# Agents

Users can create agents in IDOL Server to find and monitor information that is relevant to their interests. The agents collect this information from a configurable list of Internet and intranet sites, news feeds, chat streams, and internal repositories.

You can create agents in a user-friendly way using:

- Natural language descriptions

- Example content (point and click)

- Legacy keyword or Boolean expressions

IDOL Server provides the conceptual information that it needs to create agents. The server accepts a piece of content (training text, a document, or a set of documents) or reference (identifier), and returns an encoded representation of the concepts. This representation includes the specific underlying patterns of terms and associated probabilistic ratings for each concept.

Users can retrain their agents by submitting a new piece of content (training text, a document, or a set of documents). The server uses the new concepts to adapt the agent.
