تحلیل ساختار واژگان و مفاهیم مقالات علم اطلاعات و دانش‌شناسی بر اساس تحلیل شبکۀ اجتماعی در پایگاه وبگاه علم در دو دورۀ قبل و بعد از پیدایش وب (1993-1997 و 2009-2013)

Purpose: This study aimed at the identification and analyzes of “Knowledge and Information Science (KIS)” scientific articles structure using co-word analysis in the “Web of Science (WoS)” database (1993-1997 & 2009-2013). By co-word analysis of the KIS articles, subjects and concepts of KIS were identified. Methodology: This study has based on descriptive and functional approach and on co-word analysis, using social network analysis techniques.

Findings: Co-word analysis showed that before the severe expansion of the Web services (1993-1997), the words “Library” and “Information” had good centrality, but in the recent period (2009-2013) the words "web", "information", "research", "citation analysis", "knowledge", "Library", "journals", and "technology" had high level of centrality in scientific documents. Originality/Value: The results of study have emphasized the importance of paying more attention to new areas of studies including knowledge organization, study of science and technology, web-based resources, Internet and information technology, and technical development of libraries. The mentioned areas have direct impact on teaching, research and service provision of libraries. By the coping with new trends, the educational policy-makers and planners of KIS can develop the new areas of studies in education of the required training topics and create the new trends in academic research.
