Stative, Causative and Resultative Predicates in Discourse. Semantics of Evaluative Adjectives and Psychological Verbs (Les prédicats statifs, causatifs, et résultatifs en discours. Sémantique des adjectifs évaluatifs et des verbes psychologiques)Martin, Fabienne 19 September 2006 (has links)
<p align="justify">Cette thèse analyse les propriétés sémantiques et discursives des prédicats d'état (<i>laid, généreux</i>) ainsi que des prédicats causatifs et résultatifs, et plus particulièrement des verbes psychologiques à Expérienceur objet (<i>stimuler, encourager</i>). Le cadre adopté est celui de la sémantique néo-davidsonienne (Parsons, 1990) et de la sémantique du discours (Kamp & Reyle 1993, Asher 1993). La première partie (chap 1-7) est consacrée aux prédicats d'état, et la seconde aux prédicats causatifs et résultatifs (chap. 8-9). </p>
<p align="justify">Dans le chapitre 1, on expose les arguments en faveur de l'idée que les verbes d'état ont un argument implicite davidsonien comme les verbes d'action. Abordant ensuite les constructions en <i>by/in</i> (<i>by/in smoking, he broke his promise</i>), l'auteur propose de considérer, avec Goldman et contre Davidson, que celles-ci décrivent deux événements distincts, liés par une relation de génération. L'analyse goldmanienne de ces constructions est ensuite étendue aux prédicats d'état (<i>in doing this, he was clever</i>), ce qui permet de distinguer les prédicats qui dénotent un état dépendant d'une action, comme <i>clever</i> en usage occurrentiel, des prédicats qui dénotent un état indépendant d'une action, comme <i>beautiful</i> (cf. ??<i>in doing this, he was beautiful</i>). </p>
<p align="justify">Le chapitre 2 fait le point sur les spécificités des prédicats d'état par rapport aux prédicats d'activité. Y est notamment montré que certains prédicats d'état acceptent le "progressif interprétatif" (<i>tu es en train de croire au Père Noël!</i>). Ce type de progressif est distingué du progressif standard et du progressif actif anglais (<i>he was being clever</i>); sont définis également les "prédicats interprétatifs" qui n'acceptent que ce progressif.</p>
<p align="justify">Le chapitre 3 élabore une typologie aspectuelle des prédicats d'état. Sont d'abord distingués quatre types d'états en fonction de l'intervalle pendant lequel l'état en cause est vérifié. On montre que cette quadri-partition rend mieux compte des données linguistiques que la dichotomie classique en <i>stage level predicates et individual level predicates</i>. Ensuite sont définis les "prédicats d'état pur" comme <i>beau</i>, qui dénotent un état indépendant de toute action, et les "prédicats d'état endo-actionnel" comme <i>généreux/bruyant</i> en usage occurrentiel, qui dénote un état généré par une action. On présente des arguments contre l'assimilation de ces derniers prédicats à des prédicats d'action. Est alors analysée l'ambiguïté des prédicats comme "généreux" dans l'emploi occurrentiel: <i>Pierre m'a donné des bonbons. Il a été généreux</i> peut vouloir dire soit que Pierre a été généreux de (décider de) me donner des bonbons (lecture-d), soit qu'il a été généreux dans la manière de me les donner (lecture-m). Dans la foulée, on examine la relation temporelle qui prend place entre un état <i>s</i> et l'action <i>e</i> dont il dépend. Enfin, on montre que l'analyse proposée peut rendre compte de la concurrence entre passé composé et imparfait dans les phrases dénotant un état occurrentiel.</p>
<p align="justify">A partir de la typologie aspectuelle élaborée au chapitre 3, le chapitre 4 revisite le problème que soulèvent certains prédicats d'état dans les constructions à prédicat second descriptif (<i>Pierre a donné des bonbons saoul/??généreux</i>) et propose une nouvelle solution. On montre ensuite que cette solution peut être adaptée pour résoudre un problème moins étudié, à savoir celui que posent certains prédicats d'état dans les subordonnées temporelles en <i>quand</i> (cf. <i>Il était généreux, quand il a distribué les bonbons versus ??Il a distribué des bonbons quand il était généreux</i>). Enfin, on fait le point sur la difficulté qu'éprouvent les prédicats évaluatifs à entrer dans les constructions présuppositionnelles, parmi lesquelles les subordonnées temporelles, mais les GN définis (<i>La femme rousse/??généreuse commanda une bière</i>).</p>
