Knowledge maps for e-learning. Jae Hwa Lee, Aviv Segev
Maps such as concept maps and knowledge maps are often used as learning materials. These maps havenodes and links, nodes as key concepts and links as relationships between key concepts. From a map, theuser can recognize the important concepts and the relationships between them. To build concept orknowledge maps, domain experts are needed. Therefore, since these experts are hard to obtain, the costof map creation is high. In this study, an attempt was made to automatically build a domain knowledgemap for e-learning using text mining techniques. From a set of documents about a specific topic,keywords are extracted using the TF/IDF algorithm. A domain knowledge map (K-map) is based onranking pairs of keywords according to the number of appearances in a sentence and the number ofwords in a sentence. The experiments analyzed the number of relations required to identify theimportant ideas in the text. In addition, the experiments compared K-map learning to document learningand found that K-map identifies the more important ideas
Does artificial neural network support connectivism’s assumptions?Alaa Al Dahdouh
Connectivism was presented as a learning theory for the digital age and connectivists claim that recent developments in Artificial Intelligence (AI) and, more specifically, Artificial Neural Network (ANN) support their assumptions of knowledge connectivity. Yet, very little has been done to investigate this brave allegation. Does the advancement in artificial neural network studies support connectivism’s assumptions? And if yes, to what extent? This paper addresses the aforementioned question by tackling the core concepts of ANN and matching them with connectivist's assumptions. The study employed the qualitative content analysis approach where the researcher started with purposely selected and relatively small content samples in connectivism and ANN literature. The results revealed that ANN partially supports connectivism’s assumptions but this does not mean that other learning theories such as behaviorism and constructivism are not supported as well. The findings enlighten our understanding of connectivism and where it may be applied.
What shapes what? Technologies and their relationship to learningMartin Oliver
Although there is a considerable body of work that explores educational uses of technology, and highly developed accounts of what learning is, surprisingly little research in education has asked what technology is, or what its relationship to learning consists of. When these matters are considered at all, they tend to be framed in technologically deterministic ways, with technology either 'causing' or at the least 'offering' and 'constraining' learning. In this talk, I will provide an overview of this way of framing technology and identify problems that follow from it. I will outline alternative positions that could be adopted, including Communities of Practice, the Social Construction of Technology and Actor-Network Theory, and discuss their points of connection to this debate. Using examples drawn from a JISC-funded project on digital literacies, I will draw out the implications of these positions for research.
Knowledge Management Cultures: A Comparison of Engineering and Cultural Scien...Ralf Klamma
This work in progress presents an approach to compare patterns of communication and knowledge organization in cultural and engineering science projects under the leading point of media use. The goal of the underlying project is to gain a better understanding on similarities and dierences in both areas and to develop more appropriate information system support for both areas. Central to the comparative analysis approach is a process knowledge repository which was successfully used in two case studies about real world information systems.
Learner Ontological Model for Intelligent Virtual Collaborative Learning Envi...ijceronline
An enacting approach to intelligent virtual collaborative learning model is explored through the lens of critical ontology. This ontological model enables to reuse of the domain knowledge and to make the knowledge explicitly available to the agent working as an Expert System, which uses the operational knowledge in collaborative learning environment. This ontological model used by the agent to identify the preliminary competency level of the user. This environment offers personalized education to each learner in accordance with his/her learning preferences, and learning capabilities. Here the factors considered to identify the learning capability taken are demographic profile, age, family profile, basic educational qualification and basic competency scale. The conception of heuristics is then used by the agent to determine the effectiveness of the learner by referring the different parameters of the learner available in the ontological model.To help getting over this, the paper describes the experience on using an ontological model for collaborative learning to relate and integrate the history of the learner by maintaining the history of learner in collaborative learning environment that will be used by the Multi-Objective Grey Situation Decision Making Theory to infer the understanding level of user and produces the conditional content to the user
GIVING THE LEARNERS CONTROL OF NAVIGATION: COGNITIVE GAINS AND LOSSESTamas Makany
Web based learning often involves exploration of the information space similar to the exploration of space in the real world. Initial paths taken in a novel physical or virtual environment will not only guide the discoveries of what the environment contains, but also formulate the underlying organising principles. The suggested route in a museum frequently presents artworks that are either chronological or conceptually tied together. Deviating from this –and taking a route of our own– might be either confusing or insightful. The structure of presenting the information and the control that the learners have in exploring it, plays a major role in determining mental representations and meaning. In the virtual world these possibilities and degrees of freedom in navigation are not constrained like the physical world, thus, can be colossal. The question that arises is what are the gains and losses of allowing the learners to freely control their explorations in an information space? To investigate this, we designed three web based learning environments that differed in their navigational structure, but not in their content. The first environment (Linear) was strictly sequential and did not allow any alternation from a defined sequence of the pages. With this Linear structure, the learners had almost no control over their navigation as they could only continue to the next page in the sequence or go back to the previous page. The second environment (Star) partially restricted control by connecting the webpages through a central homepage. The third environment (Interconnected) gave full navigational control to the participants, as every webpage was accessible from each of the other webpages. Detailed navigational behaviour was recorded and learning efficiency was measured. Participants answered the same questions immediately after learning and also after a period of two weeks in order to evaluate both short and long term learning outcomes. In this paper, we describe and interpret the results from the experiment with special focus on how control in web based learning enhances efficiency in one case; while hinders performance in others.

