Abstract: A method and an apparatus of identifying a user feature include: in response to receiving a designated evaluation of an interacting party in a service interaction, determining a reliability value of the designated evaluation of the interacting party based on a feature value of the service interaction; based on reliability values of multiple designated evaluations of the interacting party in multiple service interactions including the designated evaluation, determining a reliability mean value of the multiple designated evaluations; determining a reliability weighted mean value of the multiple designated evaluations based on a frequency weight corresponding to the multiple designated evaluations and the reliability mean value, wherein a number of the multiple designated evaluations is in a monotonically incremental or decremental relationship with the corresponding frequency weight; determining a user feature of the interacting party based on a size relationship between the reliability weighted mean value and

Abstract: Providing a query results page is disclosed, including by: receiving a current query; determining a correction factor corresponding to the current query; determining a corrected query results request quantity based at least in part on the correction factor; performing an initial search for a plurality of query results responsive to the current query, wherein a quantity of query results included in the plurality of query results corresponds to the corrected query results request quantity; determining a quantity of compliant query results of the plurality of query results by comparing at least some of the plurality of query results to one or more display conditions and identifying compliant query results that meet the one or more display conditions; and causing a page of query results to be presented based at least in part on the quantity of compliant query results.

Abstract: Embodiments of the present application relate to a method for testing multiple versions, a device for testing multiple versions, and a computer program product for testing multiple versions. A method for testing multiple versions is provided. The method includes acquiring diversion tag values of users visiting a current product, the diversion tag values uniquely identifying the corresponding users, calculating diversion hashed values of the diversion tag values, and allocating an old version and a new version of the current product to the users according to a preset old version or new version allocation ratio for the current product and the diversion hashed values to test multiple versions of the current product.
