1. Introduction. While vagueness and ambiguity have been opposed in the semantic domain (vagueness is often described as meaning underdetermination, ambiguity as meaning overdetermi-nation, see Fine 1975; moreover, vagueness is fundamentally a property of concepts, ambiguity a property of stimuli or expressions), Raffman has made the suggestion that within soritical series, borderline cases typ...

Increasingly sophisticated knowledge requires an inclusive knowledge representation that facilitates the integration of independently-generated information arising from different kind of efforts. The use of semantic web technologies addresses the reality of diverse interests on an ontology merging and supports knowledge discovery over that. Significant research efforts in the Semantic Web are r...

Abstract Artificial Intelligence (AI) pervades humanity in 2022, and it is notoriously difficult to understand how certain aspects of work. There a movement— Explainable (XAI)—to develop new methods for explaining the behaviours AI systems. We aim highlight one important philosophical significance XAI—it has role play elimination vagueness. To show this, consider that use what been labeled surv...

Interpretation clearly depends on context. Typically, context restricts the range of interpretation: thanks to context, ambiguity is resolved, reference is determined, and vagueness is constrained. This squib suggest that under certain very specific conditions, context can enlarge rather than restrict the extension of a predicate. The phenomenon in question is illustrated by the semantic contra...

The Abstract Much effort has been put into computational lexicons over tile years, and most systems give much room to (lexical) semantic data. However, in these systems, the effort put on tile study and representation of lexical items to express the umterlying continuum existing in 1) language vagueness and polysemy, and 2) language gaps and mismatches, has remained embryonic. A sense enumerati...

However, in these systems, the effort put on the study and representation of lexical items to express the underlying continuum existing in 1) language vagueness and polysemy, and 2) language gaps and mismatches, has remained embryonic.

My views on the semantic and pragmatic interpretation of natural language were influenced a lot by the works of Martin, Jeroen and Frank. What attracted me most is that although their work is always linguistically relevant, it still has a philosophical point to make. As a student (not in Amsterdam), I was already inspired a lot by their work on dynamics semantics, and by Veltman’s work on data ...

Description logics (DLs) and logic programs (LPs) are important representation languages for the Semantic Web. In this paper, we address an emerging problem in such languages, namely, the problem of evaluating ranked top-k queries. Specifically, we show how to compute the top-k answers in a datacomplexity tractable combination of DLs and LPs under vagueness.
