Abstract
Current research explores web analytics tools in the field of
electronic learning using agent-based and neural network
approaches. A hybrid agent-based model with built-in
artificial neural networks is proposed. The model aims to
support the computer simulation experiment assessment of
knowledge production and knowledge dissemination trends
among the agents of three types: authors, tutors and
students of on-line courses. In the research we study the
effectiveness of using the software to implement this model
as an example in one of the higher education institutions.
Conclusion
It is critically important to enhance the dialogue between
researchers and practitioners in order to guide the
development of new tools and techniques for analytics.
Agent-based modeling and artificial neural networks are
effective tools in developing web analytics (learning
analytics) in the production and dissemination of knowledge
by the e-learning participants.
Introduction
Approaches to the construction of hybrid ABM
Agent-Based Model (ABM) is a new tool for the extraction of knowledge in
various fields. Today, there are specialized publications in the internet
dealing with the ABM issues. For example, international online magazine
JASSS (Journal of Artificial Societies and Social Simulation) or Russian
Internet magazine “Artificial Societies”.
Fig. 1 Network architecture, the proposed master-making SNN
Agent-based models are constructed to create an artificial society in which
the following types of agents interact: A1 – authors of e-learning courses,
A2 – tutors involved in the learning process and A3 – students participating
in distant learning courses. We aim to investigate the effectiveness of the
AnyLogic package for designing a hybrid agent-based knowledge model,
which assesses the participants of e-learning courses on the basis of
neural networks, which belong to the new frontier of artificial intelligence.
The review of scientific papers in this area suggests that the results of
neural networks, which are based on a large number of observations,
reflect reality better than expert models, which survey a small number of
experts, or fuzzy logic systems, which use the rules laid down by several
people. With the purpose of designing artificial neural networks, we use the
data from the activity of web-centre users in one of Ukraine’s higher
education institutions. Fig. 1 shows examples of artificial neural networks
developed by means of STATISTICA Neural Networks for a hybrid agent-
based model. We should note that they have identical architecture which is
represented by multilayer perceptrons.
Fig. 2 The main window of computer experiments
The neural network allegedly accepts a decision of e-learning agents,
obtaining an input variable characterizing the growth in usefulness and
value of knowledge for the participants of an artificial society of this type.
The number of clicks, measured with allowances made for long term
threshold values, allows for assessing trends of knowledge production and
dissemination in the hybrid agent-based model by agents on the basis of
the activity results of each e-learning participant.
We may also observe the statistics of residual amount of knowledge and
number of meetings of each agent after the computer simulations.
Ideally, a hybrid agent-based model with integrated neural networks
allows describing data of layers, and providing analytics. We use the
multiple data sets and analytical tools in a single interface for the
visualization and data presentation. This helps in analysis of patterns of
production and knowledge dissemination of e-learning agents.
The Proposed Model in AnyLogic
Agent-based hybrid model was developed in the AnyLogic
environment. Among utility tools are variables, timers and statecharts
(flow charts or diagrams). Variables reflect the change in the
characteristics of e-learning course agents. Timers are set for a
specific time interval, after which the specified action will be performed.
Statecharts make possible to visually present agent's behaviour in
time, under the influence of events or conditions, which consists of
graphic states and transitions between them. Any complex behavioural
logic of the agents in the hybrid model designed in AnyLogic can be
expressed by a combination of utility tools, as well as embedded code
functions of three previously designed neural networks.
With the help of created model, we may see how much knowledge per
type of agent was produced in general and on average (see Fig. 2).
Here, the upper graph shows the dynamics of change in the number of
agents of each type. The X axis shows time of courses, and the axis Y
- number of agents. The middle graph represents the amount of
knowledge produced by each type of agents. Such a large number of
consumed knowledge among the students, represented in the graph, is
due to the fact that students rate in comparison with others is
remarkably higher: number of students - 140, number of tutors – 40,
DC authors – 20. The pie chart represents the average number of
produced and consumed knowledge for each type of agents.

