  12. 12. Vous pouvez constater que votre consommation d’électricité a été moins élevée en moyenne cette année que l’année dernière. Pourtant la température a été en moyenne moins élevée (- 1.6°C par rapport à l’année dernière), ce qui a pu augmenter votre consommation de chauffage. La raison de cette diminution est donc certainement due à une utilisation moins fréquente et plus économe de vos équipements électriques que l’année dernière. You can notice that your electricity consumption has been less high on average this year than last year. However, the temperature has been less high on average (- 1.6°C compared to last year), that could have increased your electricity consumption dedicated to heating. This decrease is therefore certainly due to a less frequent and and more energy-efficient use of your electric appliances than last year.

  13. 13. Variations You can notice that your electricity consumption has been higher on average this year than last year. Considering that the temperature has been less high on average (- 1.6°C compared to last year), this could have increased your electricity consumption dedicated to heating. You can notice that your electricity consumption has been higher on average this year than last year. This increase is certainly due to a more frequent and less energy-efficient use of your electric appliances than last year.

  27. 27. Reasoning & Formulae • How to compute a formula in OWL ? - • computation in advance annotations on properties What if a formula depends on inferred facts ? The Energy Management Adviser at Electricité De France - ISWC 2013 vendredi 25 octobre 13
  28. 28. Special Situations • Not all the tips are valid for every customers e.g. : Do not tell elderly customers to reduce their home temperature • Define a new ontology vs Complicate the existent one • A SPARQL query used to subtract inaplicable tips The Energy Management Adviser at Electricité De France - ISWC 2013 vendredi 25 octobre 13

  33. 33. Avoiding Nominals • As soon as assertions describing a customer change, the ontology hierarchy has to be recomputed S ⊑ ∃ hasTip.{c1} • ∃ electricConsumption.{higher} We use ‘simulated nominal class’ instead ∃ isTipOf.S ⊑ C1 ∃ electricConsumption.Higher higher : Higher The Energy Management Adviser at Electricité De France - ISWC 2013 vendredi 25 octobre 13
