Querying XML data is a well-explored topic thanks to powerful query languages such as XPath and XQuery. Both were designed to support the evaluation of binary predicates, which can be proven to be a limited approach to effective querying of XML data. In this paper, a fuzzy extension of the XPath query language is proposed. Its goal is to achieve more flexible querying through vague queries, whi...

Abstract Natural language does not express all connectives definable in classical logic as simple lexical items. Coordination English is expressed by conjunction and , disjunction or negated nor . Other languages pattern similarly. Non-lexicalized are typically compositionally: English, combining negation ( both ). This surprising: if $$\wedge $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math...

A conjunction T ties an implication operator A if the identity A(a,A(b, z)) = A(T (a, b), z) holds [A.A. Abdel-Hamid, N.N. Morsi, Associatively tied implications, Fuzzy Sets and Systems 136 (2003) 291–311]. We study the class of tied adjointness algebras (which are five-connective algebras on two partially ordered sets), in which the implications are tied by triangular norms. This class contain...

This article shows how the automatic disambiguation of discourse connectives can improve Statistical Machine Translation (SMT) from English to French. Connectives are firstly disambiguated in terms of the discourse relation they signal between segments. Several classifiers trained using syntactic and semantic features reach stateof-the-art performance, with F1 scores of 0.6 to 0.8 over thirteen...
