Signature representation of data with aliasing across synonyms

摘要

A system and method for generating an m -dimensional signature vector with aliasing across synonyms in a computing device is provided. Data representable by a plurality of key-value pairs, each comprising a unique identifier and an associated non-zero value of n-dimensional data is received at the computing device. Elements of the m -dimensional aliased signature vector are generated using synonym information of keys from the plurality of key-value pairs.
