Abstract

A method and apparatus for generating search results with higher relevancy. The present invention exploits the fact that users'"'"' choices on each given search term tend to converge to several products from several merchants, and all of the results are very relevant to the search term. In one embodiment, these results are used to decide the order of merchants for each search term. By learning the users'"'"' choices, especially from purchasing and/or clicking information, highly relevant and most popular products can be assigned a higher score or rank over text relevant only products.

Claims

1-98. -98. (canceled)

99. A search engine method, comprising:

gathering click information associated with a member of a search result set having a plurality of members, the search result set produced in response to a search;

determining relative responsiveness of the member, compared with the other members of the search result set, based on the click information, and on a position of the member in an ordering for display of the search result set;

generating a score for association with the item that reflects the relative responsiveness of the item to the search; and

using the score to affect a response to a subsequent search.

100. The method of claim 99, wherein said score is applied to affect placement of said member within the ordering of said search result set.

101. The method of claim 99, further comprising adjusting said score to account for passage of time.

102. The method of claim 99, further comprising adjusting said score to account for a specific knowledge of said member.

103. The method of claim 99, further comprising adjusting said score to account for a specific knowledge of a search term used in the search.

104. The method of claim 99, further comprising applying said score in conjunction with a text relevancy score, a paid inclusion score, or a paid sponsorship score.

105. The method of claim 99, wherein said member is a product page.

106. The method of claim 99, wherein said member is a catalog page.

107. The method of claim 106, wherein said catalog page represents a display page for a product that displays a plurality of merchants who are offering said product.

108. The method of claim 107, wherein said catalog page also displays pricing information for said product by said plurality of merchants.

109. The method of claim 99, wherein said generating generates a score for said member based on a type of click in the click information.

110. The method of claim 99, wherein the click information comprises clicks categorizable as a preferred merchant click type that represents clicks made with a preferred merchant.

111. The method of claim 99, wherein the click information comprises clicks of a mapped catalog click type for clicks on a product page associated with a catalog page.

112. The method of claim 99, further comprising applying a usage function to said score.

113. The method of claim 99, further comprising selecting a configuration for generating the score.

114. The method of claim 113, further comprising computing a parameter defined in the configuration, and wherein said score is generated in accordance with said configuration parameter and a click type.

115. The method of claim 99, wherein the score is generated in accordance with:

Hotscore_k,p=Σ

(α

_k,t,T(t)C_k,p,t)

where C_k,p,t is a number of clicks in at least one click type t for a search term k used in the search that returned member p, and α

_k,t,T(t) is a configuration parameter.

116. The method of claim 99, wherein generating the score comprises selecting a formula emphasizing a scoring strategy from a plurality of formulas, each of the plurality emphasizing a different scoring strategy.

117. A computer readable medium comprising instructions for a method of gathering click information associated with a member of a search result set having a plurality of members, the search result set produced in response to a search;

determining relative responsiveness of the member, compared with the other members of the search result set, based on the click information, and on a position of the member in an ordering for display of the search result set;

generating a score for association with the item that reflects the relative responsiveness of the item to the search; and

using the score to affect a response to a subsequent search.

118. The computer readable medium of claim 117, wherein generating the score comprises selecting a formula emphasizing a scoring strategy from a plurality of formulas, each of the plurality emphasizing a different scoring strategy.

119. The computer readable medium of claim 117, wherein the method further comprises selecting a configuration for generating the score.

120. The computer readable medium of claim 117, wherein said score is applied to affect placement of the member within the ordering of said search result set.

121. The computer readable medium of claim 117, further comprising adjusting said score to account for passage of time.

122. The computer readable medium of claim 117, further comprising adjusting said score to account for a specific knowledge of said member.

123. The computer readable medium of claim 117, wherein the method further comprises adjusting the score to account for a specific knowledge of a search term used in the search.

124. The computer readable medium of claim 117, wherein the method further comprises applying the score in conjunction with a text relevancy score, a paid inclusion score, or a paid sponsorship score.
