Unique: Implements multi-tier keyword frequency weighting (high/medium/low priority keywords) with regex pattern support and boolean AND/NOT logic, scoring articles by keyword match density rather than simple presence/absence checks

vs others: More flexible than simple keyword whitelisting (supports regex and exclusion rules) but simpler than ML-based relevance ranking, making it suitable for rule-driven curation without ML infrastructure
