A paraître dans / To appear in : ABSTRACT Many researchers in medical and life sciences commonly use the PubMed online search engine (http:// www.pubmed.gov) to access the MEDLINE bibliographic database. The researchers' strategies were investigated as a function of their knowledge of the content area. Sixteen life science researchers with no experience in neuroscience and 16 neuroscience resea...

In this paper, we explore the use of term relations in information retrieval for precision-focused biomedical literature search. A relation is defined as a pair of two terms which are semantically and syntactically related to each other. Unlike the traditional “bag-of-word” model for documents, our model represents a document by a set of sense-disambiguated terms and their binary relations. Sin...

In Part 1 of this series, we introduced you to the “ABCs” of matching, or “mapping,” clinical questions to resources, databases, and search strategies and identified some of the options likely to be useful to emergency physicians.1 Finding the best evidence is not always easy. The busy clinician faced with a computer terminal, Web connection, and a clinical question may find herself wishing ins...

In this paper we examined the relationship between semantic relatedness among medical concepts found in clinical reports and biomedical literature. Our objective is to determine whether relations between medical concepts identified from Medline abstracts may be used to inform us as to the nature of the association between medical concepts that appear to be closely related based on their distrib...

OBJECTIVE This study analyzed data from a study on the value of libraries to understand the specific role that the MEDLINE database plays in relation to other information resources that are available to health care providers and its role in positively impacting patient care. METHODS A previous study on the use of health information resources for patient care obtained 16,122 responses from hea...

With the rapid expansion and utilization of the Internet and Web technologies, there is an increasing number of on-line medical journals. On-line journals pose new challenges in the areas of automated document analysis and content extraction, database citation records creation, data mining, and other document related applications. New techniques are needed to capture, classify, analyze, extract...
