GENERATING DOMAIN-BASED TRAINING DATA FOR TAIL QUERIES

摘要

Training data is provided for tail queries based on a phenomena in search engine user behavior—referred to herein as domain trust—as an indication of user preferences for individual URLs in search results returned by a search engine for tail queries. Also disclosed are methods for generating training data in a search engine by forming a collection of query+URL pairs, identifying domains in the collection, and labeling each domain. Other implementations are directed ranking search results generated by a search engine by measuring domain trust for each domain corresponding to each URL from among a plurality of URLs and then ranking each URL by its measured domain trust.
