestion - Configurable thresholds via environment variables Bug fixes included: - Fix fuzzy matching false positives for numbered entities - Fix alias cache not being populated (missing db parameter) - Skip entity_aliases table from generic id index creation New files: - lightrag/entity_resolution/ - Core resolution module - tests/test_entity_resolution/ - Unit tests - docker/postgres-age-vector/ - Custom PG image with pgvector + AGE - docker-compose.test.yml - Integration test environment Configuration (env.example): - ENTITY_RESOLUTION_ENABLED=true - ENTITY_RESOLUTION_FUZZY_THRESHOLD=0.85 - ENTITY_RESOLUTION_VECTOR_THRESHOLD=0.5 - ENTITY_RESOLUTION_MAX_CANDIDATES=3	2025-11-27 15:35:02 +01:00
