Patent number: 11900274Abstract: Disclosed systems, methods, and computer readable media can detect an association between semantic entities and generate semantic information between entities. For example, semantic entities and associated semantic collections present in knowledge bases can be identified. A time period can be determined and divided into time slices. For each time slice, word embeddings for the identified semantic entities can be generated; a first semantic association strength between a first semantic entity input and a second semantic entity input can be determined; and a second semantic association strength between the first semantic entity input and semantic entities associated with a semantic collection that is associated with the second semantic entity can be determined. An output can be provided based on the first and second semantic association strengths.Type: GrantFiled: July 7, 2021Date of Patent: February 13, 2024Assignee: nference, Inc.Inventors: Murali Aravamudan, Venkataramanan Soundararajan, Ajit Rajasekharan

Patent number: 11886474Abstract: In accordance with one or more embodiments of the invention, a method and system are provided of processing a search query entered by a user of a device having a text input interface with overloaded keys. The search query is directed at identifying an item from a set of items. Each of the items has one or more associated descriptors. The system receives from the user an ambiguous search query directed at identifying a desired item. The search query is a prefix substring of each of at least two words relating to the desired item. The system dynamically identifies a group of one or more items from the set of items having one or more descriptors matching the search query as the user enters each character of the search query. The system outputs identification of the one or more items of the identified group to be displayed on the device operated by the user.Type: GrantFiled: January 29, 2020Date of Patent: January 30, 2024Assignee: Veveo, Inc.Inventors: Sashikumar Venkataraman, Rakesh Barve, Pankaj Garg, Pranav Rajanala, Murali Aravamudan, Ajit Rajasekharan

Publication number: 20230315777Abstract: A method of selecting and presenting content based on learned user preferences is provided. The method includes providing a content system including a set of content items organized by genre characterizing the content items, and wherein the set of content items contains microgenre metadata further characterizing the content items. The method also includes receiving search input from the user for identifying desired content items and, in response, presenting a subset of content items to the user. The method further includes receiving content item selection actions from the user and analyzing the microgenre metadata within the selected content items to learn the preferred microgenres of the user. The method includes, in response to receiving subsequent user search input, selecting and presenting content items in an order that portrays as relatively more relevant those content items containing microgenre metadata that more closely match the learned microgenre preferences of the user.Type: ApplicationFiled: April 3, 2023Publication date: October 5, 2023Inventors: Murali Aravamudan, Ajit Rajasekharan, Kajamalai G.
