Quantitative Discourse Analysis Package

Quantitative Discourse Analysis Package (qdap) is an R package for computer assisted qualitative data analysis, particularly quantitative discourse analysis, transcript analysis and natural language processing. Qdap is installable from, and runs within, the R system.

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.

Alternatives

• KH Coder (Windows, Linux, macOS) for quantitative content analysis and text mining.
