Subjective Information Processing: Its Foundation and Applications

Subjectivity is inherent characteristics of information processing by/in humans, but almost no researcher has tackled this issue as main theme. Thus, this paper aims to give the readers a framework of subjective information processing (SIP) at first. Moreover, treatment of subjectivity in several natural sci- ences and relationships of SIP with related fields of engineering are described. Another aim is to show potential of SIP through an example; a model for communicating subjective degree with adverbs of degree.
