15. The system of claim 14 , wherein the instructions to resolve each of the plurality of target vector dimensions associated with multiple possible magnitudes to an actual magnitude based on a feature of a respective source vector dimension of the single-magnitude source vector cause the processor to: test the feature of the respective source vector dimension of the single-magnitude source vector based on a morphological characteristic of the feature, a syntactic characteristic of the feature, a proximity of a first source vector dimension to a second source vector dimension, a frequency of appearance of one or more source vector dimensions, time or date information associated with the source vector, an originating location of the source vector, a location of an event described in a source document, a location of analysis of a source document, purpose for analyzing the source document, or a combination thereof.
14. A system for performing vector comparison in natural language processing, the system comprising at least one processing unit coupled to a memory, wherein the memory is encoded with computer executable instructions that, when executed, cause the at least one processing unit to: receive a single-magnitude source vector including a plurality of source vector dimensions each of the plurality of source vector dimensions comprising a source word or phrase, and a multi-magnitudinal target vector including a plurality of target vector dimensions, each of the plurality of target vector dimensions comprising a target word or phrase, wherein each source vector dimension of the plurality of source vector dimensions is associated with a single possible magnitude and one or more of the target vector dimension of the plurality of target vector dimensions is associated with multiple possible magnitudes, wherein each of the magnitudes comprises a weight; determine which of the plurality of target vector dimensions are associated with multiple possible magnitudes; resolve each of the plurality of target vector dimensions associated with multiple possible magnitudes to an actual magnitude based on a feature of a respective source vector dimension of the single-magnitude source vector; and compare the target vector with the source vector to obtain a similarity measure.
