Abstract
By extending logic grammars with constraint logic, we give them the ability to create knowledge bases that represent the meaning of an input string. Semantic information is thus defined through extragrammatical means, and a sentence's meaning logically follows as a byproduct of string rewriting. We formalize these ideas, and exemplify them both within and outside firstorder logic, and for both fixed and dynamic knowledge bases. Within the latter variety, we consider the usual lefttoright derivations that are traditional in logic grammars, but also  in a significant departure from the norm  arbitrary (i.e., orderindependent) derivations.
We show that rich and accurate knowledge extraction from text can be achieved through the use of this new formalism
