Question

我想知道是否有任何系统/基础设施能够做一些人为推理过程，例如： Context: A is a pen Question: is A vertical or horizontal Reasoning process: 1. horizontal is anything parallel to the ground 2. A is parallel to the ground 3. A is horizontal

这个推理系统的最终目标是能够用一些预先定义的规则生成事实。

提前谢谢！

你可以通过本体来实现这一目标。您可以使用Protege这是一个配备了reasoners的免费本体编辑器来推断隐含知识。如下指定本体将实现期望的结果：

ObjectProperty: hasOrientation
    Domain: Object
    Range: Orientation

ObjectProperty: isParallel
    Domain: Object
    Range: Surface

Class: Object

Class: Orientation
    EquivalentTo: {Horizontal , Vertical}

Class: Pen
    SubClassOf: Object

Class: Surface
    EquivalentTo: {Ground , Rock , Wall}

Individual: Ground
    Types: Surface

Individual: Horizontal
    Types: Orientation    
    DifferentFrom: Vertical

Individual: Rock
    Types: Surface

Individual: Vertical
    Types: Orientation
    DifferentFrom: Horizontal

Individual: Wall
    Types: Surface

Individual: myPen
    Types: Pen
    Facts:  isParallel  Ground

Rule: 
    Pen(?aPen), isParallel(?aPen, Ground) -> hasOrientation(?aPen, Horizontal)
    Pen(?aPen), isParallel(?aPen, Wall) -> hasOrientation(?aPen, Vertical)

使用Pen(?aPen), isParallel(?aPen, Ground) -> hasOrientation(?aPen, Horizontal)进行推理，基本上表明如果aPen是Pen且aPen与isParallel关系Ground然后aPen有一个Horizontal方向。
