The fact that described in present embodiment knowledge: the knowledge in relation to some facts, such as the classification of things, attribute, science
The fact, objective fact etc..It emphasizes the static state of knowledge, that is, describes the attribute and its correlation of things.Such as, the current body temperature of old man is
37.5 degree are a fact knowledge.
Procedural knowledge: procedural knowledge be in relation to " what if " knowledge.It emphasizes the dynamic of knowledge, i.e., expression reasoning and
Relevant fact etc. is searched for the process of knowledge.The solution procedure of its relevant issues, skill sex knowledge tell how to make one
Thing.
Rule knowledge: usually there is causal knowledge.Such as, if current time is the morning, the behavior of old man is anticipated
It is willing to trot out.
In present embodiment, it is related to all kinds of knowledge such as true, process and rule, needs to use different types of knowledge
A kind of unified representation.The form of expression for using frame, fact knowledge, procedural knowledge and rule knowledge are all fused to
In frame, knowledge representation method that there is satisfactory texture, complete is formed.The knowledge table based on frame is used in present embodiment
Show that method, basic framework consist of three parts:
One, regular troughs (Slot): the place that frame stores information is mainly slot (Slot), and each slot again can be by several sides
(facet) is formed in face.One slot indicates an attribute of object, and a side is used to describe the one aspect of respective attributes.
Value possessed by slot and side is referred to as slot value and side value.In a knowledge system with frame representation, generally all contain
There are multiple frames, in order to distinguish the different slots in different frame and a frame, not ipsilateral, needs to assign difference respectively
Name, be referred to as frame name, slot name and facet name.
In general slot value can there are several types of types:
Occurrence, the value are given by actual conditions；
Process values, the value are a calculating process, it utilizes other slot values of the frame, carry out by given calculating process based on
Obtained occurrence (such as a certain method)；
Another frame name just constitutes frame calling, material is thus formed a frames when slot value is another frame name
Chain, related frame aggregate, which is got up, just forms frame system.
The slot of frame can be with additional process, referred to as process attachment, including subprogram and certain reasoning process.It is common attached
Process is added to have:
If-needed: once affiliated slot value will be used (inquiry), then start subsequent additional process；
If-added: once affiliated slot value will be assigned (modification), then start subsequent additional process；
Two, method slot (Methods): method slot is used to store the method in object, it is a kind of special in frame
Dynamic process.The structure of method is defined by method name, method local variable and method procedure body is constituted.When method be triggered with
Afterwards, required information is filtered out from the message of transmission to use for method procedure body, then executes method procedure body.
Three, regular slot (Rules): regular slot is used to store production rule collection, and each rule set is placed on as a value
In regular slot.Each rule leaves several rules concentratedly.
Static attribute of frame etc. is indicated with regular troughs in present embodiment.Each regular troughs are with " facet name side value "
Form is indicated, meanwhile, two processes, i.e. if-needed and if-added are added for each side value.I.e. when side value quilt
When using and being assigned, corresponding method in frame is triggered respectively.Herein, additional process is option.
For regular slot, we use the form of " rule number, rule body " to be indicated；For method slot, we are used
The form of " Method method name " is indicated.Wherein the definition procedure of specific method is completed outside frame, according to Method
Method name, local variable define, the mode of method procedure body is expressed.
Be using the advantages of above-mentioned knowledge representation method based on frame: frame knowledge representation method uses " slot name side
The unified structure of name side value ", it is concise, it can be readily appreciated that meeting the thinking habit of people.Frame knowledge representation method will be more
The single knowledge representation method of kind (rule, frame and process) is fused into a frame, adequately expresses true, process and rule
All kinds of static and dynamic and the knowledge such as then, compensate for the defect of single knowledge token method.
Using a unified, pervasive knowledge representation method based on frame in present embodiment, is integrated and united with this
The representation of knowledge form of one different agencies.Knowledge can thus be showed with certain mode and be stored in computer
It goes, but to enable a computer to infer unknown knowledge with the knowledge grasped, it is necessary to which knowledge is made inferences.
Reasoning, which refers to the process of, releases conclusion from the existing fact according to certain rule.Data are based on using a kind of herein
The mode of the forward reasoning of driving.The agency from external received message is needed, adding for slot (is passed through using method call first
Journey) mode fill the slot value of knowledge frame；Then, reasoning process is just carried out in lower portion, and traversal rule slot is found
