Patent number: 11120701Abstract: A method and system of providing education content to a student is provided. A topic to be taught to a student is received. A user model of the student is identified. An electronic content model for the topic is determined. One or more presentation templates are identified based on the electronic content model. A concept map is determined based on the one or more presentation templates. A presentation template is selected from the one or more presentation templates. A segment of an educational content of the topic is provided to a user device of the student, based on the selected presentation template.Type: GrantFiled: February 26, 2020Date of Patent: September 14, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jae-Wook Ahn, Maria D.

Patent number: 10984196Abstract: Method and apparatus for generating natural language observations using sequence-to-sequence models are provided. The method includes receiving a first electronic document and dynamically generating, without requiring user intervention, a first natural language observation corresponding to a first portion of the first electronic document by processing the first portion of the first electronic document using a first sequence-to-sequence model. A second natural language observation is received for the first portion of the first electronic document, and the generated first natural language observation and the authoritative natural language observation are provided. The method further includes receiving an evaluation of the first natural language observation and the second natural language observation, and refining the first sequence-to-sequence model based on the evaluation of the first natural language observation and second natural language observation.Type: GrantFiled: January 11, 2018Date of Patent: April 20, 2021Assignee: International Business Machines CorporationInventors: Patrick D. Watson, Maria D. Chang, Jae-Wook Ahn, Sharad Sundararajan, Tengfei Ma

Patent number: 10832586Abstract: A method and system of interactive tutoring is provided. A question is sent to a user device. Upon determining that the response does not correspond to a known correct answer, a concept map is identified and a cost function between the correct answer and the response is determined. Upon determining that the cost function between the correct answer and the response is above a predetermined threshold, the question is identified to be the origin. Otherwise, the response is identified to be the origin. A present academic proficiency of the student is determined. A difficulty boundary based on the academic proficiency of the student is determined. A next question is provided between the origin and the correct answer, based on the determined difficulty boundary of the student.Type: GrantFiled: April 12, 2017Date of Patent: November 10, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shazia Afzal, Jae-wook Ahn, Maria D. Chang, Renuka R. Sindhgatta, Patrick D. Watson

Patent number: 10659239Abstract: Techniques facilitating using a blockchain system that integrates the trustworthiness of the blockchain concept with open scientific research by generating a blockchain of the experiments formed, data collected, analyses performed, and results achieved are provided herein. In an example, the blockchain system can form a blockchain representing a research project, wherein the blockchain comprises a first block of research data and a second block of analysis data representing a log of an analysis performed on the research data. Summary blocks and correction blocks can also be added to the blockchain representing the post analysis of the research results. One or more of the subsequent blocks can be linked to the preceding blocks using information in block headers that can also serve to determine whether modifications to the blocks have been performed.Type: GrantFiled: March 20, 2019Date of Patent: May 19, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jae-Wook Ahn, Maria D. Chang, Ravindranath Kokku, Patrick Watson
