The advancement of technology in today's world has led to the
progression of several professional fields. This includes the
classroom, as teachers have begun using new technological
strategies to increase student involvement and motivation. ICT
innovation including virtual reality and blended learning methods
has changed the scope of classroom environments across the globe;
however, significant research is lacking in this area. ICTs and
Innovation for Didactics of Social Sciences is a fundamental
reference focused on didactics of social sciences and ICTs
including issues related to innovation, resources, and strategies
for teachers that can link to the transformation of social sciences
teaching and learning as well as societal transformation. While
highlighting topics such as blended learning, augmented reality,
and virtual classrooms, this book is ideally designed for
researchers, administrators, educators, practitioners, and students
interested in understanding current relevant ICT resources and
innovative strategies for the didactic of social sciences and
didactic possibilities in relation to concrete conceptual contents,
resolution of problems, planning, decision making, development of
social skills, attention, and motivation promoting a necessary
technological literacy.
This unique text/reference reviews the key principles and
techniques in conceptual modelling which are of relevance to
specialists in the field of cultural heritage. Information
modelling tasks are a vital aspect of work and study in such
disciplines as archaeology, anthropology, history, and
architecture. Yet the concepts and methods behind information
modelling are rarely covered by the training in cultural
heritage-related fields. With the increasing popularity of the
digital humanities, and the rapidly growing need to manage large
and complex datasets, the importance of information modelling in
cultural heritage is greater than ever before. To address this
need, this book serves in the place of a course on software
engineering, assuming no previous knowledge of the field. Topics
and features: Presents a general philosophical introduction to
conceptual modelling Introduces the basics of conceptual modelling,
using the ConML language as an infrastructure Reviews advanced
modelling techniques relating to issues of vagueness, temporality
and subjectivity, in addition to such topics as metainformation and
feature redefinition Proposes an ontology for cultural heritage
supported by the Cultural Heritage Abstract Reference Model
(CHARM), to enable the easy construction of conceptual models
Describes various usage scenarios and applications of cultural
heritage modelling, offering practical tips on how to use different
techniques to solve real-world problems This interdisciplinary work
is an essential primer for tutors and students (at both
undergraduate and graduate level) in any area related to cultural
heritage, including archaeology, anthropology, art, history,
architecture, or literature. Cultural heritage managers,
researchers, and professionals will also find this to be a valuable
reference, as will anyone involved in database design, data
management, or the conceptualization of cultural heritage in
general. Dr. Cesar Gonzalez-Perez is a Staff Scientist at the
Institute of Heritage Sciences (Incipit), within the Spanish
National Research Council (CSIC), Santiago de Compostela, Spain.

Luciano Floridi presents an innovative approach to philosophy,
conceived as conceptual design. He explores how we make, transform,
refine, and improve the objects of our knowledge. His starting
point is that reality provides the data, to be understood as
constraining affordances, and we transform them into information,
like semantic engines. Such transformation or repurposing is not
equivalent to portraying, or picturing, or photographing, or
photocopying anything. It is more like cooking: the dish does not
represent the ingredients, it uses them to make something else out
of them, yet the reality of the dish and its properties hugely
depend on the reality and the properties of the ingredients. Models
are not representations understood as pictures, but interpretations
understood as data elaborations, of systems. Thus, Luciano Floridi
articulates and defends the thesis that knowledge is design and
philosophy is the ultimate form of conceptual design. Although
entirely independent of Floridi's previous books, The Philosophy of
Information (OUP 2011) and The Ethics of Information (OUP 2013),
The Logic of Information both complements the existing volumes and
presents new work on the foundations of the philosophy of
information.
This book is about the definition of the Shannon measure of
Information, and some derived quantities such as conditional
information and mutual information. Unlike many books, which refer
to the Shannon's Measure of information (SMI) as 'Entropy,' this
book makes a clear distinction between the SMI and Entropy.In the
last chapter, Entropy is derived as a special case of SMI.Ample
examples are provided which help the reader in understanding the
different concepts discussed in this book. As with previous books
by the author, this book aims at a clear and mystery-free
presentation of the central concept in Information theory - the
Shannon's Measure of Information.This book presents the fundamental
concepts of Information theory in a friendly-simple language and is
devoid of all kinds of fancy and pompous statements made by authors
of popular science books who write on this subject. It is unique in
its presentation of Shannon's measure of information, and the clear
distinction between this concept and the thermodynamic
entropy.Although some mathematical knowledge is required by the
reader, the emphasis is on the concepts and their meaning rather on
the mathematical details of the theory.

This book analyzes the methods, technologies, standards, and
languages to structure and describe data in their entirety. It
reveals common features, hidden assumptions, and ubiquitous
patterns among these methods and shows how data are actually
structured and described independently from particular trends and
technologies.
Examples of data structuring methods analyzed critically
include: Encodings (e.g. Unicode) Identifiers and Identifier
systems (e.g. ISBN) File systems Database Systems (record
databases, relational databases, NoSQL...) Data structuring
languages (JSON, XML, CSV, RDF...) markup languages (SGML, HTML,
TEI, Markdown...) Schema languages (BNF, XSD, RDFS, OWL, SQL...)
Conceptual modeling languages (ERM, ORM, UML, DSL...) Conceptual
diagrams
It is shown how particular method of data structuring and
description can best be categorized by their primary purpose. The
study further exposes five basic paradigms that deeply shape how
data is structured and described in practice. The third results is
a pattern language of data structuring. Patterns show problems and
solutions which occur over and over again in data. Each pattern is
described with its benefits, consequences, pitfalls, and relations
to other patterns.
The results can help to better understand data and its actual
forms, both for consumption and creation of data. Possible
applications include data analysis, data modeling, data
archaeology, and data literacy.
Daten werden uberall gesammelt. Jeder Kauf, ob online oder offline,
jede Autofahrt und jede Benutzung des Smartphones erzeugt Daten,
die gespeichert werden. So entstehen Datenberge, die in
atemberaubendem Tempo wachsen - fur 2020 geht man von 40 Billionen
Gigabytes aus. Aber was passiert dann mit diesen Daten? Wie werden
sie ausgewertet? Und wer macht das? Holger Aust nimmt Sie mit auf
einen unterhaltsamen Ausflug in die wunderbare Welt der Data
Science. Sein Buch richtet sich an alle, die schon immer wissen
wollten, wie Maschinen anhand von Daten lernen und ob sie dadurch
(kunstliche) Intelligenz erlangen. Sie erfahren naturlich auch, was
neuronale Netze und Deep Learning eigentlich mit all dem zu tun
haben. In leicht verstandlichem Stil erhalten Sie ausserdem
Einblicke in die Funktionsweise der wichtigsten Algorithmen und
lernen konkrete Beispiele, Herausforderungen und Risiken aus der
Praxis kennen: Sie erfahren etwa, wie Mobilfunkanbieter ihre Kunden
bei Laune halten, wie Erdbebenvorhersage funktioniert und warum
auch Computer zum Schubladendenken neigen.
