A semantic network, or frame network is a knowledge base that represents semantic relations between concepts in a network. This is often used as a form of knowledge representation . It is a directed or undirected graph consisting of vertices , which represent concepts , and edges , which represent semantic relations between concepts , [ 1 ...
The salience network is theorized to mediate switching between the default mode network and central executive network. [1] [2]The salience network (SN), also known anatomically as the midcingulo-insular network (M-CIN) or ventral attention network, is a large scale network of the human brain that is primarily composed of the anterior insula (AI) and dorsal anterior cingulate cortex (dACC).
Systems theory is the transdisciplinary [1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial.Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.
Spreading activation is a method for searching associative networks, biological and artificial neural networks, or semantic networks. [1] The search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes.
Interest structures: pattern of relations between goals and desires of people of varying social positions; Interaction structures: forms of communication of people of varying social positions; Modern sociologists sometimes differentiate between three types of social structures: Relation structures: family or larger family-like clan structures
An organizational structure defines how activities such as task allocation, coordination, and supervision are directed toward the achievement of organizational aims. [1] Organizational structure affects organizational action and provides the foundation on which standard operating procedures and routines rest.
A nomological network (or nomological net [1]) is a representation of the concepts of interest in a study, their observable manifestations, and the interrelationships between these. The term " nomological " derives from the Greek , meaning "lawful", or in philosophy of science terms, "law-like".
The hierarchical network model is part of the scale-free model family sharing their main property of having proportionally more hubs among the nodes than by random generation; however, it significantly differs from the other similar models (Barabási–Albert, Watts–Strogatz) in the distribution of the nodes' clustering coefficients: as other models would predict a constant clustering ...
