An evaluation of statistical approaches to MEDLINE indexing

Y Yang
1996 Proceedings : a conference of the American Medical Informatics Association. AMIA Fall Symposium  
This paper applies two statistical learning algorithms, the Linear Least Squares Fit (LLSF) mapping and a Nearest Neighbor classifier named ExpNet, to a large collection of MEDLINE documents.  ...  Whether or not high accuracy classification methods can be scaled to large applications is crucial for the ultimate usefulness of such methods in text categorization.  ...  In the MEDLINE database, for example, articles are indexed using Medical Subject Headings (MeSH) for the purposes of retrieval.  ...

The dimensions of indexing

W John Wilbur, Won Kim
2003 AMIA Annual Symposium Proceedings  
Indexing of documents is an important strategy intended to make the literature more readily available to the user.  ...  Here we describe several dimensions of indexing that are important if indexing is to be optimal. These dimensions are coverage, predictability, and transparency.  ...  Clearly the indexing vocabulary forms the basis for a language in which queries must be expressed and documents represented.  ...
