Abstract
This paper discusses phenomena of interest of Cognitive Linguistics, connecting the perspective of Information Science and other linguistic approaches, and having categorization as a guide in the discussion. It addresses the concepts of semic componential analysis and dictionary and encyclopedic knowledge to then deal with Cognitive Linguistics theories such as family resemblances, Frame semantics, radial categories, prototypes theory, and finally fluid categorical barriers. The conclusions are that the categorization happens through complex processes that reflect experimental, imaginative and ecological aspects of the human mind, refuting the idea that the categories have clear and strict limits.
