    Abstract
    The inverse document frequency (IDF) and signal-noise ratio (S/N) approaches are term weighting schemes based on term specifics. However, the existing justifications for these methods are still some what inconclusive and sometimes even based on incompatible assumptions. Introduces an information-theoretic measure for term specifics. Shows that the IDF weighting scheme can be derived from the proposed approach by assuming that the frequency of occurrence of each index term is uniform within the set of documents containing the term. The information-theoretic interpretation of term specifics also establishes the relationship between the IDF and S/N methods
