Publication number: 20210149964Abstract: Disclosed are some implementations of systems, apparatus, methods and computer program products for integrating question generation and answer retrieval in a question answer system. The system generates a question using a set of documents and determines whether it is semantically distinct from questions in a question-answer repository. After determining that the question is semantically distinct from questions in the question-answer repository, the system adds the question to the question-answer repository. Upon receipt of a user-submitted question, the system uses the question-answer repository to identify a semantically similar question. The system retrieves an answer corresponding to the identified question from the question-answer repository and provides the answer in response to the user-submitted question.Type: ApplicationFiled: November 15, 2019Publication date: May 20, 2021Inventors: Yuanxin Wang, Anuprit Kale, Zachary Alexander, Na Cheng

Patent number: 10853577Abstract: A data processing system analyzes a corpus of conversation data received at an interactive conversation service to train a response recommendation model. The response recommendation model generates response vectors based on custom responses and using the trained model and generates a context vector based on received input at the interactive conversation service. The context vector is compared to the set of response vectors to identify a set of recommended responses, which are recommended to an agent conversing with a user using the interactive conversation service.Type: GrantFiled: September 21, 2018Date of Patent: December 1, 2020Assignee: salesforce.com, inc.Inventors: Zachary Alexander, Jayesh Govindarajan, Peter White, Weiping Peng, Colleen Smith, Vishal Shah, Jacob Nathaniel Huffman, Alejandro Gabriel Perez Rodriguez, Edgar Gerardo Velasco, Na Cheng
