Formal concept analysis for system awareness of operators

This paper proposes a logical framework that visualizes worker´s system awareness. Generally, this awareness is difficult to compile in a educational book, and is seldom communicated in verbally. To show broad utility of system awareness, we need to show operator´s conceptual structure of system operating. We firstly carry out operation analysis of graph drawing task using a spreadsheet software. Based on it, we propose a logical representation of operator´s system awareness using Formal Concept Analysis. Using this framework, we analyze the correspondence relations of difference of using functions for each operator and implication from formal concept. As a result, this representation shows the operators´ implicit rules which become the selection criteria of system functions.
