Towards Large Language Models for Everyone: Instruction Following, Knowledge Retrieval and Multilingualism
… user requests. Secondly, LLMs suffer from knowledge cut-off and tend to hallucinate about long-tail facts. Lastly, popular LLMs are trained on almost exclusively English text, making it difficult for non-English speakers to adopt them. This thesis presents methodologies addressing all three …

Can I borrow your expertise? Integrating transactive memory system, social network, and social resources theory
As information and knowledge are increasingly critical resources in organizations, a key question facing organizations today is ‘knowing who knows what’ rather than ‘knowing what.’ However, awareness of others’ expertise does not necessarily lead to the utilization of that knowledge. Integrating …
