METHOD OF AND SYSTEM FOR GENERATING A HASHED COMPLEX VECTOR

摘要

A computer-implemented method (600) of and a system (220, 222, 224) for generating a hashed complex vector (360) indicative of an association between a document and a parameter of interest, the document being associated with first data (343) and second data (349). The method comprises accessing (602) the first data (343); accessing (604) the second data (349) the second data being a category type; generating (606), by a processor, a mask vector based on the first data; generating (608) a hash vector; generating (610) a complex vector (350) comprising the mask vector and the hash vector; generating (612) a hashed complex vector by applying a second hash function (H2) to the complex vector (350); and storing (614) the hashed complex vector (360).
