Citation Analysis的假設前提 • Citation of a document implies use of that document by the citing author.→有些資料曾被閱讀, 但未被引用 • Citation of a document (author, journal, etc.) reflects the merit (quality, significance, impact) of that document (author, journal, etc.). →有時是負面引用 • Citations are made to the best possible works. →有些 作品不著名, 或是導論入門型的作品並未被引用 • A cited document is related in content to the citing document; if two documents bibliographically coupled, they are related I content; and if two documents are co- cited, they are related in content. →並不一定 • All citations are equal. →並不一定 Source from: Smith, 1981

  79. 79. Altmetrics的價值 • Author – Readership – Supplements to IF of journal • Repositories – Potential depositors and their open contents – Another usage statistics – Help in collection development and planning • Administrator – Showcase of university scholarship to both internal and external stakeholders – Better understand how a particular researcher’s work has been received by scholarly and lay communities Source: Konkiel & Scherer, 2013
  80. 80. ALMs • PLoS and SPARC • ALMs: Article Level Metrics – 以個別文獻為主要對象 – 聚合不同的來源資料,尤其是社會網路化與即時性 – 能見/曝光度:學術與社會化 – 與Altmetrics不同,以評估個別的文獻、期刊、學 者,及其他 – ALMs不會被某一公司或企業獨立擁有或把持 – 與現有的metrics互補 Source: Tananbaum, 2013

  85. 85. Evolutional metrics and findings • 3 Stages and Types – Citation analysis – WoS & JCR – Webometrics (Link Analysis) – Google Scholar’s Metrics – Web 2.0 analysis – Altmetrics & ALMs • Scope and Granularity – Journal - Article - Data sets - PPT- Figure & Table – Country - Institute - Group - Individual • Data Source and Quality • Source – Calculation & Algorithm→Counts
  86. 86. 建議 • 留意各項需求的改變及其發展 • 資料的來源及其正確性與限制 • 數據的差異性及其標準化:不同學科領域 • 資料詮釋與應用的觀點:脈絡(context) • 不同觀點及其多元化 • 計算方式:factor vs. count • 不同識別碼及其代表資訊物件的重複問題:DOI及 其他(如:ORCID) • 標準:資料的來源及其提供的項目與定義 • Digital Preservation及數位資訊消失的問題 • 其他:不同的個人與電腦軟體程式的潛在影響
  87. 87. Citation Analysis假設前提 應用在Altmetrics的情境 • Citation of a document implies use of that document by the citing author.→有些資料曾被閱讀, 但未被引用? • Citation of a document (author, journal, etc.) reflects the merit (quality, significance, impact) of that document (author, journal, etc.). →有時是負面引用? • Citations are made to the best possible works. →有些 作品不著名, 並未被引用? • A cited document is related in content to the citing document; if two documents bibliographically coupled, they are related I content; and if two documents are co- cited, they are related in content. →並不一定? • All citations are equal. →並不一定?
