Introduction GraphParser (the first article) Exploit the structural and conceptual similarities between natural language and Freebase through a common graph-based representation. Formalize semantic parsing as a graph matching problem. Learn a semantic parser without using annotated question-answer pairs. Can create semantic parses for any type of NL sentences.
