Principles And History

Developing databases for emotion-oriented computing raises specific and complex issues at multiple levels, from the practicalities of recording to conceptual issues in psychology. Whether it is developing databases or using them, research in emotion-oriented computing needs to think about these issues rather than reflexively importing habits derived from other fields. Contemporary research identifies a number of principles that are relevant to making appropriate choices. They can be grouped under three broad headings - function; structure and scope; and relationship to psychological theory. These principles were not obvious when research in the area began. They have emerged gradually over a decade of relatively sustained work, and it is reviewed. Databases that have played a significant role in the process are listed, and selected case studies are examined in more depth. Lessons are drawn for future work at two levels, first at the level of an abstract overview and then at the level of practical issues that need to be addressed.
