Aspectual Properties of Spanish Absolute Small Clauses

The major aim of this paper consists in determining the aspectual constraints affecting absolute small clauses (ASCs) headed by a past participle. A detailed analysis of these constructions seems to indicate that there are enough arguments to postulate the existence of two types of ASCs: those having an NP direct internal argument (AASCs), and those in which this NP is phonetically unrealized (PASCs). The different temporal interpretation that these two types of ASCs can receive is one of the facts that most clearly support this distinction. From the analysis of the aspectual properties of ASCs, the following generalization arises: AASCs can only be formed from eventive predicates, whereas PASCs are not affected by these aspectual restrictions. Finally, an implementation in HPSG is proposed on the aspectual information necessary to capture our results.L'objectiu principal d'aquest article consisteix a intentar determinar les restriccions aspectuals que afecten les oraciones reduïdes absolutes (ORAs) el nucli de les quals és un participi. Una anàlisi detallada d'aquest tipus de construccions sembla indicar que hi ha arguments suficients per postular l'existència de dos tipus d'ORAs: aquelles que contenen un SN argument intern directe i aquelles en les quals aquest SN es troba elidit. La diferent interpretació temporal que poden rebre aquest dos tipus d'ORAs és un dels factors que més clarament incideixen en aquesta distinció. L'anàlisi de les propietats aspectuals de les ORAs també sembla incidir en la plausibilitat d'aquesta distinció. Així, les ORAs amb SN realitzat fonèticament només podran ésser constituïdes per predicats eventius, mentre que les ORAs amb SN elidit no es veuen afectades per aquestes restriccions aspectuals. Finalment, exposem una proposta d'implementació en el model HPSG de la informació aspectual necessària per copçar aquests fenòmens

Un análisis de parecido familiar de la construcción media: un enfoque funcional-cognitivo

