Gem: Gaussian Mixture Model Embeddings for Numerical Feature Distributions
Hafiz Tayyab Rauf, Alex Bogatu, Norman W. Paton +1
Embeddings are now used to underpin a wide variety of data management tasks, including entity resolution, dataset search and semantic type detection. Such applications often involv…
Controlled LLM-based Reasoning for Clinical Trial Retrieval
Mael Jullien, Alex Bogatu, Harriet Unsworth +1
Matching patients to clinical trials demands a systematic and reasoned interpretation of documents which require significant expert-level background knowledge, over a complex set o…
An LLM-based Knowledge Synthesis and Scientific Reasoning Framework for Biomedical Discovery
Oskar Wysocki, Magdalena Wysocka, Danilo Carvalho +5
We present BioLunar, developed using the Lunar framework, as a tool for supporting biological analyses, with a particular emphasis on molecular-level evidence enrichment for biomar…
Active entailment encoding for explanation tree construction using parsimonious generation of hard negatives
Alex Bogatu, Zili Zhou, Dónal Landers +1
Entailment trees have been proposed to simulate the human reasoning process of explanation generation in the context of open--domain textual question answering. However, in practic…
Metareview-informed Explainable Cytokine Storm Detection during CAR-T cell Therapy
Alex Bogatu, Magdalena Wysocka, Oskar Wysocki +4
Cytokine release syndrome (CRS), also known as cytokine storm, is one of the most consequential adverse effects of chimeric antigen receptor therapies that have shown promising res…
Towards Schema Inference for Data Lakes
Nour Alhammad, Alex Bogatu, Norman W Paton
A data lake is a repository of data with potential for future analysis. However, both discovering what data is in a data lake and exploring related data sets can take significant e…
Dataset Discovery in Data Lakes
Alex Bogatu, Alvaro A. A. Fernandes, Norman W. Paton +1
Data analytics stands to benefit from the increasing availability of datasets that are held without their conceptual relationships being explicitly known. When collected, these dat…
Cost-effective Variational Active Entity Resolution
Alex Bogatu, Norman W. Paton, Mark Douthwaite +2
Accurately identifying different representations of the same real-world entity is an integral part of data cleaning and many methods have been proposed to accomplish it. The challe…
Data Context Informed Data Wrangling
Martin Koehler, Alex Bogatu, Cristina Civili +6
The process of preparing potentially large and complex data sets for further analysis or manual examination is often called data wrangling. In classical warehousing environments, t…
