TextSTAT is a simple programme for the analysis of texts. It reads plain text files (in different encodings) and HTML files (directly from the internet) and it produces word frequency lists and concordances from these files. This version includes a web-spider which reads as many pages as you want from a particular website and puts them in a TextSTAT-corpus. The new news-reader, too, puts news messages in a TextSTAT-readable corpus file. TextSTAT reads MS Word and OpenOffice files. No conversion needed, just add the files to your corpus... In TextSTAT you can use regular expression which provides you with powerful search possibilities. The programme is multilingual. Because it uses Unicode internally, TextSTAT can cope with many different languages and file encodings

TAMS stands for Text Analysis Markup System. It is a convention for identifying themes in texts (web pages, interviews, field notes). It was designed for use in ethnographic and discourse research.TAMS Analyzer is a program that works with TAMS to let you assign ethnographic codes to passages of a text just by selecting the relevant text and double clicking the name of the code on a list. It then allows you to extract, analyze, and save coded information. TAMS Analyzer is open source; it is released under GPL v2. The Macintosh version of the program also includes full support for transcription (back space, insert time code, jump to time code, etc.) when working with data on sound files.
