Researchers found instant messaging (IM) user behavior exhibits a piecewise exponential and power-law distribution, revealing heterogeneous online activity across different time scales. This finding offers insights into communication patterns and user habits.
Area of Science:
- Complex Systems
- Human Dynamics
- Network Science
Background:
- Temporal characteristics of human dynamics are crucial for understanding various fields like communication and finance.
- Existing research identifies diverse non-Poisson distributions for inter-event times, including power-law and exponential.
- Emerging digital services may introduce novel distribution patterns.
Purpose of the Study:
- To investigate the inter-event time distributions for users of QQ and WeChat, two major instant messaging (IM) services in China.
- To identify and characterize novel distribution patterns arising from modern digital communication platforms.
- To explore the factors contributing to observed heterogeneity in user online behavior.
Main Methods:
- Analysis of time intervals between consecutive user visits to QQ and WeChat.
- Statistical modeling of inter-event time distributions using a small statistical unit (T=0.001s).
- Development of a combined exponential and interest model to capture behavioral heterogeneity.
Main Results:
- The inter-event time distribution for IM services follows a piecewise exponential and power-law pattern at a 0.001s scale.
- This distribution indicates heterogeneous user online behavior across different time scales.
- Inter-event time distribution exponents vary between cities, correlating with service popularity.
Conclusions:
- Instant messaging user behavior is characterized by heterogeneity, influenced by communication mechanisms and user habits.
- A combined exponential and interest model effectively characterizes this heterogeneity.
- Geographical variations in IM usage patterns are linked to service popularity, with implications for information diffusion and urban economic prediction.
