- ZeitschriftenartikelAccentuating Features of Description Logics in High-Level Interpretations of Hand-Drawn Sketches(KI - Künstliche Intelligenz: Vol. 33, No. 3, 2019) Abdelghaffar, Nashwa M.; Abdelfattah, Ahmed M. H.; Taha, Azza A.; Khamis, Soheir M.We propose an ontology-based approach to interpret hand-drawn sketches, originating from empirical results of experiments with human participants. The approach combines qualitative features of the sequence of sketch strokes with a high-level knowledge, and accentuates the potential effectiveness of interpretation via description logics. The results of an implementation, along with explanations, are presented to show how to extract the semantics of hand-drawn sketches of four object categories.
- ZeitschriftenartikelSemantics of Analogies from a Logical Perspective(KI - Künstliche Intelligenz: Vol. 33, No. 3, 2019) Abdelfattah, Ahmed M. H.; Krumnack, UlfA number of different approaches to model analogies and analogical reasoning in AI have been proposed, applying different knowledge representation and mapping strategies. Nevertheless, analogies still seem to be hard to grasp from a formal perspective, with no known treatment in the literature of, in particular, their formal semantics, though the empirical treatments involving human subjects are abundant. In this paper we present a framework that allows to analyze the syntax and the semantics of analogies in a universal logic-based setting without committing ourselves to a specific type of logic. We show that the syntactic process of analogy-making by finding a generalization can be given a sensible interpretation on the semantic level based on the theory of institutions . We then apply these ideas by considering a framework of analogy-making that is based on classical first-order logic.
