Abstract
According to embodiments of the present disclosure, a keyword frequency analysis system stores a plurality of sets of records. Each set of records may be associated with a dimension and may comprise a first keyword and a second keyword. The system may also receive the plurality of sets of records, determine a frequency of the first keyword in each set of records and determine a frequency of the second keyword in each set of records. The system may further determine an expected frequency of the first keyword in a first set of records associated with a first dimension, based on the frequency of the first keyword and the frequency of the second keyword. The system also compares the frequency of the first keyword and the expected frequency and, based on the comparison, determines whether the first keyword is either overrepresented or underrepresented in the first set of records.