This doctoral dissertation aims at delimiting the lexical-semantic and discourse-pragmatic features that regulate well-formedness in middle expressions and which could legitimate the adscription of a particular nominal, verb, or adjunct to the middle construction in English. The middle construction is here analysed in terms of its prototype effects (cf. Taylor, 1995; Langacker, 2008; Sakamoto, 2001; Goldberg, 1995; and Marín Arrese, 2001 and 2013), hence accommodating not only prototypical instances but also marginal structures largely ignored in the literature. This dissertation examines the prototype effects of the middle construction by exploring the Agent-like features of the Subject entity, the aspectuality of the verb, the role of the implicit Agent, and the nature of the middle adjunct. The structures analysed here conform a family of intransitive constructions that are understood as segments on the Unergative – Middle – Ergative continuum. The idea that the middle construction can actually be considered as a prototype category accommodating central and marginal structures contrasts with the postulates of the projectionist model (cf. Pinker, 1989; Ackema and Schoorlemmer, 1994; Hale and Keyser, 2002; and Fagan, 1992). The projectionist approach cannot account for the process of lexical-constructional interaction of the middle construction in an entirely satisfactory way. This is so because it does not attend to the prototype effects and discourse-pragmatic factors surrounding the middle construction, since it merely focuses on the structural information (cf. Hundt, 2007: 60; and Lemmens, 1998: 4). Therefore, it seems to be pertinent to apply the notions of ‘family-resemblance’ (cf. Wittgenstein, 1958) and ‘prototype effects’ (cf. Taylor, 1995) to the study of the middle construction, following cognitive-linguistic perspectives such as those of Lakoff (1987), Langacker (1987, 1991, 2008), Taylor (1995), and Goldberg (1995, 2006). The theory of prototypes allows for the application of the idea of a family-resemblance relation among different but related structures in order to justify the accommodation of non-prototypical cases into the prototype category. This doctoral dissertation applies a usage-based methodology to carry out a corpus study of contextualised examples. The compilation process has been conducted through the ‘Concordance’ within the Sketch Engine tool. The total sample retrieved and analysed here is 14099 instances, based on colloconstructional schemas which combine ±Animate subject entities with 254 different verbal predicates (cf. Levin, 1993), collocated with middable adjuncts (cf. Davidse and Heyvaert, 2007). The family-resemblance analysis challenges the traditionally accepted restricting features associated with the middle construction, thus demonstrating that both central and marginal structures can be accommodated within the middle prototype category. This is due to the fact that the segments of the continuum share certain commonalities with respect to their syntactic, semantic, pragmatic and cognitive underlying schemas, as well as a functional symmetry in the underlying structure of the subject and the verb (cf. Rijkhoff, 1991, 2002, 2008a and 2008b). In addition, the family-resemblance analysis of the middle prototype category is also based on the similarities and differences found across the family members examined in terms of their processes of Compositional Cospecification (cf. Yoshimura, 1998; Yoshimura and Taylor, 2004). Such process involves the specification of the semantics of the predicate in accordance with the meaning of the nominal and the semantic value of the adjunct in the middle construction. The family of constructions analysed includes: (i) prototypical action-oriented middles; (ii) prototypical ergative-like middles; (iii) the metonymically-motivated extensions of the action-oriented prototype (namely, Locative, Means, and Circumstanceof- Instrument middles); and (iv) metonymically-motivated extensions from the ergativelike prototype (namely, Agent-Instrument and Experiencer-Subject middles). Corpus data reveal that prototypical ergative-like middles are the most productive group (with 6801 instances, 68.24%), followed by prototypical action-oriented-middles (with 3633 examples, 25.77%). Among the metonymically-motivated extensions, the most productive structures are Experiencer-Subject middles (with 1789 instances, 12.69%), followed by Agent-Instrument middles (with 286 examples, 2.03%), whereas the least frequent types are Locative middles (with 48 instances, 0.34%), Means middles (with 60 examples, 0.43%), and Circumstance-of-Instrument middles (with 7 instances, 0.05%). The rest of corpus examples belong to the semantic types of Destiny- and Resultoriented middles (with 1475 instances, 10.46%).El propósito de esta tesis es delimitar las características léxico-semánticas y discursivo-pragmáticas que regulan la formación de expresiones medias y que podrían legitimar la adscripción de un determinado nominal, verbo o adjunto a la construcción media inglesa. La construcción media se analiza en términos de sus efectos prototípicos (cf. Taylor, 1995; Langacker, 2008; Sakamoto, 2001; Goldberg, 1995; y Marín Arrese, 2001 y 2013), acomodando no sólo ejemplos centrales sino también estructuras marginales generalmente ignoradas en la literatura. Esta tesis doctoral examina los efectos prototípicos de la construcción media mediante la exploración de las características pseudo-agentivas de la entidad sujeto, la aspectualidad del verbo, el rol del argumento agente implícito y la naturaleza del adjunto. Las estructuras analizadas forman una familia de construcciones intransitivas que se entienden como segmentos del continuo Inergativo – Medio – Ergativo. La idea de que la construcción media, de hecho, pueda considerarse como una categoría prototípica que acomoda estructuras centrales y periféricas contrasta con los postulados del modelo proyeccionista (cf. Pinker, 1989; Ackema y Schoorlemmer, 1994; Hale y Keyser, 2002; y Fagan, 1992). Dicho modelo no puede dar cuenta del proceso de interacción léxico-construccional de la construcción media de forma satisfactoria. Esto se debe a que el modelo proyeccionista no atiende a los efectos prototípicos y los factores discursivo-pragmáticos de la construcción media, ya que se centra únicamente en la información estructural (cf. Hundt, 2007: 60; y Lemmens, 1998: 4). Por ello, parece pertinente aplicar las nociones de ‘parecido familiar’ (cf. Wittgenstein, 1958) y ‘efectos prototípicos’ (cf. Taylor, 1995) al estudio de la construcción media, siguiendo perspectivas cognitivistas tales como las de Lakoff (1987), Langacker (1987, 1991, 2008), Taylor (1995) y Goldberg (1995, 2006). La teoría de los prototipos permite la aplicación de la idea de una relación de parecido familiar entre estructuras distintas pero relacionadas, justificando así la acomodación de casos marginales dentro de la categoría prototípica. Esta tesis doctoral aplica una metodología basada en el uso para llevar a cabo un estudio de corpus de ejemplos contextualizados. El proceso de compilación se ha llevado a cabo a través de la sección ‘Concordancia’ de la herramienta Sketch Engine. La muestra total analizada aquí es de 14099 ejemplos, basados en esquemas colo-construccionales en los que se combinan entidades de sujeto ±Animadas y 254 predicados verbales distintos (cf. Levin, 1993), colocados con adverbios compatibles con la construcción media (cf. Davidse y Heyvaert, 2007). El análisis de parecido familiar cuestiona las características restrictivas tradicionalmente asociadas con la construcción media, demostrando así que tanto las estructuras centrales como las marginales pueden acomodarse dentro de la categoría prototípica media. Esto se debe a que todos los segmentos del continuo comparten ciertas semejanzas con respecto a sus esquemas subyacentes de naturaleza sintáctica, semántica, pragmática y cognitiva, así como una simetría funcional en la estructura subyacente del sujeto y el predicado (cf. Rijkhoff, 1991, 2002, 2008a y 2008b). Además, el análisis de parecido familiar de la categoría prototípica media también se basa en las similitudes y diferencias encontradas entre los miembros de la familia de estructuras examinadas en función de sus procesos de Coespecificación Composicional (cf. Yoshimura, 1998; Yoshimura y Taylor, 2004). Dicho proceso se refiere a que la semántica del verbo se especifica de acuerdo con el significado del nominal y el valor semántico del adjunto en la construcción media. La familia de construcciones analizadas incluye: (i) medias prototípicas orientadas a la acción; (ii) medias prototípicas de naturaleza ergativa; (iii) extensiones metonímicamente motivadas de las medias prototípicas orientadas a la acción (concretamente, locativas, de medio e instrumentales de circunstancia); y (iv) extensiones metonímicamente motivadas de las medias prototípicas de naturaleza ergativa (concretamente, agentivo-instrumentales y de sujeto experimentador). Los datos del corpus examinado revelan que las medias prototípicas de naturaleza ergativa son las más productivas (con 6801 ejemplos, 68.24%), seguidas de las medias prototípicas orientadas a la acción (con 3633 ejemplos, 25.77%). Entre las extensiones motivadas metonímicamente, las estructuras más productivas son las medias de sujeto experimentador (con 1789 ejemplos 12.69%), seguidas de las medias agentivo-instrumentales (con 286 ejemplos, 2.03%), mientras que las menos frecuentes pertenecen a la clase de locativas (con 48 ejemplos, 0.34%), de medio (con 60 ejemplos, 0.43%), e instrumentales de circunstancia (con 7 ejemplos, 0.05%). El resto de ejemplos del corpus pertenecen a los tipos semánticos de medias orientadas al Destino y Resultado (con 1475 ejemplos, 10.46%)

