Klingbiel, Paul H. – Information Storage and Retrieval, 1973
To index at the Defense Documentation Center (DDC), an automated system must choose single words or phrases rapidly and economically. Automation of DDC's indexing has been machine-aided from its inception. A machine-aided indexing system is described that indexes one million words of text per hour of CPU time. (22 references) (Author/SJ)

Wall, R. A. – Information Storage and Retrieval, 1973
A proposal for a computer-aided method of building up an indexing language is made. The method involves linking terms relevant to any special retrieval system into the UDC, via a video terminal, producing a hybrid thesaurus-classification. (5 references)

Mackenzie, Claude Ainsley – Information Storage and Retrieval, 1973
An investigation has been made of the suitability of Farradane's system of relational indexing as a German language indexing tool. A circular representation of Farradane's table of relations is proposed and the German version of relational indexing is presented and discussed. (12 references) (Author)

Klingbiel, Paul H. – Information Storage and Retrieval, 1973
The technique for machine-aided indexing developed at the Defense Documentation Center (DDC) is illustrated on a randomly chosen abstract. Additional text is provided in coded form so that the reader can more fully explore this technique. (2 references) (Author)

Tharp, Alan L. – Information Storage and Retrieval, 1973
The author describes a method of automatic indexing using the assignment of priority to verbs which may also be viewed as a simulation of how a person classifies documents. (15 references) (Author/SJ)
