Abstract: The “relevant” participants for each person in an online meeting may be automatically identified and a personalized view created to dynamically represent these relevant people as the meeting progresses. Relevancy of participants may be determined based on a number of factors and data from a variety of sources at the initialization of the meeting or when the participant for whom the personalized view is created joins the meeting. The relevancy computation may be updated and the personalized view dynamically changed during the meeting based on changes in participants, their participation modality, and comparable factors.
