, contextualization is the process of identifying the data relevant to an entity (e.g., a person or a city) 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 (via filtering, aggregation, and inference) 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 (Yavari et al.).

Usage

The main usage of "contextualisation" is in improving the process of data: :Reduce the amount of data: Contextualisation has the potential to reduce the amount of data based on the interests from applications/services/users. Contextualisation can improve the scalability and efficiency of data process, query, delivery by excluding irrelevant data. :As an example, ConTaaS facilitates contextualisation of the data for IoT applications and could improve the processing for large-scale IoT applications from various
