K2 Layer

The client application communicates directly with the K2 layer, connecting to either a K2 Server or a K2 Broker (which in turn connects to one or more K2 Servers). The K2 Server/Broker architecture provides distributed, scalable, secure, and fault-tolerant access to Verity’s core and advanced capabilities. See Deployment Architecture for more information on K2 Server and K2 Broker.

The K2 Server makes use of advanced Verity features and capabilities within the K2 layer. These features include:

Administration, security, and distributed indexing services, as described in Setting Up a Verity K2 Installation.


Content services such as knowledge tree creation, parametric-index creation, and the use of the Recommendation Engine and Logistic Regression Classifier, as described in Classifying Information and Providing Recommendations.
