About WordStat:
WordStat is a content analysis and text mining module specifically
designed to analyze textual information such as responses to open-ended
questions, interviews, titles, journal articles, public speeches,
electronic communications, etc. It provides numerous statistical and
graphical tools to visualize text and examine the relationship between
words or categories of words and the values of categorical and numerical
variables (cluster analysis, multidimensional scaling, proximity plot,
correspondence plot, heatmap, bar chart, line chart, crosstabulation,
statistical association measures, etc.). Such tools allow users to
compare how different groups differ in vocabulary usage, discussed topic,
or content category. They also may be used to uncover existing
relationships between specific categories of words and numeric variables
such as age of the respondent, year of publication, etc.WordStat can
analyze text directly or apply categorization dictionaries to group words
with similar meanings . The program also provides numerous tools to
facilitate the development and validation of new categorization
dictionaries.

PRE-RELEASED VERSION OF CODEMINER 0.9 (BETA VERSION)
We are also working on a new text management and qualitative analysis
software. This new software will be offered as an optional base module
for WordStat. It will provide an easy way to manage documents and perform
common qualitative analysis tasks such as:
- Storing of documents in Rich Text Format with support for graphics,
tables, etc..
- Easy creation and edition of qualitative analysis coding systems.
- Drag and drop assignment of codes to text segments.
- Code retrieval, code comparison statistics, and text searching tools.
- Numerous visualization tools such as bar charts, line charts and
correspondence analysis plots, clustering, concept mapping (using
multidimensional scaling), and heatmaps.
- Code sequences analysis.
- Computation of 4 levels of inter-raters agreement (occurrence,
frequency, code importance and coded segments).
- Ability to perform content analysis / text mining with the optional
WordStat addon module on entire documents or on selected coded segments.
- Ability to perform statistical analysis on project files using
Simstat statistical software.
- Saving of segments and comparison tables to disk (text, comma
separated value, Excel, etc.)
While CodeMinder is still under beta testing, some people have
expressed the wish to purchase the product immediately. We have thus
decided to offer a pre-released version of CodeMiner at a special price
(almost 50% off the planned retail price). Customers who will purchase
this pre-released version will receive by email an electronic license
file to unlock the beta version. When CodeMiner will be officially
released, they will receive the final version for free (installation CD
and manual). They will also be entitled to the same benefits as users who
will purchase the official version 1.0.
