Intrex Subject/Title Inverted-File Characteristics.
The characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and low frequency is also reported. All characteristics are discussed and analyzed in connection with the free vocabulary, in-depth indexing method of Intrex. (Author)
