Faisal Razzak's PhD presentation at Politecnico di Torino focuses on the integration of semantic web technologies into smart environments, specifically addressing user-centered goals in energy management. The research emphasizes the development of a semantic energy information publishing framework and evaluates the effectiveness of device control, enforcement, and energy optimization techniques. The findings suggest that efficient enforcement and evaluation mechanisms can significantly enhance the programming and monitoring of personal environments.

- 5. Motivation IST Advisory group published a draft titled „Ambient Intelligence: From vision to reality‟. In order to build intelligence, we need to innovate abstract concepts and models to address human centric expressions of personal style. (2003) A series of workshops and interviews, concluded that designers work top-down and like to start from abstract descriptions. (2008) The need for abstract models to address human centric expressions 1) Ducatel, K., M. Bogdanowicz, F. Scapolo, J. Leijten, and J. C. Burgelman. "Ambient intelligence: From vision to reality."

- 6. The Issues The issue of Device centric vision? The question of Enforcement? The question of Evaluation (monitoring)? Can there be a unified model? 6 Presentation @DAUIN, Politecnico di Razzak Torino, Italy
- 7. Domotic Effects Framework Domotic Effects model Human intelligible state and goal. • It provides AMI designers with an abstraction layer that enables defining generic goals inside the environment, in a declarative way. • The high-level nature allows the residents to program their personal, office or work spaces as they see fit. • Simple Effect (SE) and DogEffects Ontology Complex Effect (CE) 7 Presentation @DAUIN, Politecnico di Razzak Torino, Italy

- 16. Is it Applicable? -- Evaluation Evaluation In one experiment, results showed that for an iteration the presence of 1500 CEs with the maximum level of 177 can be evaluated in 118 ms (averaged over 150 times). In another experiment results showed that for a single device change, the presence of 1400 CEs with the maximum level of 272 can be evaluated in 258 ms. The goal was in less than 1 or 2 seconds. 18 Presentation @DAUIN, Politecnico di Razzak Torino, Italy
- 17. Is it Applicable? -- Enforcement Six use cases Secure Home Home Illumination Morning Wakeup Isolated Kitchen Room Illumination Air Passage across Home All possible combination of use cases, i.e., 64 In summary, the implemented enforcement module was able to resolve to devices in less than 100 ms. The goal was in less than 1 or 2 seconds. 19 Presentation @DAUIN, Politecnico di Razzak Torino, Italy
- 18. An enforcement with minimal power consumption Formulation Results Compared against Enumeration approach. For 90% of iterations the result of power consumption was better or at least equal (in case of minimal). The heuristic solution time was between 1 to 2 seconds for all cases. Even for cases with more than 100,000 (enumerated) 20 solutions. Presentation @DAUIN, Razzak Politecnico di Torino, Italy

Semantics comes from context (User and current settings). 24 Presentation @DAUIN, Politecnico di Razzak Torino, Italy
