Select the Text Miner node, and then Click the button for the Interactive property. The Text Miner — Interactive window opens.

View the terms in the Terms window. The terms are sorted in decreasing order of frequency.

View the documents in the Documents window. Click the Toggle Show Full Text icon on the toolbar to see the full text contained in SYMPTOM_TEXT.

View the clusters in the Clusters window.

Select a term that is related to an adverse reaction that you want to investigate further. For example, select fever under the TERM column of the Terms window. Right-click on the term and select Filter Terms.

Note how the documents displayed and cluster frequencies change. Only those documents containing fever are displayed. Moreover, only the documents containing fever are counted. If the full text of the document is not shown, click the Toggle Show Full Text icon on the toolbar.

Click the Undo icon on the toolbar. This removes the filter that was applied and restores the display that was shown when you opened the Text Miner — Interactive window.

Select fever in the Terms window, and then right-click fever and select View Concept Links. The Concept Linking window opens. Concept linking is a way to find and display the terms that are highly associated with the selected term in the Terms table. The selected term is surrounded by the terms that correlate the strongest with it. The Concept Linking window shows a hyperbolic tree graph with fever in the center of the tree structure. It shows you the other terms that are strongly associated with the term fever. To expand the Concept Linking view, right-click on any of the terms that are not in the center of the graph and select Expand Links.

Look at the clusters in the Clusters window. Can you tell what they are about from the descriptive terms displayed? Do some clusters look vague or unclear?

Choose one of the clusters that looks vague or unclear. This is fairly subjective, but, for this example, you can use Cluster 2 as an example of a vague or unclear cluster. Right-click on Cluster 2 and select Filter Clusters. This action filters the results to show only those documents and terms that are relevant to Cluster 2. All the documents shown in the Documents window are contained in Cluster 2, and terms are now ordered by frequency within that cluster. Read the text of some of the documents in this cluster. Does this clarify the cluster better?

Click the Undo icon on the toolbar to undo any filters.
