Comparative correlative (CC) constructions have received much attention in recent years. Major issues have been whether they involve special constructions and whether they have symmetric or asymmetric structures. Evidence from Romance suggests that they require special constructions and that they may be either symmetric or asymmetric. French has a single construction which is asymmetric for some speakers and symmetric for others. Spanish has two distinct constructions, one asymmetric and the other symmetric with quite different properties. The facts can be accommodated in a straightforward way within construction-based HPSG.
Abstract: A functional typology of copular be in Russian allows us to systematically relate variants of predication with and without copula. The analysis sketched in this article does not need empty categories; neither does it have to stipulate categories, category changes or constituents that are not morphologically signalled. With regard to HPSG formalization, the presented approach independently motivates the use of features and mechanisms that are already available in this framework.
Conventional wisdom holds that productive morphology is regular morphology. Drawing evidence from French, we argue that the description of many lexeme formation processes is simplified if we hold that a productive rule may give rise to inflectionally irregular lexemes. We argue that the notion of a stem space allows for a straightforward description of this phenomenon: each lexeme comes equipped with a vector of possibly distinct stems, which serve as bases for inflectional form construction. The stem space is structured by default relations which encode the regular pattern of inflection; (partial) irregularities occur when a lexeme specifies a stem space violating the default relations. Derived irregularity is then the effect of a productive lexeme formation rule which specifies an irregular stem space for its output.
Metrical phonology in HPSG
(2006)
This paper proposes a new approach to the prosody-syntax interface in HPSG. Previous approaches to prosody in HPSG (Klein, 2000; Haji-Abdolhosseini, 2003) represent prosodic information by constructing metrical constituent structure in the tradition of (Selkirk, 1980; Liberman and Prince, 1977). One drawback of this approach is that it does not allow for a direct representation of purely metrical constraints, which are relegated to an unformalized performance component. By contrast, so called 'grid only' approaches (Prince, 1983; Selkirk, 1984; Delais-Roussarie, 2000) use a single data structure, a metrical grid, to encode prosodic constraints resulting from syntax and constraints of a rhythmic nature.
We first review relevant data from French showing that prosodic constituency is much less constrained by syntactic structure than is predicted by existing approaches. In all but very short utterances, many different prosodic groupings are possible for a given sentence with a determinate information structure, and rhythmic factors determine a preference ordering on the possible groupings. We then present an HPSG implementation of the metrical grid, and propose minimal syntactic constraints on relative prominence, leaving room for noncategorical rythmic constraints to choose between alternatives. We finish by discussing the interaction of the metrical grid with the rest of the prosodic grammar.
Languages often require negation to be realized in a prominent position. A well known example is Italian, which seems to require a pre-verbal realization of negation. Some other languages require negation to be in a prominent position but do not require it to be pre-verbal. An example is Swedish. Working within Lexical Functional Grammar (LFG), Sells (2000) proposes that Swedish requires a negative element which is not inside VP and that Italian has the same constraint. Similar facts are found in the VSO language Welsh. However, Sellss approach cannot be applied to Welsh. Borsley and Jones (2005) develop a selectional approach to Welsh, in which certain verbs require a negative complement. This works well for Welsh but cannot be applied to Swedish or Italian. A similar approach to all three languages is possible within the linearization-based version of Head-driven Phrase Structure Grammar (HPSG) developed by Kathol (2000). It seems, then, that a linear approach is preferable to both a structural and a selectional approach.
In this paper, we present an analysis of noun phrases with elided nouns that dispenses with the positing of empty categories and preserves the NP structure assumed for NPs with overt nouns, modulo the absence of the head noun. On a par with existing traceless analyses of long distance dependencies, this is proposed as a further step towards a more lean theory of grammar, without phonetically null items.
The "flexibility" of gender in Tigrinya is uncovered by (i) setting a value for gender for each noun at the lexical level (i.e. bare controllers) and (ii) analysing gender shifts as signals for evaluations (i.e. evaluated controllers). The analysis is formalized as lexical rules which change the value of gend and add an elementary predication in the rels list.
Temporal development of compensation strategies for perturbed palate shape in German /S/-production
(2006)
The palate shape of four speakers was changed by a prosthesis which either lowered the palate or retracted the alveoles. Subjects wore the prosthesis for two weeks and were recorded several times via EMA. Results of articulatory measurements show that speakers use different compensation methods at different stages of the adaptation. They lower the tongue immediately after the insertion of the prosthesis. Other compensation methods as for example lip protrusion are only acquired after longer practising periods. The results are interpreted as supporting the existence of different mappings between motor commands, vocal tract shape and auditory-acoustic target.
As has been noted previously, speakers with coronally low "flat" palates exhibit less articulatory variability than speakers with coronally high "domeshaped" palates. This phenomenon is investigated by means of a tongue model and an EPG experiment. The results show that acoustic variability depends on the shape of the vocal tract. The same articulatory variability leads to more acoustic variability if the palate is flat than if it is domeshaped. Furthermore, speakers with domeshaped palates show more articulatory variability than speakers with flat palates. The results are explained by different control strategies by the speakers. Speakers with flat palates reduce their articulatory variability in order to keep their acoustic variability low.
In this paper we describe SOBA, a sub-component of the SmartWeb multi-modal dialog system. SOBA is a component for ontologybased information extraction from soccer web pages for automatic population of a knowledge base that can be used for domainspecific question answering. SOBA realizes a tight connection between the ontology, knowledge base and the information extraction component. The originality of SOBA is in the fact that it extracts information from heterogeneous sources such as tabular structures, text and image captions in a semantically integrated way. In particular, it stores extracted information in a knowledge base, and in turn uses the knowledge base to interpret and link newly extracted information with respect to already existing entities.
