bioCADDIE

bioCADDIE is a data indexing project aggregating publicly accessible biomedical datasets into a single portal to facilitate their reuse and accelerate scientific discoveries. As indexed datasets grow, retrieving relevant datasets based on researchers' queries becomes increasingly challenging.

The authors propose an information retrieval (IR) system that utilizes advanced techniques such as state-of-the-art IR models, medical named entity extraction, query expansion with deep learning-based word embeddings, and a re-ranking strategy to address this issue.

The system leverages the unstructured text data associated with each dataset, including titles and descriptions.
