By following description also in conjunction with the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used to explain embodiments of the invention.
Description of drawings
Fig. 1 the present invention is based on the geographical Ontology Modeling of remote sensing image and the process flow diagram of dynamic dissemination method.
Embodiment
With reference now to accompanying drawing, describe embodiments of the invention, the similar elements label is represented similar elements in the accompanying drawing.
With reference to figure 1, present embodiment comprises the steps: based on the geographical Ontology Modeling and the dynamic dissemination method of remote sensing image
Step S1, the user is provided with user's realm information (UserField), and at exhaustive division and set up each other in the geographical main body system in two fields of semantic relation (utilizing in the field) at least and selected the field (Field) close to login with user's realm information (UserField) as forestry or soil, enter the visual interface of forming by dissimilar remote sensing objects, the semantic relation between the field of the built-in geographical body representative of user field and server is set up in preparation, and wherein the remote sensing object on the visual interface has used the geographical body of near field (Field) to classify;
Step S2, the notion of this area of user definition (temporarily with the NewClass name), select the remote sensing object (as forest) similar with the notion (notion NewClass) of described definition in a plurality of remote sensing of visual interface on to picture, the described remote sensing object of selecting constitutes to be gathered;
Step S3 judges whether all the remote sensing objects in the described set belong to the identical concept (representing with Class1) of the near field of selecting among the step S1 (Field), if change step S4 over to; If not (object in the remote sensing object set belongs to the different concepts of near field (Field) respectively, as D1, D2 and D3 etc.), change step S8 over to;
Step S4 determines that the user-defined notion (notion NewClass) and the identical concept (notion Class1) of described near field (Field) constitute synonymy;
Step S5 opens the corresponding XML file in user field (UserField) (with the F.xml name), judges that the F.xml file has or not the notion (notion NewClass) of described definition, if do not have, continues step S6, if having, changes step S7;
Step S6, set up the NewClass notion, new name is the node of " synonym ", a newly-built child node in " synonym " node, this child node is named with notion Class1, in this child node, add quantity parameter (count) and ratio parameter (ratio), wherein quantity parameter (count) represents that the Class1 notion of near field is considered to set notion (NewClass) with the user and is the number of times of synonymy, ratio parameter (ratio) expression count parameter and user set notion (NewClass) by the ratio of the total degree of all users' selections in the user field, ratio is used for the degree of confidence of semantic relation between the Class1 notion that the quantitative description user sets notion (NewClass) and Field field, changes step S12;
Step S7 according to user's selection, according to the method for step S6, upgrades quantity parameter (count), ratio calculated parameter (ratio), refreshes the value of two parameters, changes step S12;
Step S8 determines that user-defined notion (notion NewClass) is different concepts (the notion D of described near field (Field) 1, D 2And D 3) superordinate term;
Step S9 opens the corresponding XML file in user field (UserField) (with the F.xml name), judges that the F.xml file has or not the notion (notion NewClass) of described definition, if do not have, continues step S10, if having, changes step S11;
Step S10 sets up the NewClass notion, and new name is the node of " justice down ", sets up the plurality of sub node in " justice down " node, and the title of child node is used notion D among the step S3 respectively 1, D 2And D 3Deng name, as the following adopted notion of user definition notion (NewClass), and in these child nodes, all add quantity parameter (count), quantity parameter (count) is used for the selection preference of recording user for the number of times of adopted notion down occurring, changes step S12;
Step S11, the number of times of adopted notion upgrades the count parameter of corresponding node separately under using, and this reference record user's selection preference continues step S12;
Step S12 preserves the F.xml file, and the attribute of revising described F.xml file is read-only (for dynamic publishing process provides entry condition);
Step S13, the Agent1 (intelligent body 1) of server (server 1) end of user's login obtains the attribute of described F.xml file every time T;
Step S14 judges whether the attribute of described F.xml file is read-only, if, continue step S15, if not, change step S13;
Step S15, Agent1 send the content of described F.xml file, change step S13 (Agent1 reads, judges file attribute again, for transmission is next time prepared);
Step S16, the Agent2 (intelligent body 2) that is in blocked state on the reception server (server 2) monitors the content of whether receiving that Agent1 sends;
Step S17, when the Agent2 that is in blocked state received the content of Agent1 transmission, the state of Agent2 changed unimpeded state into;
Step S18, Agent2 writes local XML file (with F.xml file designation) with described content, and the state of Agent2 changes blocked state into, changes step S16 (Agent2 receives message again, for transmission is next time prepared).
As shown from the above technical solution, the geographical Ontology Modeling and the dynamic dissemination method that the present invention is based on remote sensing image mainly are to consider that (system comprises the field of two exhaustive divisions to the third party professional, as forestry and soil utilization) to the visual angle (S1) of current browsing information, by selected partly class in remote sensing image as sample set (step S2), according to the criteria for classification in user field sample is defined (to one's name department which or which ground class) then, its selected sample set of systematic analysis, add up its classification situation in known art: if the same class of the corresponding known art of all sample standard deviations of sample set, then user-defined class is with it synonymy (S4); If sample set comprises the class of a plurality of known art, then user-defined class is with it to go up justice relation (step S3).Add up all Query Results in user field then, and be written in the XML file (S5 to S12), form the dictionary of semantic relation between user's field concept and the known art notion, thereby set up the relation between the geographical body in two fields.System will send to other nodes to the XML file that upgraded real-time dynamicly, realize semantic share (S13 to S18).This method is utilized multiple dimensioned remotely-sensed data by general user's query script, sets up the semantic relation between the notion and specific area notion in the different field criteria for classification automatically, and by intelligent body (Agent) externally issue automatically.
