A new approach to information retrieval problems in separations science

Retrieving information on specific chemical separations is among the most difficult problems in information management, although the ability to find methods to cleanly and efficiently separate chemical species is of the utmost importance to chemists and chemical engineers. Information on performing specific chemical separations is largely buried in the literature of dozens of branches of science. Most methods of indexing (both hard copy and computer) do not provide good means of retrieving information on specific separations because index terms such as extraction, leaching, chromatography, and even ion exchange have different meanings in different disciplines. Recent attempts to solve some of the problems of information retrieval in separations science have resulted in the concept of a Separations Science Data Base. This data is designed for the chemical separations information and contains unique indexes that allow rapid and accurate retrieval of information about specific separations from specific matrices and a method of minimizing false returns that result from cross coupling of unrelated terms in multisubject reports. Although the data base is presently only about 20% complete, the success of this work has been encouraging and further work is indicated.
