Patent number: 8285721Abstract: An item record in an item database contains an item description generated by a seller of an item. A server machine is configured to access the item database, analyze the item description, and extract descriptive information by inferring an attribute and a corresponding attribute value from the item description. The attribute and its attribute value constitute an attribute-value pair. The server machine uses the attribute-value pair to map the item record to a product record stored in a product database. The mapping of the item record to the product record is based on comparing the attribute-value pair of the item record to a reference attribute-value pair in the product record to identify the product record. The mapping is performed upon detection of a match between the attribute-value pairs.Type: GrantFiled: September 28, 2009Date of Patent: October 9, 2012Assignee: eBay Inc.Inventors: Jean-David Ruvini, Badrul M. Sarwar, Neelakantan Sundaresan

Patent number: 8145638Abstract: A method and a system to organize a data set into groups of data subsets in multiple passes using different parameters and to automatically name the groups is disclosed. For example, a data set is retrieved in accordance with a search query submitted by a user. The data set is organized into clusters based on a statistic(s) of the data set. The data set is then organized into groups of data subsets based on an attribute(s) indicated by the data set. Each of the groups are automatically named based on a property shared by data units of the group. The name(s) of a group may be mined from the data units of the group, retrieved from a structure that maps to attribute values indicated by the data units of the group, etc.Type: GrantFiled: March 14, 2011Date of Patent: March 27, 2012Assignee: eBay Inc.Inventors: John A. Mount, Badrul M. Sarwar

Publication number: 20120041831Abstract: A method and a system are described for catalog generation based on divergent listings. For example, a listing module may receive a divergent listing and collect data corresponding to an item in the listing. Each divergent listing of an item for sale is divergent with respect to other listings of the same item for sale. A calculation module may calculate an entropy value based on the collected data, the entropy value indicating a degree of difference between the item in the listing and a product in a catalog. A catalog module may associate the listing to the product in the catalog based on the entropy value.Type: ApplicationFiled: October 31, 2011Publication date: February 16, 2012Inventors: Jean-David Ruvini, Neelakantan Sundaresan, Badrul M.

Publication number: 20100042511Abstract: There is provided a method and system for qualification testing in a social network service. Qualification testing provides access control into a social network, wherein qualification is based on answers to questions related to a topic. In one example, members admitted to the network provide guidance, notes and research assistance to another member. The social network members access the social network from an external networked computing service, such as another social network, to facilitate easy connection to potential members. The social network may be implemented as an application overlay to the external service, or may access connections in the external network.Type: ApplicationFiled: March 5, 2009Publication date: February 18, 2010Inventors: Neelakantan Sundaresan, Vasilios Mitrokostas, Lauren Olver, Chi-Hsien Chiu, Jean-David Ruvini, Badrul M.
