Automatic Indexing Using Term Discrimination and Term Precision Measurements
No Access Until
A variety of abstract automatic indexing models have been developed in recent times in an effort to produce indexing methods that are both effective and usable in practice. Among these are thee term discrimination model and the term precision system. These two indexing systems are briefly described and experimental evidence is cited showing that a combination of both theories produces better retrival performance than either one alone. Appropriate conclusions are reached concerning viable automatic indexing procedures usable in practice.
