dialoguekit.nlu.disjoint_dialogue_act_extractor

Dialogue act extractor with disjoint intent classification and slot filling.

It is assumed that the intent classifier assigns a single intent to the utterance that corresponds to the slot-value pairs extracted by the slot-value annotators.

class dialoguekit.nlu.disjoint_dialogue_act_extractor.DisjointDialogueActExtractor(intent_classifier: dialoguekit.nlu.intent_classifier.IntentClassifier, slot_value_annotators: List[dialoguekit.nlu.slot_value_annotator.SlotValueAnnotator])

Bases: dialoguekit.nlu.dialogue_acts_extractor.DialogueActsExtractor

Initializes the dialogue act extractor.

Parameters:

• intent_classifier – Intent classifier.

• slot_value_annotators – List of slot-value annotators.

classify_intent(utterance: dialoguekit.core.utterance.Utterance) → dialoguekit.core.intent.Intent

Classifies the intent of a given agent utterance.

annotate_slot_values(utterance: dialoguekit.core.utterance.Utterance) → List[dialoguekit.core.slot_value_annotation.SlotValueAnnotation]

Annotates a given utterance with slot-value annotators.

Parameters:

utterance – Utterance to annotate.

Returns:

List of annotations.

extract_dialogue_acts(utterance: dialoguekit.core.utterance.Utterance) → List[dialoguekit.core.dialogue_act.DialogueAct]

Extracts a single dialogue act from an utterance.

Parameters:

utterance – Utterance.

Returns:

List with one dialogue act.

save(path: str) → None

Saves the intent classifier and slot-value annotators to a folder.

Parameters:

path – Path to save the dialogue act extractor.

classmethod load(path: str) → DisjointDialogueActExtractor

Loads the intent classifier and slot-value annotators from a folder.

Parameters:

path – Path to folder with intent classifier and slot-value annotators.
