File Viewer node

When you are mining a collection of documents, you can specify the full path names of files directly into your Text Mining modeling nodes. However, when outputting to a Table node, you will only see the full path name of a document rather than the text within it. The File Viewer node can be used as an analog of the Table node and it enables you to access the actual text within each of the documents without having to merge them all together into a single file.

The File Viewer node can help you better understand the results from text extraction by providing you access to the source, or untranslated, text from which concepts were extracted since it is otherwise inaccessible in the stream. This node is added to the stream after a File List node to obtain a list of links to all the files.

The result of this node is a window showing all of the document elements that were read and used to extract concepts. From this window, you can click a toolbar icon to launch the report in an external browser listing document names as hyperlinks. You can click a link to open the corresponding document in the collection. See the topic Using the File Viewer Node for more information.

You can find this node on the IBM® SPSS® Modeler Text Analytics tab of nodes palette at the bottom of the IBM SPSS Modeler window. See the topic IBM SPSS Modeler Text Analytics nodes for more information.

Note: When you are working in client-server mode and File Viewer nodes are part of the stream, document collections must be stored in a Web server directory on the server. Since the Text Mining output node produces a list of documents stored in the Web server directory, the Web server's security settings manage the permissions to these documents.
