Process Characterization Methods Based On "mental Operation" Knowledge Work

Human brainwork creates knowledge economics and promotes knowledge management, so the efficiency of brainwork naturally becomes the main content of knowledge management as well as the focus and hotspot of modern management research. Knowledge work/task sustained by brain is human cognitive process. At present, numerous research in management field focus on supportive aspects of knowledge task, but lack the process itself. From the view of process control, the main problem of enhancing knowledge task efficiency is the description and representation of knowledge task process, which is the purpose of this research.The representation of knowledge task process is not only the management problem, but also the problem of cognitive science. This research emphasizes particularly on discussing the general method of describing knowledge task process and the mind operations (MO) used in individual cognitive process (information processing process).Based on literature overviews, operational definition of knowledge task and knowledge task process analysis, this research presented the mind operation set model of knowledge task process. According to theoretical analysis and several times pre-tests, it formed Knowledge Task Process Mind Operation Modes Questionnaire. After sample investigation, it carried through the confirmatory factor analysis of the mind operation set model based on sample data and statistic test analysis on sample data. Besides, on the basis of mind operation set model of knowledge task process, it used BP (Back Propagation) neural networks to construct the recognition model of knowledge task type (choose 92 representative questionnaires), and this embodied the deduction analysis of using mind operations to represent knowledge task process. The results of this research were as below:(1) It could use mind operation set to describe and represent knowledge task process. The basic mind operations include metacognition, distinguishing, memory, transforming, imaging, characters extracting, character integrating, reasoning and concretization. (2) Metacognition is the highest level processing operation. It plays a role in planning, supervising and adjusting to the other mind operations in the whole knowledge task process.(3) By and large, it's consistent in using mind operation modes between different gender and subject (art or science) of knowledge workers.(4) It could recognize and classify the types of knowledge task from the angle of mind operation modes.The description and representation of knowledge task process has provided sustain to knowledge task method-optimization and time-mensuration. It not only has basic significance in management science and knowledge management work efficiency, but also implies discussion of artificial intelligence knowledge representation method. It has innovative significance in theory and practice.
