BertCluAnnotator

public class BertCluAnnotator

API for BERT-based Conversational Language Understanding.

The API expects a Bert based TFLite model with metadata populated. The metadata should contain the following information:

input_process_units for Wordpiece Tokenizer.
3 input tensors with names "ids", "mask" and "segment_ids".
6 output tensors with names "domain_task/names", "domain_task/scores", "intent_task/names", "intent_task/scores", "slot_task/names", and "slot_task/scores".

class BertCluAnnotator.BertCluAnnotatorOptions Options for setting up a BertCluAnnotator.

CluResponse	annotate(CluRequest cluRequest) Annotates the input utterances.
static BertCluAnnotator	createFromBufferAndOptions(ByteBuffer modelBuffer, BertCluAnnotator.BertCluAnnotatorOptions options) Creates a `BertCluAnnotator` instance with a model buffer and `BertCluAnnotator.BertCluAnnotatorOptions`.
static BertCluAnnotator	createFromFile(Context context, String modelPath) Creates a `BertCluAnnotator` instance from a filepath.

synchronized void	close() Release the memory allocated from C++ and deregister the library from the static holder.
long	getNativeHandle()
boolean	isClosed()
