Book excerpt: "La disponibilité d'outils intelligents d'exploration de données est vitale pour aider à explorer et à comprendre les textes historiques (anciens). Dans cette thèse, nous présentons le contexte de recherche et l'étude de faisabilité d'une plateforme offrant un outil illustratif d'aide à la décision basé sur les graphiques. Ces derniers permettent aux experts de détecter facilement les liens entre les multiples aspects présentés dans le texte. En tant que tel, la plateforme est un outil auto-évolutif, interconnectant les données par leurs aspects et dépendances. Un modèle d'exploration de texte à été proposé, se modèle combine à la fois des méthodes de l'apprentissage non-supervisé et l'apprentissage supervisé. Il est basé principalement sur l'approche TF-IDF, l'algorithme K-Moyennes (non-supervisé) et le réseau de neurones (supervisé). L'approche TF-IDF permet de tranformer l'ensemble de documents en une représentation vectorielle. L'algorithme K-Moyenne est ulitié pour faire le regroupemenrt de données (la création de groupe à partir de l'ensemble de documents suivant une certaine simulitude). Le réseau de neurone utilise la liste des documents regroupés par le K-Moyenne comme une liste d'apprentissage, après l'opération d'apprentissage il est capable de prédire la classe adéquate pour un nouveau document. L'utilisateur peut étendre la base de données en ajoutant de nouvels aspects par exemple. La plateforme est une application Web extensible. Nous proposons de combiner plusieurs outils, principalement Java et PhP. Cette plateforme combine le réseau de neurones dans l'exploration de données et l'algorithmes TF-IDF pour analyser et filtrer le contenu du texte. La conception de notre approche est discutée et détaillée. Des remarques importantes ont été tirées à la fin de cette thèse, ces remarques ouvrent la porte à l'application de l'apprentissage profond pour accomplir les tâches nécessaires du processus de développement de la plateforme.

Available in PDF, EPUB and Kindle. Book excerpt: LA THESE PORTE SUR L'UTILISATION DE METHODES ISSUES DE L'APPRENTISSAGE AUTOMATIQUE POUR DES TACHES DE RECHERCHE D'INFORMATION DANS LES TEXTES. NOTRE MOTIVATION A ETE D'EXPLORER LE POTENTIEL DES TECHNIQUES D'APPRENTISSAGE POUR REPONDRE AUX DEMANDES D'ACCES A L'INFORMATION TEXTUELLE LIEES AU DEVELOPPEMENT DE GRANDES BASES DE DONNEES TEXTE ET AU WEB. DANS CE CONTEXTE IL EST DEVENU IMPORTANT D'ETRE CAPABLE DE TRAITER DE GRANDES QUANTITES DE DONNEES, D'APPORTER DES SOLUTIONS DIVERSIFIEES AUX NOUVELLES DEMANDES DES UTILISATEURS, ET D'AUTOMATISER LES OUTILS QUI PERMETTENT D'EXPLOITER L'INFORMATION TEXTUELLE. NOUS AVONS POUR CELA EXPLORE DEUX DIRECTIONS. LA PREMIERE EST LE DEVELOPPEMENT DE MODELES PERMETTANT DE PRENDRE EN COMPTE L'INFORMATION SEQUENTIELLE PRESENTE DANS LES TEXTES AFIN D'EXPLOITER UNE INFORMATION PLUS RICHE QUE LA REPRESENTATION SAC DE MOTS TRADITIONNELLEMENT UTILISEE PAR LES SYSTEMES DE RECHERCHE D'INFORMATION. POUR CELA NOUS PROPOSONS DES MODELES STATISTIQUES BASES SUR DES MODELES DE MARKOV CACHES ET DES RESEAUX DE NEURONES. NOUS MONTRONS COMMENT CES SYSTEMES PERMETTENT D'ETENDRE LES CAPACITES DES MODELES PROBABILISTES CLASSIQUES DE LA RECHERCHE D'INFORMATION ET COMMENT ILS PEUVENT ETRE UTILISES EN PARTICULIER POUR DES TACHES D'EXTRACTION D'INFORMATION DE SURFACE. LA DEUXIEME DIRECTION EXPLOREE CONCERNE L'APPRENTISSAGE SEMI-SUPERVISE. IL S'AGIT D'UTILISER POUR DES TACHES D'ACCES A L'INFORMATION UNE PETITE QUANTITE DE DONNEES ETIQUETEES CONJOINTEMENT A UNE MASSE IMPORTANTE DE DONNEES NON ETIQUETEES. CELA CORRESPOND A UNE SITUATION DE PLUS EN PLUS FREQUENTE EN RECHERCHE D'INFORMATION. NOUS PROPOSONS ET ANALYSONS DES ALGORITHMES ORIGINAUX BASES SUR UN FORMALISME DISCRIMINANT. NOUS AVONS UTILISE CES TECHNIQUES POUR LE RESUME DE TEXTE VU SOUS L'ANGLE DE L'EXTRACTION DE PHRASES PERTINENTES D'UN DOCUMENT. CES TRAVAUX SE SONT CONCRETISES PAR LE DEVELOPPEMENT DU SYSTEME D'AIDE AU RESUME AUTOMATIQUE (S.A.R.A.).

