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...

This paper presents a semantic model adapted for the indexing of electronic patient records (EHRs) as a support to the process of finding medical information. Given the specificity of such documents, the indexing is based on the sequence of Natural Language Processing steps: semantic annotation based on the use of the MeSH (Medical Subject Headings) thesaurus, concept disambiguation, extraction...

BACKGROUND To identify the: extent to which medical students in China experience burnout; factors contributing to this; potential solutions to reduce and prevent burnout in this group; and the extent to which the experiences of Chinese students reflect the international literature.

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...

This paper presents the development and experimental validation of a multizard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading but not acting simultaneously . A multicolumn pier-bent with concrete-filled steel tube CFST columns is the proposed concept, and the adequacy of this system is experim...

BACKGROUND Physicians are often encouraged to locate answers for their clinical queries via an evidence-based literature search approach. The methods used are often not clearly specified. Inappropriate search strategies, time constraint and contradictory information complicate evidence retrieval. AIMS Our study aimed to develop a search strategy to answer clinical queries among physicians in ...

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 ...
