Source Evaluation

Overview

Evaluate reliability and timeliness of information sources; filter low-quality content.

Source Authority Scoring

• Domain reputation: Known authoritative domains (e.g., official docs, .gov, .edu)
• Publisher track record: Historical accuracy; user ratings if available
• Expertise signals: Author credentials, institutional affiliation

Freshness Assessment

• Extract publication/update date from page metadata or content
• Score by recency; deprioritize stale content for time-sensitive topics
• Handle missing dates; infer from context when possible

Bias Detection

• Identify promotional, opinion, or advocacy content vs factual
• Flag potential conflicts of interest (e.g., vendor-authored comparisons)
• Surface bias level to user; do not auto-filter, allow user choice

Cross-Reference Verification

• Check if claims are corroborated by multiple independent sources
• Weight corroboration in overall score

Citation Tracking

• Track which sources cite which; build citation graph
• Prefer well-cited sources; flag uncited or circular citations
