A short introduction to modern grammars of natural language. Use the fundamentals of generative grammar to learn about syntax (the grammar & rules of sentences). Follow along as I work through the structure of a simple sentence, building a parse tree for that sentence with X-Bar Theory. Learn to walk through the tree, compare types of structures and identify ambiguities. Basic but helpful for nonspecialists interested in computational grammars, the syntax of native & foreign languages, and natural language processing.
