متن کاملA One-Size-Fits-All Indexing Method Does Not Exist: Automatic Selection Based on Meta-Learning
We present a methodology that automatically selects indexing algorithms for each heading in Medical Subject Headings (MeSH), National Library of Medicine’s vocabulary for indexing MEDLINE. While manually comparing indexing methods is manageable with a limited number of MeSH headings, a large number of them make automation of this selection desirable. Results show that this process can be automa...
