Question

我正在尝试使用opennlp处理文档分类器。但是我在培训文件上遇到了困难。当opennlp正在读取文件时，我收到以下错误：

Indexing events using cutoff of 5

    Computing event counts...  done. 17 events
    Indexing...  Dropped event greetings:[bow=hello]
Dropped event greetings:[bow=hi]
Dropped event greetings:[bow=salam]
Dropped event internet_problem:[bow=internet]
Dropped event internet_problem:[bow=no, bow=data]
Dropped event internet_problem:[bow=data, bow=not, bow=working]
Dropped event internet_problem:[bow=not, bow=able, bow=to, bow=open, bow=website]
Dropped event internet_problem:[bow=browsing, bow=issue]
Dropped event balance_problem:[bow=balance]
Dropped event balance_problem:[bow=usage]
Dropped event balance_problem:[bow=bill, bow=amount]
Dropped event balance_problem:[bow=billed]
Dropped event voice_problem:[bow=signals]
Dropped event voice_problem:[bow=call]
Dropped event voice_problem:[bow=voice]
Dropped event voice_problem:[bow=call, bow=drop]
Dropped event voice_problem:[bow=not, bow=connecting]
done.

我的培训文件如下：

greetings hello
greetings hi
greetings salam
internet_problem internet
internet_problem no data
internet_problem data not working
internet_problem not able to open website
internet_problem browsing issue
balance_problem balance
balance_problem usage
balance_problem bill amount
balance_problem billed
voice_problem signals
voice_problem call
voice_problem voice
voice_problem call drop
voice_problem not connecting

我没有得到我可能错过的东西。

第一行显示var objectoriginalX:Number; var objectoriginalY:Number; Atom.buttonMode = true; Atom.addEventListener(MouseEvent.MOUSE_DOWN, pickupObject); Atom.addEventListener(MouseEvent.MOUSE_UP, dropObject); Matter.buttonMode = true; Matter.addEventListener(MouseEvent.MOUSE_DOWN, pickupObject); Matter.addEventListener(MouseEvent.MOUSE_UP, dropObject); function pickupObject(event:MouseEvent):void { event.target.startDrag(); event.target.parent.addChild(event.target); } var dropCount:int = 0; var dbCount:int=0; var dbutton0; function dropObject (event:MouseEvent):void { event.target.stopDrag(); var targetName = Answer1; trace (targetName); var matchingTarget:DisplayObject = getChildByName(targetName); if (event.target.dropTarget != null && event.target.dropTarget.parent == answer[1].dest) // red flag here! //dest is a String and .parent is a MovieClip. //They can never be equal. This block of code would never run like this. { event.target.removeEventListener(MouseEvent.MOUSE_DOWN, pickupObject); event.target.removeEventListener(MouseEvent.MOUSE_UP, dropObject); event.target.buttonMode = false; alpha = .8 dropCount ++; event.target.x = 10 event.target.y = (Number(dropCount) * 100); trace ("hit"); trace (dropCount); } else { event.target.x = 100; event.target.y = 111; trace ("miss"); } } var answer:Array = [ {_name:"gravel",dest:"1"}, {_name:"Nuts and bolts",dest:"Answer1"}, {_name:"water",dest:"2"}, {_name:"gold",dest:"3"}, {_name:"Iron",dest:"4"} ]; text3.text = answer[1]._name; var myText:TextField = new TextField(); Atom.addChild(myText); myText.text = answer[1]._name;

这可能意味着您必须至少给出5个分类示例。所以，在训练数据中没有5的地方为Indexing events using cutoff of 5和其他人提供另外两个例子。

或者，如果您没有足够的训练数据，可以将截止值减少到3，但这不会给您带来好的结果。

希望这有帮助！
