Dragon ToolkitThe Dragon ToolKit (Version 1.3.3 2008/01/06). Designed for Text Retrieval and Text Mining. Another important feature of the toolkit is its scalability. Unlike many text mining tools such as Weka, the dragon toolkit is specially designed for large-scale application. The toolkit uses sparse matrix to implement text representations and does not have to load all data into memory in the running time. Therefore, it can handle hundred thousands of documents with very limited memory. How to Cite Dragon Toolkit.
