La fouille de textes (text mining) comme outil de création automatique de réseaux génétiques. Avec l’amélioration constante de la vitesse et de l’accessibilité des techniques de génomique, transcriptomique et protéomique, la quantité de données disponible pour ces secteurs de recherche ne cesse d’augmenter. Malheureusement, la majorité de ces informations est encore stockée sous forme de documents textes non structurés et ce malgré la présence de certaines bases de données spécialisées. Toutefois, une technique existe pour interpréter automatiquement ces documents textes et en retirer les informations utiles : la “fouille de textes” (text mining). Bien que généralement utilisée dans d’autres secteurs que la biologie, par exemple pour extraire les mots revenant le plus souvent sur twitter, elle est toutefois capable d’isoler des informations bien plus ciblées telle que la relation entre deux gènes. Cette technique consiste à appliquer des analyses statistiques sur l’ensemble des mots issus d’un groupe de textes qui aura préalablement subi différents traitements tels que la séparation en phrases, la suppression de la ponctuation, etc … Le but était ici de développer un package R capable de rechercher automatiquement, sur base d’un ou plusieurs mot clé spécifiés par l’utilisateur (Chlamydomonas reinhardtii, …), les documents disponibles sur une base de données (“PubMed”, …), de les analyser et d’en extraire un réseau génétique d’interactions entre les différents gènes issus de ces documents. Au final, malgré l’identification de relations entre gènes d’espèces différentes à cause de sa capacité à isoler les gènes de plusieurs espèces, les prédictions générées par notre modèle peuvent être considérées comme satisfaisantes (score F1 de 68% pour l’identification des gènes dans le corpus CRAFT) compte tenu du fait qu’il n’utilise aucune ressource externe spécifique au type d’organisme analysé. La version finale de la librairie R “GeneMining” construite tout au long de ce mémoire est disponible sur le site http://www.biosys.ulg.ac.be/students/Lete/GeneMining_0.4.0.tar.gz. Enfin, les résultats intermédiaires obtenus au cours de ce mémoire ont fait l’objet de l’écriture d’un article pour la sixième conférence internationale de bioinformatique et sciences biomédicales à Singapour. L’article en question peut être consulté à l’adresse suivante : http://www.biosys.ulg.ac.be/students/Lete/ICBBS2017.pdf.

The management of wildlife populations and their habitats are interdisciplinary fields that encompass many scientific disciplines that also impact the lives of people. Therefore, these are truly applied sciences where human dimensions play an important role.This book highlights the importance of conducting rigorous studies to design and implement the effective management and restoration of wild populations and their habitats. A new paradigm in conservation is developing that goes beyond the boundaries of protected areas to achieve the goal of sustainable development. The 16 papers in this book, including reviews and a project report, cover a broad range of topics, exploring a diversity of subjects that are representative of current practices and novel applications.We would like to thank both the MDPI publishers and editorial staff for their support and help during the process of editing this book, in addition to the authors for their contributions.

This collection of 25 research papers comprised of 22 original articles and 3 reviews is brought together from international leaders in bioinformatics and biostatistics. The collection highlights recent computational advances that improve the ability to analyze highly complex data sets to identify factors critical to cancer biology. Novel deep learning algorithms represent an emerging and highly valuable approach for collecting, characterizing and predicting clinical outcomes data. The collection highlights several of these approaches that are likely to become the foundation of research and clinical practice in the future. In fact, many of these technologies reveal new insights about basic cancer mechanisms by integrating data sets and structures that were previously immiscible.
