The outgoing direction connection is in the connection of other nodes in pointing to the knowledge mapping network for the first node；
Specifically, determine that the outgoing direction connection side of first node belongs to the first ratio of the first subgraph, including：Judge each
Whether one destination node is more than two to each path number of the Section Point, and each first object node is the first segment
Each node in addition to second keyword connected described in the outgoing direction connection side of point；Count on the path of the Section Point
The number of first object node of the number more than two；By the first mesh to the path number corresponding to the Section Point more than two
The number for marking node connects the number on side divided by the outgoing direction of the first node, obtains first ratio.
Step C：Determine that the direction connection side that enters of the Section Point in adjacent two nodes in the service path belongs to
Second ratio of first subgraph, wherein, it is described enter direction connection side be that the Section Point points to the knowledge mapping net
The connection side of other nodes in network.
Specifically, determine second ratio that direction connection side belongs to first subgraph that enters of Section Point, including：Judge
Whether each second destination node is more than two to the path number of the first node, and each second destination node is described second
The direction that enters of node connects each node in addition to the first node that side is connected；Count on the path of the first node

It is worth the intelligent home device that minimum service path determines interactive command control, it is seen that can using present invention method
Solve it is of the prior art when have multiple how can determine that service path carries out asking for intelligent home device control during responsive node
Topic.
Fig. 4 is the flow chart of the intelligent home equipment control method that the embodiment of the present invention two is based on knowledge mapping.Shown in Fig. 4
The executive agent of method can be the control device in Fig. 2.The process step of method shown in Fig. 4 includes：
Step S301：The interactive command of user input is obtained, for example, in Intelligent housing scene, control device is obtained
The interactive command for taking is " present indoor temperature is how many ", and specific acquisition methods may refer to embodiment one, and here is omitted.
Step S302:Each keyword is extracted from the interactive command of user input, for the interaction life in above-mentioned example
Make " present indoor temperature is how many ", the keyword for extracting is [" interior ", " temperature ", " being how many "], wherein being ordered from interaction
The method of keyword is extracted in order referring to embodiment one, here is omitted.
Step S303：Determine each keyword corresponding node in knowledge mapping network.
For example, when keyword be [" interior ", " temperature ", " being how many "] when, extracted from knowledge mapping network respectively with
Keyword " interior ", " temperature " and " being how many " corresponding node.
The schematic diagram of node corresponding with " interior ", " temperature " and " being how many " is shown such as Fig. 5 A to Fig. 5 D, in Fig. 5 A
The annexation between " interior " node, " temperature " node and " being how many " node is shown into Fig. 5 D, and is connected accordingly
Certain weighted value is allocated on edge fit in advance, specifically, the weighted value connected between node on side is represented between two nodes
The relevance of incidence relation, the relevance between bigger two nodes of weighted value is stronger, between smaller two nodes of weighted value
Relevance is weaker.
Step S304：Corresponding node, generation and each keyword corresponding node of difference are distinguished according to each keyword
Matrix.
In embodiment of the present invention scheme, the corresponding node of each described keyword can constitute a node matrix equation；
Node elements A in the node matrix equation of any one keywordiBjRepresent, AiBjValue be AiNode and BjBetween node
Weighted value on connection side, AiNode represents the corresponding node of current key word, BjNode is the AiThe adjacent node of node,
And the BjThe input time of node is later than the AiThe value of the input time of node, i and j is positive integer.
For example, the keyword " interior " " temperature " " being how many " in above-mentioned example is according to the input sequence in interactive command
Represented with R, P, Q respectively, each keyword inquired in knowledge mapping network is distinguished corresponding node and is respectively：R[r1,
R2, r3], P [p1, p2], Q [q1, q2, q3], wherein r, p, q is respectively the node in the corresponding knowledge mapping network of keyword.
Using the method for above-mentioned generation node matrix equation, obtain the corresponding node matrix equation of keyword R, P, Q and be respectively：
The corresponding node matrix equations of keyword R are
The corresponding node matrix equations of keyword P are
The corresponding node matrix equations of keyword Q are
Wherein, in above three matrix, cost values are the weighted value on connection side between two neighboring node, and the present invention is real
It refers to keyword corresponding to two nodes adjacent on input sequence to apply the two neighboring node in example.
Step S305：Treatment is ranked up to each node matrix equation.
Specifically, for node matrix equation each described, calculate every row node elements and value；According to often row node unit
Element and the descending order of value, adjust the order of each row node.
For example for R：Line1=cost (r1, p1)+cost (r1, p2)；Line2=cost (r2, p1)+cost
(r2, p2)；Line3=cost (r3, p1)+cost (r3, p2), if line1<line2<Line3 then R '=[line3, line2,
line1].Similarly to each row sequence of P, Q node matrix equation, node matrix equation P ', Q ' are obtained.
Step S306：According to order of each keyword in interactive command, each corresponding node of keyword section is determined
Each service path formed in knowledge mapping network.
