The quality of entries in the world's largest open-access online encyclopedia depends on how authors collaborate, University of Arizona Professor Sudha Ram finds.
The patterns of collaboration between Wikipedia contributors have a direct effect on the data quality of an article, according to a new paper co-authored by a University of Arizona professor and graduate student.
Sudha Ram, a UA's Eller College of Management professor, co-authored the article with Jun Liu, a graduate student in the management information systems department (MIS). Their work in this area received a "Best Paper Award" at the Workshop on Information Technology and Systems held in conjunction with the International Conference on Information Systems, or ICIS.
"Most of the existing research on Wikipedia is at the aggregate level, looking at total number of edits for an article, for example, or how many unique contributors participated in its creation," said Ram, who is a McClelland Professor of MIS in the Eller College.
"What was missing was an explanation for why some articles are of high quality and others are not," she said. "We investigated the relationship between collaboration and data quality."
Wikipedia has an internal quality rating system for entries, with featured articles at the top, followed by A, B, and C-level entries. Ram and Liu randomly collected 400 articles at each quality level and applied a data provenance model they developed in an earlier paper.
"We used data mining techniques and identified various patterns of collaboration based on the provenance or, more specifically, who does what to Wikipedia articles," Ram says. "These collaboration patterns either help increase quality or are detrimental to data quality."
Ram and Liu identified seven specific roles that Wikipedia contributors play.
Starters, for example, create sentences but seldom engage in other actions. Content justifiers create sentences and justify them with resources and links. Copy editors contribute primarily though modifying existing sentences. Some users – the all-round contributors – perform many different functions.
"We then clustered the articles based on these roles and examined the collaboration patterns within each cluster to see what kind of quality resulted," Ram said. "We found that all-round contributors dominated the best-quality entries. In the entries with the lowest quality, starters and casual contributors dominated."
To generate the best-quality entries, she says, people in many different roles must collaborate. Ram and Liu suggest that the results of this study should spark the design of software tools that can help improve quality.
"A software tool could prompt contributors to justify their insertions by adding links," she said, "and down the line, other software tools could encourage specific role setting and collaboration patterns to improve overall quality."
The impetus behind the paper came from Ram's involvement in UA's $50 million iPlant Collaborative, which is funded by the National Science Foundation and aims to unite the international scientific community around solving plant biology's "grand challenge" questions. Ram's role as a faculty advisor is to develop a cyberinfrastructure to facilitate collaboration.
"We initially suggested wikis for this, but we faced a lot of resistance," she said. Scientists expressed concerns ranging from lack of experience using the wikis to lack of incentive.
"We wondered how we could make people collaborate," Ram said. "So we looked at the English version of Wikipedia. There are more than three million entries, and thousands of people contribute voluntarily on a daily basis."
The results of this research have helped guide recommendations to the iPlant collaborators.
"If we want scientists to be collaborative," Ram said, "we need to assign them to specific roles and motivate them to police themselves and justify their contributions."

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
