We show how topic models are useful for interpreting and understanding MeSH, the Medical Subject Headings applied to articles in MEDLINE. We show how our resampled author model captures some of the advantages of both the topic model and the author-topic model. We demonstrate how the topic modeling approach can provide an alternative and complementary view of the relationship between MeSH headin...

Automatically assigning MeSH (Medical Subject Headings) to articles is an active research topic. Recent work demonstrated the feasibility of improving the existing automated Medical Text Indexer (MTI) system, developed at the National Library of Medicine (NLM). Encouraged by this work, we propose a novel data-driven approach that uses semantic distances in the MeSH ontology for automated MeSH a...

OBJECTIVES Efficient identification of subject experts or expert communities is vital for the growth of any organization. Most of the available expert finding systems are based on self-nomination, which can be biased, and are unable to rank experts. Thus, the objective of this work was to develop a robust and unbiased expert finding system which can quantitatively measure expertise. METHODS M...

These key words are based on the subject headings from the British Nursing Index. This article has been subject to double-blind review. The number of people with dementia is increasing alongside the social trend of a greater proportion of the population living on their own. But there appear to be few studies that focus on the theme of people with dementia living alone. The related area of risk ...

In this work, we raise the hypothesis that the density fluctuations field which originates the growth of large scale structures is a combination of two or more distributions, instead of assuming the widely accepted idea that the observed distribution of matter stems from a single Gaussian field produced in the very early universe. By applying the statistical analysis of finite mixture distribut...

Ontologies such as the Medical Subject Headings (MeSH) and the Gene Ontology (GO) play a major role in biology and medicine since they facilitate data integration and the consistent exchange of information between different entities. They can also be used to index and annotate data and literature, thus enabling efficient search and analysis. Unfortunately, maintaining the ontologies manually is...
