Experiment design and execution is a central activity in the natural sciences. The SeqER system provides a general architecture for the integration of automated planning techniques with a variety of domain knowledge in order to plan scientific experiments. These planning techniques include rule-based methods and, especially, the use of derivational analogy. Derivational analogy allows planning ...

Recent applications of Tree-Adjoining Grammar (TAG) to the domain of semantics as well as new attention to syntactic phenomena have given rise to increased interested in more expressive and complex multicomponent TAG formalisms (MCTAG). Although many constructions can be modeled using tree-local MCTAG (TL-MCTAG), certain applications require even more flexibility. In this paper we suggest a shi...

The general issue of derivational vs. representational approaches to syntax has received considerable attention throughout the history of generative grammar. Internal to the major derivational approach, transformational grammar, a related issue arises: are well-formedness conditions imposed specifically at the particular levels of representation made available in the theory, or are they imposed...

Morpheme frequency effects for derived words (e.g. an influence of the frequency of the base ‘‘dark” on responses to ‘‘darkness”) have been interpreted as evidence of morphemic representation. However, it has been s...

Minimalist grammars (MGs) constitute a mildly contextsensitive formalism when being equipped with a particular locality condition (LC), the shortest move condition. In this format MGs define the same class of derivable string languages as multiple context-free grammars (MCFGs). Adding another LC to MGs, the specifier island condition (SPIC), results in a proper subclass of derivable languages. ...

Events have been represented as part of the lexicon (Grimshaw 1990; Pustejovsky 1991), as part of argument structure (Davidson 1967; Higginbotham 1985; Kratzer 1994), in aspectual projections (Tenny 1994; Borer 1994; Travis 1991, 1994) and as a property of Feature Checking (van Hout 1996). We argue that the Feature Checking account defined on Event related projections captures morphological var...

In this work, we address the deciphering of semantic relations between terms in order to build structured terminologies. We study particularly the contribution of morphological clues. Among linguistic operations proposed by the morphology, we analyze affixation and suppletion. We show interpretative schemata emerging from morphologically formed lexemes and corresponding terminological relations...

The main goal of this paper is to argue for an approach to optimization in syntax that is not global (as is standardly assumed), but local, in the sense that syntactic optimization procedures can affect only small portions of syntactic structure. Local optimization presupposes harmonic serialism (rather than harmonic parallelism), i.e., a derivational organization of grammar. In line with this,...

Démonette is a derivational morphological network designed for the description of French. Its original architecture enables its use as a formal framework for the description of morphological analyses and as a repository for existing lexicons. It is fed with a variety of resources, which all are already validated. The harmonization of their content into a unified format provides them a second li...

This research is aimed at developing a hierarchical alternation-based lexical architecture for machine translation. The proposed architecture makes extensive use of information sharing in describing valency frames through derivational links from base frames, rather than as independent entities. This has advantages in descriptive efficiency, robustness and maintainability. The lexicon being deve...
