Patent number: 11631338Abstract: Digital learning or tutoring systems as described herein embed, by a trained machine learning knowledge tracing engine, an array for learner interactions X into a static representation ej corresponding to a prior learner interaction xj and determine a contextualized interaction representation hj based on this. Digital tutoring systems described herein calculate, by a masked attention layer of the trained machine learning knowledge tracing engine, an attention weight Aij based on a time gap between two learner interactions with the system, and can calculate a contextualized interaction representation hj, wherein the contextualized interaction representation hj is proportional to the attention weight Aij. The systems can provide for display at the GUI a second question item based on the contextualized interaction representation hj, the second question item corresponding to a recommended learner recommendation.Type: GrantFiled: June 11, 2020Date of Patent: April 18, 2023Assignee: ACT, INC.Inventors: Shi Pu, Michael Yudelson, Lu Ou, Yuchi Huang

Patent number: 11494560Abstract: The present disclosure provides systems and methods for providing interface rendering of passages for test item generation. Methods and systems can utilize natural language processing (NLP) and machine learning (ML) models to analyze passages that were provided in historical testing environments (e.g., first passage), determine one or more similar search strings that are also found in a current passage (e.g., second passage), and provide the first and second passages to a user interface of a user device. On the display, the search string in the historical and current passages may be highlighted at the user interface to identify the similarities.Type: GrantFiled: January 30, 2020Date of Patent: November 8, 2022Assignee: ACT, INC.Inventor: Richard D.

Patent number: 10755589Abstract: A computerized system for scoring constructed responses to one or more prompts. The system receives a plurality of constructed responses in an electronic font-based format and separates the plurality of constructed responses into a first group of constructed responses that are scorable by the system and a second group of constructed responses that are not scorable by the system. The constructed responses in the first group are assigned scores based on predetermined rules, and the scores are sent to a score database. In a preferred embodiment, the first group includes constructed responses that do not answer the prompt and constructed responses that match pre-scored responses. The second group of constructed responses are sent by the system to a hand-scorer for manual scoring.Type: GrantFiled: October 30, 2014Date of Patent: August 25, 2020Assignee: ACT, INC.Inventors: Susan M.
