WikiGap: Promoting Epistemic Equity by Surfacing Knowledge Gaps Between English Wikipedia and other Language Editions
This work addresses epistemic inequity for Wikipedia readers by making complementary knowledge from non-English editions more accessible, though it is incremental as it builds on existing multilingual methods and focuses on specific languages.
The paper tackled the problem of English Wikipedia dominating global knowledge access, marginalizing complementary facts from other language editions, by developing WikiGap, a system that surfaces complementary information from French, Russian, and Chinese Wikipedia within the English interface. In a study with 21 participants, WikiGap significantly improved fact-finding accuracy, reduced task time, and received a 32-point higher usability score compared to the existing system.
With more than 11 times as many pageviews as the next largest edition, English Wikipedia dominates global knowledge access relative to other language editions. Readers are prone to assuming English Wikipedia as a superset of all language editions, leading many to prefer it even when their primary language is not English. Other language editions, however, comprise complementary facts rooted in their respective cultures and media environments, which are marginalized in English Wikipedia. While Wikipedia's user interface enables switching between language editions through its Interlanguage Link (ILL) system, it does not reveal to readers that other language editions contain valuable, complementary information. We present WikiGap, a system that surfaces complementary facts sourced from other Wikipedias within the English Wikipedia interface. Specifically, by combining a recent multilingual information-gap discovery method with a user-centered design, WikiGap enables access to complementary information from French, Russian, and Chinese Wikipedia. In a mixed-methods study (n=21), WikiGap significantly improved fact-finding accuracy, reduced task time, and received a 32-point higher usability score relative to Wikipedia's current ILL-based navigation system. Participants reported increased awareness of the availability of complementary information in non-English editions and reconsidered the completeness of English Wikipedia. WikiGap thus paves the way for improved epistemic equity across language editions.
