WikiAnalytics
Andrey Balmin, Emiran Curtmola · 2010
Wikipedia infoboxes is an example of a seemingly structured, yet extraordinarily heterogenous dataset, where any given record has only a tiny fraction of all possible fields. Such data cannot be queried using traditional means without a massive a priori integration effort, since even for a simple request the result values span many record types and fields. On the other hand, the solutions based on keyword search are too imprecise to capture user's intent.
