Embodiment Construction

[0018] Such as figure 1 As shown, the context-aware system driven by Pragmatic Web includes three layers: context acquisition layer, context middleware layer and context service layer. The context acquisition layer includes the acquisition of external context and internal context. The external context (also known as the low-level context) usually describes the state of the physical environment, such as location, temperature, and time, which can be directly obtained through physical sensors, logical sensors, and other cognitive devices. The internal context (also known as the high-level context) is used to describe the user status, such as work status, personal events, communication context and the user's emotional state, the web pages accessed by the user captured by the network capture technology, the files transmitted or transmitted through the network medium Anything in is a valid source of internal context. Since the user's static information is not suitable for the cont...

Abstract

Aimed at the problem that a traditional semantic net body and a context sensing system are not suitable for processing dynamic knowledge in the real world, a context sensing system driven by a pragmatic web on the basis of the advantages of the pragmatic web in expressing the dynamic knowledge is invented. According to the context sensing system driven by the pragmatic web, a context sensing system framework driven by the pragmatic web is developed, an efficient and novel context acquisition technology is adopted, the true intention of a user can be more accurately captured, and on this basis, a high-level context with a decision-making capability is obtained through inference, and finally a 'user-centered' personalized recommendation service is achieved through a context sensing service discovery method based on an intelligent agent.

Description

technical field [0001] The invention relates to a context awareness system, in particular to a context awareness system driven by a pragmatic web. Background technique [0002] The Semantic Web is an essential change of the World Wide Web. The information on the Semantic Web is endowed with clear meanings, which facilitates the collaboration between humans and computers. However, the traditional Semantic Web ontology can only represent static and absolute knowledge, which is not suitable for Handle knowledge of dynamic changes in the real world. Aiming at the shortcomings of the traditional Semantic Web ontology in realizing dynamic knowledge management and control, the concept of Context was introduced, and then developed into the next-generation Web: Pragmatic Web. Most of the current context-aware system architectures are static, and the research perspectives mainly include ontology-based and semantic-based Web technologies, etc., which cannot combine user-specific situa...
