ULTIMO RILASCIO: Maggio 2016

WordStat is a flexible and easy-to-use text analysis software – whether you need text mining tools for fast extraction of themes and trends, or careful and precise measurement with state-of-the-art quantitative content analysis tools. WordStat‘s seamless integration with SimStat – our statistical data analysis tool – and QDA Miner – our qualitative data analysis software – gives you unprecedented flexibility for analyzing text and relating its content to structured information, including numerical and categorical data.

 

What it is used for?

WordStat can be used by anyone who needs to quickly extract and analyze information from large amounts of documents. Our content analysis and text mining software is used for:

Content analysis of open-ended responses, interview or focus group transcripts
Business intelligence and competitive web sites analysis
Information extraction and knowledge discovery from incident reports, customer complaints
Content analysis of news coverage or scientific literature
Automatic tagging and classification of documents
Fraud detection, authorship attribution, patent analysis
Taxonomy development and validation

 

WORDSTAT CONTENT ANALYSIS DICTIONARIES

Many WordStat users develop their own content analysis dictionaries. Such dictionaries are usually customized to the type of data being analyzed and to the variables that need to be measured. However, having access to existing dictionaries from others authors may be useful in many ways. It allows the analyst to easily assess other dimensions and quickly get a different perspective on his text data. It also makes his results comparable to those published in other studies. Such dictionaries may also represent a great source of inspiration for developing one’s own dictionary.

 

WORDSTAT SOFTWARE DEVELOPMENT KIT (SDK)

The WordStat software development kit (SDK) provides a solution , allowing models developed with the WordStat desktop tool to be used in other applications written in other computer languages such as C++, Delphi, C#, VB.Net and so on.

 

An example of such integration would be the application of a categorization model on a company data collection system of customer feedback in order to automatically measure references to specific topics and to classify those feedbacks as either positive, negative or neutral.
