| dc.description.abstract (摘要) | 本研究運用布萊德福定律(Bradford`s Law)和布萊德福－齊夫定律(Bradford-Zipf`s、Law)，一方面分析資訊科學引用文獻(citing literature)與被引用文獻(cited literature)的文獻分散現象，並比較其差異性；另一方面利用LISA資料庫敘述語(descriptor)欄位量化分析引用文獻與被引用文獻的主題分布情況及變化。研究結果顯示：資訊科學文獻呈現報酬遞減分散且不符合布萊德福定律；引用文獻較被引用文獻分散；引用文獻與被引用文獻共同的核心期刊有五種；二者最常見的研究主題計有專業教育、書目計量學、資訊工作、引用文獻分析、搜尋等。 | - |
| dc.description.abstract (摘要) | Employing the bibliometric laws, this study investigated literature scattering and subject change between the citing and cited literature on information science. This study first used the Bradford`s Law and the Bradford-Zipf`s Law to identify the core journals of information science. Then, using the descriptors in LISA to quantitatively analyze the key concepts for core journals of citing and cited literature. A total of 1,492 citing literature, published from 1985 to 2005, were searched on Web of Science database. Moreover, 8,813 cited literature was obtained from citing literature. The results of this study reveal that the scattering of citing and cited literature on information science shows diminishing returns; both scatterings do not fit with the Bradford`s Law and Bradford-Zipf`s Law; the citing literature scatters more than the cited literature does; five core of the core journals on information science are identified; the subjects in common of citing and cited literature are professional education, bibliometrics, information work, citation analysis, searching, etc | - |
