Embodiment
Before technical scheme is introduced, the technical term being related to first to the program is briefly introduced：
True (Fact)：The information that the information and tasks carrying that user provides are produced；
Task (Task)：The information provided according to true (Fact), computer system performs sequence of operations and returned and holds
Row result；
Session (Context)：A series of interactions of the one-time continuous of one user and computer system；One session
The fact that during middle recording interactive (Fact) and task (Task)
Session can be also used for isolating the task (Task) and the fact (Fact) of different users；
Task stack (TaskStack)：The task (Task) being not carried out in a session (Context) is preserved, newly
Task (Task) is in stack top, and old task (Task) is at stack bottom；Task stack (TaskStack) supports the intersection of task to perform and go through
The execution again of history task；
True queue (FactList)：According to the sequencing of the time of addition, the institute in a session (Context) is preserved
Have true (Fact)；The effect of true queue (FactList) is the new and old of record true (Fact) so that can be according to the fact
(Fact) select facts (Fact)；
Task type (TaskType)：The general information of logger task (Task), including with true type (FactType)
First relation, specifically perform task (Task) class or script；
True type (FactType)：The general information of record true (Fact), including with task type (TaskType)
First relation, and interdependent first relation between true type (FactType)；Using between true type (FactType)
Relation, can prevent expired true (Fact) to be used by mistake.
Example one：Querying commodity information
User：Input a trade name or commodity id or goods links；
Machine：Identify the commodity；
User：How much；
Machine：Inquire about the price of commodity；
User：CPU is much；
Machine：Inquire about the CPU information of commodity.
In this simple interaction, price, CPU are that price under the true type of price is true, the true class of attribute respectively
CPU under type is true, and does not need user to input trade name (id) every time in interaction, is the thing preserved by session
Real (commodity id is true), come what is realized, this is a non-combined task type.Above-mentioned continuous interactive process constitutes a group session.
Example two：Commodity shopping guide
User：I wants to buy notebook；
Machine：It please input the notebook brand that you want to buy；
User：Apple；
Machine：It please input the Price Range of your receiving；
User：2000—4000；
Machine：Recommend qualified commodity.
This interaction is combined task type, contains recommendation task, attribute query task dispatching, recommends task to need
The facts such as brand, price, size, when user inputs the fact that point out, attribute query task is also relied on these facts, when required
When the fact that want is enough, each subtask is also completed, and then whole combined task is finished.
The man-machine interaction method based on scene that the application is provided, its fundamental design idea includes：
The graph of a relation set up between true type (FactType) and task type (TaskType), utilizes this graph of a relation
Set up the relation of true (Fact) and task (Task)；
Using the graph of a relation between true type (FactType) and task type (TaskType), task (Task) is checked
Whether the required fact (Fact) is enough；If so, corresponding according to being performed in the task type (TaskType) of this task (Task)
Task operating.
To make the technical principle, feature and technique effect of technical scheme clearer, below in conjunction with specific reality
Example is applied technical scheme is described in detail.
The initialization procedure for the man-machine interaction method based on scene that the embodiment of the present application is provided is as shown in figure 1, including such as
Lower step：
Step 101：The graph of a relation set up between task type (TaskType) and true type (FactType).For tight
Anxious and often changing for task and operation, while writing task type (TaskType) perform script, data storage is arrived in storage
In system.
Graph of a relation between the fact that the embodiment of the present application is provided type (FactType) and task type (TaskType)
As shown in Figure 2.Wherein, session is made up of a series of tasks and the fact, and each task belongs to specific task type, each thing
The fact that fall within specific in fact type.Task type (TaskType) includes combined task type (CompositeTaskType)
With internal task type (InnerTaskType).Combined task type can be decomposed into several subtask types to realize jointly；
Internal task type does not include subtask type then, can directly be performed.
Action type (OperationType) and true type (FactType) belong to metadata layer.Metadata layer is used for
Whole task and the true relation of required by task, and the operation performed by all tasks are described.For fixed task, with class
Form realize each specific task type (TaskType), action type (OperationType) and true type
(FactType).For task that is urgent and often changing, by these task type (TaskType), action types
(OperationType) stored in graph form in graphic data base with true type (FactType), can also be with object
Form, be stored in internal memory, an object is by a node in corresponding diagram, the side in association corresponding diagram between object.
Operation in task type (TaskType), action type (OperationType) is stored in the form of script.
Step 102：Dependence is set up between true type (FactType).If i.e. true type (FactType)
A depends on fact type (FactType) B, will remember in true type (FactType) A dependence (dependence) attribute
Copyist's real type (FactType) B reference.So when true type (FactType) B is not used, true type
(FactType) A can not be used again.
Step 103：Set up between task type (TaskType) and true type (FactType) and use relation.I.e. such as
The fact that really task (Task) of a task type (TaskType) needs to use fact type (FactType)
(Fact) come the operation of progress required for completing, then at required true (neededFact) of this task type (TaskType)

Step 305：According to the required fact of the task type (TaskType) recorded in task (Task) type attribute
(neededFact) the fact that recorded in attribute type (FactType), finds associated all true types (FactType)
And requirement；It is that these are true to be found all in this session (Context) according to these true types (FactType)
The fact that type (FactType) (Fact) (according to the type attribute of true (Fact)).
Step 306：The fact that will be found, sorts according to the backward for the time for adding session (Context), according to every
The dependence between true type (FactType) requirement, true (Fact) is planted (that is, if necessary to a fact
(Fact) the fact that the fact that the fact that A is relied on (Fact) B type (FactType) (Fact), then need the fact first
(Fact) B is added in required true (neededFact) attribute of task (Task), the fact (Fact) A could be added into task
(Task) in required true (neededFact) attribute), the fact that choose respective amount from the new to the old (Fact), by these things
The reference of real (Fact) is added in required true (neededFact) attribute of this task (Task).
Step 307：If having task (Task) in the task stack (TaskStack) of current sessions (Context), stack is taken
The task (Task) on top is as current task, and whether true (Fact) be enough needed for checking current task (Task)；If enough,
Perform step 308；If not enough, performing step 311.
