Towards a model of the digital university: A Generalized Net model for producing course timetables

In a series of research papers, the authors have studied some of the most important models of contemporary universities, such as: the research university, the entrepreneurial university and the digital university and construct their generalized net (GN) models. This paper is based on the case-studies of Sofia University, the Technical University of Munich and the University of Edinburgh. The main focus is to put the analysis of the processes of the functioning of a university which effectively integrates information and communication technologies (ICT) in all university activities. A concrete example based on the process of course administration at University of Edinburgh is considered. This university is in a process of developing an integrated information system covering most of the university activities. The opportunity of using GNs as a tool for modeling such processes is analyzed as well.

A model of the process of Big Data with generalized net

Theoretical generalized net (GN) model is presented. The aim is to follow the process of data lifecycle during a data analysis using Data Science. The presented model should be used during the process of huge amount of data, with various inner structure and near real time input speed.

A model of the process of big data with generalized net

Theoretical generalized net (GN) model is presented, which is describing interconnection between Big Datas components. The sequence of actions, referring to creation and functioning of Big Data warehouse, as well the information flow, is defined. The model is universal and independent of Big Datas problem area.

A Note on E-Learning Dynamic Assessment with Fuzzy Estimations

A model of an assessment module has been created, using intuitionisric fuzzy estimations, which render account on the knowledge of the trained objects. The final mark is determined on the basis of a set of evaluation units. An opportunity is offered no only for tracing the changes of the parameters of the trainer object, but there is also an opportunity of tracing the status of the already comprehended knowledge, as well as evaluating and changing the training themes and evaluation criteria

Personal Assistants in a Virtual Education Space

This chapter introduces personal assistants operating in a Virtual Education Space (VES). VES is built as an Internet-of-Things ecosystem consisting of autonomous intelligent components displaying a context-aware behavior. A personal assistant plays as an “entry point” to the space operating as a kind of intelligent user interface. The life cycle and the architecture of a generic personal assistant are presented in the chapter. Some suggestions for provision the assistant with learning capabilities are also given. A prototype implementation known as LISSA is discussed in more detail. Currently, a second version is developed known as IoT LISSA where the personal assistant will be able to account for the reality of the surrounding physical world in planning and executing its actions.

Generalized Net Model of Virtual Collaboration Space

As a discrete tool for universal description of adaptable, flexible, structured and reusable models of complex systems, generalized nets have been applied to modeling of various practical aspects of education and scientific research. Here, in continuation of previous research in this area, generalized nets (GN) have been used for development of a model of the process of personalization and adaptive usage of an intelligent virtual collaboration space. In the model, significant role is assigned to the Personal Assistant, which is a component in the context-dependent environment for delivery of e-services, e-learning content and collaboration. Assessments and patterns can be derived based on the GN model developed and the statistical data absorbed from real processes concerning the servicing of the virtual collaboration space.

Modeling of a learning management system

A theoretical generalized net model is proposed that describes the organization of e-learning in various subjects. Techniques for selection of an appropriate form of intervention are presented, as well as choice of alternative strategies during the training process. There are introduced criteria for assessment of the effectiveness of the learning management system with respect to the predefined training topics using intuitionistic fuzzy sets.

Ontology-Based Electronic Test Results Evaluation

The present paper examines an approach to automated test units evaluation, based on preliminarily created ontologies. Each test element is described by metadata, according to LOM standard. The learners’ results are evaluated by intelligent agents, using ontologies.

Generalized Net Model of E-learning System with Privacy Protection Module

The present paper introduces a generalized net model of e-learning system, which can satisfy some specific security requirements. The purpose is to analyze the major types of e-learning users and their roles into the distance learning process, as well as their interactions through the system. In addition, some security requirements to the e-learning system are considered and a security monitor is incorporated into the proposed model.
