New knowledge emerges from pivotal articles that are central or bridge domains in Wikipedia. This study reveals how network structure drives knowledge growth in psychology and education.
Area of Science:
- Network Science
- Information Science
- Knowledge Management
Background:
- Understanding knowledge evolution is crucial for knowledge management.
- Wikipedia's structure offers a dynamic model for knowledge development.
- Previous studies often lack longitudinal network analysis.
Purpose of the Study:
- To investigate the structural development of Wikipedia's knowledge base.
- To explain the emergence of new knowledge using network analysis.
- To identify pivotal articles influencing future knowledge growth.
Main Methods:
- Longitudinal network analysis of Wikipedia articles (psychology and education domains).
- Analysis of article interlinkages across seven yearly snapshots (2006-2012).
- Application of multilevel modeling, eigenvector centrality, and betweenness measures.
Main Results:
- Pivotal articles, both domain-central and cross-domain, significantly predict new knowledge creation.
- The topological position of articles influences their role in knowledge evolution.
- Network structure dynamics are intrinsically linked to knowledge dynamics.
Conclusions:
- The structural position of articles within a knowledge network is a key determinant of future knowledge emergence.
- Identifying and understanding pivotal articles can help predict and foster knowledge growth.
- This approach provides insights into the dynamics of large-scale, evolving knowledge bases.
