JAPE is a full-fledged rule- based system. l We will spend the lab working through a JAPE tutorial. l Go to http://gate.ac.uk/sale/talks/gate-course- may11/track-1/ and downloadhttp://gate.ac.uk/sale/talks/gate-course- may11/track-1/ –the presentation from module 3: module-3- jape.{pdf|ppt} –the data files from modules 2 and 3 : module-2-hands- on.zip and jape-hands-on.zip l As I get to the exercises, try them.

5. /(20) JAPE grammars A semantic tagger consists of a set of rule- based JAPE grammars run sequentially JAPE is a pattern-matching language The LHS of each rule contains patterns to be matched The RHS contains details of annotations (and optionally features) to be created More complex rules can also be created http://gate.ac.uk/sale/talks/annie-tutorial.ppt

6. /(20) LHS of the rule LHS is expressed in terms of existing annotations, and optionally features and their values Any annotation to be used must be included in the input header Any annotation not included in the input header will be ignored (e.g. whitespace) Each annotation is enclosed in curly braces Each pattern to be matched is enclosed in round brackets and has a label attached http://gate.ac.uk/sale/talks/annie-tutorial.ppt

7. /(20) RHS of the rule LHS and RHS are separated by  Label matches that on the LHS Annotation to be created follows the label (Annotation1):match  :match.NE = {feature1 = value1, feature2 = value2} http://gate.ac.uk/sale/talks/annie-tutorial.ppt

8. /(20) Using phases Grammars usually consist of several phases, run sequentially Only one rule within a single phase can fire Temporary annotations may be created in early phases and used as input for later phases Annotations from earlier phases may need to be combined or modified A definition phase (conventionally called main.jape) lists the phases to be used, in order Only the definition phase needs to be loaded http://gate.ac.uk/sale/talks/annie-tutorial.ppt

You should be able to add the university annotation to occurrences of: –Villanova University –Villanova (in the right context!) –‘Nova –University of Pennsylvania –Penn –UPenn
