| This service aims to assess the relative contribution of information sources in terms of situation awareness vis-a-vis a particular situation. This service enables analysts to determine the relative importance of information sources in terms of their current operational interests and to (perhaps) remove redundant sources. Note that the notion of 'importance' is not synonymous with the notion of trust. A trustworthy source may contribute very little information to a particular situation while a distrusted information source may provide valuable information. For example, if an information source is completely distrusted (has an associated trust level of 0), then we can infer that all assertions made from this source are false - this can clearly be of great value in some contexts. |
