Pipeline is associated with the model.</p>
<p>An NLP pipeline is a container for the sequence of processing components that take the input text at the beginning
of the pipeline and produce the list of <a href="NCVariant.html">variants</a> at the end of the pipeline.
Schematically the pipeline looks like this:</p>
<pre>
+----------+ +-----------+ +--------+
*=========* +---------+ +---+-------+ | +---+-------+ | +---+-----+ |
: Text : -> | Token | -> | Token | | -> | Token | | -> | Entity | | ----.
: Input : | Parser | | Enrichers |--+ | Validators |--+ | Parsers |--+ \
*=========* +---------+ +-----------+ +------------+ +---------+ \
}
+--------+ +--------+ +-----------+ +----------+ /
*============* +---+-----+ | +---+-----+ | +---+--------+ | +---+-------+ | /
: Variants : <- | Variant | | <- | Entity | | <- | Entity | | <- | Entity | | <-'
: List : | Filters |--+ | Mappers |--+ | Validators |--+ | Enrichers |--+
*============* +----- ---+ +----- ---+ +------------+ +-----------+
</pre>
<p>The result variants are then passed further to the intent matching. Note that only one token parser
and at least one entity parser is required for the minimal pipeline.</p>
