Ontology-based framework model of context perception application platform

Abstract

An ontology-based framework model of a context perception application platform, which is characterized in that a context information acquisition layer collects signals from a sensor to require original context information; a context information amalgamation layer requires the original context information from the context information acquisition layer and requires inferior context information by preliminary abstracting and processing; a context information management layer requires the inferior context information from the context information amalgamation layer and requires advanced context information by using Ontology and an inference mechanism; and a context application layer unifies each context item and each context abstract status into modeling context objects on the application layer surface and offers an applied view which is attributes and the correlated operations of a group of service levels. The model enables context perception application developers to embedding the service operations in to the application thereof to realize the acquisition and the logical judgment of context or status by utilizing a group of general service operations which are applicable to all the context or status information to screen specific context isomerism.

Description

technical field [0001] The invention relates to a context-aware application platform framework model, in particular to an ontology-based context-aware application platform framework model. Background technique [0002] With the continuous popularization and development of computers and the development of wireless communication technology, various mobile devices have increasingly entered people's lives, and computing has also been integrated into people's lives. Ubiquitous computing is a new change in the computing model after mainframe computing and desktop computing. Its proposal has changed the way people use computing resources and transformed computer-centric computing into human-centered computing. Its concept is to create One of the key theories of a new human-centered information service environment is context awareness, which organically combines various computing resources, information services, and people through context awareness to automatically perform user task...

AI Technical Summary

Problems solved by technology

It can be seen from the above that Context ToolKit supports the acquisition, interpretation and integration of context, and provides persistent management of context information, supports distributed communication and context information acquisition, and has certain support for the application of context history, but its support mechanism for shared context and the model is ambiguous