Event phrase and the syntax of TMA verbs in Kuwaiti Arabic

PhD ThesisThis thesis investigates the syntax of various verbs in Kuwaiti Arabic which realise functional heads encoding Tense, Aspect and Modality, in addition to being used as lexical verbs. It investigates some fundamental issues such as the markedness of the perfective and imperfective verbal forms with respect to Tense and Aspect, and, the aspectual and temporal properties of the active participle form, which is generally considered a nominal category. This study incorporates the Event Phrase hypothesis building on Cowper (1999), Borer (2005), Ramchand (2008) and Travis (2010) and inspired from event-semantics (e.g. Davidson 1967, Higginbotham 1985 and Parsons 1990). EventP is a functional projection in the syntax of the clause that relates to the eventive argument (the Davidsonian argument). However, the details of how this phrase functions syntactically have not been precisely described, especially for Arabic. This research aims to clarify the functions of EventP based on data from KA. I argue that the EventP is a key ingredient in the syntactic representation of the clause structure. It relates to the distinction between eventive and non-eventive predicates, or the Individual-level and Stage-level predicates. Furthermore, I argue that analysing sentences in Arabic as eventive or non-eventive can account for a number of puzzling phenomena in the behaviour of verbal and non-verbal predicates. Some of these phenomena include: the null present tense copula; the mixed nominal and verbal behaviours of the active participle; the derivational gap with verbs such as yiʃbah ‘resemble’ and yigrab ‘relate to’; the varying temporal and aspectual readings of the imperfective depending on the verb class. An example of this is that the Achievement verbs resist the present tense and the progressive reading. I present an analysis of EventP that can account for these phenomena. Furthermore, I argue that analysing the predicates as eventive or non-eventive (following Adger and Ramchand 2003) allows for a more consistent generalisation of the functions of the TMA verbs discussed in this thesis, namely the auxiliary verb kaan ‘be.PAST’, the inceptive verb gaam ‘get up.INITIATE ’ and the durative verb gaʕad ‘sit.CONTINUE’. I show that it is possible to generalise over the functions of TMA verbs in relation to eventive sentences regardless of whether they have verbal or non-verbal predicates.Kuwait Universit

