Understanding comparative questions and retrieving argumentative answers
Making decisions is an integral part of everyday life, yet it can be a difficult and complex process. While peoplesā wants and needs are unlimited, resources are often scarce, making it necessary to research the possible alternatives and weigh the pros and cons before making a decision. Nowadays, the Internet has become the main source of information when it comes to comparing alternatives, making search engines the primary means for collecting new information. However, relying only on term matching is not sufficient to adequately address requests for comparisons. Therefore, search systems should go beyond this approach to effectively address comparative information needs. In this dissertation, I explore from different perspectives how search systems can respond to comparative questions. First, I examine approaches to identifying comparative questions and study their underlying information needs. Second, I investigate a methodology to identify important constituents of comparative questions like the to-be-compared options and to detect the stance of answers towards these comparison options. Then, I address ambiguous comparative search queries by studying an interactive clarification search interface. And finally, addressing answering comparative questions, I investigate retrieval approaches that consider not only the topical relevance of potential answers but also account for the presence of arguments towards the comparison options mentioned in the questions. By addressing these facets, I aim to provide a comprehensive understanding of how to effectively satisfy the information needs of searchers seeking to compare different alternatives

Ambiguity and entropy in the process of translation and post-editing
This thesis analyses the way in which ambiguity is cognitively processed, in translation in general and post-editing in particular, drawing inferences from psycholinguistics, bilingualism, and entropy-based models of translation cognition. Conceptually, it assumes non-selective activation of both languages (source and target) in the translation process, and explores how entropy and entropy reduction can theoretically describe assumed mental states during disambiguation. Empirically, it uses a product-based metric of word translation entropy (HTra), and eye-movement and keystroke data from the CRITT Translation Process Research Database, to shed light on how the conceptual understanding of lexical and structural ambiguity may be manifested by observable behaviour. At the lexical level, examination of behavioural data pertaining to a high-HTra item from 217 participants translating/post-editing from English into multiple languages shows that the item tends to result in pauses in production and regression of eye movements, and that the translatorsā/post-editorsā corresponding scrutinization of the source text (ST) tends to involve a visual search for lower-HTra words in the co-text and, accordingly, a decrease in the average entropy of the activity unit. Regarding syntax, a Chinese relative clause in the machine translation output, which can involve a garden-path effect, is examined in terms of eye movements from 18 participants. Results show that, contrary to monolingual reading, disruptions of processing tend to occur not in the later part of the sentence where the wrong parse is disconfirmed, but in the earlier regions where the most quickly-built analysis is semantically inconsistent with the ST. Structural disambiguation and re-analysis seem to be bypassed. This suggests that, on the one hand, reading for post-editing receives a strong biasing effect from the ST, and on the other, argument integration is more appropriately explained from an incremental processing perspective rather than a head-driven approach, as thematic roles seem to be assigned immediately in reading for post-editing. While the lexical analysis supports a parallel disambiguation model, the structural analysis seems to support a serial one. In terms of translation models, both emphasize the impact of cross-linguistic priming and the presence of considerable horizontality in the translation process

Examining university student satisfaction and barriers to taking online remote exams
Recent years have seen a surge in the popularity of online exams at universities, due to the greater convenience and flexibility they offer both students and institutions. Driven by the dearth of empirical data on distance learning students' satisfaction levels and the difficulties they face when taking online exams, a survey with 562 students at The Open University (UK) was conducted to gain insights into their experiences with this type of exam. Satisfaction was reported with the environment and exams, while work commitments and technical difficulties presented the greatest barriers. Gender, race and disability were also associated with different levels of satisfaction and barriers. This study adds to the increasing number of studies into online exams, demonstrating how this type of exam can still have a substantial effect on students experienced in online learning systems and

Head-Driven Phrase Structure Grammar
Head-Driven Phrase Structure Grammar (HPSG) is a constraint-based or declarative approach to linguistic knowledge, which analyses all descriptive levels (phonology, morphology, syntax, semantics, pragmatics) with feature value pairs, structure sharing, and relational constraints. In syntax it assumes that expressions have a single relatively simple constituent structure. This volume provides a state-of-the-art introduction to the framework. Various chapters discuss basic assumptions and formal foundations, describe the evolution of the framework, and go into the details of the main syntactic phenomena. Further chapters are devoted to non-syntactic levels of description. The book also considers related fields and research areas (gesture, sign languages, computational linguistics) and includes chapters comparing HPSG with other frameworks (Lexical Functional Grammar, Categorial Grammar, Construction Grammar, Dependency Grammar, and Minimalism)
Language is a complex adaptive system
The ASLAN labex - Advanced studies on language complexity - brings together a unique set of expertise and varied points of view on language. In this volume, we employ three main sections showcasing diverse empirical work to illustrate how language within human interaction is a complex and adaptive system. The first section ā epistemological views on complexity ā pleads for epistemological plurality, an end to dichotomies, and proposes different ways to connect and translate between frameworks. The second section ā complexity, pragmatics and discourse ā focuses on discourse practices at different levels of description. Other semiotic systems, in addition to language are mobilized, but also interlocutorsā perception, memory and understanding of culture. The third section ā complexity, interaction, and multimodality ā employs different disciplinary frameworks to weave between micro, meso, and macro levels of analyses. Our specific contributions include adding elements to and extending the field of application of the models proposed by others through new examples of emergence, interplay of heterogeneous elements, intrinsic diversity, feedback, novelty, self-organization, adaptation, multi-dimensionality, indeterminism, and collective control with distributed emergence. Finally, we argue for a change in vantage point regarding the search for linguistic universals
Proceedings of the VIIth GSCP International Conference
The 7th International Conference of the Gruppo di Studi sulla Comunicazione Parlata, dedicated to the memory of Claire Blanche-Benveniste, chose as its main theme Speech and Corpora. The wide international origin of the 235 authors from 21 countries and 95 institutions led to papers on many different languages. The 89 papers of this volume reflect the themes of the conference: spoken corpora compilation and annotation, with the technological connected fields; the relation between prosody and pragmatics; speech pathologies; and different papers on phonetics, speech and linguistic analysis, pragmatics and sociolinguistics. Many papers are also dedicated to speech and second language studies. The online publication with FUP allows direct access to sound and video linked to papers (when downloaded)
