| - | ===== Fuzzy Semantic Petri Nets ===== | + | ==INDECT== |
| - | Fuzzy Semantic Petri Nets (FSPN) are Petri nets coupled with an underlying fuzzy ontology. | + | Informacje o projekcie: [[http://www.indect-project.eu/]] |
| - | *The fuzzy ontology stores facts about a development of a certain complex event (or a process). They are expressed as fuzzy unary or binary relations between participating objects. The ontology ABox is updated with new observations. | + | Współautor raportów: |
| - | *The Petri net defines a scenario of an event (or a process, if you like), its places correspond to the scenario steps | + | |
| - | *Tokens in FSPN represent combinations of objects participating in the event. They are attributed with weights expressing likelihood of a scenario step occurrence | + | |
| - | *Guards in FSPN are conjunctions of fuzzy predicates referencing the assertions in the coupled ontology | + | |
| - | FSPN were applied to the problem of video event recognition. In the presented example an abandonned laguagge is correctly detected. (The event scenario and the dataset were published at [[http://www.cvg.rdg.ac.uk/PETS2006/|PETS 2006 Workshop]]) . | + | *D6.4 Ontology and automatic reasoning in crisis management - definitions and concepts, [[http://www.indect-project.eu/files/deliverables/public/d6.4/view]] |

| - | Scenario: | + | |
| - | -A man enters the scene and is still for some time | + | |
| - | -Then he takes his rucksack off and puts it on the floor. He stays close to it for some time. | + | |
| - | -Next, he leaves the rucksack unattended (the object is classified //unattended// if the distance between it and its owner is greater than 3 m) | + | |
| - | -Finally, the man disappears and the luggage rest unattended (possible bomb planting) | + | |
