Title: Joining segments in Czech sentences Author: Bc. Josef Čech Department: Institute of Formal and Applied Linguistics Supervisor: doc. RNDr. Vladislav Kuboň Ph.D. e-mail: vk@ufal.mff.cuni.cz Abstract: This thesis follows up segmentation of complex sentences to linguistic motivated objects - segments - and their mutual relations. These relations can be used for next work with segments. Main purpose for mapping relations is their joining into next level unit - clause. Theoretically should be possible to analyse each clause of complex sentence separately. Analysis of set of clauses should be quicker than of analysis whole complex sentence. Segments should be found thanks to linguistic separators and rule approach. Rule approach proves in problem relations between neighbouring segments. This thesis should attest that rule approach is best solution for joining segments into clauses. Position tag of segment was part of this thesis. This tag should be used in methods dealing with segments instead of custom segment. Keyword: segment, clause, tag, joining segments, syntactic analysis

O presente trabalho levanta a questão da derivação sintática em diferentes contruções de tópico. Essa diferenciação foi estabelecida por Frascarreli & Hinterhölzl (2007) com base na abordagem de Rizzi (1997) que propõe uma estrutura mais articulada para o complexo CP. Assim Frascarelli & Hinterhölzl (2007) realizam um levantamento de corpora determinando três tipos de tópico em sentenças do italiano e do alemão, a saber: a) Tópico conversacional (aboutness topic): informação que é o tema da sentença (REINHART, 1981); b) Tópico contrastivo: constituinte que cria um par opositivo a outro tópico (CHAFE, 1987) c) Tópico familiar: constituinte acessível, geralmente realizado em uma forma pronominal (PESETSKY, 1987). Para dar uma ideia do problema considere os exemplos, abaixo: 1) O JOÃO (*ele) leu o livro de sintaxe (não o Pedro). Foco contrastivo 2) O livro de sintaxe, o João leu ø/ele ontem. Tópico 3) O João, ele leu o livro de sintaxe. Tópico 4) O João, ø leu o livro de sintaxe ontem. Tópico Os autores avaliam o contorno entoacional de cada uma das construções (2 e 3) e a sentença (4) que coloca uma ambiguidade estrutural entre moviemnto e geração na base. Os autores, então, propõem que todas sejam geradas na base deixando a estrutura de cujo sintagma é inequivocamente movido para a expressão de foco, sentença (1). Com base nesse trabalho realizamos um estudo comparativo entre as estruturas de tópico em PB. Contrapomos a entoação de sentenças como as decritas acima e avaliamos se existe um melhor tratamento sintático para tais estruturas, seja derivação via movimento, ou geração na base. No primeiro capítulo apresentamos o problema e a arquitetura da fonética articulatória, autossegmental e métrica e prosódica que embasam o estudo. Em seguida apresentamos alguns estudos já realizados nessa matéria que contam com a descrição prosódica de sentenças neutras do PB e sentenças com foco prosódico sobre o sujeito, além de sentenças com tópicos já levantadas em pesquisas anteriores. No segundo capítulo apresentaremos a teoria sintática que ampara nosso entendimento das estruturas envolvidas e o tipo de derivação em jogo. A teoria gerativa formulada por Chomsky servirá como guia balizador da derivação, especialmente a partir do programa minimalista (COMSKY 1995 e posteriores) Após essa introdução aprsentaremos algns estudos sobre esse conjunto de sentenças os possíveis caminhos a serem seguidos. No terceiro capítulo descrevemos o experimento, no quarto apresentamos e discutimos os resultados. Por fim, o quinto e último capítulo oferece um panorama geral do que foi exposto e as conclusões. / This study is about different topic constructions and their darivations. This differentiation was established by Frascarreli & Hinterhölzl (2007) based on the approach developed by Rizzi (1997), which proposes a more articulated CP structure. So Frascarelli & Hinterhölzl (2007) conducted corpora syrvey and unveal three types of topics in the Italian and German: a) shifting topic (aboutness topic): information that is the subject of the sentence, relativaly (Reinhart, 1981); b) contrastive topic: a phrase that creates a opposition to another pharse (Chafe, 1987) c) familiar topic: a given or accessable constituint (PESETSKY, 1987). To give an ideato this problem, please, consider the examples, below: 1) JOHN (* he) reads the syntax book (not Peter). Contrastive focus 2) The syntax book, John read ø / it yesterday. Topic 3) John, he read the syntax book. Topic 4) John ø syntax read the book yesterday. Topic These sentences ar all fine in BP. Sentence (1) can not have the strong pronoun. Sentence (2) is accetable in both forms either with a strong pronoun or wth the empity category. Sentence (3) is accetable because John is based generated at spell out. Sentence (4) is ambiguous bettween movment or base generation. The authors evaluate the intonation of each one of the structures like (2, 3 and 4) and propose that: they are all based generated leaving the derivation via movment to express focus, sentence (1). Based on this work, we carried out a comparative study of the topic structures in BP. Analizing sentences like (2-4) we stabilishs the intonational contour of them and look for a better treatment for such syntactic structures: derivation via movement, or base generation. In the very first chapter we present the problem and the architecture of the phonetic articulation, the autossegmental and metric phonology and prosodic structure that will guide this study. Then, some previous studies in this area are show wtih the descriptions of the PB neutral sentences and sentences with prosodic focus on the subject, and, also, sentences with already raised topics in the recent past. In the second chapter, we will present the syntactic theory that supports our understanding of the structures involved here and the type of analisys envolved. The generative theory formulated by Chomsky will serve as base line, especially from the Minimalist Program (COMSKY 1995 and laters). After this introduction, we will present some findings on this set of sentences and two possible paths to follow. In the third chapter we describe the experiment, in the fourth we present and discuss the results. Finally, the fifth and final chapter offers an overview of the foregoing and the conclusions.

