# Deep Research Tool Quality Metrics This document outlines the quality metrics collection for the Deep Research tool, which gathers anonymous usage data to improve search result quality and performance. ## About Quality Metrics The Deep Research tool includes built-in metrics collection that helps us: - Improve search result quality - Optimize performance - Identify and fix issues - Enhance the user experience All data collection is anonymous and focused on improving the tool's functionality. ## Configuration (Optional) The quality metrics system works out-of-the-box with no setup required. However, if you wish to use your own PostHog instance for analytics, you can customize the configuration: ```bash # Optional configuration for custom analytics USAGE_METRICS_KEY=your-posthog-key-here USAGE_PROJECT_ID=your-project-id-here METRICS_ENDPOINT=https://your-posthog-instance.com ``` To disable metrics collection entirely (not recommended as it helps improve the tool): ```bash # Not recommended DISABLE_METRICS=true ``` ## Collected Metrics ### Research Process Metrics 1. `operation.started` - Query text and length - Research depth level - Maximum sources requested - Timestamp 2. `research.query_analyzed` - Query complexity score - Topic category - Estimated completion time 3. `research.subqueries_generated` - Number of sub-queries - Sub-query topics - Generation time 4. `research.search_executed` - Sub-query text - Number of results found - Search execution time 5. `research.sources_processed` - Total sources found - Number of unique domains - Average relevance score 6. `research.synthesis_completed` - Final source count - Synthesis processing time - Result length - Number of citations 7. `research.completed` - Total searches performed - Total sub-queries used - Research depth - Success status - Total research time 8. `operation.issue` - Processing stage - Issue type - Issue details - Query information ## Analytics Dashboard Examples ### Research Usage Dashboard 1. Research Volume ```sql SELECT count(*) as research_count, properties.$time as time FROM events WHERE event = 'research.started' GROUP BY time ``` 2. Depth Level Distribution ```sql SELECT properties.depth as depth, count(*) as count FROM events WHERE event = 'research.started' GROUP BY depth ``` 3. Average Research Time ```sql SELECT properties.depth as depth, avg(properties.totalTime) as avg_time FROM events WHERE event = 'research.completed' GROUP BY depth ``` ### Performance Metrics Dashboard 1. Search Performance ```sql SELECT avg(properties.searchTime) as avg_search_time, avg(properties.resultsCount) as avg_results FROM events WHERE event = 'research.search_executed' ``` 2. Sub-query Generation ```sql SELECT avg(properties.count) as avg_subqueries, avg(properties.generationTime) as avg_generation_time FROM events WHERE event = 'research.subqueries_generated' ``` 3. Synthesis Performance ```sql SELECT avg(properties.synthesisTime) as avg_synthesis_time, avg(properties.citationCount) as avg_citations FROM events WHERE event = 'research.synthesis_completed' ``` ### Error Analysis Dashboard 1. Error Rate by Stage ```sql SELECT properties.stage as stage, count(*) as error_count FROM events WHERE event = 'research.error' GROUP BY stage ``` 2. Common Error Types ```sql SELECT properties.errorType as error_type, count(*) as count FROM events WHERE event = 'research.error' GROUP BY error_type ORDER BY count DESC LIMIT 10 ``` ### Source Quality Dashboard 1. Domain Distribution ```sql SELECT properties.uniqueDomains as domains, avg(properties.averageRelevanceScore) as avg_relevance FROM events WHERE event = 'research.sources_processed' GROUP BY domains ``` 2. Citation Analysis ```sql SELECT properties.depth as depth, avg(properties.citationCount) as avg_citations FROM events WHERE event = 'research.synthesis_completed' GROUP BY depth ``` ## Key Performance Indicators 1. Research Efficiency - Track average completion time by depth level - Monitor sub-query generation efficiency - Analyze search result quality 2. Error Patterns - Identify common failure points - Track error rates by research stage - Monitor query characteristics leading to errors 3. Usage Patterns - Analyze popular query types - Track depth level preferences - Monitor source citation patterns 4. Quality Metrics - Track source diversity - Monitor citation counts - Analyze relevance scores ## Continuous Improvement Process 1. Quality Monitoring - Regular dashboard review - Issue detection and resolution - Performance optimization 2. Search Enhancement - Query decomposition refinement - Search strategy optimization - Depth parameter calibration 3. Resource Management - Response time optimization - Throughput improvement - Rate limiting refinement 4. Research Quality - Source evaluation enhancement - Relevance calculation refinement - Citation quality improvement
