ClusterTalk: Corpus Exploration Framework using Multi-Dimensional Exploratory Search

Exploratory search of large text corpora is essential in domains like biomedical research, where large amounts of research literature are continuously generated. This paper presents ClusterTalk (The demo video and source code are available at: https://github.com/achouhan93/ClusterTalk), a framework for corpus exploration using multi-dimensional exploratory search. Our system integrates document clustering with faceted search, allowing users to interactively refine their exploration and ask corpus and document-level queries. Compared to traditional one-dimensional search approaches like keyword search or clustering, this system improves the discoverability of information by encouraging a deeper interaction with the corpus. We demonstrate the functionality of the ClusterTalk framework based on four million PubMed abstracts for the four-year time frame.
