Mining Big Data is the capability of finding
new useful information in complex massive datasets, that may be
continuously changing and may have varied data types. Big data is
helpful only when it is transformed into knowledge or useful
information. Data Intelligence is about transforming data into
information, information into knowledge, and knowledge into value. It
refers to the intelligent interaction with data in a rich, semantically
meaningful ways, where data is used to learn and to obtain knowledge.
However, extracting valuable information from this data by following the
classical Knowledge Discovery process reveals new previously unknown
challenges, due to Big Data properties. These challenges have received a
lot of attention in recent years, and still need more and more
contribution and research. A large number of publications have yielded a
plethora of proposed methods and algorithms. In this paper, we provide a
comprehensive literature review on Big Data current status. We present
the Data Intelligence framework in the context of Big Data from data
acquisition until insight extraction, we highlight its main issues, and
identify its progress in both technological and algorithmic
perspectives. We summarize and analyse relevant research papers in the field,
collected from different scientific databases. This investigation will
help researchers to understand the current status of Data Intelligence,
discover new research opportunities, and gain information about this
field.
Entropy
Based Personalized Learning Management System (Pelms) – An Approach
Towards Business and IT Education
(28-42)
Dinesh Kumar Saini
Development of personalized e-Learning
Management Systems (PeLMS) using advance modelling techniques is crucial
to achieve personalization and adaptation in content deliveries. This
paper delves on some important issues related to the integration of
PeLMS with Semantic Overlay Networks (SON). Developing a prototype for a
Business Statistics course delivery, a Semantic Web based PeLMS using
Topic Maps, Ontology, Classification rules, and ISA Algorithm has been
prescribed. Considering classification as one of the important aspects
in the content organisation in PeLMS, this study proposes a new
classifier, based upon the maximum entropy principle. It is argued that
the most similar items in a learning object repository space can be
classified together, on the statistical basis, to build a PeLMS. The ISA
algorithm has been proposed to enable this classification. The paper
also presents three key Learning Object Models for the organization of
contents and suggests how an optimal level of personalization that can
be ensured by maintaining the entropy within the system. Mechanisms such
as normalization and time complexity have also been suggested to ensure
personalized and optimal content delivery.

Increasing cyber-security presents an
ongoing challenge to security professionals. Research continuously
suggests that online users are a weak link in information security. This
research explores the relationship between cyber-security and cultural,
personality and demographic variables. This study was conducted in four
different countries and presents a multi-cultural view of
cyber-security. In particular, it looks at how behaviour, self-efficacy
and privacy attitude are affected by culture compared to other
psychological and demographics variables (such as gender and computer
expertise). It also examines what kind of data people tend to share
online and how culture affects these choices. This work supports the
idea of developing personality based UI design to increase users’
cyber-security. Its results show that certain personality traits affect
the user cyber-security related behaviour across different cultures,
which further reinforces their contribution compared to cultural
effects.
Recognizing and
Exploring Azulejos on Historic Buildings’, Facades by Combining Computer
Vision and Geolocation in Mobile Augmented Reality Applications
(57-74)

Mobile augmented reality (MAR)
applications assist users in navigating and exploring their actual
surroundings, displaying virtual contents that correspond to objects and
scenes in the real world. However, despite the growing popularity of
these applications, some experiences can be frustrating when users are
unable to correctly recognize Points of Interest (POI), objects, or
places they want to visit or obtain more information. The misleading
recognition can occur due to imprecise Global Positioning System (GPS)
data or a lack of QR codes for interaction. Hence, this article presents
a proposal that combines pattern recognition in images with geolocation
information to improve the accuracy of the identification of POIs. The
usage scenario is the identification of azulejos (tiles) on the facades
of historic buildings in the city of Belém of Pará, Brazil. This issue
is relevant based on similarities between azulejos and its huge amount
of different types, whose variety of designs and colors of geometric
forms can make the identification a hard task. The used methods to
extract the azulejos’ features were the co-occurrence matrix combined
with color percentage, and the global positioning data to increase the
accuracy of classification because similar azulejos can be
geographically far apart. Tests were conducted using six machine
learning algorithms (neural network, decision tree, k-nearest neighbors,
naive Bayes, random forest, and support vector machine) of different
paradigms. The first results show that the pattern recognition in images
combined with geolocation information is a promising approach for better
identification of the POIs in MAR applications.
SAHL: A
Touchscreen Mobile Launcher for Arab Elderly
(75-99)
Muna Al-Razgan and Hend S. Al-Khalifa
Mobile phones are becoming a great
necessity for elderly people; the features they provide supported by
rich functionality made them one of the indispensable gadgets used in
their daily life. However, as mobile phones get more advanced and their
interfaces become more complicated, new design recommendations and
guidelines need to be developed to serve the elderly needs. In this
project we distilled guidelines and design recommendations targeting
elderly users' needs. Then, we used these guidelines to implement a
prototype user interface that takes Arab elderly requirements into
considerations. We then evaluated the developed interface on a set of
Arab elderly people to determine its appropriateness for the target
audience.
