Retrieval Performance of a KWOC Index to the 1498 Work Unit Summary Data Base,

Abstract

The retrieval performance of a technique for automated indexing using a controlled vocabulary (machine-aided indexing) is compared with that of a Key Word Out of Context index (KWOC). Twenty subject searches were performed using a data base of 635 summaries of Defense management data. Results show an average recall measurement of .73 for machine-aided indexing and .79 for the KWOC index. The average relevance measurements were .62 for machine-aided indexing and .60 for the KWOC index. (Author)
