“…Currently, many researchers have put forward their own definitions of context. Li [13] gave a relatively general context definition. He thought that context is the environment itself and the explicit or implicit state (including historical state) information of various entities in the environment, where the entities may be physical entities, such as people and locations, and may also be virtual entities, such as softwares, programs and networks.…”

With the rapid development of Internet, Internetware has attracted a lot of attention as a new promising computing paradigm. Internetware can evolve continuously during runtime with the changes of its environment, thus to achieve higher software performance and customer satisfaction. So it is important to develop effective Internetware context awareness technologies. In this paper, we propose a novel multilayered context awareness technology. First, we build a three-layered architecture for Internetware to avoid disorderly context information transmission. Then, we utilize the ontology model language OWL to formalize Internetware context, to form a unified understanding of context information in the whole Internetware system. Finally, an extensible context management framework is proposed to drive different components in the Internetware system to access and operate related context information. In this proposed context management framework, we utilize the publish/subscribe mechanism to distribute context information and employ ontology libraries for context persistence. With these mechanisms, context awareness technology can facilitate Internetware evolution effectively.

In this paper, the project of context awareness information is introduced into the traditional collaborative filtering algorithm based on item, modeling by context awareness, put forward a kind of combination of context-aware computing collaborative filtering algorithm. The algorithm of the project context similarity calculation of similar fusion to the project, and then preference prediction and recommend using collaborative filtering algorithm, test the indicators of algorithm optimization, efficiency and accuracy of the proposed algorithm. IndexTerms-Collaborative filtering algorithm, context-aware computing, similarity degree.

“…Context-aware computing takes in charge of managing, coordinating and scheduling the elements in the computing environment including device, context and physical environment building the interoperability of entity objects and providing unified API for applications and development [2]. In this paperthe "context is defined to describ the physical environment and objects representation characterization information, such as time, location and task, and then to judge and decide what kind of service the user object need.…”

with the development of e-commerce, it has become a study focus as how to get mobile service timely and accurately, as well as how to realize the context information management of users. In this paper, it takes mobile tourism for example to classify and describe context information firstly ,then extract scene features to construct a quality restriction system and eventually build up a self-guided ontology-based mobile information management model for the context. It also cites West Lake Self-help guide as an example to verify the validity of above model in this paper
