Plan Generation from Unstructured Documents Through Transformer-Based Extraction of Knowledge-Graphs

Maass, W.; Agnes, Cicy K.; and Harig, Amin

ECIS 2024

Planning for complex tasks is a key task for knowledge workers that is often time-consuming and depends on the manual extraction of knowledge from documents. In this research, we propose an end-to-end method, called PlanKG, that: (1) extracts knowledge graphs from full-text plan descriptions (FTPD); and (2) generates novel FTPD according to plan requirements and context information provided by users. From the knowledge graphs, activity sequences are obtained and projected into embedding spaces. We show that compressed activity sequences are sufficient for the search and generation of plan descriptions. The PlanKG method uses a pipeline consisting of decoder-only transformer models and encoder-only transformer models. To evaluate the PlanKG method, we conducted an experimental study for movie plot descriptions and compared our method with original FTPDs and FTPD summarizations. The results of this research has significant potential for enhancing efficiency and precision when searching and generating plans.

Public Transport in Rural Areas: Enabler or Disenabler of Mobility?

Wüttemberger, L., Janzen, S.

Proceedings of Wirtschaftsinformatik

Public transport can be a sustainable and efficient way to provide mobility. However, its use is declining while the number of car owners is escalating. Previous research overlooks the dual nature of public transport in rural areas, as it can be both a mobility enabler and disenabler, and the question of how digitalisation can influence this is also not sufficiently considered. This paper attempts to fill this gap through a comprehensive literature review, including the consideration of regional characteristics and system design. For this purpose, 21 papers were analysed and the challenges and opportunities for improving public transport in rural areas were identified. The findings underscore the need for holistic approaches integrating technological, organizational, and societal dimensions to maximize the benefits of rural public transport and address mobility challenges effectively.

Towards Sustainability of AI: A Systematic Review of Exisiting Life Cycle Assessment Approaches and Key Environmental Impact Parameters of Artificial Intelligence

Dokic, D., Groen, F., Maaß, W.

Hawaii International Conference on System Sciences

Most people are aware of the huge benefits that Artificial Intelligence (AI) brings to humanity in terms of sustainable applications (AI for sustainability). Yet, the fewest face the environmental impacts caused by an AI over its complete lifecycle (Sustainability of AI), e.g., the energy consumption, regardless how beneficial its outputs are. This paper presents a systematic literature review on the existing approaches for conducting a Life Cycle Assessment (LCA) on AI applications, alongside the key factors influencing their environmental impact. The study identifies critical environmental impact drivers of an AI over its life cycle, like the energy and resource consumption of hardware devices which provide the needed computing power. It underscores the importance of a holistic LCA approach considering operational and embodied energy use and the lifecycle impacts of data centers and other physical devices required for AI. The results provide critical insights for stakeholders looking to assess and mitigate the environmental impact of AI applications.
