Object marking in the signed modality : Verbal and nominal strategies in Swedish Sign Language and other sign languages

Börstell, Carl January 2017 (has links)
In this dissertation, I investigate various aspects of object marking and how these manifest themselves in the signed modality. The main focus is on Swedish Sign Language (SSL), the national sign language of Sweden, which is the topic of investigation in all five studies. Two of the studies adopt a comparative perspective, including other sign languages as well. The studies comprise a range of data, including corpus data, elicited production, and acceptability judgments, and combine quantitative and qualitative methods in the analyses. The dissertation begins with an overview of the topics of valency, argument structure, and object marking, primarily from a spoken language perspective. Here, the interactions between semantics and morphosyntax are presented from a typological perspective, introducing differential object marking as a key concept. With regard to signed language, object marking is discussed in terms of both verbal and nominal strategies. Verbal strategies of object marking among sign languages include directional verbs, object handshape classifiers, and embodied perspective in signing. The first study investigates the use of directionality and object handshapes as object marking strategies in Al-Sayyid Bedouin Sign Language (ABSL), Israeli Sign Language (ISL), and SSL. It is shown that the strategies generally display different alignments in terms of the types of objects targeted, which is uniform across languages, but that directionality is much more marginal in ABSL than in the other two languages. Also, we see that there is a connection between object marking strategies and the animacy of the object, and that the strategies, object animacy, and word order preferences interact. In the second and third studies, SSL is investigated with regard to the transitive–reflexive distinction. Here, we see that there are interactional effects between object handshapes and the perspective taken by the signer. This points to intricate iconic motivations of combining and structuring complex verb sequences, such as giving preference to agent focusing structures (e.g., agent perspective and handling handshapes). Furthermore, the use of space is identified as a crucial strategy for reference tracking, especially when expressing semantically transitive events. Nominal strategies include object pronouns and derivations of the sign PERSON. The fourth study provides a detailed account of the object pronoun OBJPRO in SSL, which is the first in-depth description of this sign. It is found that the sign is in widespread use in SSL, often corresponds closely to object pronouns of spoken Swedish, and is argued to be grammaticalized from the lexical sign PERSON. In the final study, the possible existence of object pronouns in other sign languages is investigated by using a sample of 24 languages. This analysis reveals that the feature is found mostly in the Nordic countries, suggesting areal contact phenomena. However, the study also shows that there are a number of derivations of PERSON, such as reflexive pronouns, agreement auxiliaries, and case markers. The use of PERSON as a source of grammaticalization for these functions is attributed to both semantic and phonological properties of the sign. This dissertation is unique in that it is dedicated to the topic of object marking in the signed modality. It brings a variety of perspectives and methods together in order to investigate the domain of object marking, cross-linguistically and cross-modally.

Identification et modélisation lexicographique des dépendances syntaxiques régies du français: le cas des dépendances nominales

Arbour Barbaud, Évelyne 04 1900 (has links)
Cette recherche porte sur l’interface entre la sémantique lexicale et la syntaxe, et elle s’inscrit dans le cadre du projet de base lexicale DiCo (acronyme pour Dictionnaire de combinatoire) à l’Observatoire de Linguistique Sens-Texte [OLST] de l’Université de Montréal. Le projet découle d'une volonté d'inscrire de façon concise et complète, à même le dictionnaire, le comportement syntaxique typique à chaque unité lexicale. Dans cette optique, nous encodons la cooccurrence des lexies nominales du DiCo avec leurs actants à l'intérieur d'un tableau de régime lexical (aussi connu sous le nom de schéma valenciel, structure argumentale, cadre de sous-catégorisation, structure prédicats-arguments, etc.), en notant entre autres les dépendances syntaxiques de surface impliquées. Dans ce mémoire, nous présentons les propriétés syntaxiques d'une dépendance nominale du français, celle que nous avons nommée attributive adnominale, de façon à exposer une méthodologie d'identification et de caractérisation des dépendances syntaxiques de surface. Nous donnons également la liste des dépendances nominales régies identifiées au cours de ce travail. Par la suite, nous exposons la création d'une base de données de régimes généralisés du français nommée CARNAVAL. Finalement, nous discutons des applications possibles de notre travail, particulièrement en ce qui a trait à la création d'une typologie des régimes lexicaux du français. / This research focuses on the interface between lexical semantics and syntax, and is part of the lexical database project called DiCo (acronym for Dictionnaire de combinatoire) at the Observatoire de Linguistique Sens-Texte [OLST] at the University of Montreal. The project aims to register in a concise and complete way the typical syntactic behavior of each lexical unit directly in the dictionary. To this end, we encode the co-occurrence of the DiCo's nominal lexical units with their actants within a government pattern (also known as valency structure, subcategorization frame, predicate-argument structure, etc.), using, among other things, the surface syntactic dependencies involved. In this dissertation, we present the syntactic properties of a French nominal dependency, the one that we named attributive adnominale, so as to expose a methodology for the identification and the characterization of surface syntactic dependencies. We also give the list of valence-controlled nominal dependencies that were identified in our work. Subsequently, we describe the creation of a database of generalized French government patterns named CARNAVAL. Finally, we discuss possible applications of our work, particularly in regard to the creation of a typology of French government patterns.

