PubMedでは医学主題見出しMedical Subject Headings MeSHと呼ばれる語句が各文献にインデクサーによってインデクスされています。検索語句に対応するMeSHが同義語辞典シソーラスに含まれていれば、検索語句がその文献のタイトルやアブストラクトに含まれていなくても、そのMeSHでインデクスされている文献を探し出し、引き出すことで、同じ意味あるいは概念の語句が含まれている文献として引き出すことが可能になる仕組みです。その検索語句がMeSHであることを指示するには、語句に続けてあるいはスペースを入れて、[mh]と書きます。[mesh], [MeSH Terms]でも同じです。
MeSHはデータべース化されており、どのような用語があるか検索して調べることができます。また、MeSHは概念の広さによって、階層化されています。Decision Makingに関連する用語がMeSHではどのように扱われているか調べてみました。