<p align="justify">Le chapitre 5 est consacré aux relations rhétoriques qui s'établissent entre la description d'un état et la description d'un événement, aux combinaisons possibles entre ces relations rhétoriques, et à la manière dont tel ou tel prédicat d'état, vu ses propriétés sémantiques, contribue à établir telle ou telle relation rhétorique avec la description d'événement. </p>
<p align="justify">Le chapitre 6 revient sur le problème que soulève l'indéfini des en lecture non générique avec certains prédicats d'état, notamment les prédicats évaluatifs (<i>Des livres étaient sales versus ??Des livres étaient merveilleux</i>). En se fondant sur les outils de la <i>Decision Theoretic Semantics</i> (Merin 1999), l'auteur fait l'hypothèse qu'un prédicat <i>P</i> n'accepte <i>des</i> que si la quantité des éléments satisfaisant <i>P</i> dans le contexte est non pertinente pour les fins du discours, et s'il est clair, par ailleurs, que les <i>qualités</i> implicites que peuvent instancier les dits éléments ne contribuent en aucune façon à expliquer qu'ils satisfont <i>P</i>. On montre que ces deux conditions sont respectées (resp. violées) avec les prédicats d'état compatibles (resp. incompatibles) avec <i>des</i> dans sa lecture non générique.</p>
<p align="justify">Le chapitre 7 est consacré à la sémantique qu'il faut assigner aux prédicats d'état <i>évaluatifs</i>. On expose tout d'abord les arguments en faveur d'une sémantique "réaliste", qui analyse les prédicats évaluatifs comme des prédicats unaires dénotant de vraies propriétés. On distingue ensuite, dans le contenu informationnel des énoncés évaluatifs, un composant assertif et deux implicatures associées. On termine par l'analyse des prédicats évaluatifs superlatifs (<i>merveilleux</i>); est argumentée l'idée que ces prédicats ont un composant expressif, en ce sens que le locuteur, en les utilisant, implicite qu'une entité satisfaisant le prédicat a déclenché en lui une émotion, vécue ou rejouée lors de l'énonciation. On montre en quoi ce composant expressif contribue à expliquer pourquoi de tels prédicats sont difficilement utilisables à l'impératif ou dans certains types de questions.</p>
<p align="justify">Le chapitre 8 répertorie trois classes parmi les verbes, dits "résultatifs", qui présupposent l'occurrence d'un événement <i>e</i> causant ou générant l'événement asserté <i>e'</i>. On présente d'abord le problème que pose la définition de cette présupposition, puis une nouvelle solution est exposée. On montre alors que la présupposition des verbes résultatifs -- achèvements droits et accomplissements strictement forts --- est de nature scalaire et peut s'expliquer par la Loi d'exhaustivité de Ducrot.</p>
<p align="justify">Le chapitre 9 est consacré aux verbes psychologiques à Expérienceur objet (VPEO). Après avoir classé ces verbes en fonction de leur structure événementielle, on fait le point sur les différentes lectures qu'ils peuvent accepter. On montre ensuite qu'à la différence des VPEO acceptables dans les constructions agentives, les VPEO qui y sont peu acceptables exhibent deux propriétés cruciales. D'abord, ils présupposent toujours, à l'instar des verbes étudiés dans le chapitre 8, l'occurrence de l'événement impliquant le sujet; ensuite, certains d'entre eux sont "interprétatifs", en ce sens que l'assertion du changement d'état psychologique ne s'avère pertinente pour les fins du discours que si l'interprétant connaît, par ailleurs, l'événement qui cause ce changement. Cela permet d'expliquer pourquoi les verbes en question ne peuvent faire avancer la narration comme le ferait un prédicat d'action normal, et pourquoi ils sont peu compatibles avec les adverbes de manière orientés sur l'agent, les pseudo-clivées ou les compléments de lieu.</p>
<p align="justify">On termine par l'analyse aspectuelle de la classe des VPEO, en montrant qu'on y trouve des membres des cinq classes aspectuelles distinguées dans le chapitre précédent.</p>

Analysis, synthesis and application of automaton-based constraint descriptionsFrancisco Rodríguez, María Andreína January 2017 (has links)
