BitSim: An Algebraic Similarity Measure for Description Logics Concepts
  In this paper, we propose an algebraic similarity measure {\sigma}BS (BS
stands for BitSim) for assigning semantic similarity score to concept
definitions in ALCH+ an expressive fragment of Description Logics (DL). We
define an algebraic interpretation function, I_B, that maps a concept
definition to a unique string ({\omega}_B) called bit-code) over an alphabet
{\Sigma}_B of 11 symbols belonging to L_B - the language over P B. IB has
semantic correspondence with conventional model-theoretic interpretation of DL.
We then define {\sigma}_BS on L_B. A detailed analysis of I_B and {\sigma}_BS
has been given.
