Abstract:
1. A method of predicting a property of a target object via receiving an input query to search manager apparatus coupled to a plurality of databases, the processor search manager apparatus comprising a processor and memory, the method comprising: receiving first property data for at least one first database for a plurality of objects; generating said at least one first database of the first property data for the plurality of objects, an object being described by a vector of attributes, an attribute comprising a real value; analyzing via said processor of said search manager apparatus the attributes utilizing multivariate statistical analysis to determine a subspace of an attributes space, the subspace having at least two dimensions, the attributes space having a greater number of dimensions than said subspace; clustering via said processor the objects into groups of objects where a measure of similarity between objects comprises projecting attribute vectors onto the attributes subspace, the similarity measure being a result of applying similarity-based indexing between points in the attributes subspace; determining projections via said processor onto a subspace for clustering and indexing objects in said groups of objects in relation to the target object by the similarity measure; searching said objects via a query of the at least one first database using the similarity measure for objects similar to the target object; applying at least two models for utilizing currently stored property data for the objects similar to the target object and adapting the applied two models for the target object, the target object being different from any of the plurality of objects of the at least one first database; and predicting the property of the target object responsive to said clustering and indexing by the similarity measure utilizing the applied at least two models corresponding to alternative hypotheses and selecting one of the alternative hypotheses to obtain said predicted property.
