Filters in the ViaSay Chatbot platform are tools used to trigger specific bot actions based on user messages. These filters are applied before the message is processed by the NLP engine. If no filter matches, the message is then passed to the NLP engine for further processing. Filters are built using RegEx and are applied sequentially, meaning the first match will trigger the associated bot action. Each instance can have up to 10 filters, which should be used judiciously as they can override NLP predictions.
Key Points:
Trigger Actions: Filters can trigger bot actions before NLP processing.
RegEx Based: Filters are defined using regular expressions.
Sequential Application: Filters are applied in order, with the first match stopping further checks.
Limitations: Each instance is limited to 10 filters.
