We present a design for a new electronic lexicon of Czech discourse connectives. The data format and the annotation scheme are based on a study of similar existing resources, and we discuss arguments for choosing the data structure and selecting features of the lexicon entries. A special attention is paid to a consistent encoding of both primary and secondary connectives. The data itself comes ...

Temporal–contrastive discourse connectives (although, while, since, etc.) signal various types of relations between clauses such as temporal, contrast, concession and cause. They are often ambiguous and therefore difficult to translate from one language to another. We discuss several new and translation-oriented experiments for the disambiguation of a specific subset of discourse connectives in...

In this paper we describe the (annotation) tools underlying two automatic techniques to analyse the meaning and use of backward causal connectives in large Dutch newspaper corpora. With the help of these techniques, Latent Semantic Analysis and Thematic Text Analysis, the contexts of more than 14,000 connectives were studied. We will focus here on the methods of analysis and on the fairly strai...

Abstract Language employs various coordinators to connect propositions, a subset of which are “logical” in nature and thus analogous the truth operators formal logic. We here focus on two linguistic connectives their negations: conjunction (inclusive) disjunction or . Linguistic exhibit truth-conditional component as part meaning (their semantics), but use context can give rise implicatures pre...

This paper describes a Natural language processing system developed for automatic identification of explicit connectives, its sense and arguments. Prior work has shown that the difference in usage of connectives across corpora affects the cross domain connective identification task negatively. Hence the development of domain specific discourse parser has become indispensable. Here, we present a...

This contribution explores the subgroup of text structuring expressions with the form preposition + demonstrative pronoun, thus it is devoted to an aspect of the interaction of coreference relations and relations signaled by discourse connectives (DCs) in a text. The demonstrative pronoun typically signals a referential link to an antecedent, whereas the whole expression can, but does not have ...

In this paper we define two logics, KLn and BLn, and present resolutionbased proof methods for both. KLn is a temporal logic of knowledge. Thus, in addition to the usual connectives of linear discrete temporal logic, it contains a set of unary modal connectives for representing the knowledge possessed by agents. The logic BLn is somewhat similar: it is a temporal logic that contains connectives...

AbsikactFuzzy connectives use to be assumed associative. In this way, key operational difficulties are solved by means of a single binary operator. In this paper we point out that the main property in order to assure operativeness should be recurszveness, which is weaker than associativity. If calculus can be obtained by means of a recursive application of a sequence of binary connectives, we s...

This paper aims to rehabilitate the idea that there are conditional connectives in the logical forms of natural language. I propose to adopt a connective with a truth-value gap semantics inspired by Belnap (1970), such that conditionals only have a truth-value if their antecedent is true. Together with the assumption that quantifiers select worlds for which their scope is defined, this predicts...

Contemporary students of logic tend to think of the logic of the connectives as the most basic area of the subject, which can then be extended with a logic of quantifiers. Historically, however, the logic of the quantifiers, in the form of the Aristotelian theory of the syllogism, came first. Truth conditions for negation, conjunction, and disjunction were well understood in ancient times, thou...