Processing temporal information in unstructured documents

Tese de doutoramento, Informática (Ciência da Computação), Universidade de Lisboa, Faculdade de Ciências, 2013Temporal information processing has received substantial attention in the last few years, due to the appearance of evaluation challenges focused on the extraction of temporal information from texts written in natural language. This research area belongs to the broader field of information extraction, which aims to automatically find specific pieces of information in texts, producing structured representations of that information, which can then be easily used by other computer applications. It has the potential to be useful in several applications that deal with natural language, given that many languages, among which we find Portuguese, extensively refer to time. Despite that, temporal processing is still incipient for many language, Portuguese being one of them. The present dissertation has various goals. On one hand, it addresses this current gap, by developing and making available resources that support the development of tools for this task, employing this language, and also by developing precisely this kind of tools. On the other hand, its purpose is also to report on important results of the research on this area of temporal processing. This work shows how temporal processing requires and benefits from modeling different kinds of knowledge: grammatical knowledge, logical knowledge, knowledge about the world, etc. Additionally, both machine learning methods and rule-based approaches are explored and used in the development of hybrid systems that are capable of taking advantage of the strengths of each of these two types of approach.O processamento de informação temporal tem recebido bastante atenção nos últimos anos, devido ao surgimento de desafios de avaliação focados na extração de informação temporal de textos escritos em linguagem natural. Esta área de investigação enquadra-se no campo mais lato da extração de informação, que visa encontrar automaticamente informação específica presente em textos, produzindo representações estruturadas da mesma, que podem depois ser facilmente utilizadas por outras aplicações computacionais. Tem o potencial de ser útil em diversas aplicações que lidam com linguagem natural, dado o caráter quase ubíquo da referência ao tempo cronólogico em muitas línguas, entre as quais o Português. Apesar de tudo, o processamento temporal encontra-se ainda incipiente para bastantes línguas, sendo o Português uma delas. A presente dissertação tem vários objetivos. Por um lado vem colmatar esta lacuna existente, desenvolvendo e disponibilizando recursos que suportam o desenvolvimento de ferramentas para esta tarefa, utilizando esta língua, e desenvolvendo também precisamente este tipo de ferramentas. Por outro serve também para relatar resultados importantes da pesquisa nesta área do processamento temporal. Neste trabalho, mostra- -se como o processamento temporal requer e beneficia da modelação de conhecimento de diversos níveis: gramatical, lógico, acerca do mundo, etc. Adicionalmente, são explorados tanto métodos de aprendizagem automática como abordagens baseadas em regras, desenvolvendo-se sistemas híbridos capazes de tirar partido das vantagens de cada um destes dois tipos de abordagem.Fundação para a Ciência e a Tecnologia (FCT, SFRH/BD/40140/2007

Time, events and temporal relations: an empirical model for temporal processing of Italian texts

