Olfactory Cognitive Diagnosis

An olfactory-based cognitive system is implemented by receiving a request from a user, the request including one or more attributes, wherein the one or more attributes include at least olfactory-sensed data and an identification of the olfactometer or electronic nose utilized to gather the olfactory-sensed data. A set of candidate recommendations is generated utilizing the one or more attributes from data sources. A confidence score is generated for each candidate recommendation in the set of candidate recommendations indicating a confidence that the corresponding candidate recommendation is valid to address the request. Each candidate recommendation in the set of candidate recommendations is ranked according to its respective confidence scores. The ranked listing of candidate recommendations is presented to the user for use in addressing the request.
