Multicomponent Tree Adjoining Grammars (MCTAG) is a formalism that has been shown to be useful for many natural language applications. The definition of MCTAG however is problematic since it refers to the process of the derivation itself: a simultaneity constraint must be respected concerning the way the members of the elementary tree sets are added. Looking only at the result of a derivation (i.e., the derived tree and the derivation tree), this simultaneity is no longer visible and therefore cannot be checked. I.e., this way of characterizing MCTAG does not allow to abstract away from the concrete order of derivation. Therefore, in this paper, we propose an alternative definition of MCTAG that characterizes the trees in the tree language of an MCTAG via the properties of the derivation trees the MCTAG licences.
We present a broad coverage Japanese grammar written in the HPSG formalism with MRS semantics. The grammar is created for use in real world applications, such that robustness and performance issues play an important role. It is connected to a POS tagging and word segmentation tool. This grammar is being developed in a multilingual context, requiring MRS structures that are easily comparable across languages.
This paper is concerned with developing Joan Bybee's proposals regarding the nature of grammatical meaning and synthesizing them with Paul Hopper's concept of grammar as emergent. The basic question is this: How much of grammar may be modeled in terms of grammaticalization? In contradistinction to Heine, Claudi & Hünnemeyer (1991), who propose a fairly broad and unconstrained framework for grammaticalization, we try to present a fairly specific and constrained theory of grammaticalization in order to get a more precise idea of the potential and the problems of this approach. Thus, while Heine et al. (1991:25) expand – without discussion – the traditional notion of grammaticalization to the clause level, and even include non-segmental structure (such as word order), we will here adhere to a strictly 'element-bound' view of grammaticalization: where no grammaticalized element exists, there is no grammaticalization. Despite this fairly restricted concept of grammaticalization, we will attempt to corroborate the claim that essential aspects of grammar may be understood and modeled in terms of grammaticalization. The approach is essentially theoretical (practical applications will, hopefully, follow soon) and many issues are just mentioned and not discussed in detail. The paper presupposes a familiarity with the basic facts of grammaticalization and it does not present any new facts.
Mwani : grammatical sketch
(2010)
Kimwani, the language of the Wamwani or Mwani people, is spoken by about 80,000 people in the Cabo Delgado province of Mozambique. The language is related to Swahili, but the two are not mutually intelligible.
The prestige dialect of Kimwani is KiWibu, spoken on Ibo Island and surroundings, as well as by the majority of Mwani in the provincial capital, Pemba. KiWibu forms have consistently been followed in this write-up, unless otherwise indicated. For differences with other dialects, see Appendix E "Dialectical variations and their characteristics".
Based on a detailed case study of parallel grammar development distributed across two sites, we review some of the requirements for regression testing in grammar engineering, summarize our approach to systematic competence and performance profiling, and discuss our experience with grammar development for a commercial application. If possible, the workshop presentation will be organized around a software demonstration.
In this paper we present a parsing architecture that allows processing of different mildly context-sensitive formalisms, in particular Tree-Adjoining Grammar (TAG), Multi-Component Tree-Adjoining Grammar with Tree Tuples (TT-MCTAG) and simple Range Concatenation Grammar (RCG). Furthermore, for tree-based grammars, the parser computes not only syntactic analyses but also the corresponding semantic representations.
It is the aim of this paper to present and elaborate a new solution to the old syntactic problems connected with the Latin gerundive and gerund, two verbal categories which have been interpreted variously either as adjective (or participle) or noun (or infinitive). These questions have been much discussed for quite a number of years […] but for the most part from a philological or purely diachronic point of view. All these linguists try to explain the peculiarities of these categories and their syntax by showing that the gerund is historically prior to the gerundive. [...] It is our thesis […] that in order to arrive at a unified account of gerundive and gerund we do not have to go back to prehistoric times. Even for the classical language gerund and gerundive represent the same category, in the sense that the gerund can be shown to be a special case of the gerundive. Additional evidence from a parallel construction in Hindi is adduced to make the Latin facts more plausible. It is only in the post-classical language that certain tendencies which had shown up already in Old Latin poetry become stronger and finally lead to a reanalysis of the gerundive and a split into two distinct syntactic constructions. The propositional meaning of the gerundive in its attributive use is explained with reference to a conflict between syntactic and cognitive principles. Special constructions which are the effects of such conflicts can be found in other parts of grammar. Languages differ with respect to the degree of syntacticization (or conventionalization) of these special constructions.
