SHORT DESCRIPTION

Quote from the home page: “This web-based tool enables you to "scrub" (clean) your unicode text(s), cut a text(s) into various size chunks, manage chunks and chunk sets, tokenize with character- or word- Ngrams or TF-IDF weighting, and choose from a suite of analysis tools for investigating those texts. Functionality includes building dendrograms, making graphs of rolling averages of word frequencies or ratios of words or letters, and playing with visualizations of word frequencies including word clouds and bubble visualizations. To facilitate subsequent text mining analyses beyond the scope of this site, users can also transpose and download their matricies of word counts or relative proportions as comma- or tab-separated files (.csv, .tsv).”

This is probably one of the best on-line tools. It allows for quite sophisticated analysis and also explains various options.

This tool also is a very good preparation tool. Scrubbed texts can be downloaded as *.zip files for further analysis.