Constraint programming (CP) is a technology in which a combinatorial problem is modelled as a conjunction of constraints on variables ranging over given initial domains, and optionally an objective function on the variables. Such a model is given to a general-purpose solver performing systematic search to find constraint-satisfying domain values for the variables, giving an optimal value to the objective function. A constraint predicate (also known as a global constraint) does two things: from the modelling perspective, it allows a modeller to express a commonly occurring combinatorial substructure, for example that a set of variables must take distinct values; from the solving perspective, it comes with a propagation algorithm, called a propagator, which removes some but not necessarily all impossible values from the current domains of its variables when invoked during search. Although modern CP solvers have many constraint predicates, often a predicate one would like to use is not available. In the past, the choices were either to reformulate the model or to write one's own propagator. In this dissertation, we contribute to the automatic design of propagators for new predicates. Integer time series are often subject to constraints on the aggregation of the features of all maximal occurrences of some pattern. For example, the minimum width of the peaks may be constrained. Automata allow many constraint predicates for variable sequences, and in particular many time-series predicates, to be described in a high-level way. Our first contribution is an algorithm for generating an automaton-based predicate description from a pattern, a feature, and an aggregator. It has previously been shown how to decompose an automaton-described constraint on a variable sequence into a conjunction of constraints whose predicates have existing propagators. This conjunction provides the propagation, but it is unknown how to propagate it efficiently. Our second contribution is a tool for deriving, in an off-line process, implied constraints for automaton-induced constraint decompositions to improve propagation. Further, when a constraint predicate functionally determines a result variable that is unchanged under reversal of a variable sequence, we provide as our third contribution an algorithm for deriving an implied constraint between the result variables for a variable sequence, a prefix thereof, and the corresponding suffix.

A Syntactic Analysis of Motion Predicates in Southern Tati (Takestani Dialect)Neda Taherkhani (7041479) 16 August 2019 (has links)
This dissertation provides a syntactic representation of Motion Predicates (MPs) expressed by series of verbs known as Serial Verb Constructions (SVCs) in Southern Tati –an Indo-European language spoken mainly in the Northwestern parts of Iran. This study addresses the sub-eventive decomposition of MPs by following the theoretical framework established by generative-constructivists like Borer (2005) and Ramchand (2008), as implemented for MPs in Benedicto and Salomon (2014).This dissertation also contributes to the documentation of Southern Tati, which iscategorized by UNESCO as ‘definitely’endangered.<br>

Processing Compound Verbs in PersianShabani-Jadidi, Pouneh 17 April 2012 (has links)
This study investigates how Persian compound verbs are processed in the mental lexicon, through which we can infer how they are stored, organized, and accessed. The study focuses on investigating Persian compound verbs in light of psycholinguistic theories on polymorphemic word processing as well as linguistic theories of complex predicates.
The psycholinguistic section details three experiments addressing the following three research questions: (1) whether compound verb constituents show significant priming in the masked-priming paradigm; (2) whether priming effects are constrained by semantic transparency; and (3) whether priming effects are due to morphological relatedness.
This study revealed several findings: (1) compound verbs in Persian are decomposed into their constituents at early stages of processing, (2) at early stages of processing, decomposition is based on purely orthographic similarity, (3) although both transparent and opaque compound constituents were facilitated while processing, transparency had an impact on processing in the early stages of processing.
Finally, the findings seem to support a parallel input effect or competing alternative effect for the verbal constituent of the transparent compound verb, as reflected in the slower facilitation for the verbal constituent compared to the nominal constituent.
