An activity theoretic model for information quality change is a publication by Besiki Stvilia, Les Gasser.


[edit] Abstract

To manage information quality (IQ) effectively, one needs to know how IQ changes over time, what causes it to change, and whether the changes can be predicted. In this paper we analyze the structure of IQ change in Wikipedia, an open, collaborative general encyclopedia. We found several patterns in Wikipedia's IQ process trajectories and linked them to article types. Drawing on the results of our analysis, we develop a general model of IQ change that can be used for reasoning about IQ dynamics in many different settings, including traditional databases and information repositories.

[edit] Research questions

"In this paper we develop a general model of IQ change based on an analysis of IQ process data in Wikipedia. Some statistics on the IQ dynamics of Wikipedia articles are also presented."

Theories: "Activity theory allowed us to develop a conceptual model for reasoning systematically about the general context of IQ in Wikipedia — a hierarchy of goal–oriented activities, roles, and the integration points of different sociocultural aspects of the activity system. This activity theoretic model then guided us in data selection by suggesting specific processes which might involve explicit evaluation and decision making on an article’s quality." [edit item]

[edit] Conclusion

"In this study we analyzed time series data on the edit processes of FAs and FFAs. Although the time series data exhibited different trajectories for different articles, we observed a number of stable patterns in the trajectories. The patterns appeared to follow the life cycles of the underlying entities.

An analysis of FAR and FARC discussions on FFAs showed that IQ could be changed not only actively by editors, malicious agents, or IQA agents editing the article, but also passively by changes in the article’s underlying entity or the context of its evaluation and use. The IQ of the majority of FFAs had been re–evaluated as lower, and these FFAs lost their high–quality status after the community decided to increase IQ requirements.

We believe that this study of the patterns of IQ processes and the sources of IQ variance in Wikipedia can contribute to a better understanding of IQ dynamics, and that it has useful implications for optimizing IQ assurance in traditional databases. In particular, the activity theoretic model of IQ change and information type specific edit process patterns identified in this study can serve as a reusable knowledge resource for predicting IQ changes and guiding IQ maintenance actions and resource allocation. The model can also inform the design of software architecture and tools for automatic IQ assurance. Future work will include investigating the cost structure of IQ and linking it to IQ decision–making."

Statistical analysis; Content analysis; Time series

The research method used in this study consisted of a combination of (1) a conceptual modelling of Wikipedia information processes; (2) a descriptive statistical analysis and an analysis of time series data of article attribute data; and, (3) a content analysis of quality evaluation discussions."
