Method and apparatus for multi-party dialogue discourse parsing as a sequence generation

An apparatus comprising:

• at least one memory configured to store computer program code;
• and
• at least one processor configured to access said at least one memory and operate as instructed by said computer program code, said computer program code including:
• retrieving code configured to cause the at least one processor to retrieve a dialogue history including a plurality of speech utterances, each speech utterance including one or more words,
• encoding code configured to cause the at least one processor to encode the plurality of speech utterances such that each speech utterance is associated with a sequence identifier indicating an order of each speech utterance in the dialogue history, and
• decoding code configured to cause the at least one processor to decode the encoded plurality of speech utterances to generate at least one discourse relation triple corresponding to the dialogue history, the at least one discourse relation triple including a first sequence identifier of a first speech utterance from the plurality of speech utterances, a second sequence identifier of a second speech utterance from the plurality of speech utterances, and a dialogue discourse type.

A non-transitory computer readable medium having instructions stored therein, which when executed a processor cause the processor to execute a method comprising:

• retrieving a dialogue history including a plurality of speech utterances, each speech utterance including one or more words;
• encoding the plurality of speech utterances such that each speech utterance is associated with a sequence identifier indicating an order of each speech utterance in the dialogue history;
• and
• decoding the encoded plurality of speech utterances to generate at least one discourse relation triple corresponding to the dialogue history, the at least one discourse relation triple including a first sequence identifier of a first speech utterance from the plurality of speech utterances, a second sequence identifier of a second speech utterance from the plurality of speech utterances, and a dialogue discourse type.
