Controlled Natural Language Generation from a Multilingual FrameNet-based Grammar
This paper presents a currently bilingual but potentially multilingual
FrameNet-based grammar library implemented in Grammatical Framework. The
contribution of this paper is two-fold. First, it offers a methodological
approach to automatically generate the grammar based on semantico-syntactic
valence patterns extracted from FrameNet-annotated corpora. Second, it provides
a proof of concept for two use cases illustrating how the acquired multilingual
grammar can be exploited in different CNL applications in the domains of arts
and tourism
CHR Grammars
A grammar formalism based upon CHR is proposed analogously to the way
Definite Clause Grammars are defined and implemented on top of Prolog. These
grammars execute as robust bottom-up parsers with an inherent treatment of
ambiguity and a high flexibility to model various linguistic phenomena. The
formalism extends previous logic programming based grammars with a form of
context-sensitive rules and the possibility to include extra-grammatical
hypotheses in both head and body of grammar rules. Among the applications are
straightforward implementations of Assumption Grammars and abduction under
integrity constraints for language analysis. CHR grammars appear as a powerful
tool for specification and implementation of language processors and may be
proposed as a new standard for bottom-up grammars in logic programming.

A CNL for Contract-Oriented Diagrams
We present a first step towards a framework for defining and manipulating
normative documents or contracts described as Contract-Oriented (C-O) Diagrams.
These diagrams provide a visual representation for such texts, giving the
possibility to express a signatory's obligations, permissions and prohibitions,
with or without timing constraints, as well as the penalties resulting from the
non-fulfilment of a contract. This work presents a CNL for verbalising C-O
Diagrams, a web-based tool allowing editing in this CNL, and another for
visualising and manipulating the diagrams interactively. We then show how these
proof-of-concept tools can be used by applying them to a small example
Papers on predicative constructions : Proceedings of the workshop on secundary predication, October 16-17, 2000, Berlin
This volume presents a collection of papers touching on various issues concerning the syntax and semantics of predicative constructions.
A hot topic in the study of predicative copula constructions, with direct implications for the treatment of he (how many he's do we need?), and wider implications for the theories of predication, event-based semantics and aspect, is the nature and source of the situation argument. Closer examination of copula-less predications is becoming increasingly relevant to all these issues, as is clearly illustrated by the present collection
Towards a constructional approach to discourse-level phenomena : the case of the Spanish interpersonal epistemic stance construction
This study contributes to a better understanding of how constructional models can be applied to discourse-level phenomena, and constitute a valuable complementation to previous grammaticalization accounts of pragmatic markers. The case study that is presented concerns the recent development of the interpersonal epistemic stance construction in Spanish. The central argument is that the expanding use of sabes as a pragmatic marker can best be fully understood by taking into account the composite network of related expressions which Spanish speakers have at their disposal when performing a particular speech act. The diachronic analysis is documented with spoken corpus examples collected in recent decades, and is mainly informed by frequency data measuring the productivity, as well as formal properties of the construction and its instances
Transforming specifications of observable behaviour into programs
A methodology for deriving programs from specifications of observable
behaviour is described. The class of processes to which this methodology
is applicable includes those whose state changes are fully definable by labelled
transition systems, for example communicating processes without
internal state changes. A logic program representation of such labelled
transition systems is proposed, interpreters based on path searching techniques
are defined, and the use of partial evaluation techniques to derive
the executable programs is described
