Knowledge Enhanced Language Models for Information Retrieval

Supervisor: Jeff Pan and Mirella Lapata

Pre-trained language models have been shown useful for improving the performance of information retrieval, in particular on query understanding. However, such models still suffer from lacking of knowledge and inference capabilities. This present project seeks to investigate how to enrich pre-trained language models with structured knowledge for information retrieval. Projects in this area could involve extending, combining or transforming language models with e.g. some common sense or domain specific schema and / or theory for tasks related to information retrieval, such as document ranking, and compositional reasoning for complex queries.
