EVENTS LEADING TO A DECISION TO ADOPT THE SYSTEM, SOME THEORY OF INDEXES, PROBLEMS INVOLVED IN CONVERSION, AND SOME OF THE RESULTS ACHIEVED ARE REVIEWED. UNIDEK MAKES…

Symbols for bibliometric concepts like "half life,""impact factor,""normalized impact factor," and "immediacy index" are proposed and formulas for the determination of their values are provided. The features of the bibliometric concepts are also highlighted. (Author/AEF)

Selection and acquisition of relevant materials for building and developing an information infrastructure are modern worldwide problems. This document provides a core listing of journals in the earth sciences in an effort to develop a tool for the improvement of information handling and transfer. The core list was generated using several databases…

Work has been performed on a fully automated approach for the general categorization of documents based on a training set of document titles and abstracts and journal-level indexing of the journals in which the documents are published.
