Social Behavior Analysis And Inferring Social Networks For A Recommendation System

View page
US Patent:
8073794, Dec 6, 2011
Filed:
Dec 20, 2007
Appl. No.:
11/961555
Inventors:
Sihem Amer-Yahia - New York NY, US
Evgeniy Gabrilovich - Sunnyvale CA, US
Bo Pang - Sunnyvale CA, US
Julia Stoyanovich - New York NY, US
Cong Yu - New York NY, US
Assignee:
YAHOO! Inc. - Sunnyvale CA
International Classification:
G06F 17/00
G06N 5/00
US Classification:
706 45
Abstract:
Systems and methods are provided for determining items or people of potential interest to recommend to users in a computer-based network. Implied social networks may be determined based at least in part on obtained social behavior information. Items or people of potential interest to users may be determined based at least in part on implied social network information. Vocabulary taxonomies may be associated with, or used in determining, implied social networks.

Automatically And Adaptively Determining Execution Plans For Queries With Parameter Markers

US Patent:
20080195577, Aug 14, 2008
Filed:
Feb 9, 2007
Appl. No.:
11/673091
Inventors:
Wei Fan - New York NY, US
Guy Maring Lohman - San Jose CA, US
Volker Gerhard Markl - San Jose CA, US
Nimrod Megiddo - Palo Alto CA, US
Jun Rao - San Jose CA, US
David Everett Simmen - San Jose CA, US
Julia Stoyanovich - New York NY, US
International Classification:
G06F 17/30
US Classification:
707 2, 707E17017
Abstract:
A method for automatically and adaptively determining query execution plans for parametric queries. A first classifier trained by an initial set of training points is generated using a set of random decision trees (RDTs). A query workload and/or database statistics are dynamically updated. A new set of training points collected off-line is used to modify the first classifier into a second classifier. A database query is received at a runtime subsequent to the off line phase. The query includes predicates having parameter markers bound to actual values. The predicates are associated with selectivities. The query execution plan is determined by identifying an optimal average of posterior probabilities obtained across a set of RDTs and mapping the selectivities to a plan. The determined query execution plan is included in an augmented set of training points that includes the initial set and the new set.

International Classification:
G06F 17/30
US Classification:
707 2, 707E17131
Abstract:
A method and system for automatically and adaptively determining query execution plans for parametric queries. A first classifier trained by an initial set of training points is generated. A query workload and/or database statistics are dynamically updated. A new set of training points is collected off-line. Using the new set of training points, the first classifier is modified into a second classifier. A database query is received at a runtime subsequent to the off-line phase. The query includes predicates having parameter markers bound to actual values. The predicates are associated with selectivities. A mapping of the selectivities into a plan determines the query execution plan. The determined query execution plan is included in an augmented set of training points, where the augmented set includes the initial set and the new set.
