INTELLIGENCE ANALYSIS METHOD AND SYSTEM
First Claim
1. A method of analysis of competing hypotheses, said method comprising the steps of:
- a. deciding on possible hypotheses to be considered;
b. identifying significant items of evidence for and against each hypothesis;
c. constructing a model for analysing the hypotheses by;
i. producing a set of exhaustive and exclusive hypotheses, wherein only one hypothesis may be true;
ii. assessing and assigning base rates for each hypothesis;
iii. determining a set of items of evidence that are relevant to, have a causal influence on or would disconfirm more than one hypothesis;
iv. assessing and assigning base rates for each item of evidence;
v. deciding for each item of evidence whether the item should be treated as being a causal influence or diagnostic indicator with respect to the set of the hypotheses;
vi. if the item of evidence is to be treated as a causal influence—
making a judgement as to the likelihood of each hypothesis;
A. if the evidence were true, andB. if the evidence were false;
vii. if the item of evidence is to be treated as a diagnostic indicator—
making a judgement as to the evidence being true;
A. if the hypothesis were true;
d. assessing the belief for each item of evidence being true;
e. deciding a set of interim beliefs in each hypothesis for each individual item of evidence by;
i. employing a conditional inference operator for evidence that is to be treated as a causal influence; and
ii. employing a reverse conditional inference operator for evidence that is to be treated as a diagnostic indicator; and
f. deciding the overall belief in each hypothesis by employing a consensus operator on the respective set of interim beliefs.

Abstract
Method of and system for analysing a set of exhaustive and exclusive hypotheses, including assessing and assigning base rates for each hypothesis; determining a set of items of evidence that are relevant to, have a causal influence on, or would disconfirm more than one hypothesis; assessing and assigning base rates for each item of evidence; deciding, for each item of evidence, whether the item should be treated as being a causal influence or diagnostic indicator with respect to the set of the hypotheses; if the item of evidence is to be treated as a causal influence—making a judgement as to the likelihood of each hypothesis, both if the evidence were true, and also if the evidence were false; if the item of evidence is to be treated as a diagnostic indicator—making a judgement as to the evidence being true if the hypothesis were true; assessing the belief for each item of evidence being true; deciding a set of interim beliefs in each hypothesis for each individual item of evidence by:
- employing a conditional inference operator for evidence that is to be treated as a causal influence; and
- employing a reverse conditional inference operator for evidence that is to be treated as a diagnostic indicator; and
deciding the overall belief in each hypothesis by employing a consensus operator on the respective set of interim beliefs.

11. A method of analysing a set of exhaustive and exclusive hypotheses, said method comprising the steps of.
assessing and assigning base rates for each hypothesis; -
determining a set of items of evidence that are relevant to, have a causal influence on or would disconfirm more than one hypothesis; assessing and assigning base rates for each item of evidence; deciding, for each item of evidence, whether the item should be treated as being a causal influence or diagnostic indicator with respect to the set of the hypotheses; if the item of evidence is to be treated as a causal influence—
making a judgement as to the likelihood of each hypothesis, both if the evidence were true, and also if the evidence were false;if the item of evidence is to be treated as a diagnostic indicator—
making a judgement as to the evidence being true if the hypothesis were true;assessing the belief for each item of evidence being true; deciding a set of interim beliefs in each hypothesis for each individual item of evidence by; employing a conditional inference operator for evidence that is to be treated as a causal influence; and employing a reverse conditional inference operator for evidence that is to be treated as a diagnostic indicator; and deciding the overall belief in each hypothesis by employing a consensus operator on the respective set of interim beliefs. - View Dependent Claims (14)

13. A system for analysing a set of exhaustive and exclusive hypotheses, said system comprising at least one processor for executing instructions, memory means coupled to the processor, storage means for reading media having sequences of instructions stored thereon coupled to the storage means, input/output means for delivering data to and/or from the memory or storage means and user interface means allowing for interaction with said instruction sequence, which sequence also causes said at least one processor to execute the steps of.
assessing and assigning base rates for each hypothesis; -
determining a set of items of evidence that are relevant to, have a causal influence on or would disconfirm more than one hypothesis; assessing and assigning base rates for each item of evidence; deciding, for each item of evidence, whether the item should be treated as being a causal influence or diagnostic indicator with respect to the set of the hypotheses; if the item of evidence is to be treated as a causal influence—
making a judgement as to the likelihood of each hypothesis, both if the evidence were true, and also if the evidence were false;if the item of evidence is to be treated as a diagnostic indicator—
making a judgement as to the evidence being true if the hypothesis were true;assessing the belief for each item of evidence being true; deciding a set of interim beliefs in each hypothesis for each individual item of evidence by; employing a conditional inference operator for evidence that is to be treated as a causal influence; and employing a reverse conditional inference operator for evidence that is to be treated as a diagnostic indicator; and deciding the overall belief in each hypothesis by employing a consensus operator on the respective set of interim beliefs.
