YandexOntoDB is a Yandex crawler used to extract and analyze structured knowledge from webpages for Yandex’s ontology and knowledge graph systems. It processes content to detect entities, relationships, attributes, and semantic patterns. This crawler supports Yandex’s understanding of people, organizations, places, and concepts across the web rather than performing standard search indexing. Crawl activity is typically focused and analytical, targeting pages rich in factual or structured information that can enhance Yandex’s internal knowledge databases. YandexOntoDB bot honors the global robots.txt user agent (*) rule. RobotSense.io verifies YandexOntoDB using Yandex’s official validation methods, ensuring only genuine YandexOntoDB traffic is identified.

This bot does not honor Crawl-Delay rule.
