Base Claim:
1. A method for determining signal similarity between a query signal and a reference signal via composition, the method comprising: searching said reference signal to detect at least one matching region to a region of said query signal, the shape and size of said matching region being determined as a function of a local evidence score for said region, wherein said local evidence score is a function at least of a quality of the match of said region and of its statistical significance; and composing at least part of said query signal from at least one said matching region which provides at least one of: local evidence scores and a global evidence score for said query signal; wherein said global evidence score defines the extent of a global similarity of said query signal to said reference signal.

Claim 15:
15. The method according to claim 1 and wherein said global evidence score (GES) is defined as at least one of: GES ⁢ ( Q | H ref ) = log ⁢ ⁢ P ⁡ ( Q | H ref ) P ⁡ ( Q | H 0 ) = log ⁢ ⁢ ∑ S ⁢ P ⁡ ( Q | H ref , S ) ⁢ P ⁡ ( S | H ref ) P ⁡ ( Q | H 0 ) = log ⁢ ⁢ ∑ S ⁢ P ⁡ ( S | H ref ) ⁢ ⁢ P ⁡ ( Q | H ref , S ) P ⁡ ( Q | H 0 ) where P indicates a probability function, H ref is the hypothesis that a region R was generated by reference REF, H 0 is the null hypothesis, Q is said query signal and S is a segmentation of Q; and also comprising: computing at least one of an upper bound on GES(Q|H ref ) and a lower bound on GES(Q|H ref ).
