Lehrstuhl Informatik 5 Thema: Chatbots as Professional Companions in Large-Scale Community Information Systems: Integrating Chatbots in Educational Ecosystems Abstract: Online communities are fundamental for knowledge sharing, collaboration, and professional development in our digital age. However, challenges like information overload and low engagement hinder their effectiveness. New members often struggle to find accurate information from multiple sources. Chatbots with natural language understanding and automation capabilities can solve these challenges. By providing personalized guidance, improving efficiency, and integrating with external knowledge bases, chatbots enhance the user experience in online communities. Unfortunately, community members often lack the necessary resources or expertise to create bots that optimize their practices. This dissertation follows a design science approach that empowers communities to create and maintain customized chatbots collaboratively. We introduce a model-driven Social Bot Framework that allows community members to participate in bot creation and evaluation. This framework incorporates process mining techniques and leverages Large Language Models (LLMs) to enhance bot performance. The dissertation also presents a catalog of success factors for bots, providing a multi-dimensional model for assessing chatbot effectiveness within communities of practice. Through a co-design process involving real-world use cases, we have produced, demonstrated, and evaluated chatbots as artifacts, showcasing their impact and usefulness. Our research explores the application of chatbots in Technology Enhanced Learning (TEL). We developed a series of mentoring bots that address various aspects of the educational process. These include systems for collaborative knowledge building, providing personalized feedback on writing tasks, and facilitating quiz-based learning. We also investigated the integration of gamification elements to enhance user engagement and motivation in educational contexts. Furthermore, we leveraged LLMs to provide more sophisticated, personalized learning support. The evaluations, conducted through user studies, surveys, and performance metrics, demonstrate the effectiveness and user acceptance of our developed chatbots. Our research promotes the democratization of bot-building, enabling communities to leverage chatbot potential. This represents a significant advancement in the self-governance and development of online communities in response to changing needs and opportunities. Ultimately, this work pushes the boundaries of current community practices, opening up new horizons where bots are professional companions supporting the success of online communities.
