||Evolution of Internet is very fast since 1980s. In the early age, there are some devices which can connect each other by internet. But now, there are hundreds of thousands of devices which can connect each other by internet. With the evolution of device technology, Internet of Thing will be a trend. How to identify the meaningful information from these devices? And how to use the information to provide services? These are part of the big issues of Internet of Thing. |
In our opinion, we should manage the information by systematic methodology. Reference others’ research, the information’s lifecycle include four stages, they are Context Acquisition, Context Modeling, Context Reasoning, and Context Distribution. If we want to well mange the information and provide the service to users, we should do the four stages.
In this research, we focus on Context Modeling part. We analyze the Context Definition to find the properties on it, and build the Context Metamodel. We also propose a methodology to map sensed data to Context.
