Features

Aquad provides functions for content analysis, including:

  • Text search: looking for segments in texts
  • Classifying: labeling text, audio, image, and videos data
  • Writing memos (annotation): inserting annotations linked to parts or whole texts, audios, photos, or videos
  • Word analysis: counting words according to criteria
  • Retrieval by file name, code, keyword, or content: Retrieval of segments according to criteria
  • Tabular analysis: constructing tables combining criteria and arranging data in rows and columns
  • Construction of linkage hypotheses: looking for relationships across data
  • Comparison of cases/files: contrasting coding across files
  • Sequential analysis: objective hermeneutics
  • Comparison of cases by Boolean analysis: critical features and identification of "types" as introduced by Charles Ragin.
  • Export data: quantitative software as R, SPSS, and PSPP for statistical analysis.

Data context

Data can be directly analyzed on the screen (one-step) or outside (two-steps). One-step allows on-screen coding with digitized data. Two-steps allows the user to enter codes on the screen, keeping the documents on the desk or in other means such as cameras, TVs, etc. For instance, two-steps allows the analysis of recordings, diaries, incunabula, or objects without transcribing, taking photos, or scanning them.[3][4]

Comparison of cases/files by Boolean analysis

Aquad allows comparison of cases/files by "logical minimization", by using its own algorithm and the R package qualitative comparative analysis to determine implicants .[5]

Versions

The latest available version is Aquad 8, which is available in German, English, and Spanish. Version 7 is also available for download.[1]
