Abstract : CLASSIFIER is an automated computer-oriented information classification system which provides a library structure for information as well as document retrieval. The information content of the document is classified at levels of detail ranging from the document to a sentence. Statistically determined measures of relevance indicative of the degree of association of each unit of information with respect to each class of the hierarchy are defined. The more frequently a word is used in a class, rather than in general usage, the greater the association with that class. Conversely, the less frequencly a word is used in a class, rather than in general usage, the less association with that class. The result is a series of lists of units of information for each class of the hierarchy, rated in order of decreasing relevance. Inherent in the classification process is the ability to select index terms for the units of information to complement the hierarchal structure. Nonstatistical measures can supplement the statistical techniques if desirable. (Author)
