IDOL server can automatically provide users with a set of hierarchical channels with highly relevant information pertinent to the respective channel. Channels are similar to agents, aggregating information that is relevant to the channel concept. Usually, administrators set up channels that are available to all users.
Real-time information dynamically updates in the channels. This process eliminates the requirement for manual intervention or pretagging, and minimizes the effort required to maintain it. Moreover, the administrator can add and remove channels on the fly, without recategorizing all the data.
You can set up channels in Autonomy Retina’s Category Administration or Autonomy’s Category Administration Tool portlet. Users can access channels through Autonomy Retina’s Channels page or Autonomy’s Channels portlet.
Refer to the Retina Administration Guide or Portlets Administration Guide for details.