Web Analytics in e-Learning: Agent-based and Neural Network Approaches Viktor Artemenko Lviv Academy of Commerce, St. Tugan-Baranovskogo 10, Lviv 79005, Ukraine, E-mail: victor.artemenko@gmail.com FD1 Abstract Current research explores web analytics tools in the field of electronic learning using agent-based and neural network approaches. A hybrid agent-based model with built-in artificial neural networks is proposed. The model aims to support the computer simulation experiment assessment of knowledge production and knowledge dissemination trends among the agents of three types: authors, tutors and students of on-line courses. In the research we study the effectiveness of using the software to implement this model as an example in one of the higher education institutions. Conclusion It is critically important to enhance the dialogue between researchers and practitioners in order to guide the development of new tools and techniques for analytics. Agent-based modeling and artificial neural networks are effective tools in developing web analytics (learning analytics) in the production and dissemination of knowledge by the e-learning participants. Introduction Approaches to the construction of hybrid ABM Agent-Based Model (ABM) is a new tool for the extraction of knowledge in various fields. Today, there are specialized publications in the internet dealing with the ABM issues. For example, international online magazine JASSS (Journal of Artificial Societies and Social Simulation) or Russian Internet magazine “Artificial Societies”. Fig. 1 Network architecture, the proposed master-making SNN Agent-based models are constructed to create an artificial society in which the following types of agents interact: A1 – authors of e-learning courses, A2 – tutors involved in the learning process and A3 – students participating in distant learning courses. We aim to investigate the effectiveness of the AnyLogic package for designing a hybrid agent-based knowledge model, which assesses the participants of e-learning courses on the basis of neural networks, which belong to the new frontier of artificial intelligence. The review of scientific papers in this area suggests that the results of neural networks, which are based on a large number of observations, reflect reality better than expert models, which survey a small number of experts, or fuzzy logic systems, which use the rules laid down by several people. With the purpose of designing artificial neural networks, we use the data from the activity of web-centre users in one of Ukraine’s higher education institutions. Fig. 1 shows examples of artificial neural networks developed by means of STATISTICA Neural Networks for a hybrid agent- based model. We should note that they have identical architecture which is represented by multilayer perceptrons. Fig. 2 The main window of computer experiments The neural network allegedly accepts a decision of e-learning agents, obtaining an input variable characterizing the growth in usefulness and value of knowledge for the participants of an artificial society of this type. The number of clicks, measured with allowances made for long term threshold values, allows for assessing trends of knowledge production and dissemination in the hybrid agent-based model by agents on the basis of the activity results of each e-learning participant. We may also observe the statistics of residual amount of knowledge and number of meetings of each agent after the computer simulations. Ideally, a hybrid agent-based model with integrated neural networks allows describing data of layers, and providing analytics. We use the multiple data sets and analytical tools in a single interface for the visualization and data presentation. This helps in analysis of patterns of production and knowledge dissemination of e-learning agents. The Proposed Model in AnyLogic Agent-based hybrid model was developed in the AnyLogic environment. Among utility tools are variables, timers and statecharts (flow charts or diagrams). Variables reflect the change in the characteristics of e-learning course agents. Timers are set for a specific time interval, after which the specified action will be performed. Statecharts make possible to visually present agent's behaviour in time, under the influence of events or conditions, which consists of graphic states and transitions between them. Any complex behavioural logic of the agents in the hybrid model designed in AnyLogic can be expressed by a combination of utility tools, as well as embedded code functions of three previously designed neural networks. With the help of created model, we may see how much knowledge per type of agent was produced in general and on average (see Fig. 2). Here, the upper graph shows the dynamics of change in the number of agents of each type. The X axis shows time of courses, and the axis Y - number of agents. The middle graph represents the amount of knowledge produced by each type of agents. Such a large number of consumed knowledge among the students, represented in the graph, is due to the fact that students rate in comparison with others is remarkably higher: number of students - 140, number of tutors – 40, DC authors – 20. The pie chart represents the average number of produced and consumed knowledge for each type of agents.
