Abstract
本研究では,van Deursen らの「デジタルスキル」を基礎に,従来の情報検索の専門的なスキルを組み込んだウェブ環境における情報検索スキルの現状を明らかにすることを目的とする質問紙調査を行った。2014 年8 月にオンライン調査を実施し,1,551 名から回答を得た。その結果,ウェブ環境で検索を行う人々は,(1)ブール演算子などの高度な情報検索技法は用いない,(2)ウェブ上の情報の形式は理解している,(3)検索語の選定に対する意識は高い,(4)一定の評価方針のもとに複数の検索結果を閲覧する,(5)インターネットから恩恵を受けていると感じている,ことが明らかになった。階層的クラスタリングにより回答者を8 クラスタに分割し,高い情報検索スキルを持つクラスタを特定した。この高能力者群は,比較的若く,男性が多く,学歴が高く,批判的思考能力と自己認識が高かった。高能力者群は全てのスキルの平均得点が最も高いが,検索技法に関するスキルのみ得点は大幅に低かった。 In this research, the information retrieval (IR) skills in web environment are newly defined as professional skills and knowledge for traditional information retrieval in conjunction with digital skills described by van Deursen. To assess the status of IR skills in Japan, an online questionnaire-based survey was conducted in August 2014. Ultimately, 1,551 participants responded. The results showed the following trends among the participants: (1) not using advanced search technique such as Boolean operator, (2) understanding the format of information on web, (3) carefully choosing search terms, (4) evaluating multiple search results based on certain evaluation criteria, and (5) feeling that they receive benefits from the Internet. Moreover, based on the hierarchical clustering analysis of their information retrieval skills, the participants were categorized into eight clusters. One of the clusters comprised the participants with highly performing IR skills. The characteristics of this cluster members included relatively younger generation, males, highly educated, high critical thinking ability, and high self-efficiency. Although this cluster members achieved the highest average scores on each IR skill, their scores on search technique skills were significantly less developed than those on other skills.
