Literature Search Basic II - future

上了 Literature Search Basic I - 2008 2，課後有同學問什麼是 focus 和 explode?

這不是四年級時「醫學資訊與電腦科技」上的內容嗎？大家可以看一下 OVID 的介紹：

• Terms in the tree go from more general (left) to more specific (right).
  
• Select the Explode box if you wish to retrieve results using the selected term and all of its more specific terms.
  
• Select the Focus box if you wish to limit your search to those documents in which your subject heading is considered the major point or focus of the article.
  

我們說 MeSH 的權威字是具階層結構的特性，所以若是選擇 Explode，結果將會包括指定的 MeSH 及他的子階層內所有的資料。想一想我課中舉的 myositis 及 inclusion body myositis 的例子吧。

如果 Search 還要上，那要教什麼呢？

後面的東西可能要幾年後才有機會講吧…可以再講兩個小時。只講 Search 還沒說 Appraisal 哈！
