Objective decision making application using bias weighting factors
A method and system for implementing a weighted belief network that assists collaborative users in making decisions. A belief network structure is employed that further includes user controlled weighting and biasing factors to adjust the probabilities for the various nodes. The various participants have the opportunity to make adjustments to the weighting and credibility of the evidence and participants in the decision making process in order to arrive at what may be perceived as a more objective outcome. As the collaborative environment is established and the belief network is built, each user can apply various weighting and bias scenarios from their own perspective thereby allowing each discrete user to work out their various suspicions regarding the bias of other participants or the actual weight of a discrete piece of supporting evidence in the context of the entire belief network.
1. A collaborative decision making system, comprising:
a communication network;
at least two user interfaces connected to said communication network; and
a decision making process accessed by users via said user interfaces, said decision making process performed by an algorithm that operates to:
identify a problem to be solved;
identify a plurality of possible outcomes for said problem to be solved;
structure said plurality of possible outcomes into a belief network;
solicit evidence from said users relating to said outcomes;
generate a probability table containing a conditional probability based on said evidence for each of the possible outcomes wherein beliefs in the confidence level of an outcome is obtained from each user and entered in said probability table; and
apply a selective weighting factor to add or remove from consideration evidence based on a discrete user that submitted the evidence to adjust the conditional probability for each of the possible outcomes.
2. The system of claim 1 , wherein said weighting factor is a real number between 0 and 1.
3. The system of claim 1 , wherein said weighting factor is a user determined value that adjusts the weight given to the evidence submitted by a selected user.
4. The system of claim 1 , wherein the user interface includes a display wherein said decision making system is graphically displayed and said weighting factor is adjusted by a user using a graphic user interface.
5. The system of claim 1 , wherein said at least two user interfaces are a plurality of user interfaces allowing a plurality of users to access said decision making process.
6. The system of claim 1 , wherein the communication network is the Internet.
7. The system of claim 1 , wherein said algorithm operates on one of said user interfaces.
8. The system of claim 1 , wherein said algorithm operates on a processor connected to said communication network.
9. A computer implemented method for collaborative decision making, comprising:
identifying a problem to be solved;
identifying a plurality of possible outcomes for said problem to be solved;
structuring said plurality of possible outcomes into a belief network, said belief network residing on a computer processor in communication with an electronic communication network;
soliciting evidence from a plurality of users relating to said outcomes, said users inputting said evidence via a user interface in communication with said electronic communication network;
said processor generating a probability table containing a conditional probability based on said evidence for each of the possible outcomes wherein evidence in the form of beliefs in the confidence level of an outcome is obtained from each user and entered in said probability table; and
said users applying a selective weighting factor to add or remove from consideration evidence based on a discrete user that submitted the evidence to adjust the conditional probability for each of the possible outcomes.
10. The method of claim 9 , wherein said weighting factor is a real number between 0 and 1.
11. The method of claim 9 , wherein each user can selectively apply a weighting factor to adjust the weight given to any of said evidence submitted by any of said plurality of users.
12. The method of claim 9 , wherein the communication network is the Internet.
13. The method of claim 9 , wherein said computer implemented method is a software application that operates on one of said user interfaces.
14. The method of claim 9 , wherein said computer implemented method is a software application that operates on a processor connected to said communication network.
15. The method of claim 9 , wherein the user interface includes a display wherein said decision making system is graphically displayed and said weighting factor is adjusted by a user using a graphic user interface.
