Evaluation of the Selective Dissemination of Information (SDI) Program for the Aerospace Materials Information Center.
Scheffler, F. L.; March, J. F.
The Aerospace Materials Information Center (AMIC) Selective Dissemination of Information (SDI) program was evaluated by an interview technique after one year of operation. The data base for the SDI consists of the periodic document index records input to the AMIC system. The users are 63 engineers, scientists, and technical administrators at the Air Force Materials Laboratory (AFML) and 16 scientific and technical personnel at the University of Dayton. An informal interview technique elicited responses regarding the user assessment of the program and also indicated problem areas in the returns received by the users from the SDI profiles. Most respondents indicated that too many abstracts were being received and too low a relevance was occurring. Refinement of the profiles based on more precise statements obtained from the interviews and on rejected abstracts increased the overall relevance from 37.6% to 51.8%. The primary factor in the improvement was the judicious but copious use of NOT terms to eliminate unwanted abstracts. Results showed the validity of the NOT strategy and indicated the effectiveness of direct contact between the information specialist and the SDI user in getting uninhibited feedback and obtaining meaningful expressions of user technical interests.
