Semantic Lexicons: the Cornerstone for Lexical Choice in Natural Language Generation
- …In this paper, we address the issue of integrating semantic lexicons into NLG systems and argue that the problem of lexical choice in generation can be approached only by such an integration. We take the approach of Generatire Lexicon Theory (GLT) (Pustejovsky, 1991, 1994c) which provides a system i…

The computational lexical semantics of syntagmatic relations
- …In this paper, we address the issue of syntagmatic expressions from a computational lexical semantic perspective. From a representational viewpoint, we argue for a hybrid approach combining linguistic and conceptual paradigms, in order to account for the continuum we find in natural languages from f…

Morpho-semantics and Constructive Derivational Morphology: a Transcategorial Approach to Lexical Rules
- …In this report, we present the automatic acquisition of a lexicon involving the use of morphosemantic lexical rules on a core lexicon which was acquired semi-automatically. The process of large-scale dictionary making, as we de ned it to build Spanlex, a Spanish lexicon, for Mikrokosmos, amachine tr…

De-Constraining Text Generation
- …We argue that .the current, predominantly task-oriented, approaches to modularizing text 'generation, While plausible and useful conceptually, set up spurious conceptual and operational constraints. We propose a data-driven approach to modularization and illustrate how it eliminates.…

Long Time No See: Overt Semantics for Machine Translation
- …In this paper, we show how a computational semantic approach is best fitted to address the translation of highly isolating languages. We use Chinese as an example and present the overall process of translation from Chinese to English, within the framework of Knowledge-Based Machine Translation (KBMT…

Constraints in Computational Semantics
- …Research reported in this paper a) extends the familiar notions of constraints and preferences in computational semantic analysis and generation; b) adapts constraint satisfaction techniques to the requirements of natural language processing; and c) combines i) largescale static knowledge sources (g…

Breaking Down Barriers: The Mikrokosmos Generator
- …We argue that the modularization of text generation into separate tasks, as currently practiced, sets up unneeded barriers to the generation task. We propose a new modularity based on natural linguistic phenomena and overview how it is implemented in the Mikrokosmos text generator. 1 Introduction T…

From Submit to Submitted via Submission: On Lexical Rules in Large-Scale Lexicon Acquisition
- …This paper deals with the discovery, representation, and use of lexical rules (LRs) during large-scale semi-automatic computational lexicon acquisition. The analysis is based on a set of LRs implemented and tested on the basis of Spanish and English business- and finance-related corpora. We show tha…

An Overt Semantics with a Machine-guided Approach for Robust LKBs
- …In this paper, we report on our experience in build~ ing computational semantic lexicons for use in NLP applications In a machine-guided approach, the computer induces part of the semantic knowledge to be acquired by an acquirer An overt semantics can help predict the syntactic behavior of words By …
