Version V1

This data collection contains the DICTION program, a multi-option, high-speed, content-analysis program that retrieves cognitive, affective, and decisional data from speeches, documents, or archival materials. This computer analysis of textual themes by cluster-analysis technique is designed for use with Robert North et al., BRITISH SPEECHES, 1870-1914, AND GERMAN SPEECHES, 1871-1912 (ICPSR 5902). DICTION is used to produce word-frequency dictionaries, to substitute equivalent words into and delete unwanted words from the text, and to count the co-occurrences of pairs of specified keywords in text input. DICTION also includes routines to delete common English suffixes from text words. It is written in Fortran IV for use with the IBM H Compiler (OPT = 2).
