The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a segment of a text or speech, relatively complete in thought, in which the sense and meaning of each of its words (phrases) or quoted expressions is set forth in the most concrete and exact way.

Outside of the context (“taken out of context”) in which a quotation is linked stylistically and semantically, it can take on another, even opposite, meaning. In literature the context deter-mines the concrete content, the expressiveness, and the stylistic nuances not only of individual words, phrases, and utterances but of the different artistic methods as well (including poetic figures and verse rhythms). The context also determines the stylistic choice of words (for example, A. Blok wrote a note about the character of Gaetan while he was working on his play The Rose and the Cross; “not eyes but orbs, not hair but curls, not mouth but lips”). Breaking the context destroys the artistic unity of a text and the artistic image itself (it is impossible, for example, to catch the irony of something outside of its context). Placing something out of context, however, is sometimes used for stylistic effects, as in the case of parody.

This step is crucial especially in order to identify and to model the contextual information pertinent for services, to determine the current context.
In order to use the contextual information in an adequate manner, we need to define a context model for the representation of the service context called: CM4S (Context Model for Services).

Through a lot of experiments, we find that the decision tree classification algorithm and the wrapper feature selection method based on the genetic algorithm have achieved good classification results in the context information for the Internet of Things.
