著者キーワードを参考に考える看護分野の文献検索用語

摘要

文献検索では検索用語の選び方が重要である。看護師の検索用語選択には独特な傾向が存在し，独断的でrn不適切な用語や検索結果に期待のできない無効な用語の選択が行われている。図書館員はこうした事例をrn具体的に把握し，利用者への説明に活かしていく必要がある。そこで，看護分野における研究ではどのよrnうな言葉が検索用語として使われているのか，著者が付与するキーワードが検索のときに選ばれるキーrnウードでもあると理解してその特性を調査した。日本看護学会論文集の2003年から2005年の3年間におけrnる2,538論文に付与された合計9,392個,5,218通りの著者キーワードを索引誌「最新看護索引」の索引語とrnデータベース「医中誌Web」「JDream II」のシソーラス用語との照合を行った結果68%に当たる言葉が一致rnしなかった。この結果から問題点をまとめ，対処方法を考えた。%In the process of document search, the selection of search term is essential. Especially in the nursing field there is a characteristic tendency in the selection of search terms. The searchers are apt to select nontechnical terms but words locally used or phrases that are not appropriate for searching. As a librarian we are in the position to advice the users how to select effective search terms. So we studied how the existing searching system covers the terms and phrases that actually selected by the persons in the nursing field. We regard the author keywords, which are indicated in papers written by nurses as the search terms that are actually selected keywords when they search. As a study subject we select "Ninon Kangogakkai Ronbunshu" which is the proceedings of the Japan Nursing Association. The total of 9,392 author keywords is collected from the 2,538 articles published in the proceedings through 2003 to 2005. The 9,392 keywords were reduced to 5,218 unique words and phrases. We compared this 5,218 author keywords with the subject index of "Saishin Kango Sakuin (Japanese Nursing Index) ": A book-style index, and the thesauruses of two databases "Igaku-Chuo-Zassi (Japana Centra Revuo Medicina) " and "JDream II ". As a result, 68% of 5,218 words and phrases are not matched with these controlled search terms. Based on the result of this study, we summarized the points of issues and the recommendation for user instruction for nurses.
