Patent number: 10915557Abstract: Computerized data processing and electronic file management methods of organizing and indexing electronic records in an electronic database for categorizing new products that are being added to an existing database of product offerings and computerized digital data processing methods of transferring digital information between a plurality of computers and employing computer instructions to categorize new products that are being added to an existing database of product offerings. Multiple classification models classify a description of a particular product and the classifications are compared, and if found to be equivalent, are added to the existing database of product offerings. If the classifications from the models are not equivalent, then the description is sent to multiple people for classification and the classifications from the people are compared, and if found to be equivalent, are added to the existing database of product offerings.Type: GrantFiled: September 8, 2015Date of Patent: February 9, 2021Assignee: WALMART APOLLO, LLCInventors: Nikesh Lucky Garera, Narasimhan Rampalli, Dintyala Venkata Subrahmanya Ravikant, Srikanth Subramaniam, Chong Sun, Heather Dawn Yalin

Patent number: 10169798Abstract: A method of computing a featured set of product groups for a query on an inventory of products. Each of the products can have one or more attribute-value pairs. Each of the one or more attribute-value pairs can have an attribute. The method can include determining a result group of the products matching the query. The method also can include determining relevance scores for the product groups. The method further can include determining a featured attribute and the featured set of the product groups for the featured attribute. The method also can include, after receiving the query from a user, transmitting for display at least one page of a website, where the at least one page has an option to view each of the product groups of the featured set of the product groups that has been selected. Other embodiments of related systems and methods are also disclosed.Type: GrantFiled: June 3, 2014Date of Patent: January 1, 2019Assignee: WALMART APOLLO, LLCInventors: Dintyala Venkata Subrahmanya Ravikant, Abhishek Gattani

Patent number: 9390378Abstract: Systems and methods are disclosed herein for classifying records, such as product records, using a machine learning algorithm. After training a classification model according to a machine learning algorithm using an initial training set, records are classified and high confidence classifications identified. Remaining classifications are submitted to a crowdsourcing forum that validates or invalidates the classifications or marks them as to unclear to evaluate. Invalidated classifications are automatically analyzed to identify one or both of classification values and categories having a high proportion of invalidated classifications. Requests are transmitted to analysts to generate training data that is added to the training set. The process of classifying records and obtaining crowdsourced validation thereof may then repeat.Type: GrantFiled: March 28, 2013Date of Patent: July 12, 2016Assignee: Wal-Mart Stores, Inc.Inventors: Nikesh Lucky Garera, Narasimhan Rampalli, Dintyala Venkata Subrahmanya Ravikant, Srikanth Subramaniam, Chong Sun, Heather Dawn Yalin

Patent number: 9348902Abstract: Systems and methods are disclosed herein for performing classification of documents or performing other tasks based on rules. The rules may include context rules that define a mapping that relates a value and context in a document to an attribute to which the value corresponds. Products are selected for labeling with attributes by identifying patterns, e.g. values and contexts that are not covered by a current rule set. Those products having a highest score are selected for labeling in a crowd sourcing forum, where the score is based on the number of non-covered patterns and a frequency of occurrence of the non-covered patterns in a document corpus. Proposed rules are generated for frequently occurring patterns and submitted to analysts for one or both of completion and validation. Proposed rules may include a proposed attribute for a frequently occurring value and corresponding context.Type: GrantFiled: January 30, 2013Date of Patent: May 24, 2016Assignee: Wal-Mart Stores, Inc.Inventors: Nikesh Lucky Garera, Narasimhan Rampalli, Dintyala Venkata Subrahmanya Ravikant, Srikanth Subramaniam, Chong Sun, Heather Dawn Yalin

Patent number: 9311372Abstract: Systems and methods are disclosed herein for generating a normalized record from an import record, the normalized record having attribute-value pairs corresponding to a native schema. In import records, a plurality of attribute-value are identified each having an attribute label not found in a native schema. One or more attribute labels in the native schema having as possible values one or more values corresponding to the values of the plurality of attribute-value pairs are also identified. The computer system generates one or more normalization rules relating one or more attribute labels of the plurality of attribute-value pairs to at least a portion of the one or more attribute labels in the native schema. Normalization rules may be validated by crowdsourcing. Normalization rules may be applied by identifying implicated rules by classifying the import record and identifying rules applicable to the classification.Type: GrantFiled: May 31, 2013Date of Patent: April 12, 2016Assignee: Wal-Mart Stores, Inc.Inventors: Nikesh Lucky Garera, Narasimhan Rampalli, Dintyala Venkata Subrahmanya Ravikant, Srikanth Subramaniam, Chong Sun, Heather Dawn Yalin

Patent number: 9208442Abstract: Systems and methods are disclosed herein for obtaining a structured listing of attributes and corresponding values based on an unstructured document, such as a product description in a product record. Putative values are identified in the document and corresponding candidate attributes are identified in a taxonomy. Attribute-value pairs are then evaluated with respect to a plurality of rules. Attribute-value pairs and outputs of the one or more rules are evaluated using a machine-learning algorithm, such as a decision tree, in order to determine which attribute-value pairs to retain. Retained attribute-value pairs are stored and used to respond to search queries and facilitate comparison of products. Attributes selected may also be used to update a product template.Type: GrantFiled: April 26, 2013Date of Patent: December 8, 2015Assignee: Wal-Mart Stores, Inc.Inventors: Nikesh Lucky Garera, Narasimhan Rampalli, Dintyala Venkata Subrahmanya Ravikant, Srikanth Subramaniam, Chong Sun, Heather Dawn Yalin
