핵심 개념
Citizen science projects enable non-experts to contribute to scientific research, and this study examines the dynamics of collaborative knowledge production by analyzing the convergence of user-generated tags over time.
초록
This study investigates the collaborative tagging practices within the Gravity Spy citizen science project to understand how knowledge is created and shared among non-experts. The researchers leverage Association Rule Mining (ARM) to track the evolution of tag relationships over time and propose a novel algorithm to measure the convergence of tags towards specific values.
Key insights:
- 99.8% of the support metric time series (measuring tag pair relationships) converge, indicating a robust tendency for tag pairs to stabilize before proposal submission deadlines.
- The average convergence start point occurs approximately 2.3 weeks prior to proposal submission, suggesting early stabilization of tag pair relationships.
- 74% of tag pairs display stationarity (consistent statistical properties) before the proposal submission deadline, with an average of 100 weeks prior to the deadline.
- The study provides a detailed case study on the convergence of the {#helix} -> {#possiblenewglitch} tag pair, illustrating the distinction between stationarity and convergence.
The findings highlight the reliability and predictability of collaborative dynamics in citizen science projects, offering valuable guidance for effective research collaboration and proposal development. The proposed convergence detection algorithm provides a structured framework for analyzing the evolution of tag relationships, though it has some limitations in terms of robustness and scalability.

The average number of seed tags per proposal is 4.41, with a standard deviation of 6.31 and a median of 3.
The dataset contains 61,657 comments (42% of all comments) with a total of 78,803 tags, out of which 4,219 are unique.
Less than 12% of volunteers contribute comments, with 53% (1,749) of those volunteers included in the dataset.
Each proposal contains an average of 360 tags (with a standard deviation of 481 and a median of 80).
Each proposal involves an average of 167 volunteers (with a standard deviation of 313 and a median of 39).
The average "hit rate" (proportion of seed tags compared to the entire tag set) is 13%, with a median of 5%.
