Components of IoT

Contextual reasoning– How to improve application capacity to sense, understand, and reason

about complex and dynamic data and situation?

Knowledge representations and interaction techniques– How to augment cognitive reasoning with perceptual reasoning

through visual representations and interactions?

Data Representations and transformations– How to transform data into a representation that is appropriate to the

reasoning task and effectively patch the important content?

Production, presentation, and dissemination– How to convey analytical results in meaningful ways to various

audiences?
