Methods and systems for selecting an optimized scoring function for use in ranking item listings presented in search results

摘要: Methods and systems for simulating a search, the purpose of evaluating one or more scoring functions used in ordering item listings presentation search results page are described. Consistent with some embodiments, simulation platform includes real-time module that receives result sets queries conclusion transaction. The set is then processed by test functions, such resulting position listing has resulted transaction can be compared actual at which was displayed results. For each function, an average rank shift metric determined, displayed, thereby providing to base decisions about use production system.
