A method and system for computer-assisted analysis of information from a data source employs operators including search terms and filters. A visual representation of a network of operators is generated, the operators being user selectable and linked to form the network, which is configured to analyze information from a selectable data source. The network of operators can be compiled as a unit. If the data source includes a database, the operators are applied to the database, and if the data source includes a data stream, a data unit of the data stream is evaluated with the operators. An output indicator corresponding to each of the operators is generated on the visual representation of the network, wherein the output indicator visually represents a quantified output of a corresponding operator. A further output corresponding to one or more of the output indicators is also generated.
