What is deep case?

Deep case refers to the analysis of syntactic relationships, where a sentence structure is examined to understand how the different components of the sentence are related to each other. In deep case analysis, the focus is on the meanings of the individual words in a sentence, rather than just their surface forms. This type of analysis helps to identify how the subject, object, and predicate of a sentence are related, and can provide insights into the relationships between different elements in a sentence. Deep case analysis is commonly used in linguistic research, particularly in the field of natural language processing, and can be used to inform the development of algorithms to understand and analyze natural language text.
