UMDL Service Classifier Agent Demo

Introduction

• Validity. The system responds accurately to meet user requests and needs.

• Scalability. A large society with many agents performs effectively through appropriate use of agent capabilities.

• Extensibility. New agents can be utilized by the UMDL society without modification of existing agents.

The SCA is the first application of the UMDL ontology. The ontology provides a language for describing UMDL activity that is independent of the particular current implementation of UMDL agents. Therefore, client agents seeking services should describe their requirements with as much precision as is supported by the ontology, even if currently existing agents can not be differentiated according to all of the features of the client's description. In the future new agents may be developed which are more specialized. Using the SCA, the new specialized agent will be selected to service the client, even without making any changes to the client's implementation.

Demo

• Start the SCA, if one is not already active.

• Classify a service description.

• Query classified agent services.

• Display the history of the current SCA.

• Shut down the SCA (requires a password).

Documentation

Classification and query requests must be formulated with syntax based on the Loom description logic classification system, and using concepts and relations translated from the UMDL ontology to Loom. The following documentation is available:

• Service Classifier Agent Programmer's Interface.

• UMDL Ontology Concepts and Relations available to the Service Classifier Agent.
