Contextualization (computer science)
In computer science, contextualization is the process of identifying the data relevant to an entity based on the entity's contextual information.
Definition
Context or contextual information is any information about any entity that can be used to effectively reduce the amount of reasoning required for decision making within the scope of a specific application. Contextualisation is then the process of identifying the data relevant to an entity based on the entity's contextual information. Contextualisation excludes irrelevant data from consideration and has the potential to reduce data from several aspects including volume, velocity, and variety in large-scale data intensive applications.Usage
The main usage of "contextualisation" is in improving the process of data:Example domains
- Object-oriented programming: Contextualization consists, at object creation time, to provide adequate initialization parameters to a class constructor.
- Virtualization: Contextualization permits, at the end of VM instantiation, to set or override VM data having unknown or default values at the time of creation of the Live CD, typically hostname, IP address,.ssh/authorized_keys,...