In theoretical studies on Persian complex predicates, the compound verb formation can be either lexical or syntactic. The overall evidence reflected in the linguistic data for Persian complex predicates presented in this dissertation as well as the results of the experimental studies carried out in this research seem to point towards lexical compounding in Persian compound verb formation. The evidence comes from (1) the nominalization of the compound, i.e. the possibility of using the compound verb as a noun; (2) the atelicity feature, i.e. the possibility of using the compound verb after the progressive expression dar haale ‘in the process of’, which indicates an incomplete action; and (3) the nonreferentiality of the nominal constituent in the compound verb, i.e. the nominal constituent cannot be followed by a pronoun that refers to it.
On the other hand, the results of the experimental studies reported in this dissertation seem to support a lexical approach to compound verbs in Persian. The technique used in these experimental studies was masked priming paradigm, which investigates the prelexical and lexical processing. The results reveal constituent priming effects under masked priming technique. This indicates that Persian compound verb constituents are accessed at the prelexical stage of processing. Syntactic calculations are said to be done at later stages of processing. Therefore, the early processing of compound verb constituents leads us to the argument for the lexicality of Persian compound verbs.

The Sense of Self: Topics in the Semantics of De Se ExpressionsPearson, Hazel Anne January 2012 (has links)
This work investigates a series of phenomena that shed light on the analysis of attitudes de se. We adopt Lewis’ (1979) proposal that attitudes de se involve self-ascription of a property, and investigate how this view of mental content is reflected in natural language. The implementation favored is a strong version of Lewis’ position: root and embedded clauses are uniformly treated as being of property type. Our approach elaborates Chierchia’s (1990) view that de se construals arise via binding by an abstraction operator in the clausal left periphery. Part I develops an argument that such operators occur in root as well as embedded clauses. This is contrasted with the view that the evaluation index incorporates an individual parameter, a prominent version of which treats the behavior of predicates of taste such as tasty as evidence that truth is relativized to individuals (Lasersohn, 2005; Stephenson, 2007a, 2007b). Chapter 2 argues against this view, defending a semantics for taste predicates that requires no appeal to an individual parameter. Chapter 3 employs an argument from Moore’s Paradox to motivate the proposal that root clauses bear individual abstractors in their left periphery, while Chapter 4 identifies phenomena that the system accounts for. Part II concerns two elements whose distribution is confined to embedded clauses: controlled PRO and the logophoric pronoun in the Niger-Congo language Ewe. Chapters 5 and 6 investigate the semantics of partial control, a variety of control where the controller denotes a proper subset of the understood subject. The view that control complements express properties lends itself to a principled account of which predicates license partial control. Chapter 7 presents novel data regarding the logophoric pronoun in Ewe. We show that, contrary to what had been assumed in the absence of the necessary fieldwork, Ewe logopohors are not obligatorily de se. We propose an account of this finding that is compatible with the implementation of the property view that we favor. Chapter 8 closes the dissertation by considering why it should be that certain expressions, such as PRO, are obligatorily de se while others, like the Ewe logophor, can be de re. / Linguistics

[en] EXPERIMENTAL STUDY OF CONJUNCTIVE QUERIES OPTIMIZATION WITH EXPENSIVE PREDICATES / [pt] ESTUDO EXPERIMENTAL DE ALGORITMOS PARA OTIMIZAÇÃO DE CONSULTAS CONJUNTIVAS COM PREDICADOS CAROSRODRIGO SILVA GUARINO 12 July 2004 (has links)
[pt] As técnicas tradicionais de otimização de consultas em
banco de dados possuem como heurística fundamental a
organização dos predicados de uma consulta em dois tipos
principais: predicados simples e predicados
envolvendo junção(join) de tabelas. Como príncipio geral
considera-se a priori os predicados envolvendo junção bem
mais caros do que os predicados simples, e também que não
existam diferenças significativas entre os tempos de
processamento dos predicados simples, o que leva o
otimizador a executar primeiro os predicados simples(em
uma
ordem qualquer), a fim de se diminuir a quantidade de
tuplas que seriam necessárias à execução da junção. Essa
consideração que se aplica bem à maioria das aplicações
convencionais de banco de dados, passou a não se aplicar
mais à novas aplicações que envolviam o preprocessamento
de
dados e/ou funções complexas nos predicados que não
envolviam junções. Dessa forma esses novos predicados
