Crawls 11+ Chinese social platforms (Zhihu, Weibo, Bilibili, Douyin, etc.) and RSS feeds simultaneously, normalizing heterogeneous data schemas into a unified NewsItem model with platform-agnostic metadata. Uses platform-specific adapters that extract title, URL, hotness rank, and engagement metrics, then merges results into a single deduplicated feed ordered by composite hotness score (rank × 0.6 + frequency × 0.3 + platform_hot_value × 0.1).
Unique: Implements platform-specific adapter pattern with 11+ crawlers (Zhihu, Weibo, Bilibili, Douyin, etc.) plus RSS support, normalizing heterogeneous schemas into unified NewsItem model with composite hotness scoring (rank × 0.6 + frequency × 0.3 + platform_hot_value × 0.1) rather than simple ranking
vs alternatives: Covers more Chinese platforms than generic news aggregators (Feedly, Inoreader) and uses weighted composite scoring instead of single-metric ranking, making it superior for investors tracking multi-platform sentiment
Filters aggregated news against user-defined keyword lists (frequency_words.txt) using regex pattern matching and boolean logic (required keywords AND, excluded keywords NOT). Implements a scoring engine that weights matches by keyword frequency tier and calculates relevance scores. Supports regex patterns, case-insensitive matching, and multi-language keyword sets. Articles matching filter criteria are retained; non-matching articles are discarded before analysis and notification stages.
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 alternatives: 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
TrendRadar scores higher at 51/100 vs enhanced-postgres-mcp-server at 29/100.
