Patent number: 11250039Abstract: A contextual label compression framework is presented that uses trained sequence to sequence models. A set of training data including received queries and related content can be processed to generate sequences of semantic encodings. These sequences can be used to train the sequence to sequence models, in order to be able to predict queries for instances of content when the relevant information for those instances is processed by the model. When such information is received for an instance, that information can be processed to generate a semantic encoding sequence which can then be processed by the model. A resulting semantic sequence output by the model can be segmented and decoded to produce a set of relevant queries for the instance of content. This information can then be provided to an entity associated with the instance of content for purposes in managing aspects relating to that content.Type: GrantFiled: December 6, 2018Date of Patent: February 15, 2022Assignee: A9.com, Inc.Inventors: Wei-Cheng Chang, Hsiang-Fu Yu, Inderjit Dhillon
