Extracts named entities, relationships, and attributes from documents using LLM-based prompting with configurable extraction schemas. The system uses a workflow-based pipeline architecture that chains LLM calls through a task execution engine, supporting multiple LLM providers (OpenAI, Azure OpenAI, Anthropic, Ollama) with built-in rate limiting, retry strategies, and token-aware batching. Extracted entities and relationships are structured into a knowledge graph schema with configurable entity types, relationship types, and attributes.
Unique: Uses a modular workflow system with pluggable LLM providers and configurable extraction schemas, enabling domain-specific entity/relationship definitions without code changes. Implements provider-agnostic rate limiting and retry logic at the LLM integration layer, allowing seamless switching between OpenAI, Azure, Anthropic, and local Ollama without pipeline modifications.
vs alternatives: More flexible and provider-agnostic than LangChain's extraction chains, and more structured than simple prompt-based extraction, with built-in support for multi-provider failover and domain-specific schema customization.
Detects communities (clusters of densely-connected entities) within the extracted knowledge graph using graph algorithms, then organizes them hierarchically into levels for multi-scale analysis. The system applies community detection algorithms to partition the graph, generates summaries for each community at each hierarchy level, and stores these as 'community reports' that serve as intermediate representations for query-time reasoning. This enables both local (entity-neighborhood) and global (community-level) search strategies.
Unique: Combines graph-based community detection with LLM-generated hierarchical summaries, creating intermediate representations that enable both local and global search strategies without full-graph traversal. Stores community reports as first-class artifacts in the knowledge graph, enabling query-time selection of appropriate abstraction levels.
vs alternatives: More sophisticated than flat entity clustering, and more efficient than naive full-graph traversal at query time. Hierarchical structure enables adaptive reasoning that can zoom between local detail and global context, unlike single-level clustering approaches.
Constructs LLM prompts by combining retrieved context (entities, relationships, community reports) with query information and response instructions. The system extracts entities from queries, retrieves relevant context from the knowledge graph, ranks context by relevance, and assembles prompts that include both structured context (entity descriptions, relationships) and unstructured context (text chunks). Context building strategies differ between Global Search (community-level context), Local Search (entity-neighborhood context), and DRIFT Search (combined context).
Unique: Combines structured context (entities, relationships, community reports) with unstructured context (text chunks) in a single prompt, with strategy-specific context builders for Global, Local, and DRIFT search. Ranks context by relevance and enforces token limits.
vs alternatives: More sophisticated than simple context concatenation, with strategy-specific context building and relevance ranking. Combines multiple context types (structured and unstructured) for richer prompts than single-type approaches.
Implements provider-agnostic rate limiting, exponential backoff retry logic, and fault tolerance mechanisms for LLM API calls. The system tracks token usage and API call rates, enforces per-provider rate limits, retries failed calls with exponential backoff, and handles transient failures gracefully. This enables reliable indexing and querying even with unreliable network conditions or rate-limited APIs. Rate limiting is configurable per provider and per operation type.
Unique: Implements provider-agnostic rate limiting and retry logic that works across OpenAI, Azure OpenAI, Anthropic, and Ollama without provider-specific code. Configurable per-provider rate limits and retry strategies enable optimization for different providers.
vs alternatives: More sophisticated than naive retry logic, with provider-aware rate limiting and exponential backoff. Enables reliable large-scale indexing without manual rate limit management.
Provides a command-line interface for all major GraphRAG operations: initializing new indexes, running indexing pipelines, executing queries, tuning prompts, and updating existing indexes. The CLI supports both interactive and batch modes, with progress reporting, error handling, and result formatting. Commands are organized hierarchically (e.g., 'graphrag index', 'graphrag query', 'graphrag prompt-tune') and support configuration file overrides through command-line arguments.
Unique: Provides a comprehensive CLI covering all major GraphRAG operations (indexing, querying, prompt tuning, updates) with configuration file support and command-line overrides. Enables both interactive and batch workflows without Python code.
vs alternatives: More user-friendly than programmatic API for simple operations, and more flexible than web UI for automation. CLI-based approach enables integration with shell scripts, CI/CD pipelines, and other command-line tools.
Implements multi-level caching to reduce redundant LLM API calls and embedding computations. The system caches LLM responses by prompt hash, caches embeddings by text hash, and supports both in-memory and persistent (file-based or database) caching. Cache hits avoid expensive API calls, significantly reducing indexing time and cost for repeated operations. Cache invalidation is based on content hashing, enabling safe cache reuse across runs.
Unique: Implements multi-level caching (in-memory and persistent) for both LLM calls and embeddings, with content-based cache invalidation. Enables significant cost and time savings for large-scale indexing and iterative development.
vs alternatives: More comprehensive than single-level caching, with support for both LLM responses and embeddings. Persistent caching enables cache reuse across runs, unlike in-memory-only approaches.
Implements three distinct search strategies that can be selected or combined at query time: (1) Global Search uses community reports and hierarchical summaries for high-level reasoning over the entire dataset, (2) Local Search retrieves entity neighborhoods and relationships for detailed reasoning about specific entities, and (3) DRIFT Search (Dynamic Retrieval In-context Fusion Technique) combines both strategies with adaptive context selection. Each strategy uses vector embeddings for semantic matching, entity extraction from queries, and context building to construct LLM prompts with relevant information.
Unique: Implements three distinct search strategies (Global, Local, DRIFT) that operate at different abstraction levels of the knowledge graph, enabling adaptive retrieval based on query characteristics. DRIFT Search combines strategies with in-context fusion, allowing the LLM to reason over both community-level summaries and entity-level details in a single response.
vs alternatives: More sophisticated than single-strategy RAG systems (e.g., basic vector similarity search), offering both breadth (global) and depth (local) reasoning. DRIFT Search's adaptive combination of strategies outperforms fixed-strategy approaches on diverse query types.
Provides a modular, configuration-driven indexing pipeline that orchestrates document loading, chunking, entity/relationship extraction, community detection, embedding generation, and graph finalization. The system uses a factory pattern for LLM providers (OpenAI, Azure OpenAI, Anthropic, Ollama), vector stores (LanceDB, Azure AI Search, Cosmos DB), and storage backends (local file system, Azure Blob Storage, in-memory). Configuration is managed through YAML files with environment variable overrides, enabling environment-specific setup without code changes.
Unique: Uses factory pattern and dependency injection to abstract away provider-specific implementations, allowing seamless swapping of LLM providers, vector stores, and storage backends through configuration alone. Configuration-first design enables version-controlled, reproducible indexing without code changes.
vs alternatives: More flexible than hardcoded RAG pipelines, and more provider-agnostic than frameworks tightly coupled to specific LLM APIs. Configuration-driven approach enables non-technical users to customize pipelines without code modifications.

Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs graphrag at 38/100.

vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