The present invention is based on the geographical Ontology Modeling of remote sensing image and the advantage of dynamic dissemination method is:
1, by step S1 to S11, utilize the inquiry behavior on remote sensing image of field user, realize geographical Ontology Modeling, when having avoided dependence minority expert to set up geographical body, the cycle is long, the defective that subjectivity is strong;
2, the xml file by obtaining from S12, realized the formalization of semantic relation between the notion of specific body (utilizing body) in the notion and system in the frontier as forestry or soil, lay a good foundation for carrying out semantic reasoning, realized that the semanteme between all main body systems switches in frontier notion and the system, strengthened the ability of different field main body system interoperability;
3, at S13 in the step of S18, realize the dynamic issue of main body system by Agent, improved the range of application and the service efficiency of geographical body.
The present invention is based on geographical Ontology Modeling and dynamic publisher's ratio juris of remote sensing image below with a concrete example explanation.
The planning field user logins forestry ontology library (step S1), uses technology path of the present invention, attempts to set up in the geographical body of planning the semantic relation of related notion in " forest " and the geographical body of forestry;
" forest " is the notion in planning department that the user determines, establishes the user and is chosen in and selected 100 forest object sets (step S2) in the remote sensing image;
The total degree that this notion of sum attribute representation is selected by different user, suppose 100 times, " synonym " node is represented " forest " of planning set in forest department's synonym notion, sum represents to be assert synonymy number of times (being that the user sets the total degree that notion is selected by all users in the user field), suppose 90 times, the forest land of 80 corresponding field of forestry of selected remote sensing object set wherein, the opening (step S3) of 10 corresponding field of forestry of selected remote sensing object set;
" forest land " is the notion of forest department, be considered to planning department " forest " be synonym (step S4);
Open XML file (step S5), increase the forest notion newly and increase by two parameter c ount (for a certain notion of near field is considered to set the number of times that notion is a synonymy with the user) and ratio (for the ratio of county parameter and parameter s um), count represents number of times 80 times, and ratio represents ratio 80%;
" opening " is the notion of forest department, be considered to planning department " forest " be synonym, count represents number of times 10 times, ratio represents ratio 10% (step S6);
When determining " forest " notion 100 times, the incomplete corresponding identical concept of object (step S8) in the remote sensing object remote sensing object set of choosing for 10 times is arranged, wherein high forest occurs 10 times, and mangrove occurs 6 times, and bamboo grove occurs 7 times;
Open the xml file, (step S9) increases adopted node down, and sets up high forest, mangrove and three child nodes of bamboo grove, the interior quantity (step S10) that increases parameter c ount and insert corresponding conceptual object of each child node;
So far, system sets up following " planning .xml " file automatically:
It is to take place between which two relevant field that file is at first described semantic relation, as planning field and forestry.Then, the user such as forest, is assert number of times with this notion of sum attribute representation from the notion of field definition of oneself, supposes 100 times.
Under the forest notion, set up two nodes, respectively called after " synonym " and " justice down ".
Wherein " synonym " node is represented " forest " set in forest department's synonym notion, supposes that one has 90 times by identification synonymy number of times.Under this node, the notion that comprises in the near field that the user selects two and forest synonym: forest land and opening, two parameter c out and ratio are arranged respectively, if it is the synonym of planning field forest by assert that the forest land has 80 times, then its ratio value is 80% (80/100), in like manner, if opening is considered to the synonym of forest for 10 times, its ratio value is 10% (10/100), obviously, though from the synonym that the forest land and the opening of field of forestry all is considered to forest in the user field, forest land and forest are that the degree of confidence of synonymy is higher;
As for following adopted node, " forest " in expression user field if the set of notion adopted notion under forest department when determining " forest " notion 100 times, it is not identical concept entirely that the remote sensing object of choosing for 10 times is arranged, wherein high forest occurs 10 times, mangrove occurs 6 times, and bamboo grove occurs 7 times, and then adopted intranodal comprises three child nodes down: high forest, mangrove and bamboo grove, comprise parameter c ount respectively, the number of times that storage occurs separately.
Preserve file " planning .xml " file and revise its file attribute for reading, for dynamic publishing process provides entry condition (step S12);
Be responsible for circulation (every 60 seconds time) among the Agent1 of server 1 end and judge the attribute (S13) of " planning .xml " file, if file attribute is read-only, then it can stop the behavior of cycle criterion, starts the behavior (step S14) of revised file attribute;
The content of message transfer sends to Agent2 between content conduct of the transmission file behavior meeting general who starts " planning .xml " file and the Agent2 on the server 2; Restart the behavior of judging file attribute then, be transmission next time prepare (step S15);
A behavior that receives message is arranged among the Agent2 of server 2 ends, and it can be in blocked state always, up to receiving message (S16);
If message content is not empty, Agent2 can start the behavior (step S17) that writes this locality " planning .xml " file;
Agent2 reads the content of message, and content is write in the file of this locality " planning .xml " as the content sign indicating number.Can restart the behavior that receives message at last, for transmit prepare (step S18) next time.
Above invention has been described in conjunction with most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
