WordStat Overview
WordStat, a text analysis module by Provalis Research, offers a range of features that can be highly beneficial in the context of customer service, particularly when integrated with AI-driven tools. Here are the main features and how they work:
Automatic Categorization and Text Mining
WordStat allows for automatic categorization of text using dictionary approaches or various text mining methods. This feature is crucial in customer service as it enables the categorization of customer feedback, complaints, or inquiries into meaningful categories, such as product issues, billing queries, or service complaints. This categorization can be done using existing dictionaries or by developing and validating new ones.
Keyword-In-Context (KWIC) Tables
KWIC tables display keywords within their context, allowing users to see how words or phrases are used in the original text. This feature is valuable for analyzing customer feedback, as it helps in identifying specific issues or sentiments expressed by customers. Users can sort these tables based on various criteria, such as case number, words with context, or independent variables, and even jump to the original text for further analysis.
Exploratory Data Analysis and Graphical Tools
WordStat includes numerous exploratory data analysis and graphical tools, such as hierarchical clustering, multidimensional scaling analysis, correspondence analysis, and heatmap plots. These tools help in exploring relationships between the content of documents and other variables like the gender or age of the respondent. In customer service, this can help identify patterns in customer feedback that are associated with specific demographics or issues.
Machine Learning Algorithms
WordStat incorporates machine learning algorithms like Naive Bayes and K-Nearest Neighbors for document classification. These algorithms can be used to classify customer inquiries automatically, helping in the efficient routing of issues to the appropriate support agents. The software also supports various validation methods, such as leave-but-one and n-fold cross-validation, to ensure the accuracy of the classification models.
Multilingual Support and Linguistic Tools
WordStat 6 offers improved linguistic support with integrated dictionaries and thesauruses for multiple languages, including English, French, Spanish, German, and Portuguese. This is particularly useful in global customer service operations where support is provided in multiple languages. The software also includes an automatic suggestion feature that shows related words (synonyms, antonyms, hyponyms, etc.) for the selected items, aiding in the development of taxonomies and content analysis dictionaries.
Data Import and Export
WordStat allows data to be imported from and exported to various file formats, including Excel, SPSS, and comma or tab-separated text files. This flexibility is essential for integrating WordStat with other customer service tools and databases, ensuring seamless data exchange and analysis.
Automated Text Preprocessing
The software includes text preprocessing features such as stemming and n-grams, which help in standardizing and normalizing the text data. This preprocessing is crucial for ensuring that variant forms of words are treated as single instances, which improves the accuracy of the analysis.
Integration with AI
While WordStat itself is not an AI-driven customer service tool, its features can be integrated with AI technologies to enhance customer service analytics. For example, the categorized data from WordStat can be fed into AI models for sentiment analysis or topic analysis, as described in AI customer analytics. This integration can help in predicting customer churn risks, improving agent performance, and enhancing overall customer experience.

Customization and Transparency
WordStat stands out for its transparency and customization options. Users can customize the sentiment dictionary, develop their own dictionaries, and adjust for negations and double negations. This level of customization is not available in other CAQDAS tools, making WordStat more flexible and reliable for specific use cases.
Processing Efficiency
WordStat is highly efficient in processing large amounts of text data. It can handle up to 25 million words per minute and has enhanced its initial text processing speed in the 2024 version, making it up to three times faster for projects with many small documents.
Language Detection and Multilingual Support
The software includes an advanced language identification model that can accurately identify 37 languages with an accuracy of above 98% for small text segments and above 99.5% for longer documents. This feature is particularly useful for analyzing multilingual datasets.
Limitations and Areas for Improvement
While WordStat performs well, there are some limitations to consider:
- Performance on Specific Data Types: WordStat and other CAQDAS tools show significantly lower performance on Twitter data compared to other types of data like product reviews or course evaluations.
- Text Formatting Issues: Importing PDF documents can sometimes introduce minor imperfections such as hyphens, carriage returns, and mixed-up lines from different columns, which can affect the accuracy of phrase identification and word co-occurrence analysis. However, WordStat has implemented measures to convert PDFs into editable formats to mitigate these issues.
Conclusion
In summary, WordStat is a reliable and accurate tool for sentiment analysis and text mining in customer service contexts, with strong customization options and efficient processing capabilities. However, users should be aware of potential issues with certain types of data and text formatting.
