Reconsidering the measurement of tie strength in online social networks

Tie strength has long been used as one of popular network measures. However, the way of measuring tie strength has not been discussed much in the previous studies. Especially, there are few studies that focus on a theoretical understanding of tie strength measurements. In this study, we suggest a theoretical framework that clearly distinguishes different measures of tie strength. Then, by introducing the concept of theory of mind (ToM), we point out the current issue on the measurements of tie strength. Through an empirical verification, we propose a new way to measure tie strength that will improve the validity of future research
