Configuring language settings in text predictions
Define the languages to use with your text prediction and control how the prediction detects languages in an analyzed document. For example, you can enable a fallback language in case your text prediction does not detect the language when analyzing content that is written in multiple languages.
You can also configure a spell checker to categorize the text with a greater confidence score, making the analysis more accurate and reliable. The spell checker feature is available only for topic analysis. You can use English, Spanish, French, and German default dictionaries. You can also upload custom dictionaries that best suit your business needs. Each spell checker decision data rule can have multiple language dictionaries associated with it. Each dictionary decision data object has the following properties:
- Language
- Indicates the language of the dictionary.
- Spell Checker Property
- Contains text files with dictionary entries. You can classify the text files into different categories, such as Main, Supplemental, and so on.
- Open the text prediction:
- In the navigation pane of App Studio, click Channels.
- In the Current channel interfaces section, click the icon that represents a channel for which you want to configure the text prediction.
- On the channel configuration page, click the Behavior tab, and then click Open text prediction.
- In the Prediction workspace, click the Settings tab, and scroll down to the Language settings section.
- To define the languages that you want to use in this text prediction, in the
Languages field, select one or more languages for the
text that you want to analyze.
