If crime is not scale invariant, this implies that there are different processes at each level, or that there is some form of hierarchical arrangement where higher level contexts help shape the outcomes of lower level processes (e.g., street segments provide a context that moderates the address level dynamics of crime).
Detail of each layer is described sufficiently to insight the process of context generation from low level contextual data up to high level context reporting scheme in a given pervasive environment.
Naïve Bayesian classifiers are used to recognize high level contexts in terms of their constituent atomic context elements involving uncertainty.
Context-aware applications should be able to acquire raw data from sensors, make high-level context information, recognize the user's situation, and adapt behavior of the system.
Traditionally, location systems have been built bottom-up beginning with low-level sensors and adding layers up to high-level context.
This allows the high-level context and causal knowledge of behavioural interactions between individual plants and insects, and consequent ecological interactions between plant and insect populations, to be discovered.
Also, another plan is to combine other known high-level context information with the proposed algorithm to get a more accurate object segmentation result.
This entails the analysis and estimation of what is going on in the surrounding environment in the context of smart sustainable cities. Accordingly, for a context-aware application or system to be able to infer high-level context abstraction based on the interpretation of and reasoning on context information, it is first necessary to acquire low-level data from physical sensors (and other sources).
The context information acquisition module (CIAM), as shown in Figure 2, acquires low-level data from the IP router and the network interfaces, and transforms them to the proper form (i.e., high-level context information) in order to be utilized as input for the SAC and Capacity Distribution modules as well as for the Relay module (cf. Section 6).
The applications thus receive both low-level as well as high-level context information.
