It is well-known that focusing striates a sequent derivation into phases of like polarity where each phase can be seen as inferring a synthetic connective. We present a sequent calculus of synthetic connectives based on neutral proof patterns, which are a syntactic normal form for such connectives. Different focusing strategies arise from different polarisations and arrangements of synthetic in...
Discourse connectives can be analyzed as encoding predicate-argument relations whose arguments derive from the interpretation of discourse units. These arguments can be anaphoric or structural. Although structural arguments can be encoded in a parse tree, anaphoric arguments must be resolved by other means. A study of nine connectives, annotating the location, size, and syntactic type of their ...
We describe our initial efforts towards developing a large-scale corpus of Hindi texts annotated with discourse relations. Adopting the lexically grounded approach of the Penn Discourse Treebank (PDTB), we present a preliminary analysis of discourse connectives in a small corpus. We describe how discourse connectives are represented in the sentence-level dependency annotation in Hindi, and disc...

The positioning of sentential connectives in Chinese complex sentences is more flexible than their counterparts in English. Sentential connectives in Chinese can be placed in three sensitive positions: clause-initial, predicate-initial, and clause-final positions. Due to the co-existence of prepositions and postpositions in the language, sentential connectives can be placed in both clause-initi...
Three-valued logics arise in several fields of computer science, both inspired by concrete problems (such as in the management of the null value in databases) and theoretical considerations. Several three-valued logics have been defined. They differ by their choice of basic connectives, hence also from a syntactic and proof-theoretic point of view. Different interpretations of the third truth v...
This study focuses on the impact of linguistic markers of coherence on the comprehension of expository discourse. The impact of such markers on comprehension (i.e. off-line) is a highly controversial topic in current studies, especially for connectives for which a facilitating as well as an interfering role has been demonstrated. As a matter of fact, it seems that connectives facilitate the com...
We present the first effort towards producing an Arabic Discourse Treebank, a news corpus where all discourse connectives are identified and annotated with the discourse relations they convey as well as with the two arguments they relate. We discuss our collection of Arabic discourse connectives as well as principles for identifying and annotating them in context, taking into account properties...
In this paper we compare grammatical inference in the context of simple and of mixed Lambek systems. Simple Lambek systems are obtained by taking the logic of residuation for a family of multiplicative connectives =; ; n, together with a package of structural postulates characterizing the resource management properties of the connective. Diierent choices for Associativity and Commutativity yiel...
