Using the Jet API

In addition to running JET stand-alone, you can use it as part of another application.  In this case jet.jar (i.e., jet-jar-1xx.zip) must be included among the libraries when running your application.  Here is a small sample program which uses Jet:

 1   import Jet.*;
 2   import Jet.Tipster.*;
 3   import java.util.Vector;
 4   import java.io.IOException;
 5
 6   class UseJet {
 7
 8   public static void main(String args[]) throws IOException {
 9     System.out.println("Starting UseJet...");
10     JetTest.initializeFromConfig("C:/My Documents/Jet/chunk3.properties");
11     String txt = "<TEXT>My first sentence to be analyzed for class.</TEXT>";
12     Document doc = new Document(txt);
13     Control.processDocument (doc, "", true, 1);
14     Vector v = doc.annotationsOfType("constit");
15     for (int i=0; i<v.size(); i++) {
16       Annotation a = (Annotation) v.get(i);
17       System.out.println ("Constit " + a.get("cat") + " over " + doc.text(a));
18       }
19     }
20   }

and a brief explanation of this program:

10
initializeFromConfig loads a JET properties file and all the associated resources (grammars, lexicons, patterns, HMMs, etc.).  The properties file should be the same as for a stand-alone run.
11-12
sets up the document to be analyzed.  By default, only text inside <TEXT> ... </TEXT> is analyzed.
13
processes the document.  The parameters to processDocument are
14-17
retrieve annotations of type constit from the document and print out, one per line, the cat feature of the annotation and the text spanned by the annotation
