Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

The main objective of this thesis is to develop a Game With a Purpose that can be used as an alternative to a traditional tagging system for the Semantic Web, with a focus on improving data generation, user motivation, and overall system effectiveness. The key themes explored in this work include:

• Data generation for the Semantic Web
• Extreme Tagging Systems (ETS) as a tool for knowledge base development
• Gamification as a method for enhancing user engagement and motivation
• Evaluation of the effectiveness and fun factor of a Game With a Purpose compared to a traditional system
• Design and implementation of a multi-player game with a focus on collaborative and competitive elements

Zusammenfassung der Kapitel (Chapter Summaries)

• Chapter 1: Introduction - This chapter introduces the concept of the Semantic Web and highlights the chicken-and-egg problem associated with its development. It discusses the need for human labor in data generation and introduces the idea of Games With a Purpose as a potential solution to this problem. The chapter concludes by outlining the purpose of the thesis.
• Chapter 2: Background and Related Work - This chapter provides a comprehensive overview of the relevant background information, focusing on Collaborative Tagging Systems (CTS), Extreme Tagging Systems (ETS), Games With a Purpose (GWAPs), and a formal mathematical model for GWAPs. It also explores related work in the fields of semantics from user data and GWAPs.
• Chapter 3: Problem - This chapter describes two implementations of ETS, eXTS, and analyzes their shortcomings in terms of user participation, data quality, and the need for user guidance. It presents the results of an evaluation run with the initial eXTS implementation and identifies problems based on the gathered data.
• Chapter 4: Proposed Solution - This chapter introduces the proposed solution, a three-staged game designed to generate high-quality data for ontology development. It describes three minigames: the Racing Game, the Falling Words Game, and the Door Opening Game, and analyzes the impact of their order on data quality and user experience. It also discusses ways to enhance user motivation through various incentives.
• Chapter 5: Implementation - This chapter details the implementation of the Racing Game, focusing on general considerations like the choice of programming language, system architecture, and game development framework. It explains the use of the Game Gardens framework and provides code snippets to illustrate the implementation of key components like the distributed object, the game manager, and the game controller.
• Chapter 6: Mathematical Modelling - This chapter applies a formal mathematical framework to model the Racing Game, providing a precise description of the game's rules and mechanics. It describes the game problem domain, game rules, and game flow using the proposed framework.
• Chapter 7: Evaluation - This chapter presents the results of an evaluation run with the Racing Game and compares it to the traditional eXTS website. It uses objective measures like throughput, average lifetime play, and expected contribution to assess the productivity of both systems. It also analyzes subjective user perceptions using a questionnaire, focusing on factors like the fun factor and ease of use.
• Chapter 8: Summary and Conclusion - This chapter summarizes the key points of the thesis and concludes with proposals for future work. It suggests further developing and evaluating the proposed game, exploring ontology generation from the generated data, and analyzing the quality of the data itself.