Morphosyntaxe et sémantique grammaticale du salar et du tibétain de l'Amdo : analyse d'un contact de langues / Morphosyntax and grammatical semantics of the Salar and Amdo-Tibetan languages : analysis of a language contact

Simon, Camille 13 December 2016 (has links)
La présente étude s’inscrit dans le cadre plus vaste de la description des langues de l’aire linguistique Amdo. Cette région est caractérisée par la présence de langues sinitiques, mongoliques, tibétiques et turciques et, pour le salar et le tibétain, une situation de contact linguistique long d’environ sept siècles. Le salar est l’une des langues turciques les moins décrites et elle présente de nombreuses particularités dues à son isolement par rapport aux autres langues turciques. Il n’existe pas non plus de description des variétés de tibétain parlées dans la région salarophone, périphérique dans la tibétosphère. La perspective que nous adoptons ici est donc à la fois descriptive et comparative. Après un exposé des caractéristiques historiques et sociolinguistiques de cette situation de contact, nous analysons de façon détaillée des catégories grammaticales indexées dans le syntagme nominal et dans le prédicat. En particulier, nous proposons une nouvelle analyse des morphèmes de Temps-Aspect-Mode en salar et montrons que cette langue a copié en partie ses catégories évidentielles sur le modèle de celles du tibétain de l’Amdo. Nous nous intéressons ensuite aux problématiques liées à la valence verbale et aux effets du contact linguistique sur l’organisation accusative et ergative qui caractérisent respectivement le salar et le tibétain de l’Amdo. Nous analysons les marques casuelles à la fois comme relateurs, au sein du prédicat verbal, mais également comme converbe ou au sein des formes converbiales. Enfin, nous décrivons les catégories de voix grammaticalisées en salar et en tibétain, et montrons que celles-ci sont quasiment identiques dans les deux langues. / This study falls within the larger description of the languages of the Amdo linguistic area. This area is characterized by the coexistence of Sinitic, Mongolic, Tibetic and Turkic languages, and, regarding Salar and Tibetan, an approximately seven-century-long contact situation. Salar language remains one of the less described Turkic languages and, because of its isolation from the other Turkic languages, displays many specificities. There exists no description of the Amdo-Tibetan variety spoken in the Salar-speaking region either, this region being very peripheral in the Tibetosphere. The perspective taken in this study is thus both descriptive and comparative. After a depiction of the historical and sociolinguistic characteristics of this contact-situation, we analyse in detail the grammatical categories indexed in the nominal phrase and in the predicate. Notably, we suggest a new analysis of the Tense-Aspect-Mood morphemes in Salar and we show that the Amdo-Tibetan evidential categories have been partly copied in Salar. Then, the question of verb valency is addressed, and the effects of language contact on the Turkic accusative and on the Tibetic ergative organisation are explored. We analyze the case markers not only as markers of syntactic dependancy within the verb predicate, but also in their role as or in converbs. Finally, we describe the grammatical voices attested in Salar and in Amdo Tibetan, and show that the syntactic and semantic characteristics are almost identical in the two languages.

