Embodiment 2
Step in the semantic query method of the resourceoriented tree that Fig. 2 provides for the embodiment of the present invention 2
A kind of flow chart of rapid S2, refers to Fig. 2, and the semantic query method that the present embodiment provides is with upper
The semantic query method stating embodiment 1 offer is similar, includes step S 1～S3 equally, due to step
Rapid S1～S3 there has been in embodiment 1 and describe in detail, does not repeats them here.
The difference of the application and above-described embodiment 1 is the most only described.Specifically, refer to Fig. 2,
Pre-set incidence relation table, incidence relation table for belonging to record description object object class and
The corresponding relation of the information relevant with semantic description resource.
Described step S2 includes:
S21, determines the object class belonging to involved description object according to the request of described semantic query, and
Search in described incidence relation table according to the described object class determined and retouch with described semanteme accordingly
State the information that resource is relevant.
S22, has with described semantic description resource under target resource information according to finding
The information closed, determines not only under the path that this target resource information is corresponding but also meet having of being found
The described semantic description resource allowing to access of pass information.
Specifically, in the present embodiment, the corresponding relation in described incidence relation table is: described
Object class and the path format one_to_one corresponding of this object class place semantic description resource.
In the case, described step S21, according to described semantic query request determine involved by retouch
State the object class belonging to object, and search in described incidence relation table according to the object class determined
The path format of corresponding described semantic description resource.
Described step S22, according to the described path found under target resource information, determines
Not only under the path that this target resource information is corresponding but also meet the institute allowing to access of this path format
State semantic description resource.
Citing below describes the semantic query method of the resourceoriented tree that the present embodiment 2 provides in detail.
This example is same resource tree with the resource tree of institute's illustrated example in above-described embodiment 1, at this not
Repeat again.On this basis, this semantic query method comprises the following steps:
Pre-set incidence relation table, specifically, when semantic information creates, record semantic information
In object class and the corresponding relation of semantic description resource path, and set up following incidence relation table:
| Object class | The path format of semantic description resource |
| m2m:WashMachine | http://www.M2Mplatform.com/devices/*/ |
| m2m:Operation | http://www.M2Mplatform.com/devices/*/*/ |
In actual applications, this incidence relation table is retouched also dependent on semanteme in the resource tree specified
The hierarchical relationship stating resource dynamically generates, as system regulation must be to device resource entity A
Under/device path, the description to this resource entity A must be on the road of this device resource entity
Under footpath, i.e./device/*/, the operating resource entity of this device resource entity must be at this device
Under the path of resource entity, the semantic description of this operating resource entity then must be provided in this operation
Under the path of source entity, i.e./device/*/*/.
S20, application A send semantic query request in order to search resource
WashMachine_A and the manufacturer's information of resource WashMachine_B, this semantic query is asked
In target resource address be http://www.M2Mplatform.com/devices/.
S21, receives semantic query request, and according to the description object in semantic query request and basis
Body determines that involved object class is WashMachine, and according to the object class determined
WashMachine searches corresponding semantic description resource in the incidence relation table pre-set
Path format be http://www.M2Mplatform.com/devices/*/.
In actual applications, if object class can be described in multiple semantic description resources, then
Employing tlv triple makes a distinction, and in tlv triple, first yuan is referred to as object, and second yuan is restriction relation,
Ternary is constraint；Above-mentioned so-called object class is first yuan of affiliated classification in tlv triple.
S22, the semantic description resource under target resource address includes
SemanticDescriptor_A, SemanticDescriptor_B, SemanticDescriptor_1 and
SemanticDescriptor_2, according to semantic description resource path lattice in these four semantic descriptions
Formula http://www.M2Mplatform.com/devices/*/determine both in this target resource information pair
The semantic description resource allowing to access meeting again this path format under the path answered is
SemanticDescriptor_A and SemanticDescriptor_B.
S23, merge semantic description resource SemanticDescriptor_A and
SemanticDescriptor_B。
S24, carries out semantic query in semantic description resource after merging.
