Segall Fig. . Concept Links for Term of statistical in SAS Text Miner using SASPDF-SYNONYMS text file Woodfield 2004 SAS Text Miner uses the drag-and-drop principle by dragging the selected icon in the tool set to dropping it into the workspace. The workspace of SAS Text Miner was constructed with a data icon of selected animal data that was provided by SAS in their Instructor s Trainer Kit as shown in Figure 24. Figure 25 shows the results of using SAS Text Miner with individual plots for role by frequency number of documents by frequency frequency by weight attribute by frequency and number of documents by frequency scatter plot. Figure 26 shows Concept Linking Figure as generated by SAS Text Miner using SASPDF-SYNONYMS text file. Megaputer PolyAnalyst Previous work by the authors Segall and Zhang 2006 have utilized Megaputer PolyAnalyst for data mining. The new release of PolyAnalyst version includes text mining and specifically new features for text OLAP on-line analytical processing and taxonomy based categorization which is useful for when dealing with large collections of unstructured documents as discussed in Megaputer Intelligence Inc. 2007 . The latter cites that taxonomy based classifications are useful when dealing with large collections of unstructured documents such as tracking the number of known issues in product repair notes and customer support letters. According to Megaputer Intelligence Inc. 2007 PolyAnalyst provides simple means for creating importing and managing taxonomies and carries out automated categorization of text records against existing taxonomies. Megaputer Intelligence Inc. 2007 provides examples of applications to executives customer support specialists and analysts. According to Megaputer Intelligence Inc. 2007 executives are able to make better business decisions upon viewing a concise report on the distribution of tracked issues during the latest observation period .
