Abstract
A mapping function is used to identify one or more entries of a probabilistic data structure to be updated to indicate a presence of a particular term in a text record. Some entries of the data structure may correspond to more than one term. The data structure is used as input for a machine learning algorithm which provides an indication of similarity between the text record and other text records.
