Chapter 1: Semantics Acquisition and Usage
In informatics, every time a meaningful representation of ordinary human activities,
observations or tasks is undertaken, a final important step has to be fulfilled, i.e. the
interpretation of their semantics in a computationally efficient manner, so as for
them to be exploited within our digital world. Given the diversity of languages,
symbols, characters, meanings, etc. this effort is still characterized as an open
scientific area for anxious researchers. The following articles cover a selection of
topics that are central to the study of knowledge and semantics, tackling them from
both the acquisition and utilization perspective. Typically the acquisition process
follows different paths depending on the specific nature of meaning involved in
comparison to the way the meaning is utilized in order to provide meaningful
results. For each of these areas, the problems they pose for the semantics acquisition
and usage will be examined in general, whereas specific research findings derived
from fields like formal computational knowledge representation, embedded systems
analysis and synthesis, automatic surveillance systems analysis, as well as
exploitation of semantics and mobility within the education and job seeking
processes will be presented in detail.

Title: An Individual Differences Approach in Designing Ontologies for
Efficient Personalization
Authors: Nikos Tsianos, Panagiotis Germanakos, Marios Belk, Zacharias Lekkas,
George Samaras, and Costas Mourlas

In the search of resourceful personalization methodologies, this contribution
discusses the potential role of ontological knowledge structures towards the better
handling of their semantics. Its focus lies on possible ways of integrating cognitive
individual differences in the representation of users' cognitive characteristics,
leading to the development of an proposed ontological approach. By outlining the
field of cognitive abilities and by proposing a way for using some of these factors in
applied research fields, the interpretation of human behavior in today's digital
networking environment is advanced and further explored. Moreover, the
enrichment of ontologies with cognitive factors may lead to efficient personalization
and measurable benefits for users, thus resulting into very interesting scientific
outcomes.

Title: Formal Methods in High-Level and System Synthesis
Author: Michael F. Dossis

Given the nowadays constantly increasing amount of digital, networked computer
devices and their growing complexity, this article takes a step further into
researching deeper on their behavior understanding and elucidation. Its discusses
relations that exist between software and hardware aspects of portable computing
machines and embedded systems, focusing on high-level and system synthesis
aspects. It includes a survey and analysis of early and mature formal high-level and
system synthesis techniques, as well as the produced hardware implementations.
The recently renewed interest of industry and academia in the high-level synthesis
topic, motivated research on the underlying knowledge and semantics acquisition, so
as to achieve better quality of implementations and shorter specification-to-product
times with respect to everyday real-world applications.

Article 1.3
Title: Vision Based Semantic Analysis of Surveillance Videos
Authors: V. Fernandez Arguedas, Q. Zhang, K. Chandramouli,
and E. Izquierdo

Among others, a recent hot, cross-domain research topic with respect to the
meaningful blending of human activities and perception and computer-guided
interpretation is the automatic exploitation of data and knowledge from
surveillance systems. As a result, this contribution presents on the one hand an
extensive survey of different techniques that have been proposed for surveillance
systems, suitably categorized into respective categories, i.e. motion analysis,
visual feature extraction and indexing, whereas on the other hand, it describes a
practical implementation of an integrated surveillance framework for unsupervised
object indexing which closely resembles the generic architectures.

Article 1.4
Title: On the Use of Semantic Technologies to Support Education, Mobility
and Employability
Authors: Valentina Gatteschi, Fabrizio Lamberti, and Claudio Demartini

The final article of this book section deals with recent research activities in the
field of semantic technologies applied to education and job-seeking contexts. In
this framework, issues related to students' and workers' mobility, job-seeking and
hiring and the improvement of qualification offers are analyzed and compared, by
distinguishing different aspects, such as knowledge base creation, development of
integration strategies and definition of meaningful semantic inference rules. The
aim of this study is to understand the way technological advances, like the World
Wide Web or the Semantic Web, are actively exploited by their users. Towards
the production of new knowledge made available to other users.

Abstract. This article discusses the potential role of cognitive individual differ-
ences in the context of designing ontologies for personalization on users’ characte-
ristics. The theoretical framework of the proposed approach is derived from the
long tradition of psychometric testing, incorporating implications from the field of
differential and cognitive psychology. The current state of the identification and
systematization of mental abilities is depicted, with additional emphasis on the
constructs of working memory and cognitive style, on which a proposed ontology
is based upon. Also, a summary of previously conducted relevant empirical work
is presented, providing support to the notion of introducing personalization into
educational and commercial websites. To that end, the main argument of this work
is that the enrichment of ontologies with cognitive factors may lead to efficient
personalization and measurable benefits for users.
1 Introduction
The idea of developing adaptive and personalized systems has been mainly sup-
ported by arguments focusing on the drawbacks of the “one-size-fits-all” approach
(Brusilovsky and Maybury 2002) and essentially the complexity and vagueness of
the ever-expanding World Wide Web (De Bra et al. 2004). In parallel, researchers
and practitioners in the field of adaptive hypermedia underline the heterogeneity
of the user population, while it is often implied that “static”, non-personalized
systems fail to satisfy the needs and support the goals of different users
(Brusilovsky 2001). A certain degree of recognition towards this approach may be
deducted from the fact that web services such as Google, Bing, and Amazon are
nowadays offering personalized results and recommendations, by employing rule-
based and collaborative filtering techniques. Admittedly, though, these popular
services could not be classified as adaptive hypermedia, since they are lacking
many important features and functionalities; there is no user model, no varying
modes of presentation, and no navigational support, to name but a few of the
