This repository contains the metadata and data used in the dissertation “LLM-based Information Retrieval for B2B Matchmaking”. The research was developed using “in the wild” data from a B2B matchmaking company focused on matching buyers with sellers in an Information Technology (IT) e-marketplace (MatchIT; with which the research was developed in partnership). The dataset used in the research contains the profiles, offerings and demands of these buyers and sellers. Due to intellectual property considerations, however, this dataset could not be made available. Still, the source code of the matchmaking architecture that was developed is made available under a CC license (https://github.com/brunoRenzo6/LLM-based_IR_for_B2B_Matchmaking).
