The popular KDnuggets news site for analytics, data mining and data science asked their visitors “What will replace “Big Data” as a hot buzzword?” and the most popular choice was “smart data”. I’m not sure what people meant by that, but can only imagine that it includes data that have explicit or implicit semantics and are annotated with metadata like temporal qualifications, provenance and certainty factors. These are all capabilities of current semantic web technologies, especially when coupled with machine learning for additional inference.
