摘要
A computer-implemented method for supporting detection of a sign of cognitive decline is disclosed. In the method, a reference set of conversational data recorded for an individual and one or more sets of conversational data recorded for the individual on different days from the reference set are obtained. The method includes evaluating at least a temporal separation between conversations corresponding to the reference set and each of the one or more sets of the conversational data determine a value of the temporal separation. The method also includes determining topic similarity between the reference set and each of the one or more sets of the conversational data. A feature is generated for the individual based, at least in part, on relationship between the value and the topic similarity, and the computed feature is then sent as a message corresponding to a diagnosis.
