Patent number: 12249324Abstract: Data is received by an automated spoken language learning and assessment system that includes a passage of text comprising a response to stimulus material. Thereafter, at least one machine learning model is used to detect absent key points within the passage of text and/or location spans of key points in the passage of text. The at least one machine learning model can be trained using a corpus with annotated key points and a span for each key point. In addition, each of the detected key points is scored by at least one key point quality model to result in a corresponding key point score. Diagnostic feedback targeting content development skills is then determined based on the detecting and using the key point scores. Data can then be provided which characterizes such diagnostic feedback. Related apparatus, systems, techniques and articles are also described.Type: GrantFiled: May 13, 2021Date of Patent: March 11, 2025Assignee: Educational Testing ServiceInventors: Xinhao Wang, Klaus Zechner, Christopher Hamill

Patent number: 11455999Abstract: Data is received that encapsulates a spoken response to a prompt text comprising a string of words. Thereafter, the received data is transcribed into a string of words. The string of words is then compared with a prompt so that a similarity grid representation of the comparison can be generated that characterizes a level of similarity between the string of words in the spoken response and the string of words in the prompt text. The grid representation is then scored using at least one machine learning model. The score indicates a likelihood of the spoken response having been off-topic. Data providing the encapsulated score can then be provided. Related apparatus, systems, techniques and articles are also described.Type: GrantFiled: April 9, 2020Date of Patent: September 27, 2022Assignee: Educational Testing ServiceInventors: Xinhao Wang, Su-Youn Yoon, Keelan Evanini, Klaus Zechner, Yao Qian

Patent number: 10380490Abstract: Computer-based systems and methods are provided for generating a narrative computer scoring model for assessing story narratives. In one embodiment, supervised machine learning is used to generate the narrative computer scoring model. For example, a collection of training story narratives with assigned scores may be used to train the model. In one embodiment, each training story narrative is processed to extract features that signify content relevance, collocation of commonly used words, coherency, detailing, and expressions of sentiment. These features, as well as others, may be selectively used to train a narrative computer scoring model. Once trained, the model can be used to automatically evaluate story narratives and assign appropriate scores.Type: GrantFiled: February 26, 2016Date of Patent: August 13, 2019Assignee: Educational Testing ServiceInventors: Swapna Somasundaran, Chong Min Lee, Martin Chodorow, Xinhao Wang
