This book focuses in detail on data science and data analysis and emphasizes the importance of data engineering and data management in the design of big data applications. The author uses patterns discovered in a collection of big data applications to provide design principles for hypothesis generation, integrating big data processing and management, machine learning and data mining techniques.The book proposes and explains innovative principles for interpreting hypotheses by integrating micro-explanations (those based on the explanation of analytical models and individual decisions within them) with macro-explanations (those based on applied processes and model generation). Practical case studies are used to demonstrate how hypothesis-generation and -interpretation technologies work. These are based on ¿social infrastructure¿ applications like in-bound tourism, disaster management, lunar and planetary exploration, and treatment of infectious diseases.The novel methods and technologies proposed in Hypothesis Generation and Interpretation are supported by the incorporation of historical perspectives on science and an emphasis on the origin and development of the ideas behind their design principles and patterns. Academic investigators and practitioners working on the further development and application of hypothesis generation and interpretation in big data computing, with backgrounds in data science and engineering, or the study of problem solving and scientific methods or who employ those ideas in fields like machine learning will find this book of considerable interest.

Zehn Jahre nach seiner Gründung im Jahr 2004 ist Facebook das größte soziale Netzwerk der Welt und einer der mächtigsten Global Player des Internet. Der Reiz dieses Netzwerks liegt auf der Hand: die geballte Kommunikation mit vielen, die Lust der Selbstdarstellung, die Zeugenschaft im Leben der anderen, die reichlichen, pflegeleichten Bekanntschaften, das Wiedersehen alter Freunde etc.. Auch die Negativseite ist hinlänglich bekannt: die Kapitalisierung des Privaten, Überwachung, Selbstdarstellungszwang, Zeitverschwendung. Es gibt etablierte Neologismen und umfangreiche Studien zu Facebook. Zugleich gibt es viele Klischees und Leerstellen in der Reflexion, was Facebook ist und wie es die Gesellschaft verändert.

I dati privi di struttura formale sono quelli che non hanno una forma o una struttura prestabilita e sono pieni di dati testuali. Tipici sistemi non strutturati sono le e-mail, i rapporti, le conversazioni telefoniche o di messaggistica, ecc. L'obiettivo principale di questo lavoro è estrarre le parole chiave da una conversazione utilizzando tecniche di intelligenza di sciame (SI). Le parole chiave vengono raggruppate in base alla loro classificazione e quindi suggerite all'utente. Nel lavoro proposto, utilizzando tecniche di ricerca incrociata, le parole chiave sono facili da cercare e forniscono alcune importanti parole chiave principali. Per la ricerca e il raggruppamento vengono utilizzati algoritmi separati. L'algoritmo Firefly viene utilizzato per il clustering per identificare parole chiave simili e correlate. Infine, i risultati mostrano che le tecniche SI hanno un effetto e una convergenza migliori rispetto alle diverse tecniche di estrazione delle parole chiave esistenti.

Los datos sin estructura formal son aquellos que no tienen una forma o estructura preestablecida y están llenos de datos textuales. Los sistemas sin estructura típicos incluyen correos electrónicos, informes, conversaciones telefónicas o de mensajería, etc. El objetivo principal de este trabajo es extraer las palabras clave de una conversación utilizando técnicas de Swarm Intelligence (SI). Las palabras clave se agrupan según su clasificación y luego se sugieren al usuario. En el trabajo propuesto, mediante el uso de técnicas de búsqueda entrecruzada, las palabras clave son fáciles de buscar y proporcionan algunas palabras clave importantes. Se utilizan algoritmos distintos para la búsqueda y la agrupación. El algoritmo Firefly se utiliza para la agrupación con el fin de identificar palabras clave relacionadas similares. Finalmente, los resultados muestran que las técnicas SI tienen un mejor efecto y rendimiento de convergencia en comparación con las diversas técnicas de extracción de palabras clave existentes.

Daten ohne formale Struktur sind solche, die keine vorher festgelegte Form oder Struktur haben und voller textueller Daten sind. Typische unstrukturierte Systeme sind E-Mails, Berichte, Telefon- oder Messaging-Gespräche usw. Das Hauptziel dieser Arbeit ist die Extraktion von Schlüsselwörtern aus einer Konversation mit Hilfe von Schwarmintelligenztechniken (SI). Die Schlüsselwörter werden nach ihrer Klassifizierung gruppiert und dann dem Benutzer vorgeschlagen. In der vorgeschlagenen Arbeit werden durch die Verwendung von Crisscross-Suchtechniken die Schlüsselwörter leicht zu finden sein und einige wichtige Top-Schlüsselwörter liefern. Für die Suche und das Clustering werden getrennte Algorithmen verwendet. Der Firefly-Algorithmus wird für das Clustering verwendet, um ähnliche verwandte Schlüsselwörter zu identifizieren. Schließlich zeigen die Ergebnisse, dass die SI-Techniken eine bessere Wirkung und Konvergenzleistung im Vergleich zu den bestehenden verschiedenen Schlüsselwort-Extraktionstechniken haben.

Die Einbindung von Bildungstechnologie in Hochschuleinrichtungen, insbesondere in Lehrerausbildungsstätten im Bundesstaat Mexiko, hat in den verschiedenen Lernumgebungen besondere Bedeutung erlangt. Der besondere Fall der Escuela Normal de Atlacomulco (ENA) bildet hier keine Ausnahme. Im Schuljahr 2016-2017 wurde mit einem Forschungsprojekt begonnen, um ein technologisches Werkzeug speziell für die Nutzung digitaler Plattformen zur Unterstützung der Lehrkräfte bei ihrer pädagogischen Arbeit zu entwickeln. Hervorzuheben ist auch die Bedeutung der Unterstützung des Lehrers für die Schüler während des Übergangs vom Paradigma des reinen Präsenzunterrichts zu einem anderen mit Unterstützung einer Bildungsplattform. Es ist wichtig, darauf hinzuweisen, dass im Einklang mit dem, was der Fernunterricht im Allgemeinen vorschlägt, das B-Learning- oder Blended-Education-Modell wieder aufgegriffen wird, bei dem die Lehrer und Schüler, die an dieser Forschung teilgenommen haben, der Meinung sind, dass eine bessere Organisation bei der Entwicklung eines Kurses und die räumliche und zeitliche Flexibilität bei der Durchführung von akademischen Aktivitäten die Merkmale sind, die die meisten Vorteile bieten.
