The Situation Awareness Weighted Network (SAWN) model and method: Theory and application

Cognitive Ergonomics Evaluation Assisted by an Intelligent Emotion Recognition Technique

“…According to the authors of [30][31][32][33], creating a proper environment to motivate employees will increase their satisfaction, performance, and productivity. According to the authors of [27][28][29], situation awareness (SA) is the knowledge and understanding of specific situations or environments. SA is described as the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future.…”

Weighted networks in socio-technical systems: Concepts and challenges

“…Since these systems are based on people and technological infrastructure, various networks may be identified that reflect relations between people, people and technical objects, and between technical objects. Networks containing people and technical objects have been researched in domains such as education [16,17], behavioral change for energy saving [18], sustainable urban water management [19,20], health care systems focused on e-Health interoperability [21] or personal health technology [22], social networks [23], resource sharing in social communication [24], large-scale socio-technical systems on the Web [25], air traffic management systems [26], transit service networks [27], roadside air quality control [28], traffic forecasting [29], work of military staff in steady-state and crisis threat scenarios [30], or software development projects [31,32].…”

“…Kalloniatis et al [30] proposed empirically derived Situation Awareness Weighted Network (SAWN) model, which is based on Situation Awareness model proposed by Endsley [41] involving perception, comprehension and projection, and Distributed Situation Awareness model proposed by Stanton et al [42] indicating that situation awareness exists in a social and semantic network of people and information objects. The SAWN model represents a target socio-technical system as a weighted semi-bipartite network of interactions between people (human nodes) and information artefacts (product nodes).…”

“…In heterogeneous networks, nodes and links can be of variety types depending on the domain modeled with the network. In many cases, vertices can present entities of different types in the same network, such as persons, resources and knowledge [32,36], data and functions in software migration project [40], or humans and information product artefacts [30].…”

“…A weight function of a network models differentiation among the edges. They can be obtained by using statistical observations and analysis [34,35,39,43,45], by measuring real-time data [28,44], by analyzing and quantifying triangulated data from the interaction context [37], by examining knowledge level of people in the network [32], or by using models such Situation Awareness model proposed by Endsley [41] that is used in [30]. In addition, weights can be predefined [40].…”
