Updating an LxBase

In i2 TextChart, the LxBase is the collection of linguistic rules and dictionary entries that govern text extraction. From time to time, i2 publishes updates that you can apply to the LxBase in your installation.

Procedure

To update your LxBase, you use the TextChart Text Analytics Configuration application to provide i2 TextChart with the location of a ZIP file that contains the new information.

  1. Open the configuration application and select the Assets tab:


    Assets configuration dialog

  2. Click Import LxBase navigate to the new ZIP file, and click Open.


    Open LxBase ZIP file

    i2 TextChart automatically updates your LxBase with information from the file.

  3. When the following dialog appears, click OK:


    LxBase update success

    The changes and updates will take effect when you restart Analyst's Notebook.

Note: i2 TextChart backs up the previous version of your LxBase in C:\ProgramData\TextChart, in a directory named LxBase-backup-<TIMESTAMP>. To restore a backup, delete the LxBase directory, and then rename the backup to LxBase.
