Publication number: 20210097978Abstract: A chatbot system receives utterances of a conversation. The chatbot system constructs a conversation knowledge graph comprising one or more dialogue segments that correspond to utterances of the conversation. The chatbot system identifies a dialogue segment in the conversation knowledge graph having a contextual uncertainty that is detected based on a context model. The chatbot system generates a clarifying question for the identified dialogue segment having the contextual uncertainty. The chatbot system receives a clarifying answer from a user interface of the computing device to the clarifying question. The chatbot system updates the context model and the conversation knowledge graph based on the clarifying question and the clarifying answer to resolve the contextual uncertainty of the identified dialogue segment.Type: ApplicationFiled: September 28, 2019Publication date: April 1, 2021Inventors: Lijun Mei, Qi Cheng Li, Xin Zhou, Xue Han, Yan Fei Wang

Publication number: 20210089528Abstract: A system, program product, and method for use with an artificial intelligence (AI) platform to dynamically amend a knowledge base responsive to query evaluating and processing. A received or detected query is subject to natural language processing to identify, annotate, and map one or more query tokens against a knowledge base. The query tokens are evaluated against the knowledge base to identify one or more query tokens absent from the knowledge base and leverage a neural network to predict a probability relationship between the query tokens absent from the knowledge base and one or more tokens populated in the knowledge base. The natural language (NL) query is translated to a structured query language (SQL) and the SQL query is executed and evaluated, and the knowledge base is selectively and dynamically amended subject to the SQL evaluation.Type: ApplicationFiled: September 19, 2019Publication date: March 25, 2021Applicant: International Business Machines CorporationInventors: Chen Lin, John Rofrano, Anup Kalia, Maja Vukovic, Jinho Hwang, Jie Ma, Lijun Mei, Ya Bin Dang