The Arabic verb : form and meaning in the vowel-lengthening patterns

Danks, Warwick January 2010 (has links)
The research presented in this dissertation adopts an empirical Saussurean structuralist approach to elucidating the true meaning of the verb patterns characterised formally by vowel lengthening in Modern Standard Arabic (MSA). The verbal system as a whole is examined in order to place the patterns of interest (III and VI) in context, the complexities of Arabic verbal morphology are explored and the challenges revealed by previous attempts to draw links between form and meaning are presented. An exhaustive dictionary survey is employed to provide quantifiable data to empirically test the largely accepted view that the vowel lengthening patterns have mutual/reciprocal meaning. Finding the traditional explanation inadequate and prone to too many exceptions, alternative commonalities of meaning are similarly investigated. Whilst confirming the detransitivising function of the ta- prefix which derives pattern VI from pattern III, analysis of valency data also precludes transitivity as a viable explanation for pattern III meaning compared with the base form. Examination of formally similar morphology in certain nouns leads to the intuitive possibility that vowel lengthening has aspectual meaning. A model of linguistic aspect is investigated for its applicability to MSA and used to isolate the aspectual feature common to the majority of pattern III and pattern VI verbs, which is determined to be atelicity. A set of verbs which appear to be exceptional in that they are not attributable to atelic aspectual categories is found to be characterised by inceptive meaning and a three-phase model of event time structure is developed to include an inceptive verbal category, demonstrating that these verbs too are atelic. Thus the form-meaning relationship which is discovered is that the vowel lengthening verbal patterns in Modern Standard Arabic have atelic aspectual meaning.

Towards deep content extraction from specialized discourse : the case of verbal relations in patent claims

Ferraro, Gabriela 20 July 2012 (has links)
This thesis addresses the problem of the development of Natural Language Processing techniques for the extraction and generalization of compositional and functional relations from specialized written texts and, in particular, from patent claims. One of the most demanding tasks tackled in the thesis is, according to the state of the art, the semantic generalization of linguistic denominations of relations between object components and processes described in the texts. These denominations are usually verbal expressions or nominalizations that are too concrete to be used as standard labels in knowledge representation forms -as, for example, “A leads to B”, and “C provokes D”, where “leads to” and “provokes” both express, in abstract terms, a cause, such that in both cases “A CAUSE B” and “C CAUSE D” would be more appropriate. A semantic generalization of the relations allows us to achieve a higher degree of abstraction of the relationships between objects and processes described in the claims and reduces their number to a limited set that is oriented towards relations as commonly used in the generic field of knowledge representation. / Esta tesis se centra en el del desarrollo de tecnologías del Procesamiento del Lenguage Natural para la extracción y generalización de relaciones encontradas en textos especializados; concretamente en las reivindicaciones de patentes. Una de las tareas más demandadas de nuestro trabajo, desde el punto vista del estado de la cuestión, es la generalización de las denominaciones lingüísticas de las relaciones. Estas denominaciones, usualmente verbos, son demasiado concretas para ser usadas como etiquetas de relaciones en el contexto de la representación del conocimiento; por ejemplo, “A lleva a B”, “B es el resultado de A” están mejor representadas por “A causa B”. La generalización de relaciones permite reducir el n\'umero de relaciones a un conjunto limitado, orientado al tipo de relaciones utilizadas en el campo de la representación del conocimiento.

Five English Verbs : A Comparison between Dictionary meanings and Meanings in Corpus collocations

Sörensen, Susanne January 2006 (has links)
In Norstedts Comprehensive English-Swedish Dictionary (2000) it is said that the numbered list of senses under each headword is frequency ordered. Thus, the aim of this study is to see whether this frequency order of senses agrees with the frequencies appearing in the British National Corpus (BNC). Five English, polysemous verbs were studied. For each verb, a simple search in the corpus was carried out, displaying 50 random occurrences. Each collocate was encoded with the most compatible sense from the numbered list of senses in the dictionary. The encoded tokens were compiled and listed in frequency order. This list was compared to the dictionary's list of senses. Only two of the verbs reached agreement between the highest ranked dictionary sense and the most frequent sense in the BNC simple search. None of the verbs' dictionary orders agreed completely with the emerged frequency order of the corpus occurrences, why complementary collocational learning is advocated.

