# Cluster Information

The IDOL Category component can automatically cluster information to make trends and developments in this information visible. Clustering is the process of taking a large repository of unstructured data and automatically partitioning it, so that similar information is clustered together. Each cluster represents a concept area in the knowledge base, and contains a set of items with common properties.

NOTE: The IDOL Category component provides several methods of clustering, including dynamic clustering and index tagging. See Cluster Results, and Tag Documents into Clusters.

For details of all the available types of clustering, and information about which one to choose, refer to IDOL Expert.
