====== HaQuNa ====== HeaRTDroid Query Notation is a simple language that can be used in an interactive commandline shell to load, modify, run HMR+ models. Source code can be downloaded from [[https://bitbucket.org/sbobek/heartdroid/downloads|HeaRTDroid repository]] Most recent release can be downloaded from here {{:pub:software:heartdroid:tutorials:haquna-1.0.7.jar|HaQuNa}} v. 1.0.7. You should have at least Java 7 to run HaQuNa. ===== Interactive mode ===== To run HaQuNa in interactive mode go to the directory where you saved ''haquna.jar'' and type in console


java -cp haquna.jar:. haquna.HaqunaMain

===== Non-interactive mode===== ====Running scripts==== You can run a script, which is a set of commands in HQN notation in non-interactive mode. To run a script that will printout the result to standard output run:


java -cp haquna.jar:. haquna.HaqunaMain script.hqn

If you wish to run a script, but after that open a console, run


java -cp haquna.jar:. haquna.HaqunaMain --console (or -c) script.hqn

====Running inference mode==== HaQuNa allows you to run inference for selected models from bash. The result of the reasoning will be printed to standard output. The command-line options of HaQuNa are presented below

java -cp haquna.jar:. haquna.HaqunaMain --model model.hmr \
  --tables ['Table1','Table2'] \                     # mandatory only for foi 
  --inference [ddi|gdi|foi] \                        # optional, default = ddi
  --initial-state [att-name=value, att-name=value] \ # optional
  --conflict-resolution  [all|last|first] \          # optional, default first
  --tokens [on|off] \                                # optional, default off
  --uncertainty [on|off]                             # optional, default on

===== Language specification ===== ====Loading model from file==== myModel = new Model('model.hmr') ====Loading model from URL==== myModel = new Model('http://example.com/model.hmr') ====Saving model to file==== myModel.save('/path/to/file/') ====Running inference==== * With WorkingMemory object that stores initial state passed as a parameter:myModel.run(wm, //optional parameters//) * Without WorkingMemory (initial state has to be loaded by attributes' callbacks): workinMemory = myModel.run(//optional parameters//) * Optional parameters may be arbitrary permutation of the following * Inference strategy: inference=gdi|ddi|foi // default ddi * Token passing: tokens=on|off // default on * Uncertainty handling with CF algebra: uncertainty=on|off // default on * Conflict resolution strategy: conflict_resolution=first|last|all // default first * List of tables to process: tables=['tableName1','tableName2', ...] // mandatory only for foi mode * Examples: * myModel.run(wm, inference=gdi, tables=['Table3']) * wm = myModel.run(inference=foi, tables=['Table1','Table2','Table3']) ====Running scripts==== For details on running scripts see [[#non-interactive_mode|Non-interactive mode]] load('script.hqn') ====Getters for model objects==== * List all the tables in XTT2 model: myModel.showTablesList() * List all attributes names form XTT2 mdoel: myModel.showAttributesList() * List all types from XTT2 model: myModel.showTypesList() * Getting XTT2 table from a model:

myTab = myModel.getTableByName('name')
myTab = myModel.getTableById('id')

* Getting attribute from a model:

myAttr = myModel.getAttributeByName('name')
myAttr = myModel.getAttributeById('id')

* Getting type from a model:

myType = myModel.getTypeByName('name')
myType = myModel.getTypeById('id')

====Getters for particular elements of XTT2 model==== * For Attribute objects: * myAttr.show() * myType = myAttr.getType() * myCallback = myAttr.getCallback() * For Type objects: myType.show() * For Table objects:

myTab.show()
myRule = myTab.getRuleByName('name')
myRule = myTab.getRuleById('id')

* For Rule objects:myRule.show() * For Callback objects: myCallback.show() ====Creating components==== * Types: newType = new Type('hmrCode') * Attributes: newAttr = new Attribute('hmrCode') * Tables: newTab = new Table('hmrCode'); * Rules: newRule= new Rule(<'hmrCode'); ====Modifying XTT2 model==== Original model stays intact * Adding components: * Types: newModel = oldModel.add(myType) * Attributes: newModel = oldModel.add(myAttr) * Tables: newModel = oldModel.add(myTable) * Rules: newModel = oldModel.add(myRule) * Removing components: * Types: newModel = oldModel.remove('typeName') * Attribtues: newModel = oldModel.remove('attrName') * Tables: newModel = oldModel.remove('tabName') * Rules: newModel = oldModel.remove('ruleName') ====State management via Working Memory object==== * Creating Working Memory object: wm = new WorkingMemory(myModel) * Getting all values of attributes stored by WM: wm.showValueOf('attrName') * Setting values of attributes stored in WM (the value after **#** represents a certainty factor assigned to the value):

wm.setValueOf('attrName','attrValue')
wm.setValueOf('attrName','attrValue#cf')

* Getting attribute value from a given point in history: WM.showValueOf('attrName', -1h) * Printing current state (current values of all attributes): wm.showCurrentState()
