Working with Libraries
The resources used by the extraction engine to extract and group terms from your text data always contain one or more libraries. You can see the set of libraries in the library tree located in the upper left part of the Template Editor and Resource Editor. The libraries are composed of three kinds of dictionaries:
- Type dictionaries
- Substitution dictionaries
- Exclude dictionaries
See the topic About Library Dictionaries for more information.
The resource template or the resources from the TAP you chose includes several libraries to enable you to immediately begin extracting concepts from your text data. However, you can create your own libraries as well and also publish them so you can reuse them. See the topic Publishing Libraries for more information.
For example, suppose that you frequently work with text data related to the automotive industry. After analyzing your data, you decide that you would like to create some customized resources to handle industry-specific vocabulary or jargon. Using the Template Editor , you can create a new template, and in it a library to extract and group automotive terms. Since you will need the information in this library again, you publish your library to a central repository, accessible in the Manage Libraries dialog box, so that it can be reused independently in different stream sessions .
Suppose that you are also interested in grouping terms that are specific to different subindustries, such as electronic devices, engines, cooling systems, or even a particular manufacturer or market. You can create a library for each group and then publish the libraries so that they can be used with multiple sets of text data. In this way, you can add the libraries that best correspond to the context of your text data.
Note: Additional resources can be configured and managed in the Advanced Resources tab. Some apply to all of the libraries and manage nonlinguistic entities, fuzzy grouping exceptions, and so on. Additionally, you can edit the text link analysis pattern rules, which are library-specific, in the Text Link Rules tab as well. See the topic About Advanced Resources for more information.
