Semantic relations in bilingual lexicons
ACM Transactions on Speech and Language Processing, 2008Bilingual 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.

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.

A Semantics for Relational Programming
1992This paper presents an elementary model of relational programming as a generalisation of functional programming. We present well-known models of features of functional programming and show one way that they generalise to the relational case. This is achieved by giving a uniform construction of a category of types and relations from a category of types ...

Relation-based semantics for concurrency
Information Sciences, 1993``Despite several decades of research, capturing the semantics of concurrent programs in a crisp and tractable fashion remains a formidable challenge''. With this ambitious goal the authors initiate their quest towards the clean and manageable concurrency semantics many have searched for before with more or less success.

Relational Semantics and Domain Semantics for Epistemic Modals
Journal of Philosophical Logic, 2016The 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 ...

Relational Scaling in Relational Semantic Systems
2009In 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 ...

On the semantics of the relational data model
Proceedings of the 1975 ACM SIGMOD international conference on Management of data - SIGMOD '75, 1975The relational model for data base organization introduced clearly defined basic algebraic concepts whose properties are well understood. As a consequence, questions of a semantic nature arise. Due to the mathematical nature of the relational model, these questions cannot be answered completely by it.

On the Semantic Relation of Z and HOL
1998We 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.

Geographical Expression of Semantic Relations
2011 Seventh International Conference on Semantics, Knowledge and Grids, 2011This 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, 2002A 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.