In particular, nature-inspired models of coordination emerged in the last decade as the most effective approaches to tackle the complexity of pervasive, intelligent, and self-* systems.
In the first part of the tutorial we introduce the basic notions of coordination and coordination model, and relate them to the notions of interaction and complexity. Then, the most relevant nature-inspired coordination (NIC) models are discussed, along with their relationship with the many facets of tuple-based models. In the third part we discuss the main open issues and explore the trends for future development of NIC. Finally, as a case study, we focus on MoK (Molecules of Knowledge), a NIC model for knowledge self-organisation, where data and information autonomously aggregate and spread toward knowledge prosumers.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

Abstract
In this article, the use of the self-organizing map
(SOM) is approached on the basis of current theories
of learning. Possibilities of computer and networked
platforms that aim at helping human learning are
also inspected. It is shown how the SOM can be
considered a model of constructive learning. The
area of constructive learning is outlined and two
cases of using the self-organizing map in computer
supported learning environments are presented.
Keywords
Self-Organizing Map, SOM, constructive learning,
cognitive models, memory models
Introduction
The phrase computer-aided learning earlier referred to
systems that helped the users in memorizing "facts".
Moreover, the cognitive models of learning have often
been based on a plain computer metaphor in which
learning is viewed as memorizing. In this article, we
focus on the constructivistic point of view considering
human problem-based learning: We also point out
how the Self-Organizing Map [1] appears to provide a
more realistic model of certain aspects of human
learning than many alternative models. After the
theoretical discussion we present how the selforganizing map could be used in computer supported
co-operative learning environments.
Self-organizing map
The self-organizing map (SOM) [1] is a widely used
artificial neural network model. In the SOM learning
process is unsupervised: no a priori classifications for
the input examples are needed. The learning process is
based on similarity comparisons in a continuous
space. The result is a system that associates similar
inputs close to each other in the two-dimensional grid
called the map. The input may be highly complex
multidimensional numerical data. Recently, the SOM
has also been used for the analysis and visualization of
symbolic and text data [2,3].
Constructive approach
During the past two decades, a constructive approach
to learning and knowledge has become dominant in
educational psychology. Learning is viewed as an
active, constructive process rather than a passive,
reproductive process (e.g., [4]). Students are
portrayed as intentional individuals who are primarily
responsible for their own learning.
In order to become experts, it is necessary for students
to construct qualitative models that are essential for a
deep structural understanding of their own field [5].
These conceptions are based on domain-specific
knowledge, but in addition to single facts, they consist
of concepts, propositions and theories [6]. The
structural organization of the domain-specific
knowledge base essentially differentiates between
novices and experts, and cognitive development
requires the reorganization of domain-specific
knowledge structures [7,8].
The novice/expert shift involves psychological
resistance and a gradual restructuring of the novice's
belief system [9]. Individuals construct certain
entrenched beliefs that are based on their everyday
experience and, depending on the domain, the
knowledge acquisition process requires a revision of
some of those beliefs and their replacement with a
new explanatory structure. This process may be called
conceptual change [10].
In current cognitive learning theory, three core
conceptions may be identified [11]. The first concept,
constructivity, is the idea that knowledge and
2. Proceedings of ICEUT’2000, IFIP, Beijing, August 21-25, 2000, pp. 339-343.
cognitive strategies are constructed by the learner, and
that learning involves qualitative restructuring and
modification of schemata, rather than just the
accumulation of new information in memory. The
second concept, active epistemology, is closely related
to constructivity, but refers specifically to beliefs
about the learner's role in the learning process. Mental
representation is the third core concept. In cognitive
learning theory, performance on problem-solving
tasks and students' explanations of such tasks are most
often accounted for by the nature of their mental
representations and also by their prior knowledge.
Moreover, representations are highly situational [12]
and knowledge is socially shared and constructed
[13,14].
Modeling constructive learning
The epistemological theories of knowledge have
traditionally been based on predicate logic and related
methodologies and frameworks. The basic assumption
is that the world consists of objects, events and
relationships. The language and the conceptual
structures and then supposed to reflect rather
straightforwardly this ontological structure. Learning
has been seen as a means to memorize the mapping
from the epistemological domain (to put it simply:
words) into the ontological domain (objects, events
and relationships). This view has been dominant at
least partly because of the consistent formalization of
the theory through the use of symbolic logic.
Moreover, the use of the von Neumann computer as
the model or metaphor of human learning and
memory has had similar effects and has strengthened
the idea of the memory as a storage of separate
compartments which are accessed processed
separately and which are used in storing and retrieving
information more or less as such. In the philosophical
discourse, there have been several opposing views
(e.g. [9]) but there have been little means to model or
formalize these ideas before connectionist models.
