Roger Carl Schank (March 12, 1946 – January 29, 2023) was an American artificial intelligence theorist, cognitive psychologist, learning scientist, educational reformer, and entrepreneur. Beginning in the late 1960s, he pioneered conceptual dependency theory (within the context of natural language understanding ) and case-based reasoning ...
Conceptual dependency theory is a model of natural language understanding used in artificial intelligence systems. Roger Schank at Stanford University introduced the model in 1969, in the early days of artificial intelligence. [ 1 ]
In 1969 Roger Schank introduced the conceptual dependency theory for natural language understanding. [3] This model, partially influenced by the work of Sydney Lamb, was extensively used by Schank's students at Yale University, such as Robert Wilensky, Wendy Lehnert, and Janet Kolodner.
The natural approach is a method of language teaching developed by Stephen Krashen and Tracy Terrell in the late 1970s and early 1980s. The Natural Approach has been used in ESL classes as well as foreign language classes for people of all ages and in various educational settings, from primary schools to universities. [ 1 ]
With James H. Martin, he wrote the textbook Speech and Language Processing: An Introduction to Natural Language Processing, Speech Recognition, and Computational Linguistics; Roger Schank – introduced the conceptual dependency theory for natural-language understanding. [23] Jean E. Fox Tree – Alan Turing – originator of the Turing Test.
Roger Schank, Robert P. Abelson and their research group, extended Tomkins' scripts and used them in early artificial intelligence work as a method of representing procedural knowledge. [1] In their work, scripts are very much like frames , except the values that fill the slots must be ordered.
The distinction between neat and scruffy originated in the mid-1970s, by Roger Schank.Schank used the terms to characterize the difference between his work on natural language processing (which represented commonsense knowledge in the form of large amorphous semantic networks) from the work of John McCarthy, Allen Newell, Herbert A. Simon, Robert Kowalski and others whose work was based on ...
The main purpose of theories of second-language acquisition (SLA) is to shed light on how people who already know one language learn a second language. The field of second-language acquisition involves various contributions, such as linguistics, sociolinguistics, psychology, cognitive science, neuroscience, and education. These multiple fields ...
