Relational Semantics

1997
Abstract Having solved the completeness problem, the algebraic semantics, introduced in the previous chapter, deprives us, however, of that transparent interpretation of logical connectives which made it possible to construct models for formulas by analyzing step by step their subformulas and adding new points, if necessary.

Semantic relations in bilingual lexicons

ACM Transactions on Speech and Language Processing, 2008
Bilingual lexicons, essential to many NLP applications, can be constructed automatically on the basis of parallel or comparable corpora. In this article, we make two contributions to their induction from comparable corpora. The first one concerns the creation of these lexicons.

Geographical Expression of Semantic Relations

2011 Seventh International Conference on Semantics, Knowledge and Grids, 2011
This paper presents a method of how to produce a calculate and express spatial relations by a set of parameters. A new set of parameters more easily to understand and use is proposed based on two semantic meanings. Also the Voronoi diagram's application in neighbor relations is discussed.

Update semantics for multilevel relations

[1990] Proceedings of the Sixth Annual Computer Security Applications Conference, 2002
A formal operational semantics is given for update operations on multilevel relations, i.e., relations in which individual data elements are classified at different levels. For this purpose, the familiar INSERT, UPDATE and DELETE operations of SQL are suitably generalized to cope with polyinstantiation.

On the Semantic Relation of Z and HOL

1998
We investigate the relation between the semantic models of Z, as proposed by the Z draft standard, and of the polymorphic version of higher-order logic that is the basis for proof systems such as HOL and Isabelle/HOL. Disregarding the names in schema types, the type models of the two systems can be identified up to isomorphism.

Refer-to-as Relations as Semantic Knowledge

Proceedings of the AAAI Conference on Artificial Intelligence, 2015
We study Refer-to-as relations as a new type of semanticknowledge. Compared to the much studied Is-a relation,which concerns factual taxonomy knowledge, Refer-to-as relationsaim to address pragmatic semantic knowledge. Forexample, a “penguin” is a “bird” from a taxonomy point ofview, but people rarely refer to a “penguin” as a “bird ...

Relational Scaling in Relational Semantic Systems

2009
In this paper two developments in Conceptual Knowledge Processing are combined, namely Contextual Logic introduced by Rudolf Wille and Temporal Concept Analysis introduced by the author. The basic structures connecting both theories are Relational Semantic Systems (RSS), each consisting of conceptual scales and a Relational Data Systems (RDS) for the ...

Relational Semantics and Domain Semantics for Epistemic Modals

Journal of Philosophical Logic, 2016
The standard account of modal expressions in natural language analyzes them as quantifiers over a set of possible worlds determined by the evaluation world and an accessibility relation. A number of authors have recently argued for an alternative account according to which modals are analyzed as quantifying over a domain of possible worlds that is ...

Relation Elements for the Semantic Web

2004
The investigation into the intrinsic nature of relations has led to the development of the Relation Element theory. At present, there is no significant initiative to comprehensively describe the intrinsic nature of relations in ontological representations for the Semantic Web.

Semantic field and accessibility relations

KES'2000. Fourth International Conference on Knowledge-Based Intelligent Engineering Systems and Allied Technologies. Proceedings (Cat. No.00TH8516), 2002
We give a fundamental definition of semantic fields and explain how accessibility relations can be related to semantic fields. The semantic field is then related to set theory, laws and facts, and Scott-Montague models.
