WordStat is a content analysis module specifically designed to analyze textual information stored in SIMSTAT for Windows data files such as responses to open-ended questions, interviews, titles, journal articles, public speeches, electronic communication, etc. The program may be used both for automatic categorization of text using a dictionary approach and manual coding. The program an apply existing dictionaries or categorization schema to a new text corpus. It also facilitates the development and validation of new dictionaries. When used in conjunction with manual coding, the program can provide assistance for a more systematic application of coding rules, help uncover differences in word usage between subgroups of individuals, assist the revision of existing coding using KWIC (Key-Word-In-Context) tables, and assess the reliability of coding by the computation of inter-raters agreement statistics.
