Provalis Research has announced a new version of its WordStat text mining software, which now features an Explorer mode allowing inexperienced users to quickly analyse many documents and identify the most frequent words, topics and phrases.

In Explorer mode users may also apply a categorisation dictionary to find specific themes. WordStat 8 uses a faster topic modelling protocol based on non-negative matrix factorisation. It produces topics with words and phrases and provides suggestions for additional expressions, spelling corrections and potential exceptions for better measurement of concepts.

With case sensitivity support, Regex pattern searches (Regular Expression such as email addresses or postal codes) or new substitution techniques, the customisation and sharing of the categorization process is easier and more precise.

WordStat exports text analyses to Tableau Software to prepare additional visual presentations. For better data visualisation, WordStat 8 introduces new graphs such as donut charts, 100% stacked bar charts and polar charts. A new radar chart and improved interactive word clouds allow for quick assessment of the relationship between a variable and selected keywords or phrases.

WordStat has an open interface with numerous solutions and directly imports and creates projects from Windows File Explorer, Excel, Word, PDF, Stata, CSV, social media, web survey platforms, and reference manager tools. To speed up the data analysis, WordStat 8 allows data analysts to pre-process or transform text documents using Python scripts. WordStat can still be run as a content analysis tool within QDA Miner, Stata or SimStat.

“WordStat 8 has amazing depth,” says Dr. Grant Blank from the Oxford Internet Institute of the University of Oxford.

“WordStat can easily display individual text segments, reveal synonyms for individual words (along with frequency counts), do a correspondence analysis, show frequency tables, and demonstrate how topics relate to other coded text or variables,” added Blank. To access the complete capabilities of WordStat you can effortlessly switch from “Explorer” to “Expert” mode from the main menu.
