Abstract:

DTIC has conducted an experiment that utilizes the free text inversion technique to retrieve records from the Technical Reports data base. It was felt that free text inversion as a form of retrieval would be beneficial in supporting DTICs revitalized role in the transfer of technical information. The intent of this project was to determine if the free text inversion technique could be implemented on the DROLS on-line system without severely impacting the on-line systems storage capacity and to determine whether the added capability could improve upon or replace the present practice of using open-endedidentifier indexing terminology. Based on the results of the experiment, it was determined that searching of DTICs Technical Reports data base is a viable retrieval technique that will provide searchers with an additional enhancement that can be used to augment DTICs present retrieval methods. However, evidence that will support the use of free text in lieu of the use of identifiers and open-ended terminology remains inconclusive. Additional data collected in a live environment will have to be analyzed before a conclusion can be made concerning the use of open-ended terminology.