In cognitive science constructivists have questioned
the idea that the origin of knowledge is outside human
beings. Instead, they find that knowledge is a human
construction. The so-called “flat ontology” implies
that one’s view of reality emerges directly from
sensory data, without the need for any intervening
cognitive mechanism. However, the flat ontology
appears to have no empirical support [5].
Self-organizing map can also be considered as a
memory model. It is dynamic, associative and
consists of elements that can also be called adaptive
prototypes. Inputs are not stored as such but
comparison is made between the input and the
collection of prototypes. The closest prototype of the
input is adapted towards the input. The same
operation is also conducted for the neighboring
prototypes, which gives rise to the topographical order
on the map. Thus, the adaptation process in the selforganizing map algorithm is based on the principle
that what already exists in the system also influences
the learning result.
Considered superficially, one could claim that
modeling learning phenomena through the use of the
self-organizing map would be mentalistic. However,
it is possible to construct a model in which a number
of autonomous map-based agents interact in such a
way that they perform social construction of
knowledge and find intersubjective epistemological
agreements [15].
The self-organizing map can be used in visualization
of conceptually rich and complex phenomena.
Through constructive theory it becomes apparent that
there can be many and different interpretations and
points of view towards an area of discussion. This
kind of the subjectivity and intersubjectivity of
interpretation may be visualized by using selforganizing maps [16].
Maps for learning environments
In the following two cases of using the self-organizing
map in problem-based learning processes are
considered. An example of building a map of
conceptually rich area, namely that of cinematography, is presented. The process of inquiry learning
process supported by the use of the self-organizing
map is also considered.
Map of cinematographic concepts
The cultural and economical areas of cinematographic
expression and the production of films have been
conceptualized rather extensively. However, for a
student of those areas, a problem may be that the
relationships between the concepts may be difficult to
realize. A map of 199 cinematographic concepts from
the original idea into the final distributed film product
was produced [17]. Analyzing this kind of maps may
give relevant information about the filmmaking
process: how the concepts actually link with each
other.

is CSILE (Computer-supported Intentional Learning
Environments; [22,23]).
Figure 1. A map of cinematographic concepts based
on input by a first year student.
Figure 2. Elements of inquiry learning [19] and use of
CSCL and SOM in the process
A map based on first year film student’s answers was
also created (see Figure. 1). First, he was asked to
draw a mind-map about the concept "film". Second,
those 25 concepts were collected from the mind map.
The student was asked to provide values according the
method explained earlier in this article. The result
gives a picture how the student has conceptualized the
filmmaking process in his studies. A related webbased environment on filmmaking is accessible at the
site http://www.mlab.uiah.fi/elokuvantaju/
The recent Computer Supported Collaborative
Learning (CSCL) tools such as FLE (Future Learning
Environment, see http://www.mlab.uiah.fi/fle/) and
Knowledge Forum, support collaborative building of
knowledge and guided inquiry learning. With SOMs
the use of the CSCL tools could potentially be made
even more effective. In Figure 2, an inquiry learning
process using CSCL-tools and SOMs is presented.
Future Learning Environment
In problem-based inquiry learning process information
is treated as something that needs to be explained.
Instead of direct assimilation of the information
students should construct knowledge through solving
problems in communities [18,19]. By simulating
culture and practices of expert communities, such as
scientific research community or software/product
development teams, the students may engage
themselves in problem and explanation-driven
inquiry. To guide the student’s inquiry learning
process the collaboration in form of dialogue can be
carried out by using knowledge objects such as
problems, hypotheses, theories, explanations or
interpretations [19,20].
An example of an a practice in which one formulates a
theory of teaching-and-learning that can be shared
Teacher or supervisor may create the context by
presenting the SOM of the area under consideration.
The SOM of the context can be based on domain
experts’ interpretation of the conceptual relations in
the field. The SOM of the context may present wider
view to the study subject by presenting related
subjects and concepts close to the main area interest.
Discussion
All aspects of inquiry learning process, i.e. setting up
research problems, constructing one’s own working
theories, searching for new scientific information, can
be shared with fellow students by using CSCL shared
database. The knowledge-objects, for instance in form
of notes, can be produced as a dialogue so that each
note is commenting and linked to each another. The
metadata of each note contains information indicating
who is the author, what is the category of inquiry
defined by the author, and on which note it is referring
4. Proceedings of ICEUT’2000, IFIP, Beijing, August 21-25, 2000, pp. 339-343.
to. Different self-organizing maps (SOM) can be
generated based on this metadata and the written
information in the subject and body of the notes. The
SOMs may indicate which direction students should
continue so as to span the whole area under
investigation. The students and the tutors may also
compare the SOM generated by the experts and the
SOMs constructed by the students during the inquiry
learning process. Finally, the students’ SOM
constructed collaboratively can be included in the
experts’ SOM and this new SOM can then be used as
a new context of the students’ next course.
Future research with practical experiments will show
how effective the use of the SOMs will be from the
point of view of student learning. They provide
promising possibilities for visualizing and making the
conceptual change overt. What has already been
shown is that the SOM constitutes a useful framework
for modeling central concepts of constructive learning.
