The broader categorization of a piece of content into general domains (e.g., medicine, sports), establishing an overarching understanding of the general topic.
Macro-context is the broader categorization of content or a query into general domains (e.g., medicine, sports, technology), establishing an overarching understanding of the primary subject matter. When a query is received, the search system first determines its macro-context to understand the high-level topic, allowing it to filter out irrelevant areas from the start and assign a high-level topic relevance score. This concept is similar to the primary categories found in text classification APIs (e.g., news, health, business).
