MeSH terms versus keywords
Do MeSH terms (or Emtree for that matter) work better than keyword or full text searching?
There is a fascinating discussion ongoing over at fxpal between librarians and information researchers regarding the use of MeSH terms in medical literature and if MeSH actually adds any value. (This discussion continues on to medical literature searching in general). Included in the discussion is a link to an old paper demonstrating that MeSH shows statistically insignficant value over full text search (paper here).
We all have our experiential views of MeSH, but the author’s conclusion is interesting – that there isn’t a solid body of evidence characterizing the effectiveness of such a thesaurus (or is there?)..
