Qdap is a tool for quantitative analysis of qualitative transcripts and therefore provides a bridge between quantitative and qualitative research approaches. It is designed for transcript analysis, but its features overlap with natural language processing and text mining.
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.
