QDA Miner 3.0
The Mixed Method Solution for Qualitative Analysis |
LIST OF
FEATURES
TEXT
MANGEMENT AND QUALITATIVE
ANALYSIS FEATURES
This new qualitative data analysis software provides an
easy way to manage documents, and perform common qualitative analysis tasks.
Text management features:
- Storing and editing of documents in Rich Text format.
- Project files organized by cases, each case can contain up to 2030
variables including multiple documents, numeric, nominal/ordinal, date
or Boolean values.
- Importation from various file format such as Excel, Access, Paradox,
dBase, etc.
- Document conversion wizard allows one to easily import documents from
various file format (DOS ASCII, Windows ANSI, RTF, Word, WordPerfect,
HTML PDF Acrobat, etc.) and to automatically extract numeric and alphanumeric values.
- Copy, backup and restore existing projects files.
- Cases may be grouped by any numeric, nominal or ordinal variable.
- Easy filtering of cases.
Coding features:
- Easy creation and edition of codebooks.
- Fully hierarchical codebook
- Intuitive drag and drop assignment of codes to text segments.

- Notes can be assigned to projects, codes and coded segments.
- Code merging, splitting and search and replace.
- Ability to import codebooks from other projects.
TEXT RETRIEVAL
AND CODING ANALYSIS
FEATURES
- The Text Retrieval tool searches for specific text patterns
in documents. Complex search patterns may be performed using Boolean
operators, wildcards and thesaurus searches. Retrieved
paragraphs, sentences of text segments may then be coded or saved to disk (as new project, in HTML,
Excel, or delimited text files).

- The Section Retrieval tool searches structured documents for
sections bounded by fixed delimiters. This feature is useful to automatically
assign codes to recurring sections within a document or in multiple
documents.

- The Keyword Retrieval feature can retrieve any document, paragraph, sentence, or coded segment containing a specific WordStat keyword or a combination of keywords.
- The Coding Frequencies tool allows one to obtain a list of all codes in the current codebook along with their description and various statistics such as their frequency, the number of cases in which they are found, and the total number of words in the associated text segments. This dialog box also allows one to produce bar charts and pie charts from those statistics.
- The Coding Retrieval tool lists all text segments associated
with some codes or with specific patterns of codes. Complex search patterns
may include criteria such as equality, proximity, overlapping, inclusion,
sequential relationships, as well as Boolean operators (AND, OR, NOT).

- The Codes Co-occurrences tool uses information about the proximity
or the co-occurrence of codes within documents to explore potential
relationships among them as well as similarities among cases. This feature
gives access to various statistical and graphic tools such as hierarchical cluster
analysis, multidimensional scaling, and proximity plots.

- The Coding Sequences tool can be used to identify recurring
sequences of codes. This feature can produce frequency lists of all
sequences involving two selected sets of codes as well as the percentage
of times one code follows or is followed by another one.

- The Coding by Variable tool is useful for identifing or testing
potential code similarities or differences between subgroup of cases
(categorical variable) or to assess the relationship between these codes
and other numerical variables. Various statistical and graphical tools
are used for this purpose such as contingency tables, association statistics,
bar charts, line charts, heatmaps, correspondence plot, etc.
- The Inter-Coders Agreement tool is used to compare the consistency
of coding between several coders. Such a tool can be useful to uncover
differences in interpretation, clarify equivocal rules, identify ambiguity
in the text, and ultimately quantify the final level of agreement obtained
by those raters. Computes of percentage of agreement, correction for
chances (Free Marginal, Scott's Pi, and Krippendorff's alpha), list
of disagreements, etc.

- Optional Quantitative Content Analysis and Text Mining module. WordStat is a powerful
quantitative content analysis and text mining software. When used
as an add-on to QDA Miner, it analyzes words and phrases found
in specific documents or in selected coded segments. WordStat
can perform simple descriptive analysis or explore in greater
details the relationships between words or categories of words
and other numeric or categorical variables.
- Optional Statistical Analysis module. Simstat
is a comprehensive statistical analysis application. Since it
uses the same file format as QDA Miner, Simstat can be used to
perform statistical analysis on any numerical data stored in a
QDA Miner project file. It can also perform numeric and alphanumeric
computation, transformation and recoding of variables, as well
as advanced file management procedures such as data file merging,
file aggregation, etc.
MISCELLANEOUS
FEATURES
Multilingual interface
- The program interface is currently available in English and in French.
A Spanish version should be available soon. Contact us for information
on the availability of other languages.
Output features
- Saving of tabular outputs to disk in HTML, XML, plain text, comma or tab separated
value, MS Word or Excel format.
- Saving of graphics to disk and to clipboard as bitmaps, metafiles, JPG or PNG files.
- Documents may be exported to disk in plain text, RTF or HTML.
- Whole projects, including tagged documents, may be exported to disk in XML format.
Multi-users features
- The Security/Multi-Users feature allows to control users privileges
and restrict access of selected features (prevent modification to documents,
variables, or cases, prevent viewing codes assigned by other users,
etc.).

- The MERGE feature allows one to combine two or more project files
into a single one, allowing one to synchronize one's own work performed
on different computers. As well, both an individual or various team
members may work on the same set or different sets of documents and
then merge them along with their associated codings into a single master
project.
