In the realm of Artificial Intelligence, Large Language Models (LLMs) have recently emerged as a new technology, rapidly gaining prominence across various domains due to their impressive capabilities. This paper investigates key concepts, potentials and obstacles associated with integrating LLMs into the product development process. The initial focus lies on clarifying the underlying mechanisms and capabilities of LLMs to provide a clear and practical understanding. Building upon this foundation, the exploration shifts to the potential applications of LLMs in product development. An assessment matrix evaluates the capabilities of LLMs with regards to engineering challenges, highlighting how these models could potentially improve key aspects of the development process. Additionally, the obstacles associated with implementation in a product development context are addressed.

Machine learning of distributed word representations with neural embeddings is a state-of-the-art approach to modelling semantic relationships hidden in natural language. The thesis “Clustering of Distributed Word Representations and its Applicability for Enterprise Search” covers different aspects of how such a model can be applied to knowledge management in enterprises. A review of distributed word representations and related language modelling techniques, combined with an overview of applicable clustering algorithms, constitutes the basis for practical studies. The latter have two goals: firstly, they examine the quality of German embedding models trained with gensim and a selected choice of parameter configurations. Secondly, clusterings conducted on the resulting word representations are evaluated against the objective of retrieving immediate semantic relations for a given term. The application of the final results to company-wide knowledge management is subsequently outlined by the example of the platform intergator and conceptual extensions."