The aim of this work is the elaboration a computational model for the identification of temporal relations in text/discourse to be used as a component in more complex systems for Open-Domain Question-Answers, Information Extraction and Summarization. More specifically, the thesis will concentrate on the relationships between the various elements which signal temporal relations in Italian texts/discourses, on their roles and how they can be exploited. Time is a pervasive element of human life. It is the primary element thanks to which we are able to observe, describe and reason about what surrounds us and the world. The absence of a correct identification of the temporal ordering of what is narrated and/or described may result in a bad comprehension, which can lead to a misunderstanding. Normally, texts/discourses present situations standing in a particular temporal ordering. Whether these situations precede, or overlap or are included one within the other is inferred during the general process of reading and understanding. Nevertheless, to perform this seemingly easy task, we are taking into account a set of complex information involving different linguistic entities and sources of knowledge. A wide variety of devices is used in natural languages to convey temporal information. Verb tense, temporal prepositions, subordinate conjunctions, adjectival phrases are some of the most obvious. Nevertheless even these obvious devices have different degrees of temporal transparency, which may sometimes be not so obvious as it can appear at a quick and superficial analysis. One of the main shortcomings of previous research on temporal relations is represented by the fact that they concentrated only on a particular discourse segment, namely narrative discourse, disregarding the fact that a text/discourse is composed by different types of discourse segments and relations. A good theory or framework for temporal analysis must take into account all of them. In this work, we have concentrated on the elaboration of a framework which could be applied to all text/discourse segments, without paying too much attention to their type, since we claim that temporal relations can be recovered in every kind of discourse segments and not only in narrative ones. The model we propose is obtained by mixing together theoretical assumptions and empirical data, collected by means of two tests submitted to a total of 35 subjects with different backgrounds. The main results we have obtained from these empirical studies are: (i.) a general evaluation of the difficulty of the task of recovering temporal relations; (ii.) information on the level of granularity of temporal relations; (iii.) a saliency-based order of application of the linguistic devices used to express the temporal relations between two eventualities; (iv.) the proposal of tense temporal polysemy, as a device to identify the set of preferences which can assign unique values to possibly multiple temporal relations. On the basis of the empirical data, we propose to enlarge the set of classical finely grained interval relations (Allen, 1983) by including also coarse-grained temporal relations (Freska, 1992). Moreover, there could be cases in which we are not able to state in a reliable way if there exists a temporal relation or what the particular relation between two entities is. To overcome this issue we have adopted the proposal by Mani (2007) which allows the system to have differentiated levels of temporal representation on the basis of the temporal granularity associated with each discourse segment. The lack of an annotated corpus for eventualities, temporal expressions and temporal relations in Italian represents the biggest shortcomings of this work which has prevented the implementation of the model and its evaluation. Nevertheless, we have been able to conduct a series of experiments for the validation of procedures for the further realization of a working prototype. In addition to this, we have been able to implement and validate a working prototype for the spotting of temporal expressions in texts/discourses

Issues in Esahie Nominal Morphology: From Inflection to Word-formation

The present study is a documentation-oriented research which aims at exploring the nominal morphology of Esahie, an otherwise unexplored cross-border Kwa language. Essentially, it examines pertinent inflectional and word formation issues in the nominal domain of Esahie such as noun class system, agreement, syncretism, nominalization, and compounding. The overall goal of this thesis is to investigate and provide a comprehensive account of the attested types, structure, formation, and the lexical semantics of nouns and nominalizations in Esahie. This thesis also seeks to understand what the facts about the structure and formation of nouns and nominalizations in Esahie reveal about the nature of the interface between morphology, phonology, syntax, and semantics, and about the architecture of the grammar in general. In interpreting the Esahie data, we ultimately hope to contribute to current theoretical debates by presenting empirical arguments in support of an abstractive, rather than a constructive view of morphology, by arguing that adopting the formalism of Construction Morphology (CxM, see Booij 2010a-d), as an abstractive model, comes with many advantages. We show that the formalism espoused in CxM is able to deal adequately with all the inflectional and word formation issues discussed in this thesis, including the irregular (non-canonical) patterns which are characterized either by cumulative exponence or extra-compositionality. With regards to compounding, this study confirms the view (cf. Appah 2013; 2015; Akrofi-Ansah 2012b; Lawer 2017) that, in Kwa, notwithstanding the word class of the input elements, the output of a compounding operation is always a nominal. This characterization points to a fascinating (mutual) interplay between the word-formation phenomena of compounding and nominalization, since the former operation invariably feeds into the latter. Overall, this thesis shows that nominalization is a prominent word-formation operation in Kwa grammar. Data used in this thesis emanates from several fieldtrips carried out in some Esahie speaking communities in the Western-North region of Ghana, as well as other secondary sources

