Syntactic, semantic and FSP aspects of ditransitive complementation: a study of give, lend, send, offer and show
Brůhová, Gabriela ; Dušková, Libuše (advisor) ; Hajičová, Eva (referee) ; Šaldová, Pavlína (referee)
The subject of the present study is an analysis of five ditransitive verbs: give, lend, send, offer and show. The study focuses on the position of the two objects and on the factors that have an impact on the object ordering. An attempt is here made to provide a systematic overview of the position of the two objects with respect to their realization (i.e. substantival or pronominal). As regards the realization of the two objects, four types are distinguished: i. both Oi /Oprep and Od realized by nouns; ii. both Oi /Oprep and Od realized by pronouns; iii. Oi /Oprep realized by a noun and Od by a pronoun; iv. Oi /Oprep realized by a pronoun and Od by a noun. The position of the objects is assumed to be associated with the distribution of communicative dynamism or in other words with the principle of end-focus, i.e. that given information tends to precede new information. The second principle that operates in the ordering the two objects is the principle of end-weight. Of the three (or four, including intonation) factors whose interplay determines the FSP function of a clause element, in the case of ditransitive complementation the most important role is played by the contextual factor. Therefore, particular attention is paid to the context-dependence / independence of the two objects. The present...

Extended nominal coreference and bridging anaphora (an approach to annotation of Czech data in Prague dependency treebank)
Nedoluzhko, Anna ; Uličný, Oldřich (advisor) ; Hajičová, Eva (referee) ; Oliva, Karel (referee)
The dissertation presents one of the possible models of processmg extended textual coreference and bridging anaphora in a large textual corpora, which we then use for annotation of certain relations in texts of the Prague Oependency Treebank (POT). Based, on the one hand, on the literature concerning the theory of reference, discource and some findings of theoretical linguistics, and, on the other hand, using the existing methodology of annotations, we created a detailed classification of textual coreferential relations and types of bridging anaphora. Within textual coreference, we distinguish between two types of textual coreferential relations - coreferential relations between noun phrases with specific reference and coreferential relation between noun phrases with non-specific, primarily generic, reference. We determined six types of relations for bridging anaphora: relation PART- between part and whole; relation SUBSET - between a set and a subset or element of a set; FUNCT - between an object and a unique function on that entity; CONTRAST- between semantíc and contextual opposites; relation ANAF of anaphorical referencing between noncoreferencial objects; REST- for other examples of bridging anaphora. One of the goals of the research is to create a system of theoretical principals that would be used...

Discourse Relations in Czech
Poláková, Lucie ; Hajičová, Eva (advisor) ; Hoffmannová, Jana (referee) ; Pešek, Ondřej (referee)
This doctoral thesis is devoted to linguistic analysis of discourse relations as one of the aspects of discourse coherence. Discourse relations are semantic relations holding between propositions in a discourse (discourse arguments). The aim of the thesis is a complex description of discourse relations in Czech and its application in an annotation scheme in the Prague Dependency Treebank. The thesis is divided into three parts: The first one is focused on the theoretical description of discourse relations and on analysis of adequacy of various methodological concepts in corpus processing. The second part describes in detail the proposed scheme for the annotation of discourse relations and the process of the corpus build- up including the evaluation of consistency of the annotated data. Finally, in the last part of the thesis, we address some problematic issues arisen with the employment the proposed scheme and look for their possible solutions.

Particle Character Units and Their Function in Text Structure, especially in Topic- Focus Articulation
Štěpánková, Barbora ; Hajičová, Eva (advisor) ; Panevová, Jarmila (referee) ; Pešek, Ondřej (referee)
B. Štěpánková K funkci výrazů částicové povahy ve výstavbě textu... ABSTRACT This dissertation is devoted to a specific type of particle unit which we refer to as the actualizer. Actualizers are differentiated from other particles primarily due to a combination of the following properties: the ability to imply a presupposition and the ability to actualize or emphasize a nearby expression. They play an important role in the topic-focus articulation of a sentence by drawing attention to elements with a greater degree of communicative dynamism, not only in focus or contrastive topic, but also in other parts of the sentence. Unlike previous studies which have concentrated mainly on prototypical representatives of these units, this dissertation tries to capture the greatest possible number of actualizers. At the same time, it aims to describe their semantic characteristics, and based on this, it attempts to categorize actualizers into three semantic groups. From this perspective, we can distinguish between restrictive, inclusive, and temporally emphasizing actualizers. These groups can be further divided according to their specific features. The dissertation also analyzes the possible positioning of the actualizers in various places in a sentence and investigates which expressions can occur in the surroundings...

Rules for analyzing anaphora in Czech
Nguy, Giang Linh ; Hajič, Jan (advisor) ; Hajičová, Eva (referee)
With the increasing importance of natural language processing there is growing number of research with the theme automatic anaphora resolution.. The contribution to the research on this problem is also this thesis. The aim of the work is to propose a set of rules for anaphora resolution in Czech. The created set of rules consists of handwritten rules as well as rules developped with the aid of machine learning system C4.5. For the rules training and testing were used anoted data from the Prague Dependency Treebank, in which following types of anaphora are captured: pronominal anaphora, control, reciprocity and dependency relation of adjuncts. Our work is focused on these types of anaphora. The evaluation of the rules is done with standard methods for interpretation of recall and precision.

Non-projectivity in English and Czech
Čermáková, Kristýna ; Hajičová, Eva (advisor) ; Malá, Markéta (referee)
This thesis analyzes non-projective constructions in English and Czech. It is based on the functional generative description of language and the analysis of material drawn from the Prague Czech-English Dependency Treebank, the Prague Dependency Treebank, and the British National Corpus. The theoretical part provides a brief characterization of phrase structure grammar and dependency grammar together with the definition of the fundamentals of the functional generative description, and the definition of non-projectivity. The analytical section presents a detailed comparative classification of non-projective structures in both languages. Individual types are studied from the perspective of differences between the surface structure and the underlying structure, demonstrating how the substitution of a non-projective clause for a projective one influences the topic-focus articulation and the meaning of the clause. The main objective is to define factors motivating non-projectivity in English and Czech, to compare them, and to determine whether it is marked or neutral type of discontinuity that prevails in each of the two languages.

On the Linguistic Structure of Emotional Meaning in Czech
Veselovská, Kateřina ; Hajičová, Eva (advisor) ; Petkevič, Vladimír (referee) ; Smrž, Pavel (referee)
Title: On the Linguistic Structure of Emotional Meaning in Czech Author: Mgr. Kateřina Veselovská Department: Institute of Formal and Applied Linguistics Supervisor: Prof. PhDr. Eva Hajičová, DrSc., Institute of Formal and Applied Linguistics Keywords: emotional meaning, linguistic structure, sentiment analysis, opinion mining, evaluative language Abstract: This thesis has two main goals. First, we provide an analysis of language means which together form an emotional meaning of written utterances in Czech. Sec- ond, we employ the findings concerning emotional language in computational applications. We provide a systematic overview of lexical, morphosyntactic, semantic and pragmatic aspects of emotional meaning in Czech utterances. Also, we propose two formal representations of emotional structures within the framework of the Prague Dependency Treebank and Construction Grammar. Regarding the computational applications, we focus on sentiment analysis, i.e. automatic extraction of emotions from text. We describe a creation of manually annotated emotional data resources in Czech and perform two main sentiment analysis tasks, polarity classification and opinion target identification on Czech data. In both of these tasks, we reach the state-of-the-art results.
