The VectorDistance function takes a table of target vectors and a table of reference vectors and returns a table that contains the distance between each target-reference pair.



Information retrieval and text mining applications use the vector distance between the Term Frequency Inverse Document Frequency (TF-IDF) representations of two documents to measure the similarity of their subject matter.
