text mining
Text mining, also referred to as ''text data mining'', similar to text analytics, is the process of deriving high-quality information from text. It involves "the discovery by computer of new, previously unknown information, by automatically extract ...
.
Its features include:
* tools for the preparation of transcript data
* frequency counts of sentence types, words, sentences, turns of talk, syllables
* aggregation using grouping variables
* word extracting and visualization
* statistical analysis.
For higher level statistical analysis and visualization of text, qdap is integrated with
R and offers integration with other R packages.
