Experts in scientific fields routinely operate under less-than-ideal conditions. We present a deployed data analysis system for cosmogenic isotope dating, a domain that is fraught with difficult automation issues. First, experts must work with a huge array of possible parameters. Our system ACE handles this issue by pushing the bounds of software flexibility. Furthermore, isotope dating experts...

Vagueness is a common human knowledge and linguistic phenomenon, typically manifested by predicates that lack clear applicability conditions and boundaries such as High, Expert or Bad. In the context of ontologies and semantic data, the usage of such predicates within ontology element definitions (classes, relations etc.) can hamper the latter’s quality, primarily in terms of shareability and m...

Soft set theory, proposed by Molodtsov has been regarded as an effective mathematical tool to deal with uncertainties. Vague set is a set of objects, each of which has a grade of membership whose value is a continuous subinterval of [0, 1]. Such a set is characterized by a truth-membership function and a falsemembership function. Thus, a vague set is actually a form of fuzzy set, albeit a more ...