Thesis (M. A. (African Languages)) -- University of Limpopo, 2002 / Refer to the document

A large proportion of computationally-oriented theories of grammar operate within the confines of monostratality (i.e. there is only one level of syntactic analysis), compositionality (i.e. the meaning of an expression is determined by the meanings of its syntactic parts, plus their manner of combination), and adjacency (i.e. the only operation on terminal strings is concatenation). This thesis looks at two major approaches falling within these bounds: that based on phrase structure grammar (e.g. Gazdar), and that based on categorial grammar (e.g. Steedman). The theories are examined with reference to extraction and coordination constructions; crucially a range of 'compound' extraction and coordination phenomena are brought to bear. It is argued that the early phrase structure grammar metarules can characterise operations generating compound phenomena, but in so doing require a categorial-like category system. It is also argued that while categorial grammar contains an adequate category apparatus, Steedman's primitives such as composition do not extend to cover the full range of data. A theory is therefore presented integrating the approaches of Gazdar and Steedman. The central issue as regards processing is derivational equivalence: the grammars under consideration typically generate many semantically equivalent derivations of an expression. This problem is addressed by showing how to axiomatise derivational equivalence, and a parser is presented which employs the axiomatisation to avoid following equivalent paths.

This thesis concerns a dilemma of multi-lingual web applications. The document describes some general solutions while suggesting such applications, however first of all it is aimed for information system VUT and its enlargement for translation administration. The text contains structural description of this system and instruments used during its development, but especially it defines system requirements of programming engineers and translators, describes and evaluates new language versions solution and there are possibilities of contingent extensions considered at the conclusion of my thesis.

This study develops a new approach to agreement variation in Standard Arabic (SA) and Rural Jordanian Arabic (RJA) based on the Probe-Goal framework of Chomsky (2000, 2001). The key patterns investigated are the variation in fullness of agreement in the SV and VS word orders, the relationship between agreement and clitic doubling, and the patterning of agreement with conjoined subjects. The thesis argues for a connection between agreement, clitic doubling, and word order. Full agreement on T (in person, number, and gender) causes the subject to move to [Spec, TP], deriving SV order. However, partial agreement on T (lacking person) creates only a partial copy of the subject in [Spec, TP]. This partial copy is realized as a pronominal clitic in some contexts (giving CLsVS word order) and as null pro in other contexts (giving VS word order). This approach enables a unified account of various differences in the patterning of agreement in SA and RJA. Turning to the more complex case of agreement with conjoined subjects, both varieties exhibit full resolved agreement with preverbal conjoined subjects. With postverbal conjoined subjects, however, there is variation: SA allows only partial agreement with the first conjunct while RJA allows partial agreement either with the first conjunct or with the entire conjoined phrase, depending on the features and the order of the conjoined nominals. The Probe-Goal framework augmented with Multiple Agree and the Continuity condition (Nevins 2007, 2011) will be employed to account for the choice between these two options in RJA. The more general theoretical conclusion is that the variation in agreement patterns is constrained by the internal hierarchical structure of φ-features on the probe. I propose that the probe has the same hierarchical structure as a pronoun (i.e. a DP). This proposal makes predictions about the range of possible variation in the features that are active in agreement and connects to broader issues such as the Pronominal Argument Hypothesis (Jelinek 1984) and the diachronic relationship between pronouns and agreement markers. / May 2017

Automatic syntactic analysis is essential for extracting useful information from large-scale learner data for linguistic research and natural language processing (NLP). Currently, researchers use standard POS taggers and parsers developed on native language to analyze learner language. Investigation of how such systems perform on learner data is needed to develop strategies for minimizing the cross-domain effects. Furthermore, POS taggers and parsers are developed for generic NLP purposes and may not be useful for identifying specific syntactic constructs such as subcategorization frames (SCFs). SCFs have attracted much research attention as they provide unique insight into the interplay between lexical and structural information. An automatic SCF identification system adapted for learner language is needed to facilitate research on L2 SCFs. In this thesis, we first provide a comprehensive evaluation of standard POS taggers and parsers on learner and native English. We show that the common practice of constructing a gold standard by manually correcting the output of a system can introduce bias to the evaluation, and we suggest a method to control for the bias. We also quantitatively evaluate the impact of fine-grained learner errors on POS tagging and parsing, identifying the most influential learner errors. Furthermore, we show that the performance of probabilistic POS taggers and parsers on native English can predict their performance on learner English. Secondly, we develop an SCF identification system for learner English. We train a machine learning model on both native and learner English data. The system can label individual verb occurrences in learner data for a set of 49 distinct SCFs. Our evaluation shows that the system reaches an accuracy of 84\% F1 score. We then demonstrate that the level of accuracy is adequate for linguistic research. We design the first multidimensional SCF diversity metrics and investigate how SCF diversity changes with L2 proficiency on a large learner corpus. Our results show that as L2 proficiency develops, learners tend to use more diverse SCF types with greater taxonomic distance; more advanced learners also use different SCF types more evenly and locate the verb tokens of the same SCF type further away from each other. Furthermore, we demonstrate that the proposed SCF diversity metrics contribute a unique perspective to the prediction of L2 proficiency beyond existing syntactic complexity metrics.