simples passaram a ter um tempo de processamento não mais
desprezível em relação aos predicados que envolviam
junções
e também em relação a outros predicados simples. Dessa
forma a heurística principal de otimização não se
aplicava
mais e tornou-se necessário o desenvolvimento de novas
técnicas para resolver consultas que envolvessem esse
novo
tipo de predicado, que passou a ser chamado de predicado
caro. O presente trabalho tem dois objetivos principais:
apresentar um framework que possibilite o
desenvolvimento,
teste e análise integrada de algoritmos para o
processamento de predicados caros, e analisar o
desempenho
de quatro implementações de algoritmos baseados na
abordagem Cherry Picking, cujo o objetivo é explorar a
dependência entre os dados que compõem as consultas. Os
experimentos são conduzidos em consultas envolvendo
predicados conjuntivos (AND) e a idéia geral é tentar
avaliar os atributos em uma ordem que minimize o custo de
avaliação geral das tuplas. / [en] Traditional database query optimization technique have as
its
main heuristic the organization of predicates in two main
types: selection
predicates and join predicates. Join predicates are
considered much more
expensive than selection predicates. In additional, it's
also considered that there's no big difference among the
costs of different selection predicates,
what makes the optimizer executes them first in any order,
reducing the number of tuples necessary to execute join
predicates.This assumption, that is well applied in
traditional database applications, becomes invalid
in respect of recent database applications, that executes
complex functions over complex data in selection
predicates. In this cases, selection predicates
are considered more expensive than join predicates and
their costs cannot be considered equivalent anymore. This
makes the main heuristic of push down selections invalid
for these kind of new selection predicates which calls for
new optimization techniques. These type of cue named
expensive predicates. This work has two main objectives:
Present a software that makes possible the development,
test and integrat analisys of different algorithms for
evaluating expensive predicates and analyse the performance
of four algorithm's implementations that are based on
Cherry Picking strategy, which aims at exploring the data
dependency between input values to expensive predicates.
The experiments considered conjunctive(AND) queries, and
the general idea is to try evaluate the attributes in a
order that minimizes the general cost of the tuples.

Resolvendo a anafora conceitual = um olhar para alem da relação antecedente/anaforico / Conceptual anaphora resolution : a view beyond the antecedent-anaphor relationGodoy, Mahayana Cristina, 1985- 15 August 2018 (has links)

Previous issue date: 2010 / Resumo: A resolução da anáfora conceitual traz questões interessantes para a pesquisa psicolingüística, pois abre a possibilidade de investigar como um pronome plural pode ser resolvido a partir de uma expressão antecedente singular, como em "O batalhão foi vacinado. Eles foram para a África". De acordo com Landman (1989), grupos como "batalhão" podem ter uma denotação plural quando recebem uma predicação distributiva (e.g., foi vacinado), mas também podem ter uma denotação singular quando são predicados coletivamente (e.g., foi reorganizado). Em outras palavras, enquanto o predicado seleciona a pluralidade de membros que compõem o batalhão no primeiro caso, no segundo, o mesmo batalhão é predicado como instituição, i.e., como uma entidade singular. Com base nessas considerações, é razoável assumir que a leitura coletiva ou distributiva determinada pelo predicado pode influenciar a resolução pronominal, desde que se considere a saturação anafórica como produto de expectativas geradas pelos leitores acerca de quais referentes têm chances de serem mencionados em partes subseqüentes do texto (Kehler et al., 2007). Para testar esta hipótese, elaboramos dois experimentos. No primeiro deles, investigamos se as leituras coletiva ou distributiva de expressões como "pelotão" poderiam criar expectativas sobre como os sujeitos dariam continuações para sentenças na voz passiva. Os participantes deveriam completar sentenças como "Para viajar ao exterior, o batalhão foi vacinado" apontando seu agente. Os resultados indicam que a continuação para predicados coletivos era preferencialmente um agente singular, enquanto para os distributivos o agente dado tendia a ser plural. Em um segundo experimento, os sujeitos liam sentenças com anáforas conceituais cujo antecedente era predicado coletiva ou distributivamente. O tempo de leitura do pronome nessas duas situações foi comparado, apontando para um tempo significativamente maior quando o pronome seguia uma predicação coletiva. Ambos os resultados, portanto, confirmam nossas hipóteses, indicando que os predicados de termos de grupo podem gerar expectativas que influenciam a resolução da anáfora conceitual / Abstract: Conceptual anaphora resolution brings interesting questions to