CRAWDAD TEXT ANALYSIS SOFTWARE

Crawdad Text Analysis Software is meant for academics and other researchers looking for a state-of-the-art computerized text analysis tool.

Crawdad is built on a patented technique, Centering Resonance Analysis (CRA; Corman, Kuhn, McPhee, & Dooley, 2002), which uses computational linguistics to model a text as a network of words. The networks constructed by CRA can then be visualized and mathematically analyzed using graph theory. CRA measures a word’s significance, or influence, according to the position of the word in the CRA Network. Influential words are those that create coherence in the text, like boundary spanners in social network.

CRA is different from traditional methods based on word frequency, such as latent semantic analysis, because it uses grammatical rules to understand how words are being used in context. Whereas word frequency methods create insight based on a “pile of words”, CRA creates insight through applying network analysis.

Crawdad Text Analysis Software provides key word scores, concept mapping, browsing, full-text search, comparison between texts, automated clustering of a set of texts, and theme analysis based on a factor analysis approach.

If you normally hand-code your data, you'll find that Crawdad Text Analysis Software will cut your data coding time by 95%, and your results will be completely reliable. If you've used other computerized text analysis software before, you'll find Crawdad both analytically powerful and easy to use.
