Copying Resources From Templates and TAPs

When mining text, the extraction is based not only on the settings in the Expert tab but also on the linguistic resources. These resources serve as the basis for how to handle and process the text during extraction in order to get the concepts, types, and sometimes patterns. You can copy resources into this node from a resource template, and if you are in the Text Mining node, you can also select a text analysis package (TAP).

By default, resources are copied into the node from the basic template for licensed language for your product when you add the node to the canvas. If you have licenses for multiple language, the first language selected is used to determine the template to load automatically.

At the moment that you load, a copy of the selected resources is stored in the node. Only the contents of the template or TAP are copied while the template or TAP itself is not linked to the node. This means that if this template or TAP is later updated, these updates are not automatically available in the node. In short, the resources loaded into the node are always used unless you either reload a copy of a template or TAP, or unless you update a Text Mining node and select the Use session work option. For more information on Use session work, see further in this topic.

When you select a template or TAP, choose one with the same language as your text data. You can only use templates or TAPs in the languages for which you are licensed. If you want to perform text link analysis, you must select a template that contains TLA patterns. If a template contains TLA patterns, an icon will appear in the TLA column of the Load Resource Template dialog box.

Resource Templates

A resource template is a predefined set of libraries and advanced linguistic and nonlinguistic resources that have been fine-tuned for a particular domain or usage. In the text mining modeling node, a copy of the resources from a basic template are already loaded in the node when you add the node to the stream, but you can change templates or load a text analysis package by selecting either Resource template or Text analysis package and then clicking Load. For templates, you can then select the template in the Load Resource Template dialog box.

Note: If you do not see the template you want in the list but you have an exported copy on your machine, you can import it now. You can also export from this dialog box to share with other users. See the topic Importing and Exporting Templates for more information.

Text Analysis Packages (TAPs)

A text analysis package (TAP) is a predefined set of libraries and advanced linguistic and nonlinguistic resources bundled with one or more sets of predefined categories. IBM® SPSS® Modeler Text Analytics offers several prebuilt TAPs for English language text and also for the Japanese language text, each of which is fine-tuned for a specific domain. You cannot edit these TAPs but you can use them jump start your category model building. You can also create your own TAPs in the interactive session. See the topic Loading Text Analysis Packages for more information.

Using the "Use Session Work" option (Model tab)

While resources are copied into the node in the Model tab, you might also make changes later to the resources in an interactive session and want to update the text mining modeling node with these latest changes. In this case, you would select the Use session work option in the Model tab of the text mining modeling node.

If you select Use session work, the Load button is disabled in the node to indicate that those resources that came from the interactive workbench will be used instead of the resources that were loaded here previously.

To make changes to resources once you've selected the Use session work option, you can edit or switch your resources directly inside the interactive workbench session through the Resource Editor view. See the topic Updating Node Resources After Loading for more information.
