For given context-specific CLP model, all model features' MFs are adapted using linear and nonlinear transformation functions to three other contexts, and initial model accuracies, [RMSE.sub.CA-L] (where CA-L represents the context adapted CLP model using linear adaptation) and [RMSE.sub.CA-NL] (where CA-NL represents the context adapted CLP model using nonlinear adaptation), respectively, are established.
In order to improve the effectiveness of the optimization process required for determining the parameters of the piecewise linear transformation function with limited data from new contexts, the number of split points is kept to five points, as setting a higher number will have required increased amount of data and on the other hand setting a lower number will reduce the nonlinearity of the function.
Furthermore, a support for the Web service adaptation according to the context is required.
Nevertheless, BPEL neither supports dynamic changes , nor does it offer a support for the dynamic adaptation of the orchestration logic according to the context , .
In this paper, we first model the temporal correlations between user contexts with a heterogeneous Markov model and then formalize the context-privacy problem for smartphones to an optimization problem followed with correctness proof.
However, these techniques do not protect privacy against adversaries who have the knowledge of the temporal correlations between contexts. Moreover, the anonymity-based approaches do not readily imply privacy sometimes.
There is no unified standard for the classification of the context. Different researchers proposed different partition methods based on their own research backgrounds, applications, and research requirements.
We analyzed the context information which maybe produced in the new networking environment and the processes of service registration, service discovery, service selection, and service composition based on the needs of the user under the Internet of Things and defined the context information as the environment context information, the device context information, the user context information, and the calculation context information.
The proper architectural support is an indispensible foundation for the gathering, modelling, storing, and distributing of context data.
Early in 2001, a noticeable example framework named Context Toolkit was developed .