Nitridonickelates: Preparation, Structure and Properties

Mehta, Akash 27 October 2005 (has links)
Low valent nickel (less than +1) complexes are rare in nature, however they are regularly encountered in nitridonickelate chemistry. Ternary alkaline earth nitridonickelates exhibit a variety of interesting crystal structures with respect to their covalently bonded nitridonickelate anionic framework. The coordination geometry of low valent nickel in these compounds presents a unique structural feature with nickel being in linear coordination by nitrogen atoms. The nitridonickelate frameworks of compounds investigated in this work are: Ba2[Ni3N2]: The first ternary alkaline earth nitridonickelates with 2D Ni-N anionic network. The formal oxidation state of Ni is +0.67. Ba2(Ba6N)[NiN]6: The structure is made of o1D helical Ni-N anionic chains. Also, the structural stability of this compound´s structure type was found to occur over a wide range of substitution of Ba by Ca and Sr; a max. of 70 percent Ba could be successfully replaced by Sr and Ca atoms retaining the same structure type. The formal oxidation state of Ni is +0.83. Ba[NiN] and the solid solution series Ba[CuxNi1-xN]: The structure is made of 1D zig-zag Ni-N chains. The solid-solution series is isostructural to Ba[NiN] at lower content of Cu while, at higher content it resembles Ba[CoN] structure type, however at very high Cu content it again transforms to Ba[NiN] structure type. The formal oxidation state of Ni is +1.0. Sr2[Ni(CN)N]: The structure consists of N-Ni-(CN) dumbbells. The compound is the first example of cyano-nitridonickelate. The formal oxidation state of Ni is 0. The handling of the ternary alkaline earth nitridonickelates in specific and also of the other nitridometalates in general suffers greatly due to their being air and moisture sensitive. This requires synthetic methods suitable for air and moisture sensitive samples and also the respective instrumental setup for the measurement of their physical properties under inert atmosphere. Up to now no comprehensive investigation of the physical properties of the ternary alkaline earth nitridonickelates has been made. In this work an emphasis was given to systematically investigate the physical properties of the ternary alkaline earth nitridonickelates and to understand their structure specific physical properties. The common features of the investigated ternary alkaline earth nitridonickelates are: 1. the low valency of nickel. 2. the linear coordination of Ni and octahedral coordination of N. During this investigation the low valent character of nickel was experimentally confirmed with the help of X-ray absorption spectroscopy and the interpretation of magnetic susceptibility data where the magnetic moments of the nickel atoms were always consistent with that of a low valent nickel species. The results obtained from the magnetic measurements and electrical conductivity shows that the alkaline earth nitridonickelates order antiferromagnetically at low temperatures and show temperature dependent metallic conductivity whereas the cyano-nitridonickelate Sr2[Ni(CN)N] does not order at low temperature, is paramagnetic, and exhibits semiconducting behaviour. This investigation has provided a better understanding of ternary alkaline earth nitridonickelates with respect to the different structure they exhibit and their associated physical properties. This work motivates to extend the investigations of the physical properties of other nitridometalates. These also exhibit different crystal structures with respect to their nitridometalate anionic framework and thus, structure specific physical properties are also to be expected.

Komplementace ditranzitivních sloves envy a forgive / Complementation of the ditransitive verbs envy and forgive

Hlaváčková, Veronika January 2021 (has links)
The subject of the present thesis is an analysis of the ditransitive verbs envy and forgive in the ditransitive/double-object constructions, i.e., either the S-V-Oi-Od or S-V-O-Oprep argument structure, in which both objects are explicitly expressed. Envy and forgive represents marginal ditransitive verbs, whose accounts in major grammars and various studies are far from uniform. Occasionally considered idiosyncratic, the ditransitive use (i.e., the indirect pattern) of the two verbs is expected to decrease in frequency. Thus, the research aims to investigate the postverbal complementation preference of envy and forgive, and the way the preference changes over time. However, it is not the relative frequency of the S-V-Oi-Od pattern with respect to all remaining constructions that is of interest here, but its ratio to the frequency of the other available double object construction, the prepositional S-V-O-Oprep pattern. Additionally, the thesis provides a systematic overview of syntactic and semantic differences between envy and forgive as well as an account of their shared features and aspects. Particular attention is paid to the Oi/O realisation (e.g., the substantival or pronominal realisation) and the Od/Oprep realisation (namely, the substantival realisation, the pronominal realisation, the...

Ukrajinsko-české interference (syntax) / Ukrainian-Czech Interferences (syntax)

Parashchak, Yuliia January 2021 (has links)
This thesis deals with Ukrainian-Czech interference at the syntactical level. The theoretical section deals with the terms we work with, defines both contrastive and error analyses, and focuses on syntactic differences between Ukrainian and Czech. The central part of this section focuses on different valencies for Czech and Ukrainian verbs. The practical section consist of an experiment in which we observe the error rate of Ukrainian students when using Czech verbs that have a different valency in Ukrainian. It also includes the differential valency dictionary of Czech and Ukrainian verbs, which is the result of this thesis. Key words: interference, positive transfer, negative transfer, contrastive analysis, error analysis, valency, verb pattern, syntax, Czech, Ukrainian, vocabulary
