- Abstract:
-
To ensure that the extraction of uncertain information expressed in the form of "intervals" is focused, it is necessary to extract the corresponding attribute (object) interval set for the object (attribute) set. By introducing two thresholds from the fuzzy context, the unilateral interval set is combined with the classical semiconcept to extract the corresponding object (attribute) interval set for the attribute(object) set, and thereby the interval set extent-set intent(set extent-interval set intent)(ISE-SI (SE-ISI)) type partially-known fuzzy semiconcept is proposed. All ISE-SI (SE-ISI) type partially-known fuzzy semiconcepts form a lattice, and the algorithm based on lattice search for all ISE-SI (SE-ISI) type partially-known fuzzy semiconcepts is given. The multiple advantages of these two knowledge representation forms are demonstrated by comparing them with existing achievements. The results obtained in this paper have the advantages of broad applicability and strong practical application in knowledge representation and extraction methods.