Studies in the Morphosyntax of Native and Greek-Origin Verbs

The study clarifies certain details of the Coptic verbal system, such as diathetic classes of labile verbs, semantic classes of non-labile mutable verbs, stative: infinitive opposition, the functional range of the periphrastic construction, integration of Greek loan verbs into Coptic valency alternation system and the role of the loaned morphology in that system. In all these problems, we find manifested the interaction between two grammatical categories, transitivity and aspect. The introductory chapter briefly states the research objectives and gives a general overview of the linguistic material and theory employed. The first chapter studies major regularities in the transitivity alternations of native Egyptian verbs. Defining the Coptic conjugation system by two parameters, aspect and transitivity, I examine the functions of the absolute infinitive as the only unmarked form opposed, on the one hand, to transitive eventive construct forms, and on the other hand, to intransitive stative. The system of conjugation patterns is analyzed as a templatic system where a specific conjugation pattern ascribes not only tense, aspect, and modus, but also voice to an unmarked verbal form. Finally, the native verbs are classified into four groups based on the formal criteria of mutability and lability, and this classification is found to correlate with the semantic one based on the agentivity and telicity of verbal lexemes. I also look into the diachrony of the aspect-transitivity cluster and use the two-parameter model to explain various synchronic anomalies of Coptic verbal valency. The second chapter looks into semantic and grammatical factors triggering the use of the periphrastic pattern which is shown to fulfil the whole range of functions, from punctual passive to resultative, depending on the lexical properties of the verb. The third chapter explores the diathesis of Greek loan verbs in Sahidic. Valency-changing devices for Greek verbs are examined and compared with those operating on native verbs. The occasional use of Greek middle-passive suffix is analyzed as the vestige of parallel system borrowing

Modals, Contextual Parameters, and the Modal Uniformity Hypothesis

There is a common assumption in the semantics of modal auxiliaries in natural language; in utterances of MOD φ , where MOD is a modal and φ is the prejacent, context determines the particular flavor of modality expressed by the modal. Such is the standard contextualist semantics of Kratzer and related proposals. This winds up being a problem, because there is a significant class of modals which have constraints on the admissible modal flavor that are not traceable to context. For example, in MUST φ , subsentential properties of φ, like the aspectual class of the predicate in the prejacent, can affect the flavor of MUST. By encoding the above assumption into the semantics, such contextualist accounts fail to be able to explain, much less to predict, this pattern. Worse yet, attempts to exploit the resources of the theory in service of an explanation run afoul of important commitments of the view, like the hypothesis that modals have a uniform semantics. Given these circumstances, these data might seem like a justification for dispensing with the uniformity hypothesis. The present paper lays out the above problem in detail. Against the pessimistic view, I argue that the the contextualist account can in fact explain and predict these patterns while preserving the uniformity hypothesis. This requires adopting an amendment to the semantics of modals based on the work of Valentine Hacquard. Aside from maintaining the contextualist paradigm and preserving uniformity, the proposal also clarifies the role of context in the interpretation of modals. As it will turn out, the role of context ought to be circumscribed in its flavor-determining role for modals

Evaluative Adjectives as a Window onto Inner-Aspect

162 p.This thesis proposes that Evaluative Adjectives (EAs) (brave, intelligent, rude) are stative causative predicates that undergo the causative alternation just as many verbs do (break). It is argued that EAs syntactic and aspectual properties follow from a single stative causative lexical entry. Analysing EAs¿ aspectual properties leads to the general conclusions that the only primitive aspectual argument denotes a state, and that Davidsonian eventivity is epiphenomenal.EAs are compared with adjectives of psychological experience (eager, willing) and relational adjectives and adjectives denoting physical states (Canadian, tall), as well as verbs of all aspectual sorts. An important result is that adjectival argument structures are shown to be as complex as verbal ones. Argument structure is argued to be neutral with respect to lexical category.EAs are often analysed as Individual-Level predicates. It is shown that EAs only partially overlap with Individual-Level predicates. Rather, they have a distinct aspectual signature matching verbs classified as Davidsonian-States and stative causatives. In arguing against an IL classification of EAs an extensive argument against the Individual/Stage distinction is given.It is argued that cross-linguistically the only aspectual distinction made in the syntax through predicate decomposition is between states and causatives built out of states. Eventivity effects are derivative of causation, and ultimately pragmatic. The conclusion is that EAs and causative alternating verbs such as break have the same formal aspectual representations
