Cognitive science is a science of intelligent systems. This chapter proposes that cognitive science can provide useful perspectives for research on technology-mediated human-information interaction (HII) when HII is cast as emergent behaviour of a coupled intelligent system. It starts with a review of a few foundational concepts related to cognitive computations and how they can be applied to understand the nature of HII. It discusses several important properties of a coupled cognitive system and their implication to designs of information systems. Finally, it covers how levels of abstraction have been useful for cognitive science, and how these levels can inform design of intelligent information systems that are more compatible with human cognitive computations.
The automated analysis of natural language data has become a central issue in the
design of intelligent information systems. Processing unconstrained natural language
data is still considered as an AI-hard task. However, various analysis techniques have
been proposed to address specific aspects of natural language. In particular, recent
interest has been focused on providing approximate analysis techniques, assuming
that when perfect analysis is not possible, partial results may be still very useful.
