Cassandre :: Documentation

  1. Introduction
  2. What's in the Corpus
  3. How to make the analytical framework

Cassandre was designed in order to assist qualitative analysis in humanities and social sciences. It is used in Human Resources management, in Communication, in consulting, in R&D et in humanities and social sciences (sociology, anthropology, geography, economic sciences, philology, psychology, learning, pedagogy, philosophy...).

Cassandre helps to combine one (or several) texts corpus(es) and one (of several) analytical framework(s). Although it can be used as a desktop application, the software is designed to support collaborative work.

How it works

Cassandre helps the researchers to build analytical frameworks consistent with their hypotheses. With such a companion, the researchers chooses, in the material, keywords or idioms as accurate candidate surrogates for investigated phenomena. The software finds all excerpts that belong these keywords/idioms, so that all exerpts related to a phenomenon can be compared. Comparisons help to refine the hypotheses or raise new questions. And so on, the interactive analysis goes on...

How to compose a corpus

A corpus is a set of texts. Texts are gathered by the researcher. The more relevant for the studied matter the chosen documents are, the higher quality of the analysis. In sociale sciences, corpus are often made of interviews or focus groups, to which press releases, official documents, technical reports... can be added.

Texts Content

If the corpus is based on verbal interactions (conversation, public declaration, political discourse, interview,...), every phrase has to be transcribed. The complete transcription comprises no abbreviation. Carriage returns with each speaker change allow the texts to be structured in paragraphs. Modern text processors features spell checkers which underlines misprints, that can quicky be identified.

When transcripts include various speakers (interview, conversation, focus group), the speaker name is mentioned before each turn, in one word and followed by a typographic space and a colon (:).

Analytical frameworks are made of registries, each of them composed of markers. Registries stands for the label chosen by the researcher to depict the investigated phenomena. Markers are keywords or idioms (occuring in the analysed material) that exhibit the phenomenon at glance.

framework - registries - markers

While analysing the qualitative material, the researcher constantly create, modify or refine markers; the system renders an updated view of the analytical framework at each modification, so that the software productively accompany the ongoing qualitative analysis.
