Query: Entropy-based disciplinarity indicator: role taxonomy of journals in
  scientific communication systems and isolation degree. Knowledge
  importation/exportation profiles from journals and disciplines   In this research, a new indicator of disciplinarity-multidisciplinarity is
developed, discussed and applied. EBDI is based on the combination of the
frequency distribution of subject categories of journals citing or cited by the
analysis unit and the spread and diversity of the citations among subject
categories measured with Shannon-Wiener entropy. Its reproducibility,
robustness and consistence are discussed. Four of the combinations of its
values when applied to the cited and citing dimensions lead to a suggested
taxonomy of the role that the studied unit might have in terms of the
transformation of knowledge from different disciplines in the scientific
communication system and its position respect a hypothetical thematic core of
the discipline in which it has been classified. The indicator is applied to the
journals belonging to the first quartile of JCR-SSCI 2011 Library and
Information Science and an indicator-based taxonomy is applied and discussed,
pointing to differential thematic roles of the journals analyzed.
