The open agent architecture: A framework for building distributed software systems

Abstract: The Open Agent Architecture (OAA), developed and used for several years at SRI International, makes it possible for software services to be provided through the cooperative efforts of distributed collections of autonomous agents. Communication and cooperation between agents are brokered by one or more facilitators, which are responsible for matching requests, from users and agents, with descriptions of the capabilities of other agents. Thus it is not generally required that a user or agent know the identities, locations, or number of other agents involved in satisfying a request. OAA is structured so as to minimize the effort involved in creating new agents and "wrapping" legacy applications, written in various languages and operating on various platforms; to encourage the reuse of existing agents; and to allow for dynamism and flexibility in the makeup ofagent communities. Distinguishing features of OAA as compared with related work include extreme flexibility in using facilitator-based delegation of com...

Unified messaging methods and systems for communication and cooperation among distributed agents in a computing environment

Abstract: The present invention provides a Unified Messaging system with an emphasis on ubiquitous access and dynamic presentation of the information and services supported by an agent community. The present invention allows queries across dynamically changing, complex information; shared context and reference resolution among applications; and flexible translation of multimedia data. Utilizing an Open Agent Architecture, the present invention allows a user to receive multiple information types, such as email, voicemail, and multimedia data, utilizing a single user interface, such as a phone. Communication and cooperation between agents are brokered by one or more facilitators, which are responsible for matching requests, from users and agents, with descriptions of the capabilities of other agents. It is not generally required that a user or agent know the identities, locations, or number of other agents involved in satisfying a request, and relatively minimal effort is involved in incorporating new agents and “wrapping” legacy applications. Extreme flexibility is achieved through an architecture organized around the declaration of capabilities by service-providing agents, the construction of arbitrarily complex goals by users and service-requesting agents, and the role of facilitators in delegating and coordinating the satisfaction of these goals, subject to advice and constraints that may accompany them.

Software-based architecture for communication and cooperation among distributed electronic agents

Abstract: A highly flexible, software-based architecture is disclosed for constructing distributed systems. The architecture supports cooperative task completion by flexible and autonomous electronic agents. One or more facilitators are used to broker communication and cooperation among the agents. The architecture provides for the construction of arbitrarily complex goals by users and service-requesting agents. Additional features include agent-based provision of multi modal interfaces, including natural language.

Extensible software-based architecture for communication and cooperation within and between communities of distributed agents and distributed objects

Abstract: A distributed agent community is able to dynamically interact with alternative sofware technologies that manage distributed objects. The leveraging of capabilities of distributed object systems greatly expands the flexibility and capabilites of the distributed agent community. Through access to distributed object systems, the distributed agent community can draw on the capabilites of all the objects managed by the distributed object systems. The access to distributed systems by the distributed agent community allows for collaboration and intelligent planning that the distributed object systems do not themsleves provide.

Highly scalable software-based architecture for communication and cooperation among distributed electronic agents

Abstract: A highly flexible, software-based architecture is disclosed for supporting cooperative task completion by flexible, dynamic configurations of autonomous electronic agents. Communications and cooperation between agents are brokered by one or more facilitators. The facilitators employ strategic reasoning for generating a goal satisfaction plan to fulfill arbitrarily complex goals by users and service requesting agents.
