Generating related questions for search queries
Topics: Ranking, SERP Serving (Tangram/Glue), SERP-Features, User Signals
This Google patent describes a method for generating related questions for search queries. The system receives a search query, obtains search results, selects topic queries for each search result resource based on previous user interactions, and then selects related questions from a question database that match those topic queries. The related questions are then sent back to the user along with the search results. Key aspects include using previous user behavior to identify relevant topic queries, filtering out duplicate/equivalent questions, and ranking the questions before presenting them to the user. This approach aims to provide users with additional relevant questions to help them explore a topic or refine their search.
