Abstract

There is provided an automated negotiation agent 1 and method of evaluating risk and trust from different contractual viewpoints during electronic negotiation of contracts, preferably e-contracts, in a business to business environment. The negotiation agent 1 on receiving a contract proposal from another agent 15, analyses the contract proposal from different viewpoints to determine measures of the risk and trust involved. A response 20 is formulated from the measures of risk and trust, and is returned to the other agent 15. The negotiation agent 1 has an evaluation engine 9 which evaluates the risk and viewpoints for the contract proposal by accessing a risk and trust functions and viewpoints database 4, a contract template database 2, a contract context database 13 and contract history repository 10. The negotiation agent also has a negotiation engine 8 that evaluates the effect of the contract proposal from different levels using the risk and trust viewpoints received from the evaluation engine 9. The negotiation engine 8 is driven by a utility function and can access the contract template database 2 and the contract history repository 10 during its evaluation. The response returned to the other agent 15 is dependant on the evaluation and is output by the negotiation engine 8.

Claims

1. A method of determining risk and trust for electronic negotiation of contracts, comprising:

receiving a contract proposal from a negotiation agent;

analysing the contract proposal using a contract template and from different viewpoints to determine measures of the risk and trust involved;

formulating a response from the measures of risk and trust to send to the negotiation agent; and

returning the response to the negotiation agent.

2. A method according to claim 1, wherein all the steps are conducted in real-time.

3. A method according to claim 1, wherein the step of analysing the contract proposal from different viewpoints is carried out in the context of all contract terms and conditions comprising the contract proposal.

4. A method according to claim 1, wherein the step of analysing the contract proposal from different viewpoints is carried out in the context of past contract proposals.

5. A method according to claim 1, wherein the step of analysing the contract proposal from different viewpoints is carried out at the level of aggregations of claims of the contract proposal.

6. A method according to claim 1, wherein the step of analysing the contract proposal from different viewpoints is carried out at the level of each claim of the contract proposal.

7. A method according to claim 1, wherein the step of analysing the contract proposal comprises:

associating metadata to contract templates and to aggregations of contract templates to describe risk functions and trust functions for the contract proposal; and

determining each viewpoint from one or more of the risk and the trust functions.

8. A method according to claim 7, wherein the step of associating metadata further comprises:

implementing the risk and the trust functions using a macro, a script or a set of rules.

9. A method according to claim 7, wherein the risk functions evaluate the risk involved for the contract proposal from a calculus of the trustworthiness of all information received from external sources such as the negotiating agent by using trust functions.

10. A method according to claim 7, wherein the trust functions evaluate the trust involved for the contract proposal from an examination of contextual risks by using risk functions.

11. A method according to claim 3, further comprising:

calculating risk mitigation tactics on the basis of analysis of the measures of risk and trust involved for the contract proposal using a negotiation engine, whereby the step of formulating a response is influenced by the risk mitigation tactics.

12. A method according to claim 11, wherein the risk mitigation tactics comprise:

requesting trusted information as a risk mitigation tactic.

13. A method according to claim 11, wherein the risk mitigation tactics comprise:

requesting re-negotiation of particular contract terms as a risk mitigation tactic.

14. A method of determining risk and trust for electronic negotiation of contracts, comprising:

receiving a contract proposal from a negotiation agent;

analysing the contract proposal using a contract template and from different viewpoints by associating metadata to contract templates and to aggregations of contract templates to describe risk functions and trust functions for the contract proposal; and

determining each viewpoint from one or more of the risk and the trust functions to determine measures of the risk and trust involved;

formulating a response from the measures of risk and trust to send to the negotiation agent; and

returning the response to the negotiation agent.

15. A method of determining risk and trust for electronic negotiation of contracts, comprising:

receiving a contract proposal from a negotiation agent;

analysing the contract proposal using a contract template and from different viewpoints in the context of all contract terms and conditions comprising the contract proposal to determine measures of the risk and trust involved;

calculating risk mitigation tactics on the basis of analysis of the measures of risk and trust involved for the contract proposal using a negotiation engine;

formulating a response from the measures of risk and trust and influenced by the risk mitigation tactics, to send to the negotiation agent; and

returning the response to the negotiation agent.

16. A negotiating agent for measuring risk and trust in real time during electronic negotiation of contracts comprising:

an evaluation engine for receiving a contract proposal and evaluating the risk and trust viewpoints for the contract proposal;

a risk and trust functions and viewpoints store for storing metadata associated with contract templates, and accessible by the evaluation engine for evaluating the risk and trust viewpoints;

a contract context store for storing contextual data associated with contract negotiation, and accessible by the evaluation engine for evaluating the risk and trust viewpoints;

a negotiation engine for receiving risk and trust viewpoints from the evaluation engine, and driven by a utility function for evaluating the effect of the contract proposal from different levels;

a contract template store for storing metadata associated with contract templates, and accessible by the evaluation engine for evaluating the risk and trust viewpoints and accessible by the negotiation engine for evaluating the effect of the contract proposal; and

a contract history repository for storing data associated with past contracts, and accessible by the evaluation engine for evaluating the risk and trust viewpoints and the negotiating engine for evaluating the effect of the contract proposal, wherein the negotiation engine is configured for outputting a response that is dependent on the evaluation of the effect of the contract proposal.

17. A negotiating agent according to claim 16, wherein the evaluation engine comprises:

an interpreter for retrieving relevant metadata from the functions and viewpoints store and for interpreting risk and trust functions at different levels of abstraction as defined by metadata; and

a trust/risk viewpoints manager for composing measures of risks and trusts at different levels of abstraction by aggregating and correlating functions.

18. A computer readable storage medium storing instructions that, when executed by a computer, cause the computer to perform a method of determining risk and trust for contracts under electronic negotiation by receiving a contract proposal from a negotiation agent;

analysing the contract proposal using a contract template and from different viewpoints to determine measures of the risk and trust involved;

formulating a response from the measures of risk and trust to send to the negotiation agent; and

returning the response to the negotiation agent.

19. A messaging protocol for relaying inter-agent communications between negotiating agents to permit sending of a response to a negotiation agent in a method comprising receiving a contract proposal from a negotiation agent;

analysing the contract proposal using a contract template and from different viewpoints to determine measures of the risk and trust involved;

formulating a response from the measures of risk and trust to send to the negotiation agent; and

returning the response to the negotiation agent.
