Annotating a document with JAPE - gate

Question

I have been searching for a solution to this for weeks, I have some documents(about 95) that I am trying to classify using GATE. I have put them in one corpus I called training_corpus, however, after ANNIE has annotated the corpus, I have to go back into each file, select all token in the document, and create an annotation called Mention, with feature type and value the class for the document. for example:
type Start End id Features
Mention 0 70000 2588 {type=neg}
Is there anyway to automatically do this with JAPE? Basically, I want to select all tokens and create a new annotation with feature(type=class). Also, the class is appended to the document. Since there are many documents, can JAPE extract the class from the document name and set it to the value of Mentions feature. Example document name is neg_data1.txt, so the annotation will be Mention.type = neg?
Any help will be greatly appreciated. Thanks

I think you answered to your question by yourself.If the class assignment based on just a token present in text - why not simply process text outside of GATE?
For example to create an xml file like:
text and then use it in training process.
Also you can create a simple JAPE rule which will:
a) will take a text within document boundaries (see gate.Utils.length methods AFAIR)
b) based on presence of your token will create a new Annotation instance with features necessary.
an abstract example:
Phase: Instance
Input: Token
Options: control = once
Rule:Instance
(
{Token}
):instance
-->
{
AnnotationSet instances = outputAS.get("INSTANCE_ANNOTATION");
FeatureMap featureMap = Factory.newFeatureMap();
if (instances!=null&&!instances.isEmpty()){
featureMap.put("features when annotation presented in doc");
}else{
featureMap.put("features when annotation not in doc");
}
outputAS.add(new Long(0), new Long(documentLength), "Mention", featureMap);
}