This book was released on 1992 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA POLYSEMIE EST PEUT-ETRE L'UN DES PLUS SERIEUX PROBLEMES AUXQUELS SONT CONFRONTES LES CHERCHEURS EN TRAITEMENT AUTOMATIQUE DE LA LANGUE. LORS DE LA COMPREHENSION D'UN TEXTE, IL EST NECESSAIRE DE DISPOSER D'INFORMATIONS EXTRA-TEXTUELLES. CES INFORMATIONS SE RAPPROCHENT DES DONNEES ENCYCLOPEDIQUES ET REPRESENTENT LES CONNAISSANCES GLOBALES D'UN INDIVIDU SUR LE MONDE. DE NOMBREUSES THEORIES ONT PROPOSE DES STRUCTURES DE DONNEES PERMETTANT DE LES REPRESENTER FORMELLEMENT. LA THEORIE DES GRAPHES CONCEPTUELS UNIFIE ET GENERALISE UN NOMBRE IMPORTANT DES METHODES UTILISEES POUR REPRESENTER LE SENS. L'OBJET DU TRAVAIL A DONC ETE DE RENDRE OPERATIONNELLE CETTE THEORIE ET DE L'UTILISER POUR LA LEVEE D'AMBIGUITE. NOUS AVONS INTRODUIT POUR CELA UNE REPRESENTATION DES CONNAISSANCES SOUS LA FORME D'HYPERGRAPHES. NOUS MONTRONS QUE LES OPERATIONS DE BASE SUR LES GRAPHES CONCEPTUELS DECOULENT D'UNE OPERATION D'INTERSECTION MAXIMALE ENTRE DEUX HYPERGRAPHES. AUSSI MNOUS SOMMES NOUS ATTACHES A DEFINIR UN ALGORITHME OPTIMISE POUR LA CALCULER. DANS NOTRE METHODE DE LEVEE D'AMBIGUITE, LES SENS DU TEXTE A ANALYSER, AINSI QUE LES CONTEXTES LIES AU DOMAINE, SONT REPRESENTES SOUS LA FORME D'HYPERGRAPHES CONCEPTUELS. LA LEVEE D'AMBIGUITE CONSISTE A TROUVER LA PAIRE SENS-CONTEXTE POUR LAQUELLE UN COEFFICIENT DE RECOUVREMENT, QUE NOUS AVONS DEFINI, EST OPTIMAL. NOUS PROPOSONS EGALEMENT UN APPRENTISSAGE AUTOMATIQUE DE CONTEXTES A L'AIDE DE L'ANALYSE DE PLUSIEURS TEXTES. L'APPRENTISSAGE PROCEDE EN GENERALISANT ET EN VERIFIANT LES CONNAISSANCES CONTENUES DANS LES DIFFERENTS CONTEXTES. LES METHODES PRESENTEES SONT ENCOURAGEANTES ET LAISSENT ENTREVOIR DE NOMBREUSES APPLICATIONS QUANT A LA RECONNAISSANCE DES FORMES EN GENERAL ET A LA LEVEE D'AMBIGUITE EN PARTICULIER. EN EFFET, LA PLUPART DES REPRESENTATIONS CHOISIES A L'HEURE ACTUELLE POUR REPRESENTER LES CONNAISSANCES SONT ESSENTIELLEMENT BASEES SUR LA THEORIE DES GRAPHES. NOS ALGORITHMES, BIEN QUE DEVELOPPES POUR LES GRAPHES CONCEPTUELS, PEUVENT AUSSI S'APPLIQUER A DES DOMAINES BEAUCOUP PLUS VARIES ET RESTENT ASSEZ GENERAUX POUR PERMETTRE DE RESOUDRE D'AUTRES PROBLEMES

Download or read book The Planetarium written by Nathalie Sarraute and published by Deep Vellum Publishing. This book was released on 2023-01-31 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: A young writer has his heart set on his aunt's large apartment. With this seemingly simple conceit, the characters of The Planetarium are set in orbit and a galaxy of argument, resentment, and bitterness erupts. Telling the story from various points of view, Sarraute focuses below the surface, on the emotional lives of the characters in a way that surpasses even Virginia Woolf. Always deeply engaging, The Planetarium reveals the deep disparity between the way we see ourselves and the way others see us.

Download or read book Memoirs of an Egotist written by Stendhal and published by Read Books Ltd. This book was released on 2021-03-22 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the memoirs of Stendahl or in his own words the 'chatter about his private life' between 1821 and 1830. It was between these dates that he moved to Paris and here looks back on his life as an eccentric bachelor. 'As well as Beyle the clairvoyant self-investigator, the sardonic analyst of Parisian salon society and deliberate cultivator of wit, here emerges Beyle the despairing lover, the shakespearean enthusiast, whose romantic sentiment run always parallel with his eighteenth-century logic'. Marie-Henri Beyle - better-known by his pen name, Stendhal - was born in Grenoble, France in 1783. He turned to writing after the final defeat of Napoleon in 1815, notable works include A Life of Rossini (1824), A Life of Napoleon (1929) and The Red and the Black published in 1830. A number of works were published posthumously, including Lamiel (1889), Memoirs of an Egotist (1892) and Lucien Leuwen (1894). Stendhal is now regarded as one of the earliest and foremost practitioners of literary realism.
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
