Large Language Models for Knowledge Harvesting, Sharing, and Management
Job description

Knowledge is a vital asset for individuals, organizations, institutions, and society. Large Language Models (LLMs) have the potential to revolutionize how knowledge is generated, shared and managed by automating the extraction of relevant information from vast amounts of unstructured data, synthesizing it into coherent narratives, and injecting it in multimodal user interactions. Recent advances, such as Retrieval Augmented Generation (RAG), enable LLMs to parse through extensive documents, identify key points, and summarize content, rendering the information more accessible and comprehensible for users. Through dialectic techniques, LLMs can facilitate (tacit) knowledge extraction from expert users and instrument knowledge sharing with novice ones. LLMs can also be fine-tuned to categorize, tag, and retrieve information, responding to queries with relevant documents or even specific text passages. Using an intermediate layer, LLMs can translate natural language querries into a compatible format for popular databases (e.g., MySQL, Neo4j) thus expanding existing knowledge bases. By enabling more efficient search and discovery processes, LLMs help maintain an organized and dynamic knowledge base, supporting continuous learning and decision-making within organizations and beyond. This PhD research will also investigate the technical and algorithmic challenges involved in information retrieval techniques beyond RAG. This research will seek to answer the following Research Questions (RQs):    


  • What methodologies can be developed to ensure LLMs effectively summarize complex knowledge without losing critical information?
  • How can LLM-generated natural language explanations enhance knowledge sharing among individuals with varying levels of expertise?
  • How can continuous learning be integrated into LLM-powered systems to adapt to evolving data and knowledge without extensive retraining?
  • What are the potential pitfalls when utilizing LLMs to manage knowledge (e.g., biases, hallucinations), and how can they be mitigated to ensure fair and unbiased information dissemination?


The successful candidate will design, develop, and evaluate LLM-powered prototypes with the aim to discover, harvest, share and manage knowledge in a context-agnostic fashion. Novel LLM-powered prototypes will be deployed in real-life contexts that encompass creativity and design, healthcare, manufacturing, energy and others to showcase (societal) impact. The successful candidate will be based at TU Delft and will have the chance to work with partners across TU Delft (e.g., Faculty of EEMCS & 3ME), beyond TU Delft (e.g., Erasmus MC, Leiden University), as well as with international and industrial project partners (e.g., Ortec B.V.).
