摘要:An approach is provided for efficiently searching information in an informationspace utilizing information signatures. A signature application receives queries overinformation sources. The signature application, for each of the queries, generates apolynomial by defining the each query against the information sources as inputparameters in polynomial form. The signature application provides irreduciblepolynomials over a finite field of a degree of orthogonality by factoring polynomialsgenerated from the queries. The signature application adjusts the degree of
orthogonality of the irreducible polynomials to provide adjusted irreducible polynomials,each of which is a signature and corresponds to a signature fragment, such that thesignature fragments have overlapping portions. The signature application causes at leastin part storage of the signatures or the signature fragments in a signature domain overan information space.
