Usage-based Calculation of Knowledge Maturing Indicators for Digital Resources in a Personal and Organizational Learning and Maturing Environment

Master's thesis Dieter Theiler 2012

Research in the field of ‘Knowledge Maturing’ focuses on improving knowledge construction processes within organizations. As guidance of knowledge workers plays an important role when it comes to developing knowledge, tools are sought to foster ‘Knowledge Maturing’-related activities. In this master thesis, ‘Knowledge Maturing Indicators’ get calculated upon traces of…

Visualisierung heterogener Datensätze in strukturierten Informationsressourcen

Master's thesis Belgin Mutlu 2012

The concept of the semantic web provides a pragmatic way for the structured informa- tion retrieval based on relationships within a content of the linked data. This retrieval is realized by applying the specific queries, i.e. SPARQL queries, on well-constructed data models. Besides the filter and navigation functions, a result…

Aspects of User Motivation in Social Tagging Systems

Dissertation Christian Körner 2012

Tagging describes the process of annotating resources with terms - so called "tags" - in order to enable better organization, retrieval and sharing of information. Today, a large number of diverse applications exist that allow users to annotate digital information from their libraries on the web. These systems are referred…

A User-centered Approach to Information Quality Assessment in Social Software Systems

Dissertation Nicolas Weber 2012

Over the past decade, the enormous increase in user generated content on the Web has provided an inexhaustible source of information, so much so that being able to find or locate a required piece of information has become more and more like finding a needle in a haystack. The problem…

Rule-based test data extraction for training machine learning algorithms

Bachelor's thesis Florian Salbrechter 2011

In this thesis we examine the automatic generation of training data in order to train a machine learning algorithm. We will use a rule-based approach to generate the training data which is build using the GATE Natural Language Processing framework. The machine learning algorithm is using a statistical model, the…

User Model Serivces for Adaptive Work-integrated Learning

Master's thesis Günter Beham 2011

A major challenge when designing software for work-integrated learning (WIL) is that the system provides real-time learning support adapted to a user’s situation and background knowledge (adaptive system). In order to adapt to the user’s situa- tion and characteristics, a user model is needed that is continuously updated to the…

Identifikation von relevanten Konzepten in einem Ontologie-basierten Kontext-Modell

Master's thesis Georg Kompacher 2011

Managing the massive amount of continously increasing personal information is becoming ever more difficult. Unobstrusive observation of the user in order to understanding the present user context can enable better support for the knowledge worker. The goal of this thesis is to identify entities of a user interaction context model…

Evaluating a User Model with Implicit Knowledge Diagnosis for an Adaptive Work-Integrated Learning System: A Field Study

Thesis (old curriculum) Christine Pabst 2010

A main challenge for adaptive learning systems, especially in a working context, is a continuously updated knowledge diagnosis. Implicit knowledge diagnosis is a possible solution to assess work-integrated knowledge through naturally occurring behavior actions from a worker. The present study focuses on the validity of an implicit knowledge diagnosis (Knowledge…

Suche und Klassifikation von informationstechnologischen Spezifikationen

Master's thesis Matthias Hilpold 2010

In our days the amount of digital data increases every day. A part of this data is available through the Internet for everyone and at any time. Different search engines support the user to find the desired information on the Internet. Even on an Intranet of a large company the…

Pragmatic Analysis of Tagging Motivation in Social Tagging Systems

Master's thesis Hans-Peter Grahsl 2010

Social tagging systems allow users to annotate different kinds of web-resources (URLs, photos, publications etc.) by means of a freely chosen and unbounded vocabulary of terms, so-called tags. While earlier research has been primarily focused on the analysis of the structure and the dynamics of social tagging systems, research has…

User Interaction Context - Studying and Enhancing Automatic User Task Detection on the ComputerDesktop via an Ontology-based User Interaction Context Model

Dissertation Andreas S. Rath 2010

User context detection has recently gained momentum, thanks to the interest shown by several established research areas, such as information retrieval, personal information management, technology enhanced learning as well as task and process management. In the information retrieval area user context is exploited for personalizing search, in personal information management…

Configurable User Profiling Service and Simulation's of User Behaivior in APOSDLE

Master's thesis Daniel Resanovic 2010

In a dynamical world of IT, adaptivity became one of the most important features. To enable adaptivity features of a system there has to be an appropriate infrastructure. Each component should be able to support and contribute to the adaptivity of such systems to a certain extent. How to design…

KnowFlow Report Engine – Ein graphen-basierter Ansatz zur automatischen Auswertung und Darstellung von Wissensprozessen einer Organisation

Thesis (old curriculum) Sebastian Dahlmann 2006

Management of knowledge gains more importance in many organisations. It is often referred to as one of the key success factors. However, knowledge processes in terms of generation, storage, transfer and application are still hard to identify. Most previous attempts failed to evaluate and represent knowledge processes, because they are…

Technology-Enhanced Workplace Learning: Modelling Competence and Performance for the Case of Requirements Engineering

Thesis (old curriculum) Barbara Kump 2006

From a psychological point of view, two models are required for the construction of an adaptive learning environment for informal, self-directed work-integrated learning (e.g., APOSDLE): the Knowledge Base, a model of the structured expert knowledge of a domain, and the S tudent Model, a model of the competencies of the…

Bewertung von Wissensrisiken. Vergleich von Modellen des Risikomanagements zur Bewertung von Wissensrisiken

Thesis (old curriculum) Maria Turek 2005

The Know-Center Graz is working on a framework for the integration of knowledge risks into existing risk management models and systems to enable particularly knowledge intensive companies to make their risk management more effective. The assessment of knowledge risks is a critical point in this context and its success depends…
