Get keywords extraction insights

This article explains how to get keywords extraction insights from Azure AI Video Indexer (VI). Keywords extraction finds important keywords in media files and provides insights in both single-language and multi-language media files.

Keywords extraction use cases

• Personalization of keywords to match customer interests. For example, websites about England posting promotions about English movies or festivals.
• Deep-searching archives for insights on specific keywords to create feature stories about companies, personas, or technologies, for example by a news agency.