Specifically, a node can be chosen from the corresponding node matrix equation of each keyword, each node of selection is pressed
Impinge upon the input sequence in the interactive command and map one service path of composition successively.Each section can be obtained in this way
The dot matrix all service paths to be combined into.For example, respectively from R ', P ', Q ' middle selection one indoor node, a temperature
Node and one are how many nodes, and according to interior-temperature-be that how many Sequential Mappings are a service path.
Step S307：Connection between the node in each service path while and during corresponding connection on
Weighted value, determines the cost value of each service path.
In embodiment of the present invention scheme, the computational methods of the cost value of each service path are：
One cost of service pathIts
In, i, j are two adjacent nodes of input time, and the input time of j is later than the input time of i；
Belong to the probability of same subgraph for node i and node j, represent in the triple being made up of a line and two summits and its
Product of the output of starting point i in the input of the ratio in the subgraph and terminal j in the subgraph, the physics of representative in subgraph
Implication is that two summits belong to an intensity level for subgraph in the triple.
As a example by with (r1, p1) in Fig. 6, Wherein
The determination methods that r1 is linked to the side number for being connected to other other subgraphs are that, for r1, for p1, r1's goes out outgoing direction connection side
Have 4 (X, Y, Z, p1).For X nodes, r1 to X has outgoing direction to connect side, but p1 to X except other lead to without other by r1
Road, then it is assumed that side (r1, X) be one be connected to other other subgraphs in connection, and Y, Z node can be by except r1
Node reaches p1,Similarly p1 it is all enter direction connection side beginning all have path with r1,
The cost value of all service paths is calculated using above-mentioned formula, wherein, calculating the cost value of each service path
When, the weighted value between two neighboring node is obtained from corresponding node matrix equation, if in a service path adjacent two
It is all zero that weighted value between individual node is expert at, then no longer carry out the calculating in follow-up business path, thus reducing business road
The calculating number in footpath, improves service path location efficiency.For example, calculate service path r2-p2-q2 service paths when, r2-p2 it
Between weighted value, the weighted value between p2-q2, the node elements that q2 weighted values are expert at all are zero, then no longer calculate r2-p2 it
Between weighted value, the weighted value between p2-q2, q2 weighted values are expert at, and the business road corresponding to subsequent rows node elements
The cost value in footpath.
Step S308：The minimum value in each service path cost value is determined, according to the corresponding business road of the minimum value
Footpath determines the intelligent home device of interactive command control.
In order to more clearly illustrate the control method of the embodiment of the present invention, present invention also provides one more specifically
Embodiment, including：
(1) interactive command of user input is " present indoor temperature is how many ", the key extracted from interactive command
Word is [" interior ", " temperature ", " being how many "].
(2) found from the knowledge mapping network for previously generating with each keyword corresponding node of difference such as Fig. 6
It is shown including：" interior " node 3, is represented with r, and collection is combined into R；" temperature " node 2, node is p, and node set is P；" it is
How much " node 3, being represented with q, collection is combined into Q, and the corresponding node matrix equation of each keyword is：
The corresponding node matrix equations of keyword R are
The corresponding node matrix equations of keyword P are
The corresponding node matrix equations of keyword Q are
The node matrix equation after node elements assignment and sequence to each node matrix equation is assumed to be：
It is indoorTemperatureIt is how manyThe often row sum to each matrix sorts respectively
Result is interior afterwardsTemperatureIt is how many
(3) it is service path starting point, the business road that the node found from Fig. 6 can be constituted with " interior " keyword
As shown in fig. 7, wherein, in the figure 7, weighted value is that 0 connection side is represented by dashed line between node in footpath.According to formulaIn calculating Fig. 7, the cost of all service paths
Value, and specify 0/0=+ ∞, wherein cos t values are the weighted value on side between node.
Specifically, initial mincost=0, the mincost=tempdisi if tempdisi is more than mincost, final choosing
It is target service path to take the service path representated by the maximum values of the i.e. mincost of path cost minimum.
In this example It is as follows according to step (2) interior joint calculative Path selection of matrix sort result：
Dis1=r1-p1-q1=0.86* (3/4) * (3/3)+0.66* (3/3) * (2/2)=0.645+0.66=1.305；
Because 1.305>Mincost, therefore mincost=1.305
Dis2=r1-p2-q1=0* (0/4) * (0/1)+0* (0/1) * (0/2)=0；Because 0<Mincost, does not change
Mincost values
Dis3=r2-p1-q1=0* (0/2)+0.66* (3/3) * (2/2)=0+0.66=0.66；Because 0.66<
Mincost, mincost values are not changed
Dis4=r2-p2-q1=0* (0/2) (0/1)+0* (0/1) (0/2)=0；Because 0<Mincost, does not change
Mincost values
(4) minimum cost value mincost=1.305 is selected, the path for representing is r1-p1-q1, this path smallest link value
