Patent number: 11909902Abstract: A communication terminal and a method of providing a unified natural language interface to the same are disclosed. The method includes: determining, when text information containing many characters is created, whether the text information conforms to one of preset grammatical constraints; extracting, when the text information conforms to one of the grammatical constraints, tokens of one or more of characters from the text information, and extracting, when the text information does not conform to one of the grammatical constraints, one or more characters having an attribute probability higher than a reference probability as a token; and analyzing the extracted tokens to determine a function to handle the extracted tokens, and executing the determined function based on the extracted tokens.Type: GrantFiled: June 6, 2022Date of Patent: February 20, 2024Assignees: Samsung Electronics Co., Ltd., Sogang University Research & Commercialization FoundationInventors: Myeong Gi Jeong, Young Hee Park, Kwang Choon Kim, Jung Yun Seo, Choong Nyoung Seon
