description Publicationkeyboard_double_arrow_right Doctoral thesis , Thesis 2016 FrancePublisher:figshare Authors: Saad, Motaz;Saad, Motaz;The aim of this thesis is to study sentiments in comparable documents. First, we collect English, French and Arabic comparable corpora from Wikipedia and Euronews, and we align each corpus at the document level. We further gather English-Arabic news documents from local and foreign news agencies. The English documents are collected from BBC website and the Arabic document are collected from Al-jazeera website. Second, we present a cross-lingual document similarity measure to automatically retrieve and align comparable documents. Then, we propose a cross-lingual sentiment annotation method to label source and target documents with sentiments. Finally, we use statistical measures to compare the agreement of sentiments in the source and the target pair of the comparable documents. The methods presented in this thesis are language independent and they can be applied on any language pair.; L'objectif de cette thèse est d'étudier les sentiments dans les documents comparables. Premièr\-ement, nous avons recueillis des corpus comparables en anglais, français et arabe de Wikipédia et d’Euronews, et nous avons aligné ces corpus au niveau document. Nous avons en plus collecté des documents d’informations des agences de presse locales et étrangères dans les langues anglaise et arabe. Les documents en anglais ont été recueillis du site de la BBC, ceux en arabe du site d’Al-Jazzera. Deuxièmement, nous avons présenté une mesure de similarité coss-linguistique des documents dans le but de récupérer et aligner automatiquement les documents comparables. Ensuite, nous avons proposé une méthode d’annotation cross-linguistique en termes de sentiments, afin d’étiqueter les documents source et cible avec des sentiments. Enfin, nous avons utilisé des mesures statistiques pour comparer l'accord des sentiments entre les documents comparables source et cible. Les méthodes présentées dans cette thèse ne dépendent pas d’une paire de langue bien déterminée, elles peuvent être appliquées sur toute autre couple de langue.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Bachelor thesis , Doctoral thesis , Other literature type 2012 United KingdomPublisher:figshare Authors: Ruddy, Mark;Ruddy, Mark;The water vole is common in Middle and Late Pleistocene temperate Palaearctic faunas. It is widely used in biostratigraphy because of tem- poral trends in the size, shape and structure of the first lower molar (M1). However, geographic variation in the evolutionary development of the M1 has restricted the precision and accuracy of age-estimations. This thesis explores morphological variation in the M1 of fossil and extant populations of the lineage Mimomys savini–Arvicola, and uses the phenotype and the genotype to develop evolutionary hypotheses. Geometric and traditional morphometric methods are used to quantify tooth shape and enamel thickness from over 4000 digital photographs of M1s taken from specimens originating from 146 modern and fossil groups across the western Palaearctic. M1s are photographed to ob- tain a true cross-section, giving a more accurate description of molar shape. Morphological variation is explored in terms of sample-size, taphonomy, and ontogeny. Sample sizes of less than 10 are likely to provide inaccurate summary statistics of morphometric variables but depositional type appears to have no systematic effect on within-group variation. Change in the morphology of M1s through ontogeny is an im- portant source of morphological variation, explaining up to 29% of mo- lar shape within-specimens and up to 95% of enamel thickness within enamel layers of specimens. Removal of ontogenetic variation from mo- lar shape improves congruence between morphological and molecular data, indicating age-corrected variables should be used when assessing evolutionary patterns. Temporal and spatial patterns in the enamel thickness quotient (SDQ), based on age-corrected enamel thicknesses, mirror those from published data but differ in some details. Method- ological differences mean absolute SDQ values cannot be compared. Qualitative patterns include a large decrease in SDQ across MIS 12 and a steep east–west morphocline during the late Middle Pleistocene.
