Figure 1

Illustrating the Step-by-Step Process of Eccentricity Calculation Within a Social Network. Participants in a social network are connected to a subset of other participants forming a social neighborhood. (a) Each participant can access the ideas generated in the social neighborhood. (b) The ideas are vectorized using Doc2Vec. Recent ideas posted in the social neighborhood of a participant (by the participant and their neighbors) constitute the Knowledge Base for the participant. (Every participant has a separate knowledge base, which is updated when a new idea is posted in the neighborhood). (c) To measure the eccentricity of a newly generated idea, distance between new idea (vector) and the center of the knowledge base is measured. The intensity of red color represents the distance from the center of the knowledge base (which is, by definition, the eccentricity).