S25, returns to Query Result apply A.Specifically, following Query Result is returned:
| Device (equipment) | Vendor (manufacturer) |
| WashMachine_A | Haier |
| WashMachine_B | Sumsung |
From the foregoing, it will be observed that use the semantic query method that the present embodiment provides, it can be seen that although language
Justice describes resource SemanticDescriptor_1 and SemanticDescriptor_2 at target resource
Under the path of address, but, not quilt under incidence relation form based on hiding link
In the range of being incorporated into the semantic information of semantic query, therefore, this relative embodiment 1 merges institute
For having the semantic description resource of permission, the speed of semantic query can be improved further.
Embodiment 3
Step in the semantic query method of the resourceoriented tree that Fig. 3 provides for the embodiment of the present invention 3
The another kind of flow chart of rapid S2, refers to Fig. 3, the semantic query method that the present embodiment provides with
The semantic query method that above-described embodiment 2 provides is similar, and the identical point of the two is the most superfluous at this
State.
The difference of the application and above-described embodiment 2 is the most only described.Specifically, refer to Fig. 3,
Corresponding relation in described incidence relation table is: the corresponding semantic description of each object class
Resource class, a semantic description resource can include multiple semantic description resource class.
Described step S21, determines belonging to involved description object according to the request of described semantic query
Object class, and search in described incidence relation table and this object according to the described object class determined
The semantic description resource class that class is corresponding.
Described step S22, according to the described semantic description money found under target resource information
Source category, determines not only under the path that this target resource information is corresponding but also meet this semantic description money
The described semantic description resource allowing to access of source category.
Citing below describes the semantic query method of the resourceoriented tree that the present embodiment 3 provides in detail.
This example is same resource tree with the resource tree of institute's illustrated example in above-described embodiment 1, at this not
Repeat again.On this basis, this semantic query method comprises the following steps:
Pre-build above-mentioned incidence relation table, in the present embodiment, at the semanteme of establishing resource tree
During information, set up the first subrelation table, for recording object class and semantic description resource class
Corresponding relation, also sets up the second subrelation table, be used for recording semantic description resource and path thereof and
The corresponding relation of semantic description resource class.Owing in m2m body, the basic class of top layer has
M2m:Device class and m2m:Operation class, m2m:WashMachine class belongs to Device
Class.
First subrelation table is as follows:
| Object class | Semantic resources classification |
| m2m:WashMachine | Type_Device |
| m2m:Operation | Type_Operation |
Second subrelation table is as follows:
S30, application A send semantic query request, it is therefore an objective to search WashMachine_A's
Manufacturer's information, the target resource address that the request of this semantic query includes is:
http://www.M2Mplatform.com/devices/WashMachine_A。
S31, receives semantic query request, and according to the target resource ground in the request of this semantic query
Location determines the semantic description resource allowing to access under target resource address path.It is specially semanteme
Resource SemanticDescriptor_A and SemanticDescriptor_1 are described.
S32, analyzes semantic inquiry request, and determines involved by query object according to m2m body
Object class be m2m:WashMachine；According to this object class m2m:WashMachine and
Above-mentioned incidence relation table determines that the semantic resources classification of correspondence is Type_Device.
S33, determines according to above-mentioned incidence relation table in the semantic description resource that step S31 determines
There is the semantic description resource of semantic description resource class Type_Device, finally determine both at this
The semantic description money of this semantic description resource class is met again under the path that target resource information is corresponding
Source is SemanticDescriptor_A.
S34, carries out language in semantic description resource SemanticDescriptor_A finally determined
Justice inquiry.
S35, is back to Query Result apply A.Query Result particularly as follows:
| Device (equipment) | Vendor (manufacturer) |
| WashMachine_A | Haier |
From the foregoing, it will be observed that the semantic query method that the present embodiment provides, it can be seen that although
SemanticDescriptor_A and SemanticDescriptor_1 is in inquiry target resource address
Path under, but, owing to platform above-mentioned incidence relation form based on hiding link is carried out
Pretreatment, therefore, the semantic information that only have selected SemanticDescriptor_A is looked into as semanteme
The scope ask, therefore, adopts and compares embodiment 1 in this way and merge the semanteme of all permissions and retouch
