JAPE (linguistics)
Encyclopedia
JAPE is the Java Annotation Patterns Engine, a component of the open-source General Architecture for Text Engineering
(GATE) platform. JAPE is a finite state transducer
that operates over annotations based on regular expressions. Thus it is useful for pattern-matching, semantic extraction, and many other operations over syntactic trees such as those produced by natural language parsers.
JAPE is a version of CPSL – Common Pattern Specification Language.
A JAPE grammar consists of a set of phases, each of which consists of a set of pattern/action rules. The phases run sequentially and constitute a cascade of finite state transducers over annotations. The left-hand-side (LHS) of the rules consist of an annotation pattern description. The right-hand-side (RHS) consists of annotation manipulation statements. Annotations matched on the LHS of a rule may be referred to on the RHS by means of labels that are attached to pattern elements.
General Architecture for Text Engineering
General Architecture for Text Engineering or GATE is a Java suite of tools originally developed at the University of Sheffield beginning in 1995 and now used worldwide by a wide community of scientists, companies, teachers and students for all sorts of natural language processing tasks, including...

Finite state transducer
A finite state transducer is a finite state machine with two tapes: an input tape and an output tape. This contrasts with an ordinary finite state automaton , which has a single tape.-Overview:...
