ALE is a software which integrates phrase structure parsing, semantic-head-driven generation and constraint logic programming with typed feature structures as terms. This generalizes both the feature structures of PATR-II and the terms of Prolog II to allow type inheritance and appropriateness specifications for features and values. Arbitrary constraints may be attached to types, and types may be declared as having extensional structural identity conditions. Grammars may also interleave unification steps with logic program goal calls (as can be done in DCGs), thus allowing parsing to be interleaved with other system components.