research in psycholinguistics, for it provides the possibility of investigating how a plural pronoun can be solved from a singular antecedent, as one can see in "The army division was vaccinated. They went to Africa". According to Landman (1989), groups such as "the army division" can have a plural denotation when it receives a distributive predicate (e.g., was vaccinated), but it can also have a singular denotation when its predicate is a collective one (e.g., was reorganized). In other words, while the predicate selects the plurality of members that compose the army division in the first case, in the second one the same army division is predicated as an institution, i.e., as a singular entity. From these considerations, it is reasonable to assume that collective or distributive readings determined by the predicate can influence pronoun resolution, if one consider anaphora resolution as a product of the expectations generated by the readers about which referents are more likely to be mentioned in subsequent text (Kehler et al., 2007). In order to test this hypothesis, we ran two experiments. In the first one, we investigated whether collective or distributive readings of expressions similar to "the army division" would create expectations on how subjects provide continuations for passive sentences. The participants should complete sentences such as "In order to go abroad, the army division was vaccinated" with their agents. The result indicates that the continuation given to collective predicates was preferably a singular agent, while the continuations provided to distributive predicates tended to be plural agents. In a second experiment, subjects read sentences with conceptual anaphoras whose antecedent was predicated in a collective or distributive way. The pronoun reading time in these two situations was compared, showing a significant longer time when the pronoun followed collective predication. Therefore, both results corroborate our hypothesis, indicating that the way groups are predicated can generate expectations that influence conceptual anaphora resolution / Mestrado / Linguistica / Mestre em Linguística

Statistical Debugging of Programs written in Dynamic Programming Language : RUBY / Statistisk Debugging av program skrivna i dynamiskt programmeringsspråk : RUBYAkhter, Adeel, Azhar, Hassan January 2010 (has links)
Debugging is an important and critical phase during the software development process. Software debugging is serious and tough practice involved in functional base test driven development. Software vendors encourages their programmers to practice test driven development during the initial development phases to capture the bug traces and the associated code coverage infected from diagnosed bugs. Application’s source code with fewer threats of bug existence or faulty executions is assumed as highly efficient and stable especially when real time software products are in consideration. Due to the fact that process of development of software projects relies on great number of users and testers which required having an effective fault localization technique. This specific fault localization technique can highlight the most critical areas of software system at code as well as modular level so that debugging algorithm can be used to debug the application source code. Nowadays many complex or simple software systems are in corporation with open bug repositories to localize the bugs. Any inconsistency or imperfection in early development phase of software product results in low efficient system and less reliability. Statistical debugging of program source code for visualization of fault is an important and efficient way to select and rank the suspicious lines of code. This research provides guidelines for practicing statistical debugging technique for programs coded in Ruby programming language. This thesis presents statistical debugging techniques available for dynamic programming languages. Firstly, the statistical debugging techniques were thoroughly observed with different predicate base approaches followed in previous work done in the subject area. Secondly, the new process of statistical debugging for programs coded in Ruby programming language is introduced by generating dynamic predicates. Results were analyzed by implementing multiple programs written in Ruby programming language with different complexity level. The analysis of experimentation performed on candidate programs depict that SOBER is more efficient and accurate in bug identification than Cause Isolation Scheme. It is concluded that despite of extensive research in the field of statistical debugging and fault localization it is not possible to identify majority of the bugs. Moreover SOBER and Cause Isolation Scheme algorithms are found to be two most mature and effective statistical debugging algorithms for bug identification with in software source code. / Address: School of Computing Blekinge Institute of Technology SE-371 79 Karlskrona, Sweden Phone: +46-(0)455-385804 Fax: +46-(0)455-385057
