Abstract:
1. A computer-implemented method comprising: accessing, by a computing device, a certainty factor associated with a piece of multiple pieces of information that are each associated with a respective certainty factor, wherein the certainty factor associated with the piece of information provides an indication of certainty of that piece of information and is stored in a context store with the piece of information but is accessible from the context store separately from the piece of information, wherein the certainty factor is accessible to maintain the certainty factor by at least one of a context provider that established the certainty factor or another context provider, and wherein the certainty factor is accessible to obtain a value of the certainty factor by one or more context consumers that at least one of queries for the certainty factor or subscribes to changes of the certainty factor; accessing a decay rate associated with the piece of information, wherein each of the multiple pieces of information is associated with a respective decay rate; decreasing the certainty factor of the piece of information by applying the accessed decay rate to the certainty factor; and replacing the certainty factor of the piece of information with a decreased certainty factor.
