Patent number: 10546027Abstract: Disclosed are various embodiments for performing data search queries for descriptive semantics extracted from item reviews. Search queries that resulted in a selection of a browse node of an item taxonomy are identified and various items associated with the browse node are determined. Customer reviews for the various items are used to phrases used in the customer reviews that also appear in the search queries. The phrases may be ranked based at least in part on a polarity metric that describes a subjectivity, sentiment, and/or coverage of the phrase. Phrases with a rank exceeding a predefined threshold may be made available for use by a search component of a network site.Type: GrantFiled: June 9, 2015Date of Patent: January 28, 2020Assignee: Amazon Technologies, Inc.Inventors: Gabriel Parent, Debprakash Patnaik, Amanda Dee Bottorff, Matthew McDonald Furlong

Patent number: 10235449Abstract: Disclosed is a platform for assessing queries related to a catalog entry. The platform is able to determine what attributes of the catalog entry the query is directed to using one or more language processing techniques. Once an attribute is identified, the platform may check for appropriate unit types and/or formats based on a category associated with the attribute. The platform then parses additional data associated with the catalog entry (or another catalog entry within the same browse node) to identify a set of potential values for the identified attribute. One or more rule sets may be used to filter the set of potential values to a single probable value, which may then be provided in a response to the query.Type: GrantFiled: September 25, 2015Date of Patent: March 19, 2019Assignee: Amazon Technologies, Inc.Inventors: Krishnamurthy Koduvayur Viswanathan, Debprakash Patnaik

Patent number: 10102195Abstract: Systems and methods involve filling missing attribute values from unstructured text. A computing device may provide a plurality of items, such as an item catalog for an electronic marketplace. When an item is found to have a missing attribute value, a plurality of existing values for that attribute is compiled by mining other items. Text associated with the item is parsed to determine possible values for the attribute. From those possible values, the most likely value is identified and the missing attribute value is populated with that value.Type: GrantFiled: June 25, 2014Date of Patent: October 16, 2018Assignee: Amazon Technologies, Inc.Inventors: Jianhui Wu, Taibai Xu, Wenke Zhang, Rongzhou Shen, Krishnamurthy Koduvayur Viswanathan, Gabriel Parent, Jiwei Cao, Debprakash Patnaik

Patent number: 9959563Abstract: Systems and methods are disclosed for generating recommendation rules based on the attributes of items that are purchased together at a threshold rate. The attributes of the items may be extracted from item-detail content associated with the items. Using a count of the frequency with which pairs of items include pairs of attributes, a recommendation rule can be created that recommends items with particular attributes to users who access other items with particular attributes. Further, using the recommendation rules, items may be selected for recommendation to users who access an item that lacks historical access data from which to generate recommendations solving the “cold-start” problem. Moreover, negative rules may be generated based on historical access data and attributes of items purchased and/or not purchased together at a threshold rate to prevent the recommendation of particular items to users who access items associated with the negative rules.Type: GrantFiled: December 19, 2013Date of Patent: May 1, 2018Assignee: Amazon Technologies, Inc.Inventors: Jianhui Wu, Debprakash Patnaik, Rui Wang

Patent number: 8832012Abstract: Tree discovery systems and methods are disclosed. An example of a method is carried out by program code stored on non-transient computer-readable medium and executed by a processor. The method may include identifying in computer-readable medium a first node for a system under consideration, each node in the computer-readable medium representing a characteristic of a component. The method may include selecting at least a second node from the computer-readable medium for the first node. The method may include discovering in the computer-readable medium at least one system tree for the system under consideration based on the first node and the at least second node.Type: GrantFiled: October 26, 2011Date of Patent: September 9, 2014Assignee: Hewlett-Packard Development Company, L. P.Inventors: Naren Sundaravaradan, Debprakash Patnaik, Manish Marwah, Amip Shah, Naren Ramakrishnan

Patent number: 8170743Abstract: An integrated diagnosis and prognosis system that collects vehicle information over the life of a vehicle and its development. The system provides the collected vehicle information to supplier management, product development management, service/dealership management, customer relations departments and production facilities, which use the information to take certain action for existing vehicles, fleets of vehicles or future vehicles to improve vehicle reliability and quality.Type: GrantFiled: January 29, 2009Date of Patent: May 1, 2012Assignee: GM Global Technology Operations LLCInventors: Mutasim A.

Patent number: 8095261Abstract: A system and method for enhancing vehicle diagnostic and prognostic algorithms and improving vehicle maintenance practices. The method includes collecting data from vehicle components, sub-systems and systems, and storing the collected data in a database. The collected and stored data can be from multiple sources for similar vehicles or similar components and can include various types of trouble codes and labor codes as well as other information, such as operational data and physics of failure data, which are fused together. The method generates classes for different vehicle components, sub-systems and systems, and builds feature extractors for each class using data mining techniques of the data stored in the database. The method also generates classifiers that classify the features for each class. The feature extractors and feature classifiers are used to determine when a fault condition has occurred for a vehicle component, sub-system or system.Type: GrantFiled: March 5, 2009Date of Patent: January 10, 2012Assignee: GM Global Technology Operations LLCInventors: Mark N.
