Changing ranking algorithms based on customer settings
First Claim
1. A method for ranking search results using user preferences, the method comprising:
- obtaining a set of custom ranking factors which specify document attributes to be applied to search results for a query;
for each of the custom ranking factors, defining a type of the custom ranking factor;
receiving a user-supplied weight from a user for each of the set of custom ranking factors which specify document attributes;
generating, using a processor operatively coupled to a memory, a ranking algorithm that is a combination function of the set of custom ranking factors which specify document attributes based on the user-supplied weights for the ranking factors and the type of the custom ranking factors;
applying the ranking algorithm to search results for the query; and
displaying the search results ranked according to the ranking algorithm.

Abstract
Search term ranking algorithms can be generated and updated based on customer settings, such as where a ranking algorithm is modeled as a combination function of different ranking factors. An end user of a search system provides personalized preferences for weighted attributes, generally or for a single instance of the query. The user also can indicate the relative importance of one or more ranking factors by specifying different weights to the factors. Ranking factors can specify document attributes, such as document title, document body, document page rank, etc. Based on the attribute weights and the received user query, a ranking algorithm function will produce the relevant value for each document corresponding to the user preferences and personalization configurations.

12. A non-transitory computer-readable medium for ranking search results using user preferences having sets of instructions stored thereon which, when executed by a computer, cause the computer to:
-
obtain a set of custom ranking factors which specify document attributes to be applied to search results for a query; for each of the custom ranking factors, define a type of the custom ranking factor; receive a user-supplied weight from a user for each of the set of custom ranking factors which specify document attributes; generate a ranking algorithm that is a combination function of the set of custom ranking factors which specify document attributes based on the user-supplied weights for the ranking factors and the type of the custom ranking factors; apply the ranking algorithm to search results for the query; and display the search results ranked according to the ranking algorithm. - View Dependent Claims (13, 14, 15, 16)

17. A system for ranking search results using user preferences, the system comprising:
-
a storage medium; and a processor coupled to the storage medium, wherein the storage medium includes sets of instructions which, when executed by the processor, cause the processor to; obtain a set of custom ranking factors which specify document attributes to be applied to search results for a query, for each of the custom ranking factors, define a type of the custom ranking factor, receive a user-supplied weight from a user for each of the set of custom ranking factors which specify document attributes, generate a ranking algorithm that is a combination function of the set of custom ranking factors which specify document attributes based on the user-supplied weights for the ranking factors and the type of the custom ranking factors, apply the ranking algorithm to search results for the query, and display the search results ranked according to the ranking algorithm. - View Dependent Claims (18, 19, 20)
