QDA Miner和WordStat软件发布了最新版本，带来了多项改进和新功能，包括WordStat 8.0.13版本中主题建模速度提升8倍、高分辨率Scree图和重新设计的因子载荷表等。此外，还新增了文档转换向导功能、WordStat 8文档浏览器中的主题建模选项以及用于验证聚类分析的轮廓图。这些更新旨在提升用户体验和分析效率，帮助用户更轻松地进行文本分析和数据挖掘。

🤔 **WordStat 8.0.13版本主题建模速度提升8倍:** 该版本利用因子分析技术，显著提升了主题建模速度，并提供了高分辨率的Scree图和重新设计的因子载荷表，方便用户更直观地理解分析结果。

🚀 **新增文档转换向导功能:** 新功能简化了从结构化文档（如Factiva和Lexus Nexus）中提取输出的过程，用户可以通过修改提取规则编辑器，选择要导入分析的文本行和字符位置，实现更便捷的数据导入。

🔍 **WordStat 8文档浏览器中新增主题建模选项:** WordStat 8的文档浏览器工具可以直接在Windows资源管理器中浏览文档内容，无需创建项目。新版本在此基础上增加了主题建模功能，用户只需右键点击即可执行主题建模、语义搜索、分类字典应用和机器学习分类等任务。

📊 **新增轮廓图用于验证和解读聚类分析结果:** 在聚类树状图中新增了轮廓图，帮助用户验证和解读聚类分析结果。轮廓图可以显示哪些词语或短语可能被错误分类或位于聚类之间，并识别清晰的聚类与较弱的聚类。

Make sure you download the latest version of QDA Miner and WordStat because we are always fixing small issues and adding new features. For example, this month we released WordStat 8.0.13.

A new Document Conversion Wizard capability, topic modeling option in Document Explorer of WordStat 8 and a Silhouette plot to validate cluster analysis. All this and we have barely completed February. Stay tuned to our website, our Newsletter, and our social media feeds for more announcements in 2019. You won’t be disappointed! See descriptions and screenshots of three new features below!

New Document Conversion Wizard feature

The lastest update of QDA Miner and WordStat includes a new feature in the Document Conversion Wizard that allows you to more easily extract output from structured documents such as Factiva and Lexus Nexus. The extraction rule editor has been modified to let you select the line and the character position of the text you wish to import for analysis. Download the latest version here.

 

Topic modeling now available with Document Explorer in WordStat 8

In WordStat 8 we introduced the Document Explorer tool allowing you to explore the content of your documents from Windows Explorer without the need to run WordStat and create a project. Now we have gone one step better. We added topic modeling to word and phrase extraction. With a simple-right click you can perform these tasks as well as perform a semantic search, using a categorization dictionary or apply machine learning to classify documents.

 

 

New silhouette plot for validation & interpretation of cluster analysis results

A new feature in our clustering dendrogram, a silhouette plot, helps you to validate and interpret cluster analysis results. The silhouette plot shows which words or phrases may be misclassified or lie in between clusters. It also enables you to identify clear cut clusters from weaker ones.
