Ranking themes on co-word networks: Exploring the relationships among different metrics
作者：
Highlights：
• Relationships among frequency-based and network-based metrics are examined on both empirical and simulated co-word networks.
• All seven metrics are strongly correlated, and according to the strength of correlations, the metrics can be categorized into three groups.
• Different disciplines do not influence the relationships among the metrics.
• Network topology properties influence the relationships among the metrics.
• A simulation method for co-word networks is proposed.
